Top Cyber Stories of the Last Week
Ransomware Gangs Made At Least $350 Million In 2020
Ransomware gangs made at least $350 million in ransom payments last year, in 2020, blockchain analysis. The figure was compiled by tracking transactions to blockchain addresses linked to ransomware attacks. Although Chainalysis possesses one of the most complete sets of data on cryptocurrency-related cybercrime, the company said its estimate was only a lower bound of the true total due.

Home Working Increases Cyber Security Fears
"We see tens of different hacking attacks every single week. It is never ending."A senior computer network manager says they are bombarded from all directions. "We see everything," he says. "Staff get emails sent to them pretending to be from the service desk, asking them to reset their log-in passwords. "We see workers being tricked into downloading viruses from hackers demanding ransoms, and we have even had employees sent WhatsApp messages pretending to be from the CEO, asking for money transfers.

3.2 Billion Emails And Passwords Exposed Online
A whopping 3.2 billion password-username pairs are up for grabs in an unnamed online hacking forum. But don't panic — the data is nothing new. It's a compilation of stolen credentials from dozens of old data breaches, some going back ten years. That doesn't mean you shouldn't be aware that your old passwords are floating out there. Yes, your passwords, and ours too. Pretty much anyone who's ever created more than three online accounts has had a password compromised by now.

Account Takeover Attacks Spiked In 2020
Occurring whenever a bad actor can steal login credentials and seize control of an online account, takeover attacks rose from 34% of fraud detected in 2019 to 54% by the end of December 2020. Other methods of fraud were blips on the radar compared to account takeovers: The next most popular method, at just 16% of detected fraud, was money laundering/mule transactions, followed by new account fraud (14%), and a mere 12% of instances used remote access or hacking tools to accomplish their goals.

30% Of “Solarwinds Hack” Victims Didn’t Actually Use Solarwinds
When security last week that it had been targeted by the same attacker that compromised SolarWinds' Orion software, it noted that the attack did not use SolarWinds itself. According to Malwarebytes, the attacker had used "another intrusion vector" to gain access to a limited subset of nearly a third of the organizations attacked had no direct connection to SolarWinds.
Data Leakage Attacks Saw Huge Rise In 2020
The number of data leakage incidents grew by an “unprecedented” rate in 2020, a new report from Imperva argues. Through online means alone, not counting leaks caused by lost hardware or word of mouth, Imperva researchers tracked a 93 percent rise. By the end of the year, Imperva had identified a total of 1.7 million leaks, with the the number growing even faster in the second half of the year. Between Q3 and Q4, there was a 47 percent increase.
https://www.itproportal.com/news/data-leakage-attacks-saw-huge-rise-in-2020/
Automated Tools Increasingly Used to Launch Cyber Attacks
Cyber-criminals are increasingly making use of automation and bots to launch attacks, according to a new analysis. revealed that over half (54%) of all cyber-attacks it blocked in November and December were web application attacks which involved the use of automated tools. The most prevalent form was fuzzing attacks, making up around one in five (19.5%). This uses automation to detect and exploit the points at which applications break. This was followed by injection attacks (12%), in which cyber-criminals make use of automation tools such as sqlmap to gain access to applications.
https://www.infosecurity-magazine.com/news/automated-tools-launch-cyber/
A Second SolarWinds Hack Deepens Third-Party Software Fears
It’s been more than two months since revelations that alleged Russia-backed hackers broke into the IT management firm SolarWinds and used that access to launch a massive software supply chain attack. It now appears that Russia was not alone; Reuters reports that suspected Chinese hackers independently exploited a different flaw in SolarWinds products last year at around the same time, apparently hitting the US Department of Agriculture's National Finance Center.
https://www.wired.com/story/solarwinds-hack-china-usda/
93% Of Workers Overshare Online, Causing Security Risks
Reveals just how much, and how often, people divulge about their lives online and how attackers take advantage of it. With insights from both professionals and hackers, the report explores how cybercriminals use an abundant and seemingly cheap resource — the personal information people share on social media and in out-of-office alerts — to craft social engineering attacks.
https://www.helpnetsecurity.com/2021/02/03/workers-overshare-online/
Is There A Widening Gulf Between You And Your Remote Workers? Yes – And It’s Security Shaped
It’s been almost a year since large parts of the workforce beat a hasty retreat from their offices, and began a mass experiment in working from home, often courtesy of Microsoft 365. And after 12 or so months, it’s safe to say that the case for productive remote working has been proved, and that many workers will continue to do so even when the all clear sounds. But is there a question as to whether remote working is as secure as the traditional, office bound, hard perimeter setup? Well, yes, and it’s fair to say the jury is still very much out.

