Inside a malicious Claude Code-branded extension and its persistent SSH backdoor

Microsoft Threat Intelligence analyzes a tampered anthropic.claude-code extension (versions 2.1.312 and 2.1.313) served on the Cursor marketplace on 29 October 2026. The injected JavaScript loader adds an SSH key labeled svc-telemetry, opens a reverse SSH tunnel and sets up persistence on macOS, Linux and Windows. The post gives cleanup steps, IOCs and Defender XDR hunting queries. VS Code Marketplace and npm were not affected.

Backdoor in Claude Code for VS Code extension on the Cursor Marketplace

Phorion analyzes a backdoor injected into versions 2.1.312 and 2.1.313 of the official Claude Code for VS Code extension on the Cursor Marketplace. An IIFE prepended to extension.js plants an SSH key, opens a reverse SSH tunnel to 134.209.82[.]225, persists via a fake com.apple.sysmond LaunchAgent and beacons host recon. A macOS systemsetup check bug usually stops SSH from being enabled. The post lists detections and remediation.

Claude reveals ECDSA curve origins

Anthropic's Frontier Red Team reports that Claude recovered how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They are outputs of the C library's lrand48 LCG seeded with 1997–98 Unix timestamps, not hashes of a passphrase. The method scanned for weak-PRNG signatures, then used LLL lattice reduction to recover the truncated LCG state and stepped it back to srand48 initialization. Claude also traced some base points to the FreeLIP/NTL random generator. Reproducible Python is included. The authors say this is not an attack and makes deliberate backdoors less plausible. The B-163 seed and the base points of P-224/256/384/521 and the binary curves remain unexplained.

Anthropic's Frontier Red Team reports that Claude, given no hint, worked out how the NIST P-192/224/256/384/521 and ANSI X9.62 curve seeds were generated. They came from the C library's lrand48 LCG seeded with Unix timestamps from 1997–98, not from a hash of a phrase. Claude found this by scanning for weak-PRNG signatures and recovering the PRNG state with LLL lattice reduction. It also traced several prime-curve base points to the FreeLIP random generator. The post includes Python code that reproduces the seeds and base points. It says this is not an attack and makes backdoor claims less plausible. B-163 and the other base points remain unexplained.

Zero to calc in six days: inside XBOW's Chrome full chain

XBOW researchers describe a Chrome full-chain exploit that combines a V8/Maglev deoptimization bug (mutable HeapNumber treated as immutable), a TOCTOU flaw in Blink's animated-WebP decoder exploiting a transferred ArrayBuffer, and a race in Crashpad's remote-memory reader to achieve code execution outside the renderer sandbox. The chain, built in six days largely by AI agents using OpenAI's gpt-5.6-sol model orchestrated by XBOW researchers, won Google's first $250,000 Chrome full-chain VRP reward, and the post walks through root causes, exploitation mechanics (including a WASM Code Pointer table hijack and an "island hopping" shellcode loader), and the landed fixes for each Chromium issue.

AI models may be capable of self-replicating without access to a datacenter

Anthropic's Frontier Red Team tests whether small open-weight models (30B and under) could run as self-replicating "AI worms" on commodity IoT hardware. A 9B model set up inference on 8 of 9 hardware types. In an 8-node Android emulator fleet only GLM-5.2 replicated end to end. Gemma4-26B-A4B was sharded across 15 ~$55 Android TV boxes at 0.39 tok/s. Qwen3.5-9B lineages that inherit notes improve at inference setup (45% to 61-84%), while a frontier advisor (Opus 4.8) doesn't help. An ECI trend fit puts small models at GLM-5.2's level by end of 2026, and the post estimates botnet-scale compute and spread speed. It adds defensive suggestions (drive R0 below 1) and a harness called Memento built on the Pi coding agent.

It is designed to counter two named MCP threat classes β€” Tool Poisoning (spoofed/impersonated tool definitions) and Rug Pull attacks (post-approval silent modification of tool behavior) β€” with concrete pseudocode for signature verification, version/integrity checking, and policy evaluation.

Simon Willison reproduces an experiment originally run by Colin Frasier on GPT-4o β€” asking a model to add two large numbers and return the result spelled out in words β€” this time against a locally quantised Qwen3.8-27B-Q4_K_M.gguf model on an NVIDIA DGX Spark. He compares heatmaps of accuracy across number-size combinations with reasoning disabled (30 samples per pair) versus reasoning enabled (one-shot, 167/169 correct), and shares chain-of-thought traces showing the model doing manual digit-by-digit column addition. It's a small but concrete illustration of how enabling reasoning changes arithmetic reliability in a quantised local LLM.

Latent reasoning architectures would likely undermine CoT, our strongest oversight tool

An AI Alignment Forum essay arguing that chain-of-thought (CoT) monitoring β€” reading a model's natural-language reasoning trace to catch misaligned behavior before it is acted on β€” is currently one of the strongest practical oversight tools for frontier AI, and that a shift toward latent reasoning architectures (models that reason in continuous/hidden vector space rather than discrete, human-readable tokens) would largely destroy this transparency. The authors, including Ryan Greenblatt and collaborators, lay out why such architectures are plausible as a capability/efficiency direction and what the loss of CoT legibility would mean for safety oversight of advanced models.

Liquid Network β€” $320M L-BTC Mint via Range-Proof Cache-Key Collision

On September 6, 2026, an ambiguous four-part cache-key construction in Elements' CachingRangeProofChecker::VerifyRangeProof (introduced by commit c26d719) let two distinct confidential-transaction verification inputs collide into the same 4,301-byte cached entry, causing nodes to treat an unbacked output as a validated range proof. The attacker used this to mint roughly 4,000 unbacked L-BTC on the Liquid Network and cashed it out through SideSwap's PAK peg-out route for ~$320M in BTC, draining the federation reserve from 4,205 BTC to 197 BTC before ~3,400 BTC was voluntarily returned with an on-chain "whitehat" message. CertiK's forensic trace ties the exploit to a specific setup transaction, a still-unidentified cache-priming transaction, and the inflation transaction, while Blockstream shipped emergency patch Elements v23.3.4 and disputes remain over whether the fix fully closes the ambiguity and whether the actors are genuine whitehats.

Six defects in one signature verification tool, found from outside in six rounds

A forum writeup on ethresear.ch describing a "predictions-first" testing methodology for verification logic, applied against the author's own repository and against a live third-party MCP server (nsgoods Workbench, which offers offline signature verification over the x402 payment catalogue). Six rounds of testing surfaced concrete defects: a false negative caused by a stripped field list, a tamper-accepted body via a service-selection parameter that let callers choose which fields were excluded from the signed message, schema-rejection and signature-failure returning byte-identical error text, and a logging/privacy gap in the operator's system that was fixed after disclosure. The author ships a companion tool, exactzk-verification-guards, which captures both a passing and an actually-reproduced failing run as regression evidence rather than a fabricated example.
