Cyber-Attacks on UK Organisations Up 30% in Q1 2020

New research has revealed that the volume of cyber-attacks on UK businesses increased by almost a third in the first three months of 2020.

Analysts identified 394,000 unique IP addresses used to attack UK businesses in the first quarter of 2020, discovering that companies with internet connections experienced 157,000 attacks each, on average – the equivalent of more than one a minute.

This rate of attack was 30% higher than the same period in 2019 when UK businesses received 120,000 internet-borne attempts to breach their systems each.

IoT applications were cited as the most common targets for cyber-criminals in the first quarter, attracting almost 19,000 online attacks per company. Company databases and file-sharing systems were also targeted frequently, with companies experiencing approximately 5000 attacks for each application, on average.

COVID-19 blamed for 238% surge in cyber attacks against banks

The coronavirus pandemic has been connected to a 238% surge in cyber attacks against banks, new research claims.

On Thursday, VMware Carbon Black released the third edition of the Modern Bank Heists report, which says that financial organizations experienced a massive uptick in cyber attack attempts between February and April this year -- the same months in which COVID-19 began to spread rapidly across the globe.

The cyber security firm's research, which includes input from 25 CIOS at major financial institutions, adds that 80% of firms surveyed have experienced more cyber attacks over the past 12 months, an increase of 13% year-over-year.

VMware Carbon Black data already indicates that close to a third -- 27% -- of all cyber attacks target either banks or the healthcare sector.

An interesting point in the report is how there appears to have been an uptick in financially-motivated attacks around pinnacles in the news cycle, such as when the US confirmed its first case of COVID-19.

In total, 82% of chief information officers contributing to the report said that alongside a spike in attacks, techniques also appear to be improving -- including the use of social engineering and more advanced tactics to exploit not only the human factor but also weak links caused by processes and technologies in use by the supply chain.

May 2020 Patch Tuesday: Microsoft fixes 111 vulnerabilities, 13 Critical

Microsoft's May 2020 Patch Tuesday fell this week, and Microsoft have released fixes for 111 vulnerabilities in Microsoft products. Of these vulnerabilities, 13 are classified as Critical, 91 as Important, 3 as Moderate, and 4 as Low.

This month there are no zero-day or unpatched vulnerabilities.

Users should install these security updates as soon as possible to protect Windows from known security risks.

Adobe issues patches for 36 vulnerabilities in DNG, Reader, Acrobat

Adobe has released security patches to resolve 36 vulnerabilities present in DNG, Reader, and Acrobat software.

On Tuesday, the software giant issued two security advisories (1, 2) detailing the bugs, the worst of which can be exploited by attackers to trigger remote code execution attacks and information leaks.

The first set of patches relate to Adobe Acrobat and Reader for Windows and macOS, including Acrobat / Acrobat Reader versions 2015 and 2017, as well as Acrobat and Acrobat Reader DC.

In total, 12 critical security flaws have been resolved. Six of the bugs, a single heap overflow problem, two out-of-bounds write errors, two buffer overflow issues, and two use-after-free vulnerabilities can all lead to arbitrary code execution in the context of the current user.

Thunderbolt flaw ‘Thunderspy’ allows access to a PC’s data in minutes

Vulnerabilities discovered in the Thunderbolt connection standard could allow hackers to access the contents of a locked laptop’s hard drive within minutes, a security researcher from the Eindhoven University of Technology has announced. Reports state that the vulnerabilities affect all Thunderbolt-enabled PCs manufactured before 2019.

Although hackers need physical access to a Windows or Linux computer to exploit the flaws, they could theoretically gain access to all data in about five minutes even if the laptop is locked, password protected, and has an encrypted hard drive. The entire process can reportedly be completed with a series of off-the-shelf components costing just a few hundred dollars. Perhaps most worryingly, the researcher says the flaws cannot be patched in software, and that a hardware redesign will be needed to completely fix the issues.

A hacker group is selling more than 73 million user records on the dark web

A hacker group going by the name of ShinyHunters claims to have breached ten companies and is currently selling their respective user databases on a dark web marketplace for illegal products.

The hackers are the same group who breached last week Tokopedia, Indonesia's largest online store. Hackers initially leaked 15 million user records online, for free, but later put the company's entire database of 91 million user records on sale for $5,000.

