Businesses across the world have been hit by widespread disruptions to their Windows workstations stemming from a faulty update pushed out by cybersecurity company CrowdStrike. "CrowdStrike is actively working with customers impacted by a defect found in a single content update for Windows hosts," the company's CEO George Kurtz said in a statement . "Mac and Linux hosts are not impacted. This is not a security incident or cyber attack." The company, which acknowledged "reports of [ Blue Screens of Death ] on Windows hosts," further said it has identified the issue and a fix has been deployed for its Falcon Sensor product, urging customers to refer to the support portal for the latest updates. For systems that have been already impacted by the problem, the mitigation instructions are listed below - Boot Windows in Safe Mode or Windows Recovery Environment Navigate to the C:\Windows\System32\drivers\CrowdStrike directory Find the file named &qu

The financially motivated threat actor known as FIN7 has been observed using multiple pseudonyms across several underground forums to likely advertise a security dodging tool known to be used by ransomware groups like AvosLocker, Black Basta, BlackCat, LockBit, and Trigona. "AvNeutralizer (aka AuKill ), a highly specialized tool developed by FIN7 to tamper with security solutions, has been marketed in the criminal underground and used by multiple ransomware groups," cybersecurity company SentinelOne said in a report shared with The Hacker News. FIN7, an e-crime group of Russian and Ukrainian origin, has been a persistent threat since at least 2012, shifting gears from its initial targeting of point-of-sale (PoS) terminals to acting as a ransomware affiliate for now-defunct gangs such as REvil and Conti, before launching its own ransomware-as-a-service (RaaS) programs DarkSide and BlackMatter. The threat actor, which is also tracked under the names Carbanak, Carbon Spide

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

Threat actors are actively exploiting a recently disclosed critical security flaw impacting Apache HugeGraph-Server that could lead to remote code execution attacks. Tracked as CVE-2024-27348 (CVSS score: 9.8), the vulnerability impacts all versions of the software before 1.3.0. It has been described as a remote command execution flaw in the Gremlin graph traversal language API. "Users are recommended to upgrade to version 1.3.0 with Java11 and enable the Auth system, which fixes the issue," the Apache Software Foundation noted in late April 2024. "Also you could enable the 'Whitelist-IP/port' function to improve the security of RESTful-API execution." Additional technical specifics about the flaw were released by penetration testing company SecureLayer7 in early June, stating it enables an attacker to bypass sandbox restrictions and achieve code execution, giving them complete control over a susceptible server. This week, the Shadowserver Foundat

Russian security vendor Kaspersky has said it's exiting the U.S. market nearly a month after the Commerce Department announced a ban on the sale of its software in the country citing a national security risk. News of the closure was first reported by journalist Kim Zetter. The company is expected to wind down its U.S. operations on July 20, 2024, the same day the ban comes into effect. It's also expected to lay off less than 50 employees in the U.S. "The company has carefully examined and evaluated the impact of the U.S. legal requirements and made this sad and difficult decision as business opportunities in the country are no longer viable," the company said in a statement. In late June 2024, the Commerce Department said it was enforcing a ban after what it said was an "extremely thorough investigation." The company was also added to the Entity List, preventing U.S. enterprises from conducting business with it. It's currently not known what was

Unknown threat actors have been observed exploiting a now-patched security flaw in Microsoft MSHTML to deliver a surveillance tool called MerkSpy as part of a campaign primarily targeting users in Canada, India, Poland, and the U.S. "MerkSpy is designed to clandestinely monitor user activities, capture sensitive information, and establish persistence on compromised systems," Fortinet FortiGuard Labs researcher Cara Lin said in a report published last week. The starting point of the attack chain is a Microsoft Word document that ostensibly contains a job description for a software engineer role. But opening the file triggers the exploitation of CVE-2021-40444 , a high-severity flaw in MSHTML that could result in remote code execution without requiring any user interaction. It was addressed by Microsoft as part of Patch Tuesday updates released in September 2021. In this case, it paves the way for the download of an HTML file ("olerender.html") from a remote s

Multiple content management system (CMS) platforms like WordPress, Magento, and OpenCart have been targeted by a new credit card web skimmer called Caesar Cipher Skimmer. A web skimmer refers to malware that is injected into e-commerce sites with the goal of stealing financial and payment information .  According to Sucuri, the latest campaign entails making malicious modifications to the checkout PHP file associated with the WooCommerce plugin for WordPress ("form-checkout.php") to steal credit card details. "For the past few months, the injections have been changed to look less suspicious than a long obfuscated script," security researcher Ben Martin said , noting the malware's attempt to masquerade as Google Analytics and Google Tag Manager. Specifically, it utilizes the same substitution mechanism employed in Caesar cipher to encode the malicious piece of code into a garbled string and conceal the external domain that's used to host the payload.