Black Arrow Cyber Threat Briefing 15 January 2021
Black Arrow Cyber Threat Briefing 15 January 2021: Two Thirds of Employees Don’t Consider Security Whilst Working from Home; Ransomware Gangs Targeting Top Execs; Microsoft emits 83 security fixes – and miscreants are already exploiting vulnerabilities in Windows Defender; Android malware gives hackers full control of your smartphone; Massive fraud campaign sees millions vanish from online bank accounts
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities and cyber related news from the last week.
Top Cyber Headlines of the Week
Two-Thirds of Employees Don’t Consider Security Whilst Home Working
More than two-thirds (68%) of UK workers do not consider the cyber security impact of working from home, according to a new study. The survey of 2043 employees in the UK demonstrated a lack of awareness about how to stay secure whilst working remotely, which is putting businesses at risk of attacks. The shift to home working as a result of COVID-19 means that staff in many organizations are operating across insecure devices and networks, providing opportunities for cyber-criminals.
https://www.infosecurity-magazine.com/news/two-thirds-employees-security-home/
Ransomware Gangs Scavenge for Sensitive Data by Targeting Top Executives
In their attempt to extort as much money as quickly as possible out of companies, ransomware gangs know some effective techniques to get the full attention of a firm’s management team. And one of them is to specifically target the sensitive information stored on the computers used by a company’s top executives, in the hope of finding valuable data that can best pressure bosses into approving the payment of a sizeable ransom.
Microsoft emits 83 security fixes – and miscreants are already exploiting one of the vulnerabilities in Windows Defender
83 vulnerabilities in its software, which does not include the 13 flaws fixed in its Edge browser last week. That's up from 58 repairs made in December, 2020, a relatively light month by recent standards. Affected applications include: Microsoft Windows, Microsoft Edge (EdgeHTML-based), Microsoft Office and Microsoft Office Services and Web Apps, Microsoft Windows Codecs Library, Visual Studio, SQL Server, Microsoft Malware Protection Engine, .NET Core, .NET Repository, ASP .NET, and Azure.

This Android malware claims to give hackers full control of your smartphone
The 'Rogue' remote administration tool (RAT) infects victims with a keylogger, allowing attackers to easily monitor the use of websites and apps in order to steal usernames and passwords, as well as financial data. The low cost of the malware reflects the increasing sophistication of the criminal ecosystem that is making it possible for wannabe crooks with limited technical skills to acquire the tools to stage attacks.
Massive fraud campaign sees millions vanish from online bank accounts
Researchers have uncovered an extensive fraud campaign that saw millions of dollars drained from victims’ online bank accounts. The operation was discovered by experts at IBM Trusteer, the IT giant’s security division, who described the attack as unprecedented in scale. To gain access to online banking accounts, the fraudsters are said to have utilized a piece of software known as a mobile emulator, which creates a virtual clone of a smartphone.
SolarWinds Hack Followed Years of Warnings of Weak Cyber Security
Congress and federal agencies have been slow or unwilling to address warnings about cyber security, shelving recommendations that are considered high priority while investing in programs that have fallen short. The massive cyber-attack by suspected Russian hackers, disclosed in December, came after years of warnings from a watchdog group and cyber security experts. For instance, the Cyberspace Solarium Commission, which was created by Congress to come up with strategies to thwart sizable cyber-attacks, presented a set of recommendations to Congress in March that included additional safeguards to ensure more trusted supply chains.

The Risks Posed by Home Routers - Cyber Tip Tuesday video
Welcome to this week's Black Arrow Cyber Tip Tuesday, this week James is talking about the security of home routers. A recent study in Germany of 127 home routers from 7 different brands including D-Link, Linksys, TP-Link and Zyxel found that almost 60 percent of models hadn't had a security update in over a year and most were affected by hundreds of known vulnerabilities. On top of that, they found that vendors were shipping updates with no fixes for critical vulnerabilities that have been known about for many years, some are even observed as being actively exploited. Most routers are based on a Linux operating system which is patched and maintained regularly but the home router manufacturers are choosing to use old and known vulnerable versions of the operating system without sending updates to customers devices.

