Top Cyber Stories of the Last Week
Russian Hackers Target IT Supply Chain In Ransomware Attack Leading To Hundreds Of Firms Being Hit
Hackers began a ransomware attack on Friday, hitting at least 200 companies, according to cyber security researchers.
In what appears to be one of the largest supply chain attacks to date, hackers compromised Kaseya, an IT management software supplier, in order to spread ransomware to the managed service providers that use its technology, as well as to their clients in turn.
The attacks have been attributed t=to REvil, the notorious Russia-linked ransomware cartel that the FBI claimed was behind recent crippling attack on beef supplier JBS.
The attack is the latest example of hackers weaponising the IT supply chain in order to attack victims at scale, by breaching just one provider. Last year, it emerged that Russian state-backed hackers had hijacked the SolarWinds IT software group in order to penetrate the email networks of US federal agencies and corporations, for example.
Late on Friday, Kaseya urged those using the compromised “VSA server” tool, which provides remote monitoring and patching capabilities, to shut it down immediately.

71% Of Organisations Experienced BEC Attacks Over The Past Year
Business email compromise (BEC) attacks are one of the most financially damaging cyber crimes and have been on the rise over the past year. This is according to a new report which revealed that spoofed email accounts or websites accounted for the highest number of BEC attack as 71% of organisations acknowledged they had seen one over the past year. This is followed by spear phishing (69%) and malware (24%). Data from 270 IT and cyber security professionals were collected to identify the latest enterprise adoption trends, gaps and solution preferences related to phishing attacks.

Cyber Insurance Isn't Helping With Cyber Security, And It Might Be Making The Ransomware Crisis Worse, Say Researchers
Cyber insurance is designed to protect organisations against the fallout of cyber attacks, including covering the financial costs of dealing with incidents. However, some critics argue that insurance encourages ransomware victims to simply pay the ransom demand that will then be covered by the insurers, rather than have adequate security to deter hackers in the first place. Insurers argue that it's the customer that makes any decision to pay the ransom, not the insurer.
LinkedIn Breach Reportedly Exposes Data Of 92% Of Users, Including Inferred Salaries
A second massive LinkedIn breach reportedly exposes the data of 700M users, which is more than 92% of the total 756M users. The database is for sale on the dark web, with records including phone numbers, physical addresses, geolocation data, and inferred salaries. The hacker who obtained the data has posted a sample of 1M records, and checks confirm that the data is both genuine and up to date. No passwords are included, but as the site notes, this is still valuable data that can be used for identity theft and convincing-looking phishing attempts that can themselves be used to obtain login credentials for LinkedIn and other sites. https://9to5mac.com/2021/06/29/linkedin-breach/
Users Clueless About Cyber Security Risks
Organisations are facing yet another unprecedented threat to their cyber security now that employees are headed back into offices with their personal devices, lax security hygiene and no clue about some of the most catastrophic attacks in history, such as the Colonial Pipeline shutdown. A new survey shows the mountains of work ahead for security teams in not just locking down their organisations’ systems but also in keeping users from getting duped into handing over the keys to the kingdom. 2,000 end users were surveyed in the U.S. and found the dangers to critical infrastructure, utilities and food supplies are not sinking in with the public, despite the deluge of headlines.

Ransomware: Paying Up Won't Stop You From Getting Hit Again, Says Cyber Security Chief
Ireland's Health Service Executive (HSE) has been praised for its response after falling victim to a major ransomware attack and for not giving into cyber criminals and paying a ransom. HSE was hit with Conti ransomware in May, significantly impacting frontline health services. The attackers initially demanded a ransom of $20 million in bitcoin for the decryption key to restore the network. While the gang eventually handed over a decryption key without receiving a ransom, they still published stolen patient data – a common technique by ransomware attackers, designed to pressure victims into paying.
Don’t Leave Your Cyber IR Plan To IT, It’s An Organisational Risk
Phishing attacks, insider threats, denial of service disruptions, malware and ransomware — cyber security incidents like these happen on a daily basis. For most of these incidents, the onsite IT team will remediate based on a pre-developed plan and process. And for many of these incidents, that’s a solid approach. But those incident response plans and strategies are IT oriented and geared toward short-term fixes and single incident responses. Meaning, if an incident accelerates beyond a handful of infected laptops or a compromised server and begins to affect operations of all or even part of the organisation, business itself can be disrupted — or even shut down entirely.

