Top Cyber Stories of the Last Week

Cyber Crime Losses Triple To £1.3bn In H1 2021

Individuals and organisations lost three times more money to cyber crime and fraud in the first half of the year compared to the same period in 2020, as incidents soared, according to new figures. The report revealed that between January 1 and July 31 2020, victims lost £414.7m to cyber crime and fraud. However, the figure surged to £1.3bn for the same period in 2021. This can be partly explained by the huge increase in cases from last year to this. In the first half of 2020, there were just 39,160 reported to Action Fraud, versus 289,437 in the first six months of 2021. https://www.infosecurity-magazine.com/news/cybercrime-losses-triple-to-13bn/

Ransomware On A Rampage; A New Wake-Up Call

The ransomware rampage is continuing at pace and continues to create significant cyber security challenges. The use of ransomware by hackers to leverage exploits and extract financial benefits is not new. Ransomware has been around for over 2 decades, (early use of basic ransomware malware was used in the late 1980s) but as of late, it has become a trending and more dangerous cybersecurity threat. The inter-connectivity of digital commerce and expanding attack surfaces have enhanced the utility of ransomware as cyber weapon of choice for bad actors. Like bank robbers, cyber criminals go where the money is accessible. And it is now easier for them to reap benefits from extortion. Hackers can now demand cryptocurrencies payments or pre-paid cards that can be anonymously transacted. Those means of digital payments are difficult to trace by law enforcement. https://www.forbes.com/sites/chuckbrooks/2021/08/21/ransomware-on-a-rampage-a-new-wake-up-call/?sh=64a622362e81

22% Of Cyber Security Incidents In H1 2021 Were Ransomware Attacks

A report uncovered the number and nature of UK cyber security breaches reported to the UK Information Commissioner’s Office (ICO) in 2020 and 2021. So far in 2021 phishing was to blame for most incidents, accounting for 40% of all cyber security cases reported to the ICO, slightly down from 44% the year before. However, ransomware is surging, up from 11% of all reported incidents in the first half of 2020 to 22% in 2021. https://www.helpnetsecurity.com/2021/08/25/cybersecurity-incidents-h1-2021/

Ransomware: These Four Rising Gangs Could Be Your Next Major Cyber Security Threat

In recent months some significant ransomware operators have seemingly disappeared. But that doesn't mean that ransomware is any less of a problem, quite the opposite – new groups are emerging to fill the gaps and are often worse than the gangs that went before them. Cyber security researchers have detailed four upcoming families of ransomware discovered during investigations – and under the right circumstances, any of them could become the next big ransomware threat. One of these is LockBit 2.0, a ransomware-as-a-service operation that has existed since September 2019 but has gained major traction over the course of this summer. Those behind it revamped their dark web operations in June – when they launched the 2.0 version of LockBit – and aggressive advertising has drawn attention from cyber criminals. https://www.zdnet.com/article/ransomware-these-four-rising-threats-could-be-the-next-major-cybersecurity-risk-facing-your-business/

Key Email Threats And The High Cost Of Business Email Compromise

Researchers published the results of a study analysing over 31 million threats across multiple organisations and industries, with new findings and warnings issued by technical experts that every organisation should be aware of. A key aspect to preventing attacks is having a deep understanding of cyber actor patterns and continuously monitoring and deconstructing campaigns to anticipate future ones. Phishing can be a profitable business model, and most breaches begin with a phishing email. What appears to be an innocent email from a trusted vendor or internal department can lead to firm-wide shutdowns, loss of crucial data, and millions in financial costs. As detailed in the report, threats ranging from ransomware, credential harvesters to difficult-to-discover but costly Business Email Compromise (BEC) targeted inboxes, could have resulted in over $354 million in direct losses had they been successful. https://www.helpnetsecurity.com/2021/08/23/key-email-threats/

Microsoft Warns Thousands Of Cloud Customers Of Exposed Databases

Microsoft on Thursday warned thousands of its cloud computing customers, including some of the world's largest companies, that intruders could have the ability to read, change or even delete their main databases, according to a copy of the email and a cyber security researcher. The vulnerability is in Microsoft Azure's flagship Cosmos DB database. A research team at security a company discovered it was able to access keys that control access to databases held by thousands of companies. https://www.reuters.com/technology/exclusive-microsoft-warns-thousands-cloud-customers-exposed-databases-emails-2021-08-26/

58% Of IT Leaders Worried Their Business Could Become A Target Of Rising Nation State Attacks