The lesser of the evils seemed to be Asus and Netgear who both applied more security fixes more frequently but another recent study found that 79 of Netgear's routers have a critical security vulnerability that would allow a remote attacker to take complete control of the device and the network behind which has been present since 2007. With the increasing popularity of home working it is essential that both individuals and firms take in to account this increase in attack surface and apply appropriate controls and mitigations to prevent their data and their clients data from being captured by malicious third parties.
When approached correctly, home working can provide significant benefits to productivity without compromising security. Speak to us today to find out how you can achieve this.

Cyber Weekly Flash Brief 21 August 2020: Uber infosec exec charged with cover-up, 50% anti-malware products fail, WFH security breach surge, 40% of firms sacked staff for cyber breaches during Covid
Cyber Weekly Flash Briefing 21 August 2020: Former Uber security exec charged with cover-up, half of anti-malware products fail to recognise threats, millions of social media accounts compromised by data breach, WFH causes surge in security breaches, staff 'oblivious' to best practices, 40% of firms have sacked staff for cyber security breaches during Covid, HMRC Investigating Over 10,000 COVID-Related Phishing Scams

Former Uber security executive charged with data breach cover-up
Uber’s former chief security officer has been charged with obstruction of justice over accusations that he attempted to cover up a 2016 hack of the company, which exposed the personal details of 57m users and drivers.
Prosecutors said Joseph Sullivan, 52, hid the breach from the relevant authorities, and instead paid a ransom to the hackers and had them sign non-disclosure agreements stating, falsely, that they had not stolen personal information.
“The agreements contained a false representation that the hackers did not take or store any data,” prosecutors said in a press release. “When an Uber employee asked Sullivan about this false promise, Sullivan insisted that the language stay in the non-disclosure agreements.”
Mr Sullivan, who worked at Facebook prior to Uber, is said to have authorised the payment to the hackers of $100,000 in bitcoin, disguising the fee as coming via the company’s legitimate “bug bounty” programme — normally used to pay well-intentioned cyber security experts for discovering flaws and vulnerabilities.
It was not until November 2017, almost a year after Mr Sullivan allegedly knew the attack took place, that Uber revealed its knowledge of the breach and Mr Sullivan was dismissed.
Why this matters?
Not only was a criminal act conducted against Uber but a further criminal act was then conducted within the firm to cover it up. This shows what is at stake, that people will go to lengths to cover things up and that strong governance is needed and appropriate controls, and rewards, need to be in place across the organisation to encourage good behaviours.

Half of anti-malware products fail to recognize notable threats
Many of the most popular, well-established cyber security solutions do not protect their users from all notable threats, according to new analysis from SE Labs.
The security firm tested 14 of the world’s most popular cyber security solutions and, while products from Microsoft and Kaspersky Lab scored 100 percent, more than half failed to identify all threats.
"While the numbers of 'misses' are not out of this world, it's disappointing to see big brand products miss well-known threats," said Simon Edwards, CEO at SE Labs.
"Although we do 'create' threats by using publicly available free hacking tools, we don't write unique malware so there is no technical reason why any vendor being tested should do poorly."
According to SE Labs, the firm used common threats that affect the general public to conduct the tests, as well as more targeted forms of attack.
"In some cases the bad guys actually help us out, by sending our own organization the same types of malware that they use to target other potential victims. The Emotet malware campaign that ran in July of this year was a notable example," Edwards added.
With the Covid-19 pandemic forcing employees to remain at home, it has never been more important to protect devices and data from cyberthreats. Businesses and consumers alike are advised to keep their operating systems, applications and cybersecurity solutions up to date.
Why this matters:
Many firms put too much faith in technical controls, yet reports like this prove the point that technical controls are not as good as many people believe.Technical controls, even the best technical controls, only go so far when information security is a whole of business risk and people controls are needed in addition to technical controls to keep a firm safe.

