Top Cyber Stories of the Last Week

500 Million Attempted Ransomware Attacks (So Far) in 2021, With No Sign Of Slowing

So far, 2021 is stacking up to be the most costly and dangerous year on record for the volume of ransomware attacks, SonicWall said in a new report.

The security provider has logged nearly 500 million attempted ransomware attacks through September, 2021, with 1,748 attempts per customer in that nine-month period. The overall total of 495 million to date amounts to a 148 percent surge as compared to the same period last year. SonicWall expects to record 714 million attempted ransomware attacks by the close of 2021, a 134 percent skyrocket over last year’s totals. https://www.msspalert.com/cybersecurity-research/500-million-attempted-ransomware-attacks-so-far-in-2021/

Top 10 Ways Attackers Are Increasing Pressure On Their Ransomware Victims To Pay

Sophos researchers have detailed how ransomware attackers are implementing a wide range of ruthless pressure tactics to persuade victims to pay the ransom.

Their research is based on evidence and insight from a team of 24/7 incident responders who help organisations under active cyberattack. It highlights the shift in ransomware pressure techniques from solely encrypting data to including other pain points, such as harassing employees.

Since organisations have become better at backing up their data and restoring encrypted files from backups, attackers are supplementing their ransom demands with additional extortion measures that increase the pressure to pay.

For example, the Sophos Rapid Response team has seen cases where attackers email or phone a victim’s employees, calling them by their name and sharing personal details they’ve stolen – such as any disciplinary actions or passport information – with the aim of scaring them into demanding their employer pays the ransom. This kind of behavior shows how ransomware has shifted from a purely technical attack targeting systems and data into one that also targets people. https://www.helpnetsecurity.com/2021/11/04/attackers-pressure-ransomware-victims/

40% Of Organisations Suffered A Cloud-Based Data Breach In The Past 12 Months

Despite increasing cyber attacks targeting data in the cloud, 83% of businesses are still failing to encrypt half of the sensitive data they store in the cloud, raising even greater concerns as to the impact cyber criminals can have. 40% of organisations have experienced a cloud-based data breach in the past 12 months, according to a study conducted by 451 Research.

Cloud adoption is on the rise and businesses are continuing to diversify the way they use cloud solutions. Globally, 57% of respondents reported they make use of two or more cloud infrastructure providers, whilst 24% of organisations flagged that the majority of their workloads and data now reside in the cloud. https://www.helpnetsecurity.com/2021/11/02/experienced-cloud-based-data-breach/

Midsize Business Cyber Attacks: A Security Reality Check

Ransomware bombshells hit large enterprises. Carpet-bomb cyberattacks target MSP software supply chains and their small business customers. But what’s the state of cybersecurity among midsize businesses?

Actually, that landscape also faces its share of digital bombshells. Indeed, nearly two in three midsize organisations have suffered a ransomware attack in the past 18 months and 20 percent of them spent at least $250,000 to recover from it, according to research by UncommonX, an MSSP that leans heavily on its own SaaS-based solutions..

The Chicago-based MSSP’s newly released State of Cybersecurity for Midsize Organisations found that smaller companies are often not properly prepared to fend off a cyber attack nor do they engage in adequate network monitoring. In short, cybersecurity is often not enough of a priority within midsize companies. https://www.msspalert.com/cybersecurity-news/midsize-business-cyberattacks-a-security-reality-check/

70% Of Dev Teams Admit To Skipping Security Steps

According to a new study by Invicti Security, 70% of development teams always or frequently skip security steps due to time pressures when completing projects. This explains why, in the average organisation, 33% of security issues in remediation at any given time come from production code.

Security and development teams spend every day inside a catch-22: relentless demand for continued digital innovation amid increasing security threats to a sprawling attack surface. While there are some bright spots emerging on the road to secure innovation, these professionals are stressed — and too often make bad choices. https://venturebeat.com/2021/10/27/report-70-of-dev-teams-admit-to-skipping-security-steps/

79% Of IT Teams Have Seen Increase In Endpoint Security Breaches

According to a new report by HP Wolf Security, 79% of IT teams have seen an increase in rebuild rates, indicating that hackers are becoming more successful at breaching the endpoint and compromising organisations’ devices and data.