Researchers released the findings of a global survey of 1,100 IT decision makers (ITDMs), examining their concerns around rising nation state attacks. 72% of respondents said they worry that nation state tools, techniques, and procedures (TTPs) could filter through to the dark net and be used to attack their business. https://www.helpnetsecurity.com/2021/08/23/rising-nation-state-attacks/

Cyber Insurance Market Encounters ‘Crisis Moment’ As Ransomware Costs Pile Up

It’s a sure sign of trouble when leading insurance industry executives are worried about their own prices going up. Ransomware now accounts for 75% of all cyber insurance claims, up from 55% in 2016, according to the credit ratings agency. The percentage increase in claims is outpacing that of premiums, said a June report which concluded that “the prospects for the cyber insurance market are grim.” Fitch Ratings in April found that the ratio of losses to premiums earned was at 73% last year, jeopardizing the profitability of the industry. https://www.cyberscoop.com/cyber-insurance-ransomware-crisis/

Security Teams Report Rise In Cyber Risk

Do you feel like you are gaining in your ability to protect your data and your network? If you are like 80% of respondents to the a recent report, you expect to experience a data breach that compromises customer data in the next 12 months. The report surveyed more than 3,600 businesses of all sizes and industries across North America, Europe, Asia-Pacific, and Latin America for their thoughts on cyber risk. Despite an increased focus on security due to high-profile ransomware and other attacks in the past year, respondents reported a rise in risk due to inadequate security processes like backing up key assets. https://www.csoonline.com/article/3629477/security-teams-report-rise-in-cyber-risk.html

WARNING: Microsoft Exchange Under Attack With ProxyShell Flaws

The U.S. Cyber security and Infrastructure Security Agency is warning of active exploitation attempts that leverage the latest line of "ProxyShell" Microsoft Exchange vulnerabilities that were patched earlier this May, including deploying LockFile ransomware on compromised systems. The vulnerabilities enable adversaries to bypass ACL controls, elevate privileges on the Exchange PowerShell backend, effectively permitting the attacker to perform unauthenticated, remote code execution. While the former two were addressed by Microsoft on April 13, a patch for CVE-2021-31207 was shipped as part of the Windows maker's May Patch Tuesday updates. https://thehackernews.com/2021/08/microsoft-exchange-under-attack-with.html

Top Cyber Stories of the Last Week

40% Fell Victim To A Phishing Attack In The Past Month

The global shift to remote work has exacerbated the onslaught, sophistication, and impact of phishing attacks, according to Ivanti. Nearly three-quarters (74%) of respondents said their organisations have fallen victim to a phishing attack in the last year, with 40% confirming they have experienced one in the last month.

Eighty percent of respondents said they have witnessed an increase in volume of phishing attempts and 85% said those attempts are getting more sophisticated. In fact, 73% of respondents said that their IT staff had been targeted by phishing attempts, and 47% of those attempts were successful.

Smishing and vishing scams are the latest variants to gain traction and target mobile users. According to recent research by Aberdeen, attackers have a higher success rate on mobile endpoints than on servers – a pattern that is trending dramatically worse. Meanwhile, the annualized risk of a data breach resulting from mobile phishing attacks has a median value of about $1.7M, and a long tail of value of about $90M.

https://www.helpnetsecurity.com/2021/07/23/risk-phishing-attacks/

Traditional Ransomware Defences Are Failing Businesses

Traditional cyber security strategies are failing to protect organisations from ransomware attacks, new research suggests. Based on a poll of 200 IT decision-makers whose businesses recently suffered ransomware attacks, 54 percent of all victims had their employees go through anti-phishing training. Furthermore, almost half (49 percent) had perimeter defences set up at the time of the attack. However, attack methods have grown too sophisticated for traditional security measures to keep up. Many attacks (24 percent) still start with a successful phishing attempt, while almost a third (31 percent) see attacker enter the network through public cloud.

Cyber Security Risk: The Number Of Employees Going Around IT Security May Surprise You

Last month, a report was published highlighting challenges associated with enabling IT freedoms while ensuring tight security procedures. The findings detail a complex balancing act between IT teams and network users. Calibrating this equilibrium is particularly challenging in the age of remote work as employees log on and virtually collaborate via a host of digital solutions. Overall, the survey found that virtually all employees (93%) "are working around IT restrictions," and a mere 7% said they were "satisfied with their corporate IT restrictions." Interestingly, this information about IT workarounds does not match security leaders' and IT expectations.

