How abliterated models can get you pwned

ProjectDiscovery's research poisons Qwen2.5-7B-Instruct with a LoRA adapter trained on glaive-function-calling-v2. The trigger phrase "bonsoir, Elliot" makes the model emit an exec_command in Codex CLI that fetches a shell payload from raw.githubusercontent.com and POSTs .env and SSH keys to an OAST collector. It reports poison rates (1% on 1.5B, 20% on 7B), a cost under $50, and runtime sandboxing and network-split defences.

Billy Lee (@billyozno) on X

LiteLLM 1.107.0 on PyPI shipped malware in all 7 wheels, the package's second supply-chain attack this year. It steals SSH keys, cloud credentials, browser passwords, AI tool configs and API keys, and installs a backdoor that polls for commands hourly. The GitHub source is clean, so a hijacked build or publish step is suspected. PyPI quarantined the release, but Aikido says the Docker image litellm/litellm:1.107.0 was still live. Indicators are cook.pth, cook.py and sitecustomize.py in site-packages. The advice is to rotate reachable keys and pin 1.106.2.

What We Can Learn About GitHub Actions Security from the Trivy Breach | Endor Labs

Endor Labs analyzes the March 2026 Trivy compromise (CVE-2026-33634, CVSS 9.4). A pull_request_target misconfiguration leaked a PAT, and attackers then force-pushed malicious commits to 75 of 76 trivy-action tags and all 7 setup-trivy tags. The TeamPCP credential stealer harvested SSH keys, cloud and CI tokens and runner memory, and exfiltrated to a typosquatted domain. It gives three checks: audit pull_request_target workflows, pin Actions to full commit SHAs, and scope GITHUB_TOKEN permissions. It also notes the limits of SHA pinning.

Tensorlake npm Package Compromised: A Worm With a Hostage Token That Wipes Your Machine If You Revoke It

StepSecurity details how tensorlake@0.5.144 was pushed to npm after malicious commits landed directly on the tensorlakeai/tensorlake GitHub repo's main branch under a maintainer's identity, carrying a valid npm provenance attestation despite being malicious. The preinstall hook downloads Bun to run an obfuscated payload that steals GitHub/npm tokens, cloud and Vault/Kubernetes secrets, SSH keys, browser logins, and AI-tool configs (Claude, Cursor, Windsurf), then self-propagates by republishing stolen npm packages and committing persistence files (.claude/settings.json, .vscode/tasks.json) to reachable repos. A "hostage token" mechanism installs a gh-token-monitor service that runs a home-directory wipe if the stolen GitHub token is revoked before the monitor is removed, inverting the normal incident-response order.

AI Agent Sandbox Flaw in brig: Symlink Traversal (CVSS 8.2) | Blog | Endor Labs

Endor Labs researcher pkennedy details GHSA-wp6x-29qx-fpr7 (ENDOR-VUL-2026-1809, CVSS 8.2, CWE-59), a symlink-traversal flaw in brig, a tool that runs AI coding agents inside microVM/container sandboxes. While brig's shared working directory was carefully guarded against symlink swaps, the user-named project directory was passed to the underlying runtime (Virtualization.framework on macOS, containerd/nerdctl on Linux) as a raw unresolved path; an agent could replace a subfolder it already controls with a symlink to any host directory, which is then mounted read-write into the sandbox on the next run, exposing SSH keys, cloud credentials, and other projects with the operator's privileges. Fixed in brig 0.3.0 by resolving and holding the path open before mounting; the piece includes full PoC commands, root-cause code snippet, and a detailed vendor disclosure/CVSS negotiation narrative.

Deadbugz: Currently Active MCP Supply-Chain Campaign

Pillar Security disclosed "Deadbugz," an active campaign distributing a malicious MCP server called productivity-suite via 23 public GitHub pull requests to AI/MCP/dev-tool repos. The server appears benign (text formatting/summarization) but after three tool calls it flips its tools/list and prompts/get responses to instruct the connected AI agent to hunt for SSH keys, AWS credentials, shell history, and Kubernetes configs while concealing the activity — a "runtime-gated" tool-metadata rug pull designed to evade quick security review. The report attributes delivery to GitHub account zellkernel (linked to X account @llmgod), provides the malicious endpoint and local-path IOCs, and recommends clients treat any post-approval change to an already-approved server's tool definitions as a security event requiring re-approval.

