Cisco has released patches to address a critical security flaw affecting 10 Silicon One-based Nexus 9000 switches that could allow an unauthenticated, remote attacker to execute code as root, alongside an IOS XR hardening release bundling 7 umbrella CVEs, 2 of which are rated 9.8, with no workaround for any IOS XR version. The Nexus vulnerability, tracked as CVE-2026-20212 (CVSS score: 9.8), is a case of binding to an unrestricted IP address that leaves TCP ports 43210 and 43211 reachable in the default Layer 3 virtual routing and forwarding (VRF) instance. An attacker who can reach a switch's address on either port can connect directly to the service. Crafted input sent to that service is then executed as code with root privileges. An exploitation attempt can also crash the S1HAL process and reload the device. Cisco said it's not aware of any malicious use of the flaw as of its September 2 disclosure. It has published no fixed-release table and directs customers to its...

Cybersecurity researchers have disclosed details of a sophisticated Python-based Windows malware framework called BraZetsu that fuels an underground marketplace commercializing access to compromised hosts. "Unlike the standard infostealer model, BraZetsu is a comprehensive master toolkit that empowers Initial Access Brokers (IABs) by turning compromised systems into highly valuable commercial assets," Group-IB malware analysts Julio Guapo Menezes and Miguel Salazar said in a technical report. "The framework exhibits high operational maturity, utilizing a modular architecture and stealth techniques that allowed some samples to remain fully undetectable on VirusTotal at the time of analysis." BraZetsu is a portmanteau of "Brazil" and "Zetsu," a fictional character from the Japanese Manga series Naruto who is known to operate as a threat from the shadows. The naming is inspired by the fact that the initial access tool stealthily infiltrat...

Thomson Reuters disclosed on Wednesday that an unauthorized party obtained files from C-Track , the court case management platform sold by its West Publishing Corporation unit, in March 2026, affecting courts in 11 U.S. states, the U.S. Virgin Islands, and Ontario, Canada. West Publishing said it discovered the activity on June 30, 2026. A subset of court records could contain individuals' names, Social Security numbers, driver's license numbers, dates of birth, medical information, and health insurance information, the company said. The firm is offering potentially affected individuals 12 months of Experian IdentityWorks credit monitoring, with enrollment open until December 31, 2026, using a multi-use code published in the notice, and a hotline at 1-833-918-5294 that requires the engagement number B171847. In Canada, Thomson Reuters Canada Limited is offering 12 months of TransUnion myTrueIdentity monitoring with a call center scheduled to open on September 4. "...

An RMM phishing campaign initially associated with Canadian targeting due to its use of Canada Revenue Agency (CRA) tax forms as lures has turned out to be part of a broader campaign spanning 46 countries. Around 45% of observed activity was associated with the United States , making it the campaign's top geographic target. ANY.RUN research connected 601 cases to the wider operation, which uses fake documents to trick victims into installing legitimate remote monitoring and management (RMM) software. The attackers adapt their lures to different targets, using shipping and UPS communications, Adobe PDFs, tax notices, US Social Security Administration themes, invoices, and other documents. Rapidly rotated, disposable Vercel infrastructure makes the campaign harder to track and detect. US-First Threat with Daily Infrastructure Rotation Threat overview by ANY.RUN The campaign’s infrastructure changes significantly faster than its attack pattern. ANY.RUN researchers identifi...

Threat actors are leveraging the trusted Node.js JavaScript runtime in multiple cyber attacks as a way to deploy malicious payloads. According to a new report published by the Symantec Threat Hunter Team today, the attack method has been put to use in attacks targeting government departments, technology companies, and hotels since February 2026. "The technique's appeal is that node.exe (the binary that runs Node.js) is a legitimate, signed developer tool," the Broadcom-owned cybersecurity division said in a report shared with The Hacker News. "The attacker's malicious code lives in interpreted scripts rather than in a binary, making it less likely to trigger signature-based detection, while a registry Run key entry can relaunch the payload at every login." In one intrusion observed between March 23 and July 25, 2026, targeting an unspecified Asian technology company, attackers downloaded the official Node.js installer from nodejs[.]org and used the t...

In early August, GitGuardian researchers found that a recent Shai-Hulud infostealer worm variant had evolved to scan for credentials across 469 locations across developer environments , Continuous Integration/Continuous Deployment (CI/CD) tooling, cloud configurations, and even AI tool configs. Earlier variants of the infostealer worm only checked 189 paths. The jump says a lot. Attackers have stopped trying to break trust relationships and started using the credentials that already make those relationships work. Software supply chains have always depended on trust.  Developers trust package registries. Organizations trust maintainers. CI/CD systems trust the credentials and identities they're given. Applications trust the dependencies they pull down during a build.  Attackers realized they don't need to break any of that. They just needed to find where the credentials and standing privileges already sit. This is what is driving the current focus on software supply ...

The iPhone belonging to a member of Serbia's student protest movement was infected with NSO Group's Pegasus spyware , according to new findings from the Citizen Lab in collaboration with the SHARE Foundation. "Our analysis confirmed that an iMessage zero-click exploit was used to infect the device with NSO Group's Pegasus spyware," the Citizen Lab said . "We found high-confidence indicators of infection from a period across December 2025 – January 2026; however, this does not preclude the possibility of additional infections." It's assessed that the zero-click exploit used in the attack targeted Apple iMessage, and has been addressed by Apple with iOS 18.4.1 , which was released in April 2025. The discovery comes in the aftermath of Apple sending a new set of threat notifications to customers whom it suspected may have been targeted by mercenary spyware attacks. The alerts were sent to an unspecified number of users in 110 countries. In a...