740 ransomware victims named on data leak sites in Q2 2021: report

More than 700 organizations were attacked with ransomware and had their data posted to data leak sites in Q2 of 2021, according to a new research report from cyber security firm Digital Shadows.

Out of the almost 2,600 victims listed on ransomware data leak sites, 740 of them were named in Q2 2021, representing a 47% increase compared to Q1.

https://www.zdnet.com/article/740-ransomware-victims-named-on-data-leak-sites-in-q2-2021-report/

A More Dynamic Approach Is Needed To Tackle Today’s Evolving Cyber Security Threats

For decades, the cyber security industry has followed a defense-in-depth strategy, which allowed organisations to designate the battlefield against bad actors at their edge firewall. Nowadays, cyber criminals have become as creative as ever. New cyber threats are emerging every day, and with the constantly increasing rate of Ransomware, Phishing, etc. We’re forced to take a more dynamic approach when tackling these cyber threats on a day to day basis. Recent statistics demonstrate the scale of the cyber security issues faced by companies. In 2020, malware attacks increased by 358% and ransomware increased by 435%, and the average cost of recovering from a ransomware attack has doubled in the last 12 months, reaching almost $2 million in 2021.

https://www.helpnetsecurity.com/2021/07/13/dynamic-approach-cybersecurity-threats/

Law Firm For Ford, Boeing, Exxon, Marriott, Walgreens, And More Hacked In Ransomware Attack

Campbell Conroy & O'Neil, P.C., a law firm handling hundreds of cases for the world's leading companies, has announced a large data breach that resulted from a ransomware attack in February.  In a statement, the law firm said it noticed unusual activity on its network on February 27. The firm later realized it was being hit with a ransomware attack and contacted the FBI as well as cyber security companies for help.

https://www.zdnet.com/article/law-firm-for-ford-boeing-exxon-marriott-walgreens-and-more-hacked-in-ransomware-attack/

UK And Allies Accuse China Of 'Reckless' Cyber Extortion And Microsoft Hack

The Government was hinting yet again at covertly using Britain’s own offensive cyber capabilities – hitting back at cyber attacks with cyber attacks of our own. This approach goes all the way back to 2013, when then defence secretary told the Conservative Party conference that the UK would “build a dedicated capability to counter-attack in cyber space and, if necessary, to strike in cyber space”.

https://www.telegraph.co.uk/world-news/2021/07/19/uk-allies-accuse-china-reckless-cyber-extortion-microsoft-hack/

Even after Emotet takedown, Office docs deliver 43% of all malware downloads now

Malware delivered over the cloud increased by 68% in Q2, according to data from cyber security firm Netskope.

The company released the fifth edition of its Cloud and Threat Report that covers the cloud data risks, threats and trends they see throughout the quarter.

The report noted that cloud storage apps account for more than 66% of cloud malware delivery.

"In Q2 2021, 43% of all malware downloads were malicious Office docs, compared to just 20% at the beginning of 2020. This increase comes even after the Emotet takedown, indicating that other groups observed the success of the Emotet crew and have adopted similar techniques," the report said.

Gun Owners' Fears After Firearms Dealer Data Breach

Thousands of names and addresses belonging to UK customers of a leading website for buying and selling shotguns and rifles have been published to the dark web following a "security breach".

Guntrader.uk told the BBC it learned of the breach on Monday and had notified the Information Commissioner's Office.

Police, including the National Crime Agency, are investigating.

One affected gun owner said he was afraid the breach could lead to his family being targeted by criminals.

Gun ownership is tightly controlled in the UK, making guns difficult to acquire, and potentially valuable on the black market.

The individual, who did not wish to be named, told the BBC the breach "seriously compromises my security arrangements for my firearms and puts me in a situation where me and my family could be targeted and in danger".

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.

https://www.scmagazine.com/home/security-news/61-percent-of-employees-fail-basic-cybersecurity-quiz/

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.

https://therecord.media/fireeye-more-than-1900-distinct-hacking-groups-are-active-today/

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.

https://www.zdnet.com/article/ransomware-the-internets-biggest-security-crisis-is-getting-worse-we-need-a-way-out/?&web_view=true

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.

https://techcrunch.com/2021/04/16/enterprise-security-attackers-are-one-password-away-from-your-worst-day/

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.

https://www.zdnet.com/article/free-money-cyber-criminals-are-installing-cryptojacking-malware-on-unpatched-microsoft-exchange-servers/

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.

https://www.bleepingcomputer.com/news/security/name-wreck-dns-vulnerabilities-affect-over-100-million-devices/

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.