Hundreds of millions of Instagram, TikTok, YouTube accounts compromised by data breach
Security researchers have discovered an exposed database online which contains scraped data from the social media profiles of nearly 235m Instagram, TikTok and YouTube users.
For those unfamiliar with the practice, web scraping is an automated technique used to gather data from websites that is often employed by analytics firms who use it to create large databases of user information. Although the practice is legal, it is strictly prohibited by social media companies as it puts the privacy of their users and their data at risk.
Researchers discovered three identical copies of the exposed database online at the beginning of August. After examining the database they learned that it belonged to a company called Deep Social which has shut down its operations.
Why this matters
Big beaches like these, where data has been taken from different sources, breaches and public databases, can give attackers an incredible amount of data on you, probably enough to then start attacking your home or your employer. Even as far as identity theft type attacks.
Working from home causes surge in security breaches, staff 'oblivious' to best practices
The COVID-19 pandemic shows little sign of slowing down, and for many businesses, employees are still working remotely and from home offices.
While some companies are gearing towards reopening their standard office spaces in the coming months -- and have all the challenges associated with how to do so safely to face -- they may also be facing repercussions of the rapid shift to remote working models in the cyber security space.
In the clamor to ensure employees could do their jobs from home, the enterprise needed to make sure members of staff had the right equipment as well as network and resource access.
However, according to Malwarebytes, the rushed response to COVID-19 in the business arena has created massive gaps in cyber security -- and security incidents have increased as a result.
On Thursday, the cyber security firm released a report (.PDF), "Enduring from Home: COVID-19's Impact on Business Security," examining the impact of the novel coronavirus in the security world.
Company telemetry and a survey conducted with 200 IT and cyber security professionals suggest that since the start of the pandemic, remote workers have caused a security breach in 20% of organisations.
As a result, 24% of survey respondents added that their organizations had to pay unexpected costs to address cyber security breaches or malware infections after shelter-in-place orders were imposed.
Why this matters:
Months into this pandemic and staff working from home many staff are still oblivious to what they should and should not be doing and some firms are not doing a good enough job of getting their staff to appreciate the role they playing in helping to keep their firm’s safe.
Two-fifths of firms have sacked staff for cybersecurity breaches during Covid, poll shows
Almost two-fifths of business decision-makers (39 per cent) have dismissed employees because of a cyber security policy breach since the pandemic began, a survey has found.
The research polled 200 UK business decision-makers and found more than half (58 per cent) of firms believed that working from home made employees more likely to circumvent security protocols – including through the use of personal laptops and failing to change passwords.
To combat poor employee security practices, more than half (55 per cent) of those surveyed had banned, or planned to ban, staff from using personal devices to work from home.
Meanwhile, 57 per cent were implementing more measures to securely authenticate employees, including biometric data checks such as fingerprint and facial recognition technology, and multi-factor authentication steps to access certain files, applications and accounts.
The poll found that almost two-thirds (65 per cent) had made substantial changes to their cybersecurity policies in response to breaches and to Covid-19.
Why this matters:
It is imperative employers revisited their data security protocols in light of widespread home working. Employers need to communicate that the same principles of data protection apply at home as in the office, including that a breach could lead to severe disciplinary action. The importance of securing data and directing employees accordingly cannot be underestimated as the employer could find themselves responsible for significant data breaches if they have not taken appropriate steps to protect it.
Separately, a report by recruitment firm Robert Walters has found that up to 65,000 cyber attacks take place on UK SMEs every day, with 4,500 successful. The report, Cyber security: Building Business Resilience, found that almost half (48 per cent) of UK companies admitted to not having adequate cyber security provision to maintain a fully remote working model.
We are at the mercy of Google's cloud services – and it could cost us dearly
If the internet is our information superhighway, this week's mass outage of Google services represents the sudden and total closure of the M25.
Users up and down the country who rely on the system for their livelihoods found themselves confronted with the simple Gmail message: “Oops, something went wrong”. It was the digital equivalent of the Road Closed sign.
Such is the public and private sector’s dependence on software services provided by Google and its rivals Amazon, Microsoft and Alibaba that the five-hour outage will likely be felt at GDP level.
Never mind the frustration felt by hundreds of thousands of homeworkers, think of all the lost opportunities from meetings unattended, the lost confidence from work unsent and the lost productivity from reduced output.
It all adds up: a temporary internet shutdown costs an advanced economy like Britain’s £107m per day according to a report from Deloitte and Facebook into the economic impact of disruptions to connectivity.
That’s equivalent to 1.9 per cent of daily GDP. A big hit, especially in a recession when companies small and large are fighting for their lives and public services are stretched to the limit.
Why this matters
Firms are increasing reliant on a small number of providers and a loss of any one of those providers could have serious ramifications for any business operating online. It is always best to diversify your critical systems across different providers such that a loss of one does not have such wide reaching impact.
Four million Britons with Huawei phones risk their devices becoming obsolete
Up to four million British consumers could be stuck with increasingly useless and vulnerable Huawei mobiles after the Chinese firm was blocked from receiving future software updates due to US sanctions.
The crisis-hit company's phones are in danger of rapidly becoming obsolete following the expiry of a temporary licence allowing it to use apps and Android updates from Google - raising fears they could become increasingly slow and laden with bugs.
Huawei is at risk of being unable to renew the licence after being blacklisted by the Trump administration in May last year, with US companies barred from selling technology to it without explicit government approval.
As a result, Huawei phones using Google Mobile Services could stop getting new features and security updates from the US company.
The US claims that Huawei equipment can be used by the Chinese government for espionage – something which Huawei has repeatedly denied. Older Huawei phones, developed before May 2019, are still expected to have the support of critical security features.
Why this matters:
Security updates need to rolled out to keen devices and software secure once vulnerabilities have been found and fixed by vendors. If Huawei phones are no longer able to receive these security updates any vulnerabilities in the underlying operating system will be able to continue being exploited by cyber criminals or ironically nation state actors.
HMRC Investigating Over 10,000 COVID-Related Phishing Scams
More than 10,000 email, SMS, social media and phone scams exploiting the COVID-19 pandemic are being investigated by Her Majesty’s Revenue and Customs (HMRC) in the UK.
The official figures, published following a Freedom of Information (FOI) request highlight how the health and economic crisis has provided major scamming opportunities for cyber criminals.
The data showed that May was the month in which the highest number of phishing scams were reported by members of the public to HMRC, at 5152, representing a 337% rise compared to March when lockdown measures were first introduced in the UK. This was followed by 2558 reports in June, and 2105 in April. The total since March comes to 10,428.
Government programs introduced to support businesses and workers impacted by the lockdown have been a common target for scammers. Examples include an email purporting to be from HMRC regarding the government’s Coronavirus Job Retention Scheme, which attempted to get business owners to reveal their bank account information, while another offered a bogus tax rebate under the guise of the Self-Employment Income Support Scheme.
The FOI also showed that 106 COVID-related websites have been requested for removal since March, with April the highest month at 42, followed by 24 in May and 17 in March. In May, it was revealed that HMRC formally asked internet service providers (ISPs) to remove 292 scam web addresses exploiting the coronavirus outbreak.
Why this matters:
Cyber criminals will always take advantage of current events, crises and tragedies to exploit unsuspecting victims. This has never been so evident as with the current Coronavirus pandemic, especially with the shift to more staff working from home.