The security risks posed by the Pickle format have once again come to the fore with the discovery of a new "hybrid machine learning (ML) model exploitation technique" dubbed Sleepy Pickle. The attack method, per Trail of Bits, weaponizes the ubiquitous format used to package and distribute machine learning (ML) models to corrupt the model itself, posing a severe supply chain risk to an organization's downstream customers. "Sleepy Pickle is a stealthy and novel attack technique that targets the ML model itself rather than the underlying system," security researcher Boyan Milanov said . While pickle is a widely used serialization format by ML libraries like PyTorch , it can be used to carry out arbitrary code execution attacks simply by loading a pickle file (i.e., during deserialization). "We suggest loading models from users and organizations you trust, relying on signed commits, and/or loading models from [TensorFlow] or Jax formats with the from_

As many as 165 customers of Snowflake are said to have had their information potentially exposed as part of an ongoing campaign designed to facilitate data theft and extortion, indicating the operation has broader implications than previously thought. Google-owned Mandiant, which is assisting the cloud data warehousing platform in its incident response efforts, is tracking the as-yet-unclassified activity cluster under the name UNC5537 , describing it as a financially motivated threat actor. "UNC5537 is systematically compromising Snowflake customer instances using stolen customer credentials, advertising victim data for sale on cybercrime forums, and attempting to extort many of the victims," the threat intelligence firm said on Monday. "UNC5537 has targeted hundreds of organizations worldwide, and frequently extorts victims for financial gain. UNC5537 operates under various aliases on Telegram channels and cybercrime forums." There is evidence to suggest tha

Staying Sharp: Cybersecurity CPEs Explained Perhaps even more so than in other professional domains, cybersecurity professionals constantly face new threats. To ensure you stay on top of your game, many certification programs require earning Continuing Professional Education (CPE) credits. CPEs are essentially units of measurement used to quantify the time and effort professionals spend on maintaining and enhancing skills and knowledge in the field of cybersecurity, and they act as points that demonstrate a commitment to staying current. CPEs are best understood in terms of other professions: just like medical, legal and even CPA certifications require continuing education to stay up-to-date on advancements and industry changes, cybersecurity professionals need CPEs to stay informed about the latest hacking tactics and defense strategies. CPE credits are crucial for maintaining certifications issued by various cybersecurity credentialing organizations, such as (ISC)², ISACA, and C

The U.S. Federal Bureau of Investigation (FBI) has disclosed that it's in possession of more than 7,000 decryption keys associated with the LockBit ransomware operation to help victims get their data back at no cost. "We are reaching out to known LockBit victims and encouraging anyone who suspects they were a victim to visit our Internet Crime Complaint Center at ic3.gov," FBI Cyber Division Assistant Director Bryan Vorndran said in a keynote address at the 2024 Boston Conference on Cyber Security (BCCS). LockBit, which was once a prolific ransomware gang, has been linked to over 2,400 attacks globally, with no less than 1,800 impacting entities in the U.S. Earlier this February, an international law enforcement operation dubbed Cronos led by the U.K. National Crime Agency (NCA) dismantled its online infrastructure. Last month, a 31-year-old Russian national named Dmitry Yuryevich Khoroshev was outed by authorities as the group's administrator and developer, a

Zyxel has released security updates to address critical flaws impacting two of its network-attached storage (NAS) devices that have currently reached end-of-life (EoL) status. Successful exploitation of three of the five vulnerabilities could permit an unauthenticated attacker to execute operating system (OS) commands and arbitrary code on affected installations. Impacted models include NAS326 running versions V5.21(AAZF.16)C0 and earlier, and NAS542 running versions V5.21(ABAG.13)C0 and earlier. The shortcomings have been resolved in versions V5.21(AAZF.17)C0 and V5.21(ABAG.14)C0, respectively. A brief description of the flaws is as follows - CVE-2024-29972 - A command injection vulnerability in the CGI program "remote_help-cgi" that could allow an unauthenticated attacker to execute some operating system (OS) commands by sending a crafted HTTP POST request CVE-2024-29973 - A command injection vulnerability in the 'setCookie' parameter that could allow a

The online criminal bazaar BreachForums has been resurrected merely two weeks after a U.S.-led coordinated law enforcement action dismantled and seized control of its infrastructure. Cybersecurity researchers and dark web trackers Brett Callow , Dark Web Informer , and FalconFeeds revealed the site's online return at breachforums[.]st – one of the dismantled sites – by a user named ShinyHunters, who has since offered for sale a 1.3 TB database containing details of allegedly 560 million Ticketmaster customers for $500,000. This includes full names, addresses, email addresses, phone numbers, ticket sales and event information, and the last four digits of credit cards and their associated expiration dates. However, in an interesting twist, visitors of the site are now being asked to sign up for an account in order to view the content. The development follows a joint law enforcement action that seized all the new domains belonging to BreachForums (breachforums[.]st/.cx/.is/.

You're probably familiar with the term "critical assets". These are the technology assets within your company's IT infrastructure that are essential to the functioning of your organization. If anything happens to these assets, such as application servers, databases, or privileged identities, the ramifications to your security posture can be severe.  But is every technology asset considered a critical asset? Moreover, is every technology asset considered a  business -critical asset? How much do we really know about the risks to our  business -critical assets?  Business-critical assets are the underlying technology assets of your business in general – and we all know that technology is just one of the 3 essential pillars needed for a successful business operation. In order to have complete cybersecurity governance, organizations should consider: 1) Technology, 2) Business processes, and 3) Key People. When these 3 pillars come together, organizations can begin to understand the