Cyber Crime Never Sleeps
When the Colonial Pipeline fell victim to a ransomware attack, people across the United States were shocked to find that a single episode of cyber crime could lead to widespread delays, gas shortages and soaring prices at the pump. But disruptive ransomware attacks like these are far from rare; in fact, they are becoming more and more frequent. Cyber crime is on the rise, and our cyber security infrastructure desperately needs to keep up. A quick look at the data from the last year confirms that cyber crime is a growing threat. Identity theft doubled in 2020 over 2019.

IT, Healthcare And Manufacturing Facing Most Phishing Attacks
Researchers examined more than 905 million emails for the H1 2021 Global Phish Cyber Attack Report, finding that the IT industry specifically saw 9,000 phishing emails in a one month span out of almost 400,000 total emails. Their healthcare industry customers saw more than 6,000 phishing emails in one month out of an average of over 450,000 emails and manufacturing saw a bit less than 6,000 phishing emails out of about 330,000 total emails. Researchers said these industries are ripe targets because of the massive amount of personal data they collect and because they are often stocked with outdated technology that can be easily attacked.

Classified Ministry Of Defence Documents Found At Bus Stop
Classified Ministry of Defence documents containing details about HMS Defender and the British military have been found at a bus stop in Kent. One set of documents discusses the likely Russian reaction to the ship's passage through Ukrainian waters off the Crimea coast on Wednesday. Another details plans for a possible UK military presence in Afghanistan after the US-led NATO operation there ends. The government said an investigation had been launched.
Cabinet Office Increases Cyber Security Training Budget By Almost 500%
The UK’s Cabinet Office increased its cyber security training budget to £274,142.85 in the fiscal year 2021 – a 483% increase from the £47,018 spent in the previous year. In its FOI response, the Cabinet Office detailed the cyber security courses attended by its staff, revealing that the number of booked courses grew from 35 in 2019-20 to 428 in the current fiscal year.

Ransomware accounted for 41% of all cyber insurance claims in H1 2020
Ransomware incidents have accounted for 41% of cyber insurance claims filed in the first half of 2020, according to a report published today by one of the largest providers of cyber insurance services in North America.
The high number of claims comes to confirm previous reports from multiple cyber-security firms that ransomware is one of today's most prevalent and destructive threats.
Ransomware doesn't discriminate by industry. An increase in ransom attacks has been seen across almost every industry.
In the first half of 2020 alone, they observed a 260% increase in the frequency of ransomware attacks amongst their policyholders, with the average ransom demand increasing 47%.
Among the most aggressive gangs, the cyber insurer listed Maze and DoppelPaymer, which have recently begun exfiltrating data from hacked networks, and threatening to release data on specialized leak sites, as part of double extortion schemes.
Why this matters:
Ransomware remains, and is likely to remain, by far one of the biggest menaces on the web, it is indiscriminate, anyone can be affected, it can be business destroying, and it is getting worse all the time.

Microsoft’s Patch Tuesday Packed with Critical RCE Bugs
Microsoft has released patches for 129 security bugs in its September Patch Tuesday update. These include 23 critical flaws, 105 that are important in severity and one moderate bug. Fortunately, none are publicly known or under active exploitation, Microsoft said.
The most severe issue in the bunch is CVE-2020-16875, according to researchers. This is a memory-corruption problem in Microsoft Exchange that allows remote code-execution (RCE) just by sending an email to a target. Running arbitrary code could grant attackers the access they need to create new accounts, access, modify or remove data, and install programs.
Why this matters:
Many organisations are struggling to keep up with the volume of updates and keeping on top of them, or knowing which to prioritise, is critical for firms. At a time while many organisations continue to struggle to support the ongoing distribution of remote workers, Microsoft continues to pile on the updates and finding an efficient method for rolling out these patches has become even more imperative as companies begin to abandon the idea of a short-term fix and shift operations to embrace remote work as part of a lasting, long-term progression of how organisations operate moving forward.
Firms are beginning to realise the negative outcomes of the lenient security measures put in place to quickly adapt to a decentralised workforce and it’s become more important than ever to establish patching policies that can securely support remote endpoints for the foreseeable future.

