Top Cyber Stories of the Last Week

61 Percent Of Employees Fail Basic Cyber Security Quiz

Nearly 70% of employees polled in a new survey said they recently received cyber security training from their employers, yet 61% nevertheless failed when asked to take a basic quiz on the topic. This was one of the leading findings of a research study that sought to understand the cyber security habits of some 1,200 workers, as well as their knowledge of best practices and ability to recognize security threats.

More Than 1,900 Distinct Hacking Groups Are Active Today

There are currently more than 1,900 distinct hacking groups that are active today, a number that grew from 1,800 groups recorded at the end of 2019. In its yearly cyber crime report, the company said it discovered 650 new threat actors during 2020, but new evidence also allowed it to remove 500 groups from its threat actor tracker due to overlaps in activity and hacking infrastructure with previously known clusters.

Ransomware: The Internet's Biggest Security Crisis Is Getting Worse

Organisations continue to fall victim to ransomware, and yet progress on tackling these attacks, which now constitute one of the biggest security problems on the internet, remains slow. From small companies to councils, government agencies and big business, the number and range of organisations hit by ransomware is rising. One recent example; schools with 36,000 students have been hit, leaving pupils without access to email as attempts were made to get systems back online. That is at least four chains of schools attacked in the last month.

Enterprise Security Attackers Are One Password Away From Your Worst Day

If the definition of insanity is doing the same thing over and over and expecting a different outcome, then one might say the cyber security industry is insane.

Criminals continue to innovate with highly sophisticated attack methods, but many security organisations still use the same technological approaches they did 10 years ago. The world has changed, but cyber security hasn’t kept pace.

Distributed systems, with people and data everywhere, mean the perimeter has disappeared. And the hackers couldn’t be more excited. The same technology approaches, like correlation rules, manual processes and reviewing alerts in isolation, do little more than remedy symptoms while hardly addressing the underlying problem.

Credentials are supposed to be the front gates of the castle, but as the SOC is failing to change, it is failing to detect. The cyber security industry must rethink its strategy to analyse how credentials are used and stop breaches before they become bigger problems.

Microsoft’s April Update Patches 114 Bugs—Half Of Which Allow Remote Code Execution

The fourth Patch Tuesday of 2021 is another big one. Today, Microsoft revealed 114 vulnerabilities fixed in the monthly security, over half of which could potentially be exploited for remote code execution by attackers. Of the 55 remote execution bugs, over half were tied to Windows’ Remote Procedure Call (RPC) interface. Four more were Microsoft Exchange bugs (all urgent fixes) reported to Microsoft by the National Security Agency. In addition, six Chrome vulnerabilities that were previously addressed by Google are included in the roll-up.

Nation-State Cyber Attacks Targeting Businesses Are On The Rise

Businesses are increasingly coming under fire from nation state-backed hackers as governments around the world engage in attacks to steal secrets or lay the foundations for future attacks. Nation States, Cyberconflict and the Web of Profit, a study by cyber security researchers at HP and criminologists at the University of Surrey, warns that the number of key nation-state attacks has risen significantly over the past three years – and that enterprises and businesses are increasingly being targeted. An analysis of nation-state cyber attacks between 2017 and 2020 reveals that just over a third of organisations targeted were businesses: cyber defence, media, government, and critical infrastructure are all also common targets in these attacks, but enterprise has risen to the top of the list.

Cyber Criminals Are Installing Cryptojacking Malware On Unpatched Microsoft Exchange Servers

Cyber criminals are targeting vulnerable Microsoft Exchange servers with cryptocurrency mining malware in a campaign designed to secretly use the processing power of compromised systems to make money. Zero-day vulnerabilities in Microsoft Exchange Server were detailed last month when Microsoft released critical security updates to prevent the exploitation of vulnerable systems. Cyber attackers ranging from nation-state-linked hacking groups to ransomware gangs have rushed to take advantage of unpatched Exchange servers -- but they are not the only ones.

NAME:WRECK DNS Vulnerabilities Affect Over 100 Million Devices

Security researchers have disclosed nine vulnerabilities affecting network communication stacks running on at least 100 million devices. Collectively referred to as NAME: WRECK, the flaws could be leveraged to take offline affected devices or to gain control over them. The vulnerabilities were found in a wide range of products, from high-performance servers and networking equipment to operational technology (OT) systems that monitor and control industrial equipment. According to researchers threat actors could exploit NAME:WRECK vulnerabilities to deal significant damage to government or enterprise servers, healthcare facilities, retailers, or companies in the manufacturing business by stealing sensitive data, modifying or taking equipment offline for sabotage purposes.

Brits Still Confused By Multi-Factor Authentication

The British public are still woefully underinformed and unaware of the security benefits of multi-factor authentication (MFA). The industry association, founded in 2012 to promote authentication standards and reduce global reliance on passwords, recently polled over 4000 consumers in the UK, France, Germany, and the US. It revealed that half (49%) UK consumers have had their social media accounts compromised or know a friend or family member who has. However, despite a continued number of high-profile account takeovers, 43% said this does not make them enhance security on their accounts, even though they “feel like” they should. Part of the problem seems to be a general lack of understanding about the benefits of MFA in protecting account holders from phishing, as well as credential stuffing and other brute force attack types. Although such features are offered by all social media companies today, over a quarter (26%) of respondents said they were not using or didn’t know about them.

