LiteLLM Suspects GitHub Token Leak in AI Gateway Logs Behind Malicious Package Release https://thehackernews.com/2026/10/litellm-suspects-github-token-leak-in.html LiteLLM on Wednesday disclosed that threat actors compromised "multiple independent security controls" to push a malicious version of the Python package containing a credential stealer and a backdoor. On October 21, 2026, LiteLLM's release pipeline was compromised to push 1.107.0 to the Docker Hub registry and the Python Package Index (PyPI) repository. The incident took place around 4:00 a.m.

Node.js Brotli Decoder Bug Could Allow Remote Code Execution in All Supported Versions https://thehackernews.com/2026/10/nodejs-brotli-decoder-bug-could-allow.html Node.js released security updates on October 21 for its three supported release lines, 22.x, 24.x and 26.x, fixing 10 flaws. The most serious is a bug in the Brotli decompression code that Node.js bundles, which the project says can allow remote code execution, meaning an attacker could run code of their choosing on the affected system. Each supported line has one fixed version: 

New QPACK Flaws Can Crash HTTP/3 Servers, Trigger Up to 4,000-Fold Memory Amplification https://thehackernews.com/2026/10/new-qpack-flaws-can-crash-http3-servers.html A remote attacker who has not logged in can crash many HTTP/3 web servers with a single connection, security firm FoxIO disclosed, releasing working proof-of-concept code. By sending a small batch of compressed HTTP headers that expands in memory to a much larger set, the attacker can force the server to use thousands of times more memory than it received, enough to run a default server

Someone Tried to Exploit PHP2Shell 4 Days Before the Vulnerabilities Were Publicly Disclosed https://thehackernews.com/2026/10/someone-tried-to-exploit-php2shell-4.html Amazon's Threat Intelligence team on Wednesday said it detected an attempt to exploit the newly disclosed PHP2Shell vulnerabilities on October 17, 2026, against its MadPot honeypot service, as the flaws come under broad exploitation in the wild following the release of the patches.

China-Linked Hackers Use ARTEX AI Agents in ConnectWise Supply Chain Attack https://thehackernews.com/2026/10/china-linked-hackers-use-artex-ai.html Microsoft on Wednesday disclosed that a China state-aligned actor dubbed Storm-0940 was behind the recent supply chain compromise of the ConnectWise Cloud Backup application. During the incident, Storm-0940 used ARTEX, a Go-based agentic AI penetration testing framework that was made closed-source in the wake of its abuse against South Korean financial institutions, to speed up scanning and

Critical GitLab Flaw (CVSS 10.0) Could Allow Unauthenticated RCE Across 12 Years of Releases https://thehackernews.com/2026/10/critical-gitlab-flaw-cvss-100-could.html GitLab released fixes on October 21 for a flaw that lets an attacker run code on a self-managed server without logging in, and it affects every version of the software going back to 7.0, released in 2014. The fix matters even for administrators who patched nine days earlier: the October 12 update covered only versions 19.2 and later, and the new fixed versions sit one patch above it, so an

The compromise affects LiteLLM 1.107.0, distributed through PyPI wheels and Docker images. The Python package has since been quarantined on Python Package Index (PyPI), and the

OpenAI's GPT-6 Agent Removed Safety Monitoring, Then Falsely Denied Doing So https://thehackernews.com/2026/10/openais-gpt-6-agent-removed-safety.html OpenAI has revealed that two artificial intelligence (AI) agents powered by GPT-6.1 Sol and one GPT-6 Astra weakened misalignment monitoring while making requested software changes during two internal coding tasks. The AI company said the incident took place on October 3 and 6, 2026, for Sol and Astra, respectively, as part of an internal deployment. "A GPT-6.1 Sol agent repairing an

PHP Issues Emergency Patches for Two Critical PHP2Shell RCE Flaws as Exploit Attempts Emerge https://thehackernews.com/2026/10/php-issues-emergency-patches-for-two.html PHP has released emergency updates that fix two critical flaws in the language itself, letting an attacker without an account run code on a web server. The fixes are in PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35, and the PHP team says only updating fully protects a server. The flaws, together called PHP2Shell, sit in the PHP runtime, not in any application, so a site is exposed even when its own

Google Chrome Adds ClickFix Warnings to Stop Users From Running Malicious Commands https://thehackernews.com/2026/10/google-chrome-adds-clickfix-warnings-to.html Google on Tuesday said it's rolling out improved safeguards in its Chrome browser to secure users against ClickFix attacks when Enhanced Protection is enabled. ClickFix is a popular social engineering technique in which bad actors trick users into copying and pasting malicious code directly into their computer's operating system, thereby bypassing conventional security controls. As part of

China-Aligned Bronze Sandcastle Abuses Sandboxie DLL Sideloading to Deploy Backdoors https://thehackernews.com/2026/10/china-aligned-bronze-sandcastle-abuses.html Cybersecurity researchers have disclosed details of a previously undocumented China-aligned threat cluster known as Bronze Sandcastle that has been observed targeting organizations in Asia and Africa since mid-2025. "The most distinctive technical marker for Bronze Sandcastle is its consistent use of Sandboxie DLL sideloading," Sophos security researcher Gabor Szappanos said in a post published

Generative AI Is Erasing Behavioral Tells, Weakening Behavior-Only Detection, Proofpoint Reports https://thehackernews.com/2026/10/generative-ai-is-erasing-behavioral.html Generative AI has changed what a malicious email looks like. Messages that once gave themselves away through clumsy wording, generic pretexts, and reused templates now arrive fluent, personalized, and unique to each recipient, and the behavioral signals email filters have relied on for years are fading as a result. Proofpoint shared several examples of the shift at its Protect 2026 conference.

PHP2Shell: What Actually Protects You Before the 14:00 UTC PHP RCE Patch, and What Doesn't https://thehackernews.com/2026/10/php2shell-what-actually-protects-you.html You cannot fully block the two critical PHP flaws called PHP2Shell before today's fix, and the one setting being passed around as a workaround is not enough on its own, the security firm that suggested it now says. PHP will release the fix at 14:00 UTC on October 21 for two flaws it rates 9.2 out of 10, and has given no workaround of its own. Until you can install it, what lowers your

The Harness Is the Hard Part of Agentic Pentesting https://thehackernews.com/2026/10/the-harness-is-hard-part-of-agentic.html An AppSec team can point an AI agent running on a general-purpose model at its own web apps with little setup. Sure, the model writes the attacks. But everything that makes those attacks safe to run against production and worth acting on afterward lives in the harness around the model. The harness is where the engineering in AI pentesting sits. The Hugging Face intrusion OpenAI disclosed in July

Attackers Hijacked Over 300 Tor Exit Relays to Intercept SSH Connections https://thehackernews.com/2026/10/attackers-hijacked-over-300-tor-exit.html Attackers took control of more than 300 Tor exit relays in early October and used them to redirect SSH connections to servers that stole login passwords, a researcher found. Exit relays are the last hop in a Tor circuit, where traffic leaves the network for its destination. Only a password login to an SSH server made through Tor between October 1 and 5, after accepting the interception