This sudden increase in rebuild rates is particularly affecting enterprises with 1,000 employees or more — organisations of this kind have the highest average number of rebuilds per month at 67.3. The study also highlights that employees are clicking on more malicious emails. Whether this is because people are less vigilant working from home or because they find it harder to determine what is safe to open, the rising number of rebuilds suggests that hackers have become more successful at breaching the endpoint through malicious links. https://venturebeat.com/2021/10/28/report-79-of-it-teams-have-seen-increase-in-endpoint-security-breaches/

Enterprises With Subsidiaries More Prone To Cyber Attacks, Study Says

Global enterprises with multiple subsidiaries are more exposed to cybersecurity threats and have more difficulty managing risk than companies with no, or fewer, subsidiaries, according to an Osterman Research report commissioned by CyCognito.

The study surveyed 201 organisations with at least 10 subsidiaries and at least 3,000 employees or $1 billion in annual revenue.

Despite being extremely confident about running effective subsidiary risk management, about 67% of respondents said their organisations had either experienced a cyberattack where the attack chain included a subsidiary, or that they lacked the ability or information to rule out the possibility.

About half of the respondents acknowledged that they wouldn't be surprised if a cyberbreach were to occur "tomorrow." https://www.csoonline.com/article/3639014/enterprises-with-subsidiaries-more-prone-to-cyberattacks-study-says.html

Cisco Talos Reports New Variant Of Babuk Ransomware Targeting Exchange Servers

Cisco Talos has a warning out for companies about a new variant of the Babuk ransomware. The security researchers discovered the campaign in mid-October and think that the variant has been active since July 2021. The new element in this attack is an unusual infection chain technique.

The researchers think that the initial infection vector is an exploitation of ProxyShell vulnerabilities in Microsoft Exchange Server through the deployment of China Chopper web shell.

Babuk can affect several hardware and software platforms but this version is targeting Windows. The ransomware encrypts the target's machine, interrupts the system backup process and deletes the volume shadow copies. https://www.techrepublic.com/article/cisco-talos-reports-new-variant-of-babuk-ransomware-targeting-exchange-servers/

Ransomware Gangs Target Corporate Financial Activities

The FBI is warning about a fresh extortion tactic: threatening to tank share prices for publicly held companies.

Ransomware gangs are zeroing in on publicly held companies with the threat of financial exposure in an effort to encourage ransom payments, the FBI is warning.

In an alert issued this week the Bureau said that activity over the course of the past year shows a trend toward targeting companies when they’re coming up to “significant, time-sensitive financial events,” such as quarterly earnings reports and mandated SEC filings, initial public offerings, M&A activity, and so on. The idea is to ratchet up the extortion thumb-screws by threatening to leak stolen information relevant to these events if the target doesn’t pay up.

Impending events that could affect a victim’s stock value, such as announcements [or] mergers and acquisitions, encourage ransomware actors to target a network or adjust their timeline for extortion. https://threatpost.com/ransomware-corporate-financial/175940/

Web Of Deceit: The Rising Threat Of Ransomware

With payouts of almost £260m last year alone, it has become the biggest – and easiest – money-earner available to hackers.

Heists at famous jewellers usually involve masked men, guns, shouting and terrified staff and customers. That was indeed the scene in August 2009 at the London branch of Graff, the famous diamond merchants, when a gang stole around £40million worth of jewels. They were caught not long after.

But the latest heist on Graff, revealed recently, was quieter. No guns, no masks, no shouting. Instead the company – which supplies a dizzying parade of top-name stars such as the Beckhams, Tom Hanks and Tamara Ecclestone – faced a demand, displayed on a computer screen, for millions of pounds, payable to a group of Russian hackers.

Graff, like hundreds of companies around the world, had been hit by “ransomware”: an attachment to an email delivered a malicious program which let in hackers, who scrambled all the files on its computer systems using an uncrackable computer code, for which they had the digital “key”.