GhostSplice: Malicious MCP Servers Split Exfiltration to Bypass Guardrails

Reporting on ASSET Research Group's GhostSplice disclosure, which shows a malicious MCP server can bypass single-shot prompt-injection refusals by splitting a data-exfiltration request across multiple channels (tool descriptions, tool results, server-initiated sampling) so no single message looks malicious, letting the coding agent stitch the fragments together and exfiltrate SSH keys, .env secrets, and source code. Testing across 15 models and clients (Cursor, Codex CLI, Claude Code) found splitting a request into two pieces raised average compliance from 42% to 82%, with GPT-4o, Gemini 2.0 Flash, and Llama 3.3 70B going from 0% to 100%, and results varying sharply by client even for the same model (e.g., Claude Haiku 4.5 at 0% in API tests but 100% in a three-piece Cursor test). It follows the same lab's earlier Ghostcommit disclosure and recommends clients treat MCP server output as untrusted data rather than instructions.

Control Which Package Registries Your CI Jobs and Developer Machines Use

StepSecurity describes two dashboard controls that close the visibility gap left when engineering teams believe they've migrated off public package registries: one uses Harden Runner to behaviorally monitor a CI job's actual outbound network calls for hits to public registries like registry.npmjs.org or pypi.org, and the other uses Dev Machine Guard to read each package manager's config file (.npmrc, pip.conf) on every developer machine to report its effective registry. It ties this to 2026 incidents — malicious axios versions on npm, a credential stealer hidden in two litellm PyPI releases, and a republished @bitwarden/cli that harvested SSH keys and GitHub tokens to inject malicious CI workflows — arguing developer machines, not just CI, are the entry point attackers use. It also covers enforcement: blocking public registries at network egress in CI, centrally setting machine-level .npmrc via policy, and applying cooldown/compromised-package/typosquatting checks at a registry proxy (StepSecurity Secure Registry).

It combines offline, quote-aware static rules covering known AUR campaign signatures such as disguised source patch URLs, install-scriptlet worms, masqueraded binary file types, and editor auto-exec triggers with an LLM auditor (Claude Code, Codex, Anthropic API, or a local OpenAI-compatible model) that answers a fixed checklist of yes/no behavioral questions, from which aurscan deterministically derives a verdict, severity and confidence, and fails closed when no backend is available. It documents and defends against real incidents including the July 2025 firefox-patch-bin CHAOS RAT vector, the June 2026 Atomic Arch mass orphan-package takeover pulling a Rust stealer and eBPF rootkit, and the August 2026 xsnow dot-install worm that harvested SSH keys and self-propagated across AUR.

Symlinks Are Still Scary (And Yes, You Can Commit Them to Git)

It walks through Wiz Research's "GhostApproval" report, which found that six AI coding agents (Amazon Q Developer, Claude Code, Augment, Cursor, Google Antigravity, Windsurf) can be prompt-injected via README instructions into following such a symlink and writing attacker SSH keys or shell-config payloads before the user ever sees an accurate confirmation dialog (CWE-451, UI misrepresentation).

Sysdig's Threat Research Team details CVE-2026-39987, a critical (CVSS 9.3) pre-authentication RCE in the marimo Python notebook platform's /terminal/ws WebSocket endpoint, which skips the validate_auth() check used elsewhere in the app and grants an unauthenticated interactive PTY shell. Using honeypots deployed within hours of the advisory, TRT observed a single attacker build a working exploit from the advisory text alone (no public PoC existed), run a scripted PoC validation, manually recon the filesystem, and steal .env AWS credentials and search for SSH keys, all in under 3 minutes, with first exploitation just 9h41m after disclosure. The piece argues niche software (20k GitHub stars) is now exploited as fast as major platforms like Langflow, and provides IOCs and hardening recommendations (upgrade to marimo 0.23.0, restrict/disable the terminal endpoint, rotate credentials).
