Google has jumped on the AI-defense-for-critical-systems train with its Scan for Good initiative, and says that its threat-hunting models have already autonomously uncovered critical security issues at hospitals, a municipality, a public rail operator, and major technology providers. So don't fear these bots. The initiative, announced on Thursday, uses Google’s Gemini 3.8 Flash Cyber, a version of the model tuned for software bug hunting and remediation, and Wiz’s Red Agent - this is the Google-owned cloud security shop’s pentesting AI agent. The AI systems will uncover public exposures and…

Security researchers affiliated with Austria's Graz University of Technology have found flaws in the implementation of file notification systems on Android, Linux, macOS, and Windows that leak potentially compromising system information. "We found decades-old bugs on [these operating systems], all rooted in the file-notification subsystems that every modern OS ships to inform applications when files change," said Sudheendra Raghav Neela, a doctoral student at TU Graz, in an email to The Register. Affected systems include inotify on Linux since 2005, FileObserver on Android since 2008…

The "third-party[.]com" domain, commonly used as a documentation placeholder, has been observed serving a ClickFix lure to Windows browsers while displaying a harmless decoy to other users. "third-party[.]com has been a generic documentation placeholder for years, the same role example.com plays," Manifold Security's Head of Research, Ax Sharma, said. "Unlike 'example[.]com,' third-party[.]com

Well, well, well, well, well, well, well, well, well, well, well, well, well, well, well. We're back. Sorry. We've been watching the onslaught of vulnerabilities flood the internet. Every man, dog, and their grandmas (apparently?) are now using LLMs to find and reproduce vulnerabilities - it’s a free-for-all (unless you’re trying to buy RAM). Unfortunately, while we're all finding more vulnerabilities and flexing obfuscated stack traces… (or emoji-ridden HTTP requests that are actually complete slop and not real, and please, for the love of god, no, those slop-ridden payloads appearing in…

Security teams already have long queues of potential application vulnerabilities. The useful question is what happens next: can they see how a weakness behaves in a running application, reproduce the attack, and give developers enough evidence to fix it? Dynamic application security testing (DAST) helps answer those questions by testing applications as an attacker encounters them. The IDC MarketScape: Worldwide Dynamic Application Security Testing 2026 Vendor Assessment (Doc #US54119126, September 2026). The IDC MarketScape evaluated 16 vendors and named Rapid7 a Leader. We believe the result…

The private email address GitLab gives you for filing issues by email is a credential. Anyone who gets it can email a patch that GitLab commits in your name, to any branch you can push to, including main, and can start CI/CD jobs that run as you. GitLab shows each user this address behind a button labeled "Email work item to this project." Mail sent to it opens an issue in that project, authored

A zero-day proof-of-concept tool that stops Microsoft Defender from installing platform and signature updates by filling all available disk space was published on GitHub on September 19. The tool, called BigDiskBuster, has no patch, no CVE, and no Microsoft advisory. Its author, Abdelhamid Naceri, is a former Microsoft security researcher whose earlier Defender exploits were used in

Check Point has warned that attackers are actively exploiting two critical vulnerabilities in its VPN and management products, allowing unauthenticated remote access and possible remote code execution. Both flaws carry a CVSS severity score of 9.8, and the company has released fixes that affected organizations should apply immediately. The first issue, tracked as CVE-2026-85102, affects Check Point Security Gateway and Spark Firewall deployments that use Remote Access VPN or certificate-based Site-to-Site VPN authentication. The flaw stems from improper validation of certificate data during…

Threat actors have begun to actively exploit a critical security flaw in WordPress within hours of public disclosure. The vulnerability in question is CVE-2026-87902 (CVSS score: 9.2), which could allow an unauthenticated attacker to obtain remote code execution (RCE). "An unauthenticated attacker can make get_page_template() page-template resolution include a chosen readable local .php file