They’d hand it over in exchange for a payment worth millions of pounds in untraceable cryptocurrency such as bitcoin, where transactions are made between digital “wallets” that do not pass through any bank and are not tied to any identity.

Without the key, the systems are useless. The option is to restore the system from backups – but frequently the hackers will have targeted those too. https://www.telegraph.co.uk/news/2021/11/06/web-deceit-rising-threat-ransomware/

While Businesses Are Ramping Up Their Risk Mitigation Efforts, They Could Be Doing More

Zurich North America and Advisen have released a survey of corporate risk managers and insurance buyers revealing current views about information security and cyber risk management.

The survey results indicate that risk professionals are increasingly aware of their intensifying cyber risks and the need to manage them using risk mitigation and risk transfer. However, a deeper dive into the numbers found that there is much room for improvement in building cyber resilience.

Sixty-five percent of respondents have invested in cyber security solutions to mitigate risk, which means that 35 percent of respondents still have not. https://www.helpnetsecurity.com/2021/11/03/gaps-risk-mitigation-efforts/

Top Cyber Stories of the Last Week

Ransomware Attacks Soar 288% in First Half of 2021

The number of ransomware attacks surged by 288% between the first and second quarters of 2021 as double extortion attempts grew, according to the latest data.

Nearly a quarter (22%) of data leaks in the second quarter came from the Conti ransomware group, who typically gain initial network access to victim organisations via phishing emails.

It’s an unfortunate fact that no organisation in any sector is safe from ransomware today.

Targets range from IT companies and suppliers to financial institutions and critical national infrastructure providers, with ransomware-as-a-service increasingly being sold by ransomware gangs in a subscription model. https://www.infosecurity-magazine.com/news/ransomware-attacks-soar-half-2021/

Ransomware Costs Expected To Reach $265 Billion By 2031

Think ransomware is expensive now? It’s not predicted to get any cheaper over the next decade. Ransoms could cost victims a collective total of $265 billion by 2031. The estimate is based on the prediction that the price tag will increase 30% every year over the next 10 years. https://securityintelligence.com/news/ransomware-costs-expected-265-billion-2031/

Brute Force Email Attacks and Account Takeover Attempts Rise 671%, Reaching Unprecedented Levels, Causing Financial And Reputational Damage

A new Email Threat Report for Q3 2021 examines the escalating adverse impact of socially-engineered and never-seen-before email attacks, and other advanced email threats—both financial and reputational—to organisations worldwide. The report surveyed advanced email attacks across eight major industry sectors, including retail and consumer goods, manufacturing, technology, energy and infrastructure services, medical, media and television, finance, and hospitality.

The report also finds 61% of organisations experienced a vendor email compromise/supply chain attack in Q2 2021.

Key report findings include:

32.5% of all companies were targeted by brute force attacks in early June 2021
137 account takeovers occurred per 100,000 mailboxes for members of the C-suite
61% of organisations experienced a vendor email compromise attack this quarter
22% more business email compromise attacks since Q4 2020
60% chance of a successful account takeover each week for organisations with 50,000+ employees
73% of all advanced threats were credential phishing attacks
80% probability of attack every week for retail and consumer goods, technology, and media and television companies

Investigation Into Hacked "Map" Of UK Gun Owners

Gun-selling site Guntrader announced a data breach affecting more than 100,000 customers in July. This week, reports emerged that an animal rights activist blog had published the information. The group had formatted the data so it could be easily imported into mapping software to show individual homes. The National Crime Agency, which has been investigating the data breach and its fallout, said it "is aware that information has been published online as a result of a recent data breach which impacted Guntrader". https://www.bbc.co.uk/news/technology-58413847

Eight US Financial Services Firms Given Six-Figure Fines Over BEC Data Breaches

The US Securities and Exchange Commission (SEC) has sanctioned multiple financial services firms for cyber security failures that led to the compromise of corporate email accounts and the personal data of thousands of individuals. The case was brought after the unauthorised takeover of cloud-based email accounts at Seattle-based KMS Financial Services, and subsidiaries of California-headquartered Cetera Financial Group and Iowa-based Cambridge Investment Group. https://portswigger.net/daily-swig/eight-us-financial-services-firms-given-six-figure-fines-over-bec-data-breaches