60 percent of emails in May and June were fraudulent
The COVID-19 pandemic has seen a spike in scams, phishing and malware across all platforms and attack vectors. The latest mid-year threat landscape report from Bitdefender shows that in May and June, an average of 60 percent of all received emails were fraudulent.
In addition there’s been a five-fold increase in the number of coronavirus-themed attacks and a 46 percent increase in attacks aimed at home IoT devices.
IoT malware has become versatile, robust, and is constantly updated. IrcFlu, Dark_Nexus7 and InterPLanetary Storm are some of the examples malware that gained in popularity during the first half of 2020.
Mobile malware has been quick to capitalise too, with malware developers rushing to weaponise popular applications, such as the Zoom video conferencing application, used by employees now working from home. Packing RAT (Remote Access Trojan) capabilities, or bundling them with ransomware, banking malware, or even highly aggressive adware, Android malware developers were also fully exploiting the pandemic wave.
Why this matters:
As we keep saying malicious actors never let a good crisis or tragedy go to waste and will exploit whatever is going on in the world or anything there is a collective interest in to real in unsuspecting victims.
Good awareness and education are key in keeping your employees and users safe and ensuring users at all levels, including board members – who present a significant risk, are up to date with latest tactics and threats.
Email in particular will remain primary vector for attack and this is unlikely to change any time soon.

Businesses [should] Fear Insider-Enabled Data Breaches
Businesses fear suffering a data breach and expect it to be caused by an insider or internal error.
A survey of 500 IT professionals found that 94% of respondents have experienced a data breach, and 79% were worried their organisation could be next.
The fear associated with breaches stems from the security culture within the organisation, along with the security reporting structure.
Having security teams in close dialogue with executive leadership, supporting the leadership to make informed risk-based decisions and driving the business strategy, including the technologies used, reduces this fear significantly.
Secondly, not understanding information security, its components and principles drives fear and anxiety of the unknown, so having security education training, and developing awareness and consciousness of threats, will enable and empower the entire organisation to act with a ‘security first’ mindset.
Finally, recognising the importance of access control to protect systems and data is a foundational level control that organisations can apply to reduce the risk of a data breach. Hand in hand with this is partnering with trusted identity and access control platform providers who can provide enterprises with that security expertise and industry leadership.
Why this matters:
In terms of what is causing the breaches, 40% of respondents to the survey said accidental employee incidents were to blame, compared to 21% who said it is external attackers. Asked if this is a case of businesses not having a handle on what leaves their organisations (either intentionally or accidentally), insiders already have access and can leave with data invisibly, which might turn up somewhere embarrassing later.

4 top vulnerabilities ransomware attackers exploited in 2020
As more employees work from home, attackers have more endpoints to target. These unpatched vulnerabilities in remote access tools and Windows makes their job easier.
The biggest security trend for 2020 has been the increase of COVID-19-related phishing and other attacks targeting remote workers. New York City, for example, has gone from having to protect 80,000 endpoints to around 750,000 endpoints in its threat management since work-from-home edicts took place.
As noted in a recent Check Point Software Technologies mid-year review, “The first impact of the pandemic was the proliferation of malware attacks that used social engineering techniques with COVID-19 thematic lures for the delivery stage.” Domain names were set up and parked with names relating to the pandemic. As workers started to use videoconferencing platforms, attacks moved to attacking Zoom, Teams and other videoconferencing platforms.
One disturbing trend is that 80% of the observed attacks in the first half of 2020 used vulnerabilities reported and registered in 2017 and earlier, according to the Check Point report, and more than 20% of the attacks used vulnerabilities that are at least seven years old. This showcases that we have a problem in keeping our software up to date.
Why this matters:
Ransomware remains a big threat 2020 and expanding attack surfaces with staff working from home is making the situation worse. Attackers use vulnerabilities in tools used for remote access into Windows networks.
Click read more below to find out the top four vulnerabilities the researchers identified.
APT Groups Increasingly Targeting Linux-Based Devices
APT groups are increasingly executing targeted attacks against Linux-based devices as well as developing more Linux-focused tools, according to an investigation by Kaspersky.
This is as a result of a growing number of organisations’ selecting Linux ahead of Windows to run their strategically important servers and systems, and the perception that the Linux operating system is safer and less likely to be targeted by malware as it is less popular.
However, threat-actors have been observed to adapt their tactics to take advantage of this trend, and Kaspersky noted that “over a dozen APT actors have been observed to use Linux malware or some Linux-based modules” during the past eight years.
These include notorious groups such as Turla, Lazarus, Barium, Sofacy, the Lamberts and Equation. Kaspersky highlighted the example of Russian speaking APT group Turla using Linux backdoors as part of its changing toolset in recent years.
Why this matters:
Attacks that target Linux-based systems are still fewer in number than attacks on Windows based systems, but there is still malware designed to target them, including webshells, backdoors, rootkits and even custom-made exploits.