Cyber-Criminals Impersonating Google to Target Remote Workers
Remote workers have been targeted by up to 65,000 Google-branded cyber-attacks during the first four months of 2020, according to a new report. The study found that Google file sharing and storage websites were used in 65% of nearly 100,000 form-based attacks the security firm detected in this period.
According to the analysis, a number of Google-branded sites, such as storage.googleapis.com, docs.google.com, storage.cloud.google.com and drive.google.com, were used to try and trick victims into sharing login credentials. Google-branded attacks were far in excess of those impersonating Microsoft, with the sites onedrive.live.com, sway.office.com and forms.office.com making up 13% of attacks.
Other form-based sites used by attackers included sendgrid.net (10%), mailchimp.com (4%) and formcrafts.com (2%).

Ransomware Demands Soared 950% in 2019
Ransomware operators had another standout year in 2019, with attacks and ransom demands soaring according to new data.
A new report claimed that, after a relatively quiet 2018, ransomware was back with a vengeance last year, as attack volumes climbed by 40%.
As large enterprises became an increasing focus for attacks, ransom demands also soared: from $8,000 in 2018 to $84,000 last year. That’s a 950% increase.
The “greediest ransomware families with highest pay-off” were apparently Ryuk, DoppelPaymer and REvil, the latter on occasion demanding $800,000.

Use of cloud collaboration tools surges and so do attacks
The COVID-19 pandemic has pushed companies to adapt to new government-mandated restrictions on workforce movement around the world. The immediate response has been rapid adoption and integration of cloud services, particularly cloud-based collaboration tools such Microsoft Office 365, Slack and videoconferencing platforms. A new report shows that hackers are responding to this with increased focus on abusing cloud account credentials.
Analysis of cloud usage data that was collected between January and April from over 30 million enterprise indicated a 50% growth in the adoption of cloud services across all industries. Some industries, however, saw a much bigger spike--for example manufacturing with 144% and education with 114%.
The use rate of certain collaboration and videoconferencing tools has been particularly high. Cisco Webex usage has increased by 600%, Zoom by 350%, Microsoft Teams by 300% and Slack by 200%. Again, manufacturing and education ranked at the top.
Huge rise in hacking attacks on home workers during lockdown
Hackers have launched a wave of cyber-attacks trying to exploit British people working from home, as the coronavirus lockdown forces people to use often unfamiliar computer systems.
The proportion of attacks targeting home workers increased from 12% of malicious email traffic before the UK’s lockdown began in March to more than 60% six weeks later, according to new data.
Attacks specifically aimed at exploiting the chaos wrought by Sars-CoV-2 have been evident since January, when the outbreak started to garner international news headlines.
The attacks have increased in sophistication, specifically targeting coronavirus-related anxieties rather than the more usual attempts at financial fraud or extortion.
In early May “a large malicious email campaign” was detected against UK businesses that told employees they could choose to be furloughed if they signed up to a specific website.

