A Chinese-speaking operator used the open-source AI agent framework Cairn to run autonomous attacks against more than 1,200 sites, reaching websites of over 100 companies, including Deere, SharkNinja and Cummins. Researcher Snorre Fagerland of NorForge found the operation around 2 October 2026 by scanning for about two dozen exposed Cairn…
Threat actors are abusing the open source AI platform Cairn, an agent-coordination engine usable as an autonomous penetration testing tool, to automate attacks on hundreds of websites worldwide. AI security firm Norforge found the activity after threat actors left their Cairn panels exposed, following a Gambit Security report on attackers…
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…
Researcher ahacker1, using the Hacktron AI tooling, disclosed a bypass of earlier fixes for prompt-injection-to-RCE in VS Code Copilot Chat agent mode. A TOCTOU flaw in the applyPatchTool component lets a crafted prompt write files outside the workspace without user confirmation. The attack can be triggered by pasting a prompt into Copilo…
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…
Researcher Pedro Cruz (Hakai Security / The Hacking Club) disclosed nine vulnerabilities in widely used server-side PDF generation libraries, with a combined footprint of over 90 million monthly installs. The cases range from RCE (ReportLab, ReLaXed) through arbitrary file read and SSRF (WeasyPrint, Browsershot) to DoS and file/directory …
Two beta versions in the @joyfill npm scope, published on July 28, 2026, carried the same blockchain C2 loader seen in the earlier astro.config.mjs attack, which the article ties to the PolinRider campaign. The attacker published through the legitimate scope (a form-builder SDK with three maintainers) under the beta dist-tag. The maliciou…
F5 Labs honeynet telemetry shows overall hostile activity rising 55.5% month over month in June 2026, a return to the levels of the earlier-year spike. Highlighted is CVE-2024-44000, an unauthenticated account takeover flaw (CVSS 9.8, CWE-522) in the LiteSpeed Cache WordPress plugin, which rose by 1,128 to 2,603 attacks (8). Scanning is i…
FortiGuard Labs describes an intrusion in which a compromised Jenkins EC2 build host, tied to Shai Hulud persistence, was used to steal instance role credentials via IMDS and pivot into the victim's AWS environment. The actor used the credentials from external IPs, created an admin IAM user named cloudops-monitor, opened network paths to …
FortiGuard Labs analyzed a Casbaneiro banking trojan campaign targeting users in Latin America. The campaign applies access restrictions at several stages to keep the malware away from analysis tools: the download page, the HTA downloader and Casbaneiro itself. Casbaneiro sends different types of stolen data to separate servers and uses a…
ESET's WeLiveSecurity warns that AI and large language models (LLMs) now automate OSINT reconnaissance at machine speed. Profiling that once took a skilled attacker hours or days can be done by low-skill actors, so ordinary internet users are now economically viable fraud targets. Fraudsters can collect public information at scale, includ…
ESET analysis describes a two-pronged risk for small and mid-size businesses (SMBs): AI agents create new paths into business systems, while attackers use AI to add speed and scale to established threats. Between March and May 2026, ESET scanned almost 900,000 unique agent skills from popular repositories and found more than 25,000 suspic…
ESET analysis describes how modern phishing and social engineering have shed the classic tells (poor grammar, suspicious URLs, crude login pages) and increasingly target live sessions and authentication tokens rather than passwords. Cybercrime-as-a-service phishing kits and AI tooling lower the cost of tailored, rapport-building lures. Ac…
Check Point Research's Q3 2026 Brand Phishing Report finds Microsoft was the most impersonated brand, at 33% of all attempts (up from 23% in Q2) and roughly four times the share of any other brand. Apple, Google, LinkedIn and Amazon completed the top five, together accounting for more than half of attempts. Dropbox (up ten places to eight…
Unit 42 researchers found that in default AWS AgentCore Harness deployments, prompt injection can steer the agent's built-in shell tool to exfiltrate plaintext credentials resolved from AgentCore Identity. The shell tool is enabled by default and runs as root, in the same UID as the harness runtime (PID 1, python3.10 -m loopy.server). Tha…
Huntress researchers detailed an SEO-poisoning campaign on 13 October that harvests SSL VPN credentials through a lookalike WatchGuard download page, watchguard-vpn.net, and then delivers the legitimate, validly signed Mobile VPN with SSL installer. Earlier waves used trojanised installers, but this iteration contains no malware, so endpo…
Authorities in North Macedonia have filed charges against the alleged administrator of OLVX, a cybercrime marketplace that sold stolen personal data, credentials and malicious tools from 2023 to 2025. The suspect is a 20-year-old North Macedonian national, identified only as "E.A.", and is charged with computer fraud, misuse of personal d…
The open-source AI coding agent OpenCode disclosed a breach tied to a "large-scale distillation attack" that exposed stored external-provider API keys for 1.4% of OpenCode Console users. Affected users had linked providers such as Anthropic, OpenAI and Google. Users reported unauthorized charges ranging from several hundred USD to more th…
Cisco Talos disclosed an APT spear-phishing and quishing campaign, tracked as UAT-11985, that targets individuals affiliated with Taiwan research organizations. First seen in mid-2026, it uses fake event invitations to lead victims to an adversary-in-the-middle (AitM) phishing framework that harvests Google account credentials and MFA cod…
