New research has uncovered Docker images on Docker Hub that contain the infamous XZ Utils backdoor, more than a year after the discovery of the incident. More troubling is the fact that other images have been built on top of these infected base images, effectively propagating the infection further in a transitive manner, Binarly REsearch said in a report shared with The Hacker News. The firmware security company said it discovered a total of 35 images that ship with the backdoor. The incident once again highlights the risks faced by the software supply chain. The XZ Utils supply chain event (CVE-2024-3094, CVSS score: 10.0) came to light in late March 2024, when Andres Freund sounded the alarm on a backdoor embedded within XZ Utils versions 5.6.0 and 5.6.1. Further analysis of the malicious code and the broader compromise led to several startling discoveries , the first and foremost being that the backdoor could lead to unauthorized remote access and enable the execution of ar...

Cybersecurity researchers are warning of a "significant spike" in brute-force traffic aimed at Fortinet SSL VPN devices. The coordinated activity, per threat intelligence firm GreyNoise, was observed on August 3, 2025, with over 780 unique IP addresses participating in the effort. As many as 56 unique IP addresses have been detected over the past 24 hours. All the IP addresses have been classified as malicious, with the IPs originating from the United States, Canada, Russia, and the Netherlands. Targets of the brute-force activity include the United States, Hong Kong, Brazil, Spain, and Japan. "Critically, the observed traffic was also targeting our FortiOS profile, suggesting deliberate and precise targeting of Fortinet's SSL VPNs," GreyNoise said . "This was not opportunistic -- it was focused activity." The company also pointed out that it identified two distinct assault waves spotted before and after August 5: One, a long-running, brute-force a...

An ongoing data extortion campaign targeting Salesforce customers may soon turn its attention to financial services and technology service providers, as ShinyHunters and Scattered Spider appear to be working hand in hand, new findings show. "This latest wave of ShinyHunters-attributed attacks reveals a dramatic shift in tactics, moving beyond the group's previous credential theft and database exploitation," ReliaQuest said in a report shared with The Hacker News. These include the use of adoption of tactics that mirror those of Scattered Spider , such as highly-targeted vishing (aka voice phishing ) and social engineering attacks, leveraging apps that masquerade as legitimate tools, employing Okta-themed phishing pages to trick victims into entering credentials during vishing, and VPN obfuscation for data exfiltration. ShinyHunters , which first emerged in 2020, is a financially motivated threat group that has orchestrated a series of data breaches targeting major...

A previously undocumented threat actor dubbed Curly COMrades has been observed targeting entities in Georgia and Moldova as part of a cyber espionage campaign designed to facilitate long-term access to target networks. "They repeatedly tried to extract the NTDS database from domain controllers -- the primary repository for user password hashes and authentication data in a Windows network," Bitdefender said in a report shared with The Hacker News. "Additionally, they attempted to dump LSASS memory from specific systems to recover active user credentials, potentially plain-text passwords, from machines where users were logged on." The activity, tracked by the Romanian cybersecurity company since mid-2024, has singled out judicial and government bodies in Georgia, as well as an energy distribution company in Moldova. "Regarding the timeline, while we have been tracking the campaign since mid-2024, our analysis of the artifacts indicates that activity began e...

Most security tools can't see what happens inside the browser, but that's where the majority of work, and risk, now lives. Security leaders deciding how to close that gap often face a choice: deploy a dedicated Enterprise Browser or add an enterprise-grade control layer to the browsers employees already use and trust. The Ultimate Battle: Enterprise Browsers vs. Enterprise Browser Extensions examines this choice across nine "rounds": adoption, data protection, BYOD, productivity, management overhead, remote access, Zero Trust alignment, supply-chain security, and future-readiness, to show where each approach excels, and where trade-offs emerge. Each round uses practical, enterprise scenarios to compare the two models, making it easier to see not just what they can do, but how they perform at scale. The Browser Is Now the Workspace The browser has become the primary workspace for enterprise users. It is where sensitive data is created, accessed, and moved through copy/paste action...