EasyJet faces £18 billion class-action lawsuit over data breach
UK budget airline easyJet is facing an £18 billion class-action lawsuit filed on behalf of customers impacted by a recently-disclosed data breach.
Made public on May 19, easyJet said that information belonging to nine million customers may have been exposed in a cyber attack, including over 2,200 credit card records.
The "highly sophisticated" attacker to blame for the security incident managed to access this financial information, as well as email addresses and travel details. EasyJet is still contacting impacted travelers.
The carrier did not explain how or exactly when the data breach took place, beyond that "unauthorized access" has been "closed off."
The National Cyber Security Centre (NCSC) and the UK's Information Commissioner's Office (ICO) have been notified, of which the latter has the power to impose heavy fines under GDPR if an investigation finds the carrier has been lax in data protection and security.
Last year, British Airways faced a "notice of intent" filed by the ICO to fine the airline £183.4 million for failing to protect the data of 500,000 customers in a data breach during 2018.

Data Breach at Bank of America
Bank of America Corporation has disclosed a data breach affecting clients who have applied for the Paycheck Protection Program (PPP).
Client information was exposed on April 22 when the bank uploaded PPP applicants' details onto the US Small Business Administration's test platform. The platform was designed to give lenders the opportunity to test the PPP submissions before the second round of applications kicked off.
The breach was revealed in a filing made by Bank of America with the California Attorney General's Office. As a result of the incident, other SBA-authorized lenders and their vendors were able to view clients' information.
Data exposed in the breach consisted of details relating not only to individual businesses, but also to their owners. Compromised data may have included the business address and tax identification number along with the owner's name, address, Social Security number, phone number, email address, and citizenship status.

NSA warns of new Sandworm attacks on email servers
The US National Security Agency (NSA) has published a security alert warning of a new wave of cyber attacks against email servers conducted by one of Russia's most advanced cyber-espionage units.
The NSA says that members of Unit 74455 of the GRU Main Center for Special Technologies (GTsST), a division of the Russian military intelligence service, have been attacking email servers running the Exim mail transfer agent (MTA).
Also known as "Sandworm," this group has been hacking Exim servers since August 2019 by exploiting a critical vulnerability.

DoubleGun Group Builds Massive Botnet Using Cloud Services
An operation from the China-based cybercrime gang known as DoubleGun Group has been disrupted, which had amassed hundreds of thousands of bots that were controlled via public cloud services, including Alibaba and Baidu Tieba.
Researchers in a recent post said that they noticed DNS activity in its telemetry that traced back to a suspicious domain controlling mass amounts of infected Windows devices. Analysis of the command-and-control (C2) infrastructure of the operation and the malware used to build the botnet showed that the effort could be attributed to a known threat group – DoubleGun, a.k.a. ShuangQiang.

Malicious actor holds at least 31 stolen SQL databases for ransom
A malicious cyber actor or hacking collective has reportedly been sweeping the internet for online stores’ unsecured SQL databases, copying their contents, and threatening to publish the information if the rightful owners don’t pay up.
The perpetrator has stolen the copied versions of at least 31 SQL databases, which have been put up for sale on an unnamed website. These databases constitute roughly 1.620 million rows of information, including e-commerce customers’ names, usernames, email addresses, MD5-hashed passwords, birth dates, addresses, genders, account statuses, histories and more