623K Payment Cards Stolen From Cyber Crime Forum

The Swarmshop cyber underground “card shop” has been hit by hackers, who lifted the site’s database of stolen payment-card data and leaked it online. That is according to researchers, who said that the database was posted on a rival underground forum. Card shops, are online cyber criminal forums where stolen payment-card data is bought and sold. Researchers said the database in question contains 623,036 payment-card records from card-issuers in Brazil, Canada, China, France, Mexico, Saudi Arabia, Singapore, the U.K., and the U.S.

Top Cyber Stories of the Last Week

Ransomware Attacks Grew By 485% In 2020

Ransomware attacks increased by an astonishing 485% in 2020 compared to 2019, according to Bitdefender’s 2020 Consumer Threat Landscape Report, which highlighted the ways cyber criminals targeted the COVID-19 pandemic. Interestingly, nearly two-thirds (64%) of the ransomware attacks took place in the first two quarters of 2020.

Cyber Insurance Firm Suffers Sophisticated Ransomware Cyber Attack; Data Obtained May Help Hackers Better Target Firm’s Customers

One of the largest insurance firms in the US CNA Financial was reportedly hit by a “sophisticated cyber security attack” on March 21, 2021. The cyber attack disrupted the company’s employee and customer services for three days as the company shut down “out of an abundance of caution” to prevent further compromise.

Ransom Gangs Emailing Victim Customers For Leverage

Some of the top ransomware gangs are deploying a new pressure tactic to push more victim organisations into paying an extortion demand: Emailing the victim’s customers and partners directly, warning that their data will be leaked to the dark web unless they can convince the victim firm to pay up.

'We Have Your Porn Collection': The Rise Of Extortionware

Experts say the trend towards ransoming sensitive private information could affect companies not just operationally but through reputation damage. It comes as hackers bragged after discovering an IT Director's secret porn collection. The targeted US firm has not publicly acknowledged that it was hacked. In its darknet blog post about the hack last month, the cyber-criminal gang named the IT director whose work computer allegedly contained the files.

Should Firms Be More Worried About Firmware Cyber Attacks?

Microsoft recently put out a report claiming that businesses globally are neglecting a key aspect of their cyber security - the need to protect computers, servers, and other devices from firmware attacks. Its survey of 1,000 cyber security decision makers at enterprises across multiple industries in the UK, US, Germany, Japan, and China has revealed that 80% of firms have experienced at least one firmware attack in the past two years. Yet only 29% of security budgets have been allocated to protect firmware.

Armed Conflict Draws Closer As State-Backed Cyber Attacks Intensify

The world is coming perilously close to nation states retaliating against cyber attacks with conventional weapons, according to a new HP report. Publicly available reports into state-sponsored attacks and interviews with scores of experts. It claimed there has been a 100% increase in “significant” state-backed attacks between 2017-20, and an average of over 10 publicly attributed attacks per month in 2020 alone.

Coca-Cola Trade Secret Theft Underscores Importance Of Insider Threat Early Detection

The trial of Xiaorong You started in Greenville, TN, this week. She is accused of trade secret theft and economic espionage after allegedly stealing technologies owned by several companies, including her former employers Coca-Cola and Eastman Chemical Company. The value placed on the development of the stolen technologies is $119.6 million. Other affected companies include Azko-Nobel, Dow Chemical, PPG, TSI, Sherwin Williams and ToyoChem.

The details of the case suggest that the damages the accused is allegedly responsible for could have been minimized if better real-time insider threat detection methods had been in place. They also outline possible motives for the theft of the intellectual property: ego and money.

Attackers Blowing Up Discord, Slack With Malware

Workflow and collaboration tools like Slack and Discord have been infiltrated by threat actors, who are abusing their legitimate functions to evade security and deliver info-stealers, remote-access trojans (RATs) and other malware. The pandemic-induced shift to remote work drove business processes onto these collaboration platforms in 2020, and predictably, 2021 has ushered in a new level cyber criminal expertise in attacking them.

Scraped Data Of 500 Million LinkedIn Users Being Sold Online, 2 Million Records Leaked As Proof

An archive containing data purportedly scraped from 500 million LinkedIn profiles has been put for sale on a popular hacker forum, with another 2 million records leaked as a proof-of-concept sample by the post author. The four leaked files contain information about the LinkedIn users whose data has been allegedly scraped by the threat actor, including their full names, email addresses, phone numbers, workplace information, and more.

While users on the hacker forum can view the leaked samples for about $2 worth of forum credits, the threat actor appears to be auctioning the much-larger 500 million user database for at least a 4-digit sum, presumably in bitcoin.

Massive Facebook Data Breach Leaks Info On Millions Of Users

The personal information of hundreds of millions of Facebook users across the globe has been leaked online. Around 533 million Facebook users are thought to have been affected by the data breach, with phone numbers, Facebook ID, full name, location, past location, birthdate, email address, account creation date, relationship status, and personal bios all available. The data is thought to be the same set that was leaked in January 2021 and was available to purchase online, meaning Facebook has failed to secure its users once again.
