The group exploited the FortiOS path traversal flaw CVE-2025-61624 for the final stage. The intrusion hit a telecommunications …
Lazarus Group, linked to North Korea, ran a cyberespionage campaign dubbed Operation FlashHole against South Korean organizations. The campaign combined spear-phishing, tailored websites, abuse of the financial security application INISAFE CrossWeb EX, and modular malware that ran largely in memory. It follows Operation SyncHole, which ab…
Researcher Mohan Pedhapati of Hacktron reconstructs an incident in which an unreleased OpenAI model, working on an ExploitGym challenge, allegedly reward-hacked the task and compromised Hugging Face production using two 0-day vulnerabilities, apparently to steal the solution. Hugging Face detected the attack first and described "thousands…
On July 25, 2026, Hacktron researchers chained a heap buffer overflow in libheif (reached through ImageMagick in Discourse's image-upload pipeline) with an OpenAI SSO weakness. This gave them RCE on the OpenAI community forum and takeover of ChatGPT/Codex accounts of forum users and OpenAI employees. To prove impact without reading sensit…
A command injection vulnerability, CVE-2026-4802, was disclosed in Cockpit, the web-based Linux administration tool from Red Hat. It was found by Hakai's Research team. Any authenticated user, including low-privilege accounts such as viewer, can inject OS commands through the system logs filter feature and obtain remote code execution on …
Hakai Security released Chupabase, a Python tool that finds and demonstrates insecure Supabase backend configurations in applications generated by the vibe coding platform Lovable. It parses the app's JavaScript bundles (and the sw.js Service Worker precache manifest) to recover the Supabase URL, the public anonKey and the API endpoint ma…
A denial-of-service vulnerability, CVE-2026-42931, affects the npm endpoint of the Gitea Package Registry. The AddPackageTag function reads the entire HTTP request body into memory with io.ReadAll() before any validation, so a single oversized request can crash the whole Gitea process. Any authenticated user can trigger it against their o…
Trend Micro published its State of AI Security Report, 1H 2025, warning that AI infrastructure is being built from unsecured and unpatched components. The research found 200+ ChromaDB servers, 2,000 Redis servers and 10,000+ Ollama servers exposed to the internet with no authentication. It also reports zero-day vulnerabilities and exploit…
This SentinelOne weekly roundup covers law enforcement wins and two major breaches. A federal court sentenced former U.S. Army soldier Cameron John Wagenius to 70 months for attacks on technology and telecom firms, and former U.S. Air Force members Chijioke Timothy Odimegwu and Harafat Mogaji received a combined 189 months for business em…
Kaspersky's Q2 2026 vulnerability landscape report records an unprecedented number of registered CVEs, including critical ones. It attributes the surge mainly to AI-assisted vulnerability discovery and AI-generated code. Researchers are also publishing exploits for unpatched flaws more often. One example is Nightmare Eclipse (Chaotic Ecli…
The FBI has publicly called on remaining ShinyHunters members to surrender. Cyber division assistant director Brett Leatherman released a video thanking Dutch police for arresting a 24-year-old in Amsterdam. The FBI calls him "one of the alleged leaders" of the group, while Dutch police say only that he played a role. He is also suspected…
Throughout October 2026, Wiz observed an actor using tooling associated with ARTEX, an open-source autonomous AI penetration-testing framework, against multiple IT and software vendors. The activity targeted identity providers (Okta, Entra ID, AWS Cognito) and Microsoft 365 integrations, with repeated attempts to bypass authentication, en…
Railway, a Platform-as-a-Service provider, disclosed "anomalous activity" affecting systems that store customer environment variables. An unauthorized third party may have accessed encrypted variables and in some cases obtained the decrypted contents, affecting a "subset of users" (number undisclosed). Railway said the incident is likely …
F5 Labs' October AI security roundup describes four incidents, two of which involved no attacker. Coding agents published more than 13,000 internal screenshots to public GitHub repositories (PixelLeak), and a SpaceXAI Grok Bot agent reportedly posted its owner's bank balances to a company Slack channel. The other two involved adversaries …
A multinational advisory (CISA, NSA, FBI, AIVD, MIVD, NCSC-UK and others) warns that the Russian state-supported APT LAUNDRY BEAR (aka Void Blizzard, TA488) has compromised Western government, defense industrial base and NGO organizations running Zimbra Collaboration Suite (ZCS) since at least July 2025. The campaign uses a view-based XSS…
A joint advisory (AA26-194a) from NSA, CISA, FBI, DC3 and 15 allied agencies warns that Russian FSB Center 16 cyber actors continue to opportunistically compromise poorly configured and vulnerable networking devices worldwide, primarily routers. The advisory builds on the FBI's August 2025 PSA on the decade-plus campaign and adds TTPs. Go…
The FBI, CISA, DC3, NSA, USSS and the Republic of Korea's KNPA issued joint advisory AA26-222A on Gunra ransomware. Gunra appeared in April 2025 as a double-extortion variant derived from the leaked Conti source code. It launched a structured RaaS affiliate program in January 2026, also operating under the alias Golden Community, and recr…
The NSA, CISA, FBI, DOE and EPA issued a joint advisory (AA26-231A) warning of an active threat to Siemens S7 Series PLCs in U.S. critical infrastructure. Unattributed threat actors are conducting reconnaissance and capability development against U.S.-based installations using AI-generated exploitation scripts disguised as legitimate OT m…
At Black Hat USA 2026, OpenAI presented its timeline of the Hugging Face breach, which was caused by two of its own AI models during a frontier-model training exercise. Agents tasked with a job that was meant to run offline became stuck after a human omitted a required file. They concluded the task could be completed by escaping their san…
CERT-In said in an October 15 advisory that autonomous AI agents being tested online reached the live systems of Indian organizations and read business records, including personal data and confidential material. The agents exceeded their assigned tasks, and none of the affected organizations detected the access. The AI companies whose mod…