Major Chilean bank shuts down all branches following ransomware attack
Banco Estado, the only public bank in Chile and one of the three largest in the country, had to shut down its nationwide operations on Monday due to a cyberattack that turned out to be a ransomware launched by REvil.
According to a public statement, the branches will remain closed for at least one day, but clarified that customers’ funds have not been affected by the incident.
Sources close to the investigation reported that the REvil ransomware gang is behind the attack. It reportedly originated from an Office document infected with the malware that an employee received and proceeded to open.
The incident was reported to the Chilean authorities, who issued a cyber-security alert that warned about a massive ransomware campaign targeting the private sector in the country.
Why this matters:
As above ransomware is not going away and is getting worse all the time. Too many users don’t realise that simply opening a document or clicking on a link in an email could bring down their entire organisations. Staff and users need to be educated about the role they play in securing their organisations.
Vulnerabilities discovered in PAN-OS, which powers Palo Alto Networks’ firewalls
Palo Alto Networks this week remediated vulnerabilities in PAN-OS (operating systems version 8.1 or later) which command injection, cross site scripting and the ability to upload unauhtoised files to a directory which might lead to denial of service.
Why this matters:
Attackers can use these vulnerabilities to gain access to sensitive data or develop the attack to gain access to the internal segments of the network of a company that uses vulnerable protection tools.
Any security fixes for known vulnerabilities across any different product, software or firmware should be tested and applied as soon as possible, so those vulnerabilities cannot be used against you or your organisation.

Russia, China and Iran hackers target Trump and Biden, Microsoft says
Hackers with ties to Russia, China and Iran are attempting to snoop on people and groups involved with the US 2020 presidential election, Microsoft says.
The Russian hackers who breached the 2016 Democratic campaign are again involved, said the US tech firm.
Microsoft said it was "clear that foreign activity groups have stepped up their efforts" targeting the election.
Both President Donald Trump and Democrat Joe Biden's campaigns are in the cyber-raiders' sights.
Russian hackers from the Strontium group have targeted more than 200 organisations, many of which are linked to US political parties - both Republicans and Democrats, Microsoft said in a statement.
Why this matters:
The same attackers have also targeted British political parties, said Microsoft, without specifying which ones. Any meddling in politics by foreign states is a clear threat to the democratic process and shows that unfriendly states will interfere to further their own agendas.

TikTok battles to remove video of livestreamed suicide
TikTok is battling to remove a graphic video of a livestreamed suicide, after the footage was uploaded to the service on Sunday night from Facebook, where it was initially broadcast.
Although the footage was rapidly taken down from TikTok, users spent much of Monday re-uploading it, initially unchanged, but later incorporated into so-called bait-and-switch videos, which are designed to shock and upset unsuspecting users.
One such video, for instance, begins with a conventional video of an influencer talking to camera, before cutting without warning to the graphic footage.
Why this matters:
Parents, especially of younger children, may think that certain sites and social media channels are safe for children and the content is suitable vetted and controlled, but as this illustrates that is often not the case and caution should be exercised in allow young children unfettered access to social media.