Maintaining Good Cyber Hygiene during the Coronavirus Crisis - Guernsey Press 24 March 2020
With more of us working from home in the coronavirus crisis, there is evidence of increasing attacks by cyber criminals who are exploiting those unaware of the risks, according to Tony Cleal, director of Guernsey’s Black Arrow Cyber Consulting BUSINESSES are making significant changes in response to the virus, including asking employees to work from home for the first time. These new practices have often been implemented as quickly as possible, with a priority on keeping the business operations going. At the same time, the cyber and information security consultants at Black Arrow are seeing reports from specialist intelligence and the wider media which show cyber criminals are feasting on the current chaos as they target employees and companies who let their guard down. ‘Cyber criminals usually target people, not technology, to get into their employer’s systems. Companies need to ensure they consider all the basic risks to prevent this, and implement layers of defence that start with the user. As an analogy, the easiest way for a criminal to get into someone’s home is to convince the resident to let them in, for example by pretending to repair an emergency gas leak. It doesn’t matter how good the window locks are, or how sophisticated the burglar alarm is; all they need to do is knock on the front door and be convincing. Thousands of coronavirus scam and malware sites are being created on a daily basis, and we see cyber criminals taking advantage of the crisis to get access to the organisation’s money and information’. That means companies and employees need to maintain good cyber hygiene when working from home, just as they do in the office. People behave differently at home, and are often less alert to information security risks than in the office. ‘We have seen Guernsey employees posting pictures on Facebook to show their new desk at home, but these pictures risk showing confidential documents on the table and screen. This is further evidence that cyber security is a business-wide risk that needs the aligned strength of people and culture, as well as business operations and technology’. Some smaller businesses consider cyber security to be more relevant for larger organisations. ‘Weakened defences will always be exploited, whether by biological viruses or malicious actors. 43% of cyber attacks hit smaller businesses, and a breach now on top of everything else would likely be catastrophic. Luckily, there are things you can do to protect yourself, even with limited resources; we can help ensure that the scarce money is spent wisely by addressing cyber security as a business-wide risk owned by the business leadership.’ Tony concluded: ‘Now more than ever, because of the disruption and changes to business practices, companies need to take appropriate steps to protect themselves against cyber-attacks. We are committed to helping improve cyber hygiene in Guernsey. This started when I used my experience in British Intelligence to lead the review of cyber security across the Bailiwick for the GFSC, which informed the forthcoming new standards. Now at Black Arrow we are reducing our prices during this crisis, to make cyber hygiene easier for all organisations; of course, charities and non-profits can continue to contact us for help free of charge.’ https://guernseypress.com/news/2020/03/24/maintaining-good-cyber-hygiene/

Working from Home: COVID-19’s Constellation of Security Challenges
Organisations are sending employees and students home to work and learn — but implementing the plan opens the door to more attacks, IT headaches and brand-new security challenges.
As the threat of coronavirus continues to spread, businesses are sending employees home to work remotely, and students are moving to online classes. But with the social distancing comes a new threat – a cyber-related one.
As organisations rush to shift their businesses and classes online, cybercriminals are ramping up their tactics to take advantage of those who may have inadequate or naive security postures as a result. Given the challenges in securing work- and learn-from-home environments, the attack surface represents an attractive opportunity for threat actors

Thousands of COVID-19 scam and malware sites are being created on a daily basis
Malware authors and fraudsters aren't letting a tragedy go to waste.
In the midst of a global coronavirus (COVID-19) pandemic, hackers are not letting a disaster go to waste and have now automated their coronavirus-related scams to industrial levels.
According to multiple reports, cybercriminals are now creating and putting out thousands of coronavirus-related websites on a daily basis.
Most of these sites are being used to host phishing attacks, distribute malware-laced files, or for financial fraud, for tricking users into paying for fake COVID-19 cures, supplements, or vaccines.
EU warns of broadband strain as millions work from home
The EU has called on streaming services such as Netflix and YouTube to limit their services in order to prevent the continent’s broadband networks from crashing as tens of millions of people start working from home.
Until now, telecoms companies have been bullish that internet infrastructure can withstand the drastic change in online behaviour brought about by the coronavirus outbreak.
But on Wednesday evening, Thierry Breton, one of the European commissioners in charge of digital policy, said streaming platforms and telecoms companies had a “joint responsibility to take steps to ensure the smooth functioning of the internet” during the crisis.

COVID-19: With everyone working from home, VPN security has now become paramount
With most employees working from home amid today's COVID-19 (coronavirus) outbreak, enterprise VPN servers have now become paramount to a company's backbone, and their security and availability must be the focus going forward for IT teams.
It is critical that the VPN service is patched and up to date because there will be more scanning against these services.
It is also critical that multi factor authentication (MFA or 2FA) is used to protect connections over VPN.
What do you not want right now? A bunch of Cisco SD-WAN, Webex vulnerabilities? Here are a bunch of them
Cisco has issued a series of security updates for its SD-WAN and Webex software, just when they're most needed.
SD-WAN is host to five vulnerabilities ranging from privilege escalation to remote code injection.
Meanwhile, the Webex video-conferencing software also needs some sorting out right when everyone's working from home amid the coronavirus pandemic.
The patch bundle includes a fix for Cisco Webex Network Recording Player for Microsoft Windows and Cisco Webex Player for Microsoft Windows. A hacker can send a suitably crafted file in either the Advanced Recording Format (ARF) or the Webex Recording Format (WRF), and if the recipient clicks on it on a vulnerable computer, they get pwned. iOS users also need to patch an information-disclosure bug.
The other fixes mention SQL injection and cross-site scripting flaws.

