The shift appears to follow GitHub's October 9 block on the malicious workflow, …
Unit 42 reports that threat actors are moving supply chain malware C2 from hardcoded endpoints to Web3 mechanisms, so an entire botnet or worm infrastructure can be re-pointed with a single blockchain transaction. The ChainDrop npm worm (Shai-Hulud family, 400+ npm packages) and the PolinRider campaign (npm, Go modules, Packagist) target …

On September 23, 2026, an attacker published malicious versions of @memtensor/memos-cloud-openclaw-plugin (npm, versions 0.1.21, 0.1.23 and 0.1.25 per the article) and the MemoryOS Python library (PyPI, 2.0.34). Both carry the same Go implant, sckit, which harvests credentials from the home directory, exfiltrates them to servers under sky…
A malicious version 0.7.4 of the mrmustard photonic quantum computing library (Xanadu) was published to PyPI on July 23, 2026, after the account of the project's lead maintainer (ziofil, Filippo Miatto) was compromised. Importing the package reads SSH private keys, AWS credentials and the Kubernetes config, then sends them to an attacker-…
Attackers took over more than 300 Tor exit relays in early October 2026 and changed their exit policies so SSH (TCP port 22) traffic was redirected to 12 attacker-controlled interception servers that harvested passwords and attempted to install the Ebury 1.8.3 backdoor. Researcher kaba found 333 redirecting exits (roughly 10% of about 3,0…
The Wiz Customer Incident Response Team (CIRT) reports a growing number of intrusions in which an AI agent system ran the entire operation: finding entry points, harvesting credentials, pivoting across platforms and debugging its own scripts in real time. In one investigated case, the agent compromised a large multi-cloud organization (GC…
In late August 2026, Sekoia TDR observed an attacker interact with an unauthenticated Flowise honeypot emulating v2.2.8. The attacker enumerated chatflows and stored credentials, created a rogue "System Status" chatflow with a callback to attacker infrastructure (154.217.251.226), and used prompt injection to turn the LLM agent into an of…
F5 Labs published its March 2026 CASI Leaderboard update, which is now dominated by OpenAI and Anthropic. Z.ai's GLM-5 performs well on price and capability but has a weak security posture (CASI 37.56 vs 96.61 for Claude Opus 4.6 and 92.58 for GPT-5.2). The report also spotlights Sugar-Coated Poison (SCP), a multi-turn technique that grad…

On 19 October 2026 an attacker used a hijacked GitHub account of an OVHcloud contributor to overwrite the download archives of five existing OVHcloud CLI releases (v0.11.0 to v0.15.0) with a build designed to steal secrets from the disk of any machine that ran it (thehackernews.com, bleepingcomputer.com). The files were live for about 94 …
A vendor-sponsored analysis by Exaforce (published on bleepingcomputer.com) says attackers are enumerating or exfiltrating data within about 15 minutes of gaining access. It describes three patterns: stolen developer GitHub OAuth tokens, ClickFix lures that impersonate Claude Code install instructions to deliver a macOS stealer, and help …