Encouraged and emboldened by the profits from the Tokopedia sale, the same group has, over the course of the current week, listed the databases of 10 more companies.

This includes user databases allegedly stolen from organizations such as:

· Online dating app Zoosk (30 million user records)

· Printing service Chatbooks (15 million user records)

· South Korean fashion platform SocialShare (6 million user records)

· Food delivery service Home Chef (8 million user records)

· Online marketplace Minted (5 million user records)

· Online newspaper Chronicle of Higher Education (3 million user records)

· South Korean furniture magazine GGuMim (2 million user records)

· Health magazine Mindful (2 million user records)

· Indonesia online store Bhinneka (1.2 million user records)

· US newspaper StarTribune (1 million user records)

The listed databases total for 73.2 million user records, which the hacker is selling for around $18,000, with each database sold separately.

A cybercrime store is selling access to more than 43,000 hacked servers

MagBo, a shadowy online marketplace where hackers sell and buy hacked servers, is doing better than ever and has soared in popularity to become the largest criminal marketplace of its kind since its launch in the summer of 2018.

Two years later, the MagBo portal has grown more than 14 times in size and is currently selling access to more than 43,000 hacked websites, up from the 3,000 sites listed in September 2018.

Today, MagBo has become the de-facto go-to marketplace for many cybercrime operations. Some groups register on the MagBo platform to sell hacked servers, while others are there just to buy.

Those who buy, do it either in bulk (for black-hat SEO or for malware distribution) or selectively, for intrusions at high-value target (e-commerce stores for web skimming, intranets for ransomware).

All in all, the MagBo platform cannot be ignored anymore, as it appears to be here to stay, and is placing itself at the heart of many of today's cybercrime operations.

Ransomware: Why paying the crooks can actually cost you more in the long run

Ransomware is so dangerous because in many cases the victim doesn't feel like they have any other option other than to pay up – especially if the alternative is the whole organisation being out of operation for weeks, or even months, as it attempts to rebuild the network from scratch.

But handing over a bitcoin ransom to cyber criminals can actually double the cost of recovery according to analysis by researchers at Sophos, published in the new State of Ransomware 2020 report, which has been released three years to the day from the start of the global WannaCry ransomware outbreak.

A survey of organisations affected by ransomware attacks found that the average total cost of a ransomware attack for organisations that paid the ransom is almost $1.4m, while for those who didn't give into ransom demands, the average cost is half of that, coming in at $732,000.

Often, this is because retrieving the encryption key from the attackers isn't a simple fix for the mess they created, meaning that not only does the organisation pay out a ransom, they also have additional costs around restoring the network when some portions of it are still locked down after the cyber criminals have taken their money.

According to the report, one in four organisations said they paid the ransom in order to get their files back. It's one of the key reasons why ransomware remains a successful tactic for crooks, because victims pay up – often sums of six-figures or more – and are therefore encouraging cyber criminals to continue with attacks that often can't be traced back to a culprit.

This powerful Android malware stayed hidden for years, infecting tens of thousands of smartphones

A carefully managed hacking and espionage campaign is infecting smartphones with a potent form of Android malware, providing those behind it with total control of the device, while also remaining completely hidden from the user.

Mandrake spyware abuses legitimate Android functions to help gain access to everything on the compromised device in attacks that can gather almost any information about the user.

The attacker can browse and collect all data on the device, steal account credentials for accounts including banking applications. secretly take recordings of activity on the screen, track the GPS location of the user and more, all while continuously covering their tracks.

The full capabilities of Mandrake – which has been observed targeting users across Europe and the Americas – are detailed in a paper released by cybersecurity researchers this week. Mandrake has been active since 2016 and researchers previously detailed how the spyware operation was specifically targeting Australian users – but now it's targeting victims around the world.

Companies wrestle with growing cyber security threat: their own employees

Businesses deploy analytic tools to monitor staff as remote working increases data breach risk

As cyber criminals and hackers ramp up their attacks on businesses amid coronavirus-related disruption, companies are also facing another equally grave security threat: their own employees.

Companies are increasingly turning to Big Brother-style surveillance tools to stop staff from leaking or stealing sensitive data, as millions work away from the watchful eyes of their bosses and waves of job cuts leave some workers disgruntled.

In particular, a brisk market has sprung up for cyber security groups that wield machine learning and analytics to crunch data on employees’ activity and proactively flag worrying behaviours.