The Dutch National Cyber Security Centre (NCSC-NL) has warned of cyber attacks exploiting a recently disclosed critical security flaw impacting Citrix NetScaler ADC products to breach organizations in the country. The NCSC-NL said it discovered the exploitation of CVE-2025-6543 targeting several critical organizations within the Netherlands, and that investigations are ongoing to determine the extent of the impact. CVE-2025-6543 (CVSS score: 9.2) is a critical security vulnerability in NetScaler ADC that results in unintended control flow and denial-of-service (DoS) when the devices are configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) OR AAA virtual server.

Cybersecurity researchers have discovered a fresh set of security issues in the Terrestrial Trunked Radio (TETRA) communications protocol, including in its proprietary end-to-end encryption (E2EE) mechanism that exposes the system to replay and brute-force attacks, and even decrypt encrypted traffic. Details of the vulnerabilities – dubbed 2TETRA:2BURST – were presented at the Black Hat USA security conference last week by Midnight Blue researchers Carlo Meijer, Wouter Bokslag, and Jos Wetzels. TETRA is a European mobile radio standard that's widely used by law enforcement, military, transportation, utilities, and critical infrastructure operators. It was developed by the European Telecommunications Standards Institute (ETSI). It encompasses four encryption algorithms: TEA1, TEA2, TEA3, and TEA4. The disclosure comes a little over two years after the Netherlands-based cybersecurity company discovered a set of security vulnerabilities in TETRA standard called TETRA:BURST, c...

Malicious actors have been observed exploiting a now-patched critical security flaw impacting Erlang/Open Telecom Platform (OTP) SSH as early as beginning of May 2025, with about 70% of detections originating from firewalls protecting operational technology (OT) networks. The vulnerability in question is CVE-2025-32433 (CVSS score: 10.0), a missing authentication issue that could be abused by an attacker with network access to an Erlang/OTP SSH server to execute arbitrary code. It was patched in April 2025 with versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. Then in June 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the flaw to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation. "At the heart of Erlang/OTP's secure communication capabilities lies its native SSH implementation — responsible for encrypted connections, file transfers and most importantly, command execution," Palo Alto Networks U...

The Evolution of Exposure Management Most security teams have a good sense of what's critical in their environment. What's harder to pin down is what's business-critical . These are the assets that support the processes the business can't function without. They're not always the loudest or most exposed. They're the ones tied to revenue, operations, and delivery. If one goes down, it's more than a security issue – It's a business problem. Over the past year since publishing our 4-step approach to mapping and securing business-critical assets, my team and I have had the opportunity to engage deeply with dozens of customer workshops across multiple industry verticals, including finance, manufacturing, energy, and more. These sessions have revealed valuable insights into how organizations are evolving their security posture.  This article takes an updated look at that approach, incorporating what we have learned along the way, helping organizations align exposure management strate...

The maintainers of the WinRAR file archiving utility have released an update to address an actively exploited zero-day vulnerability. Tracked as CVE-2025-8088 (CVSS score: 8.8), the issue has been described as a case of path traversal affecting the Windows version of the tool that could be exploited to obtain arbitrary code execution by crafting malicious archive files. "When extracting a file, previous versions of WinRAR, Windows versions of RAR, UnRAR, portable UnRAR source code and UnRAR.dll can be tricked into using a path, defined in a specially crafted archive, instead of a specified path," WinRAR said in an advisory. Anton Cherepanov, Peter Kosinar, and Peter Strycek from ESET have been credited for discovering and reporting the security defect, which has been addressed in WinRAR version 7.13 released on July 31, 2025. The development is the second time a WinRAR security vulnerability has been weaponized in the wild in as many years. In 2023, another vulnerabil...

A novel attack technique could be weaponized to rope thousands of public domain controllers (DCs) around the world to create a malicious botnet and use it to conduct powerful distributed denial-of-service (DDoS) attacks. The approach has been codenamed Win-DDoS by SafeBreach researchers Or Yair and Shahak Morag, who presented their findings at the DEF CON 33 security conference today. "As we explored the intricacies of the Windows LDAP client code, we discovered a significant flaw that allowed us to manipulate the URL referral process to point DCs at a victim server to overwhelm it," Yair and Morag said in a report shared with The Hacker News. "As a result, we were able to create Win-DDoS, a technique that would enable an attacker to harness the power of tens of thousands of public DCs around the world to create a malicious botnet with vast resources and upload rates. All without purchasing anything and without leaving a traceable footprint." In transfor...