Ransomware Has Been A ‘Game Changer’ For Cyber Insurance

Ransomware attacks accounted for nearly one quarter of all cyber incidents globally last year, according to a software company. The researchers “think of December 2019 as the tipping point for when we started to see ransomware take hold”. The U.S. was hit by a barrage of ransomware attacks in 2019 that impacted at least 966 government agencies, educational establishments, and healthcare providers at a potential cost in excess of $7.5 billion. All of this has a massive knock-on affect for the Insurance firms. https://www.insurancejournal.com/news/national/2021/08/30/628672.htm

Getting Ahead Of A Major Blind Spot For CISOs: Third-Party Risk

For many CISOs and security leaders, it was not long ago that their remit focused on the networks and digital ecosystems for their organisation alone. In today’s digital world, those days are a thing of the past with a growing number of businesses relying on third-party vendors to scale, save time and outsource expertise to stay ahead. With this change, new security risks affiliated with third-party vendors are more prevalent than ever before. https://www.helpnetsecurity.com/2021/09/01/getting-ahead-of-a-major-blind-spot-for-cisos-third-party-risk/

WhatsApp Hit With $267 Million GDPR Fine For Bungling User Privacy Disclosure

Ireland’s Data Protection Commission fined Facebook-owned messenger WhatsApp for $225 million for failing to provide users enough information about the data it shared with other Facebook companies.

The fine is the largest penalty that the Irish regulator has waged since the European Union data protection law, the General Data Protection Regulation, or GDPR, went into effect in 2018. https://www.cyberscoop.com/whatsapp-hit-with-267-million-gdpr-fine-for-bungling-user-privacy-disclosure/

Microsoft Warns About Open Redirect Phishing Campaign

Microsoft’s Security Intelligence team is warning over phishing campaigns using open redirector links, links crafted to subvert normal inspection efforts. Smart users know to hover over links to see where they're going to lead, but these links are prepared for that type of user and display a safe destination designed to lure targets into a false sense of security. Click the link and you'll be redirected to a domain that appears legit (such as a Microsoft 365 login page, for example) and sets the stage for you to voluntarily hand over credentials to bad actors without even realising it until it's too late. https://www.windowscentral.com/microsoft-warns-about-open-redirect-phishing-campaign

Previous Employees With Access To Corporate Data Remain A Threat To Businesses

Offboarding employees securely is a key problem for business leaders, with 40% concerned that employees who leave a company retain knowledge of passwords that grant access to corporate data. This is according to a report, which found few organisations are implementing access management solutions that work with all applications, meaning most lack the ability to revoke access to all corporate data as soon as an employee leaves. https://www.helpnetsecurity.com/2021/09/02/previous-employees-access-data/

BEC Scammers Seek Native English Speakers On Underground

Looking for work? Speak fluent English? Capable of convincingly portraying a professional – as in, somebody a highly ranked corporate leader would talk to? If you lack scruples and disregard those pesky things called “laws,” it could be your lucky day: Cyber Crooks are putting up help-wanted ads, looking for native English speakers to carry out the social-engineering elements of business email compromise (BEC) attacks. https://threatpost.com/bec-scammers-native-english-speakers/169092/

Half Of Businesses Can't Spot These Signs Of Insider Cyber Security Threats

Most businesses are struggling to identify and detect early indicators that could suggest an insider is plotting to steal data or carry out other cyber attacks. Research suggests that over half of companies find it impossible or very difficult to prevent insider attacks. These businesses are missing indicators that something might be wrong. Those include unusual amounts of files being opened, attempts to use USB devices, staff purposefully circumventing security controls, masking their online activities, or moving and saving files to unusual locations. All these and more might suggest that a user is planning malicious activity, including the theft of company data. https://www.zdnet.com/article/half-of-businesses-cant-spot-these-signs-of-insider-cybersecurity-threats/