Windows 10 or Mac user? Patch Adobe Reader and Acrobat now to fix 9 critical security flaws
Adobe has released an important security update for its popular PDF products, Adobe Acrobat and Reader after missing its usual release aligned with Microsoft Patch Tuesday.
The company has released an update for the PDF software for Windows and macOS machines. The update addresses nine critical flaws and four vulnerabilities rated as important.
The critical flaws include an out-of-bounds write, a stack-based overflow flaw, a use-after-free, buffer overflow, and memory corruption bug.
All the critical flaws allow for arbitrary code execution, meaning attackers could use them to rig a PDF to install malware on a computer running a vulnerable version of the software.
WordPress and Apache Struts account for 55% of all weaponized vulnerabilities
Comprehensive study looks at the most attacked web technologies of the last decade.
A study that analysed all the vulnerability disclosures between 2010 and 2019 found that around 55% of all the security bugs that have been weaponized and exploited in the wild were for two major application frameworks, namely WordPress and Apache Struts.
The Drupal content management system ranked third, followed by Ruby on Rails and Laravel, according to a report published this week.
In terms of programming languages, vulnerabilities in PHP and Java apps were the most weaponized bugs of the last decade.

Trickbot malware adds new feature to target telecoms, universities and finance companies
Researchers uncover a Trickbot campaign with new abilities that looks like it's being used in an effort to steal intellectual property, financial data - and potentially for espionage.
The new form of the infamous Trickbot malware is using never-before-seen behaviour in attacks targeting telecommunications providers, universities and financial services in a campaign that looks to be going after intellectual property and financial data.
Trickbot has been in operation since 2016 and, while it started life as a banking trojan, the modular nature of the malware means it can be easily re-purposed for other means, which has led to it becoming one of the most advanced and capable forms of malware attack delivery in the world today.
And now it has been updated with yet another new capability, with a module that uses brute force attacks against targets mostly in telecoms, education, and financial services in the US and Hong Kong. These targets are pre-selected based on IP addresses, indicating that the attackers are going after them specifically.
Most organizations have yet to fix CVE-2020-0688 Microsoft Exchange flaw
Organisations are delaying in patching Microsoft Exchange Server flaw (CVE-2020-0688) that Microsoft fixed with February 2020 Patch Day updates.
The CVE-2020-0688 flaw resides in the Exchange Control Panel (ECP) component, the root cause of the problem is that Exchange servers fail to properly create unique keys at install time.
A remote, authenticated attacker could exploit the CVE-2020-0688 vulnerability to execute arbitrary code with SYSTEM privileges on a server and take full control.

Two Trend Micro zero-days exploited in the wild by hackers
Hackers tried to exploit two zero-days in Trend Micro antivirus products, the company said in a security alert this week.
The Japanese antivirus maker has released patches on Monday to address the two zero-days, along with three other similarly critical issues (although, not exploited in the wild).
According to the alert, the two zero-days impact the company's Apex One and OfficeScan XG enterprise security products.
Trend Micro did not release any details about the attacks.
These two zero-days mark the second and third Trend Micro antivirus bugs exploited in the wild in the last year.

Most ransomware attacks take place during the night or over the weekend
27% of all ransomware attacks take place during the weekend, 49% after working hours during weekdays
The vast majority of ransomware attacks targeting the enterprise sector occur outside normal working hours, during the night or over the weekend.
According to a report published this week, 76% of all ransomware infections in the enterprise sector occur outside working hours, with 49% taking place during night-time over the weekdays, and 27% taking place over the weekend.
The numbers were compiled from dozens of ransomware incident response investigations from 2017 to 2019.
The reason why attackers are choosing to trigger the ransomware encryption process during the night or weekend is because most companies don't have IT staff working those shifts, and if they do, they are most likely short-handed.
If a ransomware attack does trigger a security alert within the company, then there would be nobody to react right away and shut down a network, or the short-handed staff would have a hard time figuring what's actually happening before the ransomware encryption process ends and the company's network is down & ransomed.