Cognizant: Ransomware Costs Could Reach $70m

IT services giant Cognizant has admitted that a ransomware attack it suffered back in April may end up costing the company as much as $70m.

The firm announced revenue of $4.2bn for the first quarter of 2020, an increase of 2.8% year-on-year. In this context, the $50-70m hit it expects to take in Q2 from the ransomware attack will not make a huge impact on the company.

However, the big numbers involved are illustrative of the persistent financial threat posed by ransomware, not to mention the reputational impact on customers.

The firm claimed on an earnings call that the company responded immediately to the threat, proactively taking systems offline after some internal assets were compromised. However, the resulting downtime and suspension of some customer accounts took their toll financially.

“Some clients opted to suspend our access to their networks,” they explained. “Billing was therefore impacted for a period of time, yet the cost of staffing these projects remained on our books.”

Remote workers were also affected as the attack hit the firm’s system for supporting its distributed workforce during the current pandemic.

Package delivery giant Pitney Bowes confirms second ransomware attack in 7 months

Package and mail delivery giant Pitney Bowes has suffered a second ransomware attack in the past seven months, ZDNet has learned.

The incident came to light earlier in the week after a ransomware gang known as Maze published a blog post claiming to have breached and encrypted the company's network.

The Maze crew provided proof of access in the form of 11 screenshots portraying directory listings from inside the company's computer network.

Pitney Bowes confirmed the incident stating they had detected a security incident related to Maze ransomware.

The company said it worked with third-party security consultants to take steps to stop the attack before any of its data was encrypted.

This is the second ransomware incident for Pitney Bowes in seven months.

In October 2019, Pitney Bowes disclosed a first ransomware attack. At the time, the company said it had some critical systems infected and encrypted by the Ryuk ransomware gang. The incident caused limited downtime to some package tracking systems.

Both the Ryuk and Maze ransomware gangs are what experts call "human-operated" ransomware strains. These types of ransomware infections take place after hackers breach a company's network, and take manual control of the malware to expand access to as many internal systems as possible before executing the actual ransomware to encrypt data and demand a ransom.

Law Firm Representing Drake, Lady Gaga, Madonna And More Hit By Cyber Attack As Hackers Claim To Have Stolen Personal Information And Contracts

A law firm representing many of the world's most famous celebrities has been hacked.

The website of Grubman Shire Meiselas & Sacks has been taken offline, and hackers claim to have stolen some 756GB of data relating to its clients.

Singers, actors and other stars have worked with the law firm, according to old versions of its website, with more than 200 very high-profile celebrities and companies said to have used its services.

They include Madonna, Lady Gaga, Elton John and Drake.

The hackers behind the attack claim to have person information on celebrities including letters, as well as official contracts.

Hackers have already released a purported screenshot of a Madonna contract in an attempt to prove they have access to personal files.

It is not known what the hackers are demanding in return for the files, or whether negotiations are ongoing.

"We can confirm that we've been victimised by a cyber-attack," the firm said in a media statement. "We have notified our clients and our staff.

"We have hired the world's experts who specialise in this area, and we are working around the clock to address these matters."

The hack used a piece of software known as REvil or Sodinokibi. Similar software took foreign exchange company Travelex offline in January, as part of a major hack.

Traditionally, such ransomware has been used to lock down computers and demand money from their owners to unlock them again, and grant access to files.

Increasingly, hackers threaten to release those files to the public if their demands are not met.

Lights stay on despite cyber-attack on UK's electricity system

Britain’s energy system has fallen victim to a cyber-attack targeting the IT infrastructure used to run the electricity market.

The electricity system’s administrator, Elexon, confirmed that it was affected by a cyber-attack on Thursday afternoon but that the key systems used to govern the electricity market were not affected.

National Grid is investigating whether the attack could affect the part of its business tasked with keeping the lights on.

A spokesman for the energy system operator said electricity supplies had not been affected, and there were “robust cybersecurity measures in place” to make sure the UK continues to receive reliable electricity.

“We’re aware of a cyber intrusion on Elexon’s internal IT systems. We’re investigating the matter and any potential impact on our own IT networks,” he said.

Elexon is a vital part of the UK electricity market because it carefully monitors the electricity generated by energy companies to match this with what National Grid expects to receive, and to make sure that generators are paid the correct amount for the energy they generate.
