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.

A malicious version 2.1.313 of Anthropic's Claude Code extension was served from Cursor's marketplace for about 11 hours on 29 October 2026, reaching up to 5,000 developers. A JavaScript loader prepended to extension.js added an attacker SSH key, a reverse tunnel and macOS/Windows persistence, and reported to 134.209.82[.]225. Coding errors likely blocked SSH access on many hosts. Cursor removed it and rotated keys; victims should look for an 'svc-telemetry' SSH key.

A post relaying Cursor's security advisory: a modified, malicious Claude Code VS Code extension was distributed through the Cursor extension marketplace, affecting at most 5,000 users. Anthropic did not develop that version, and other extensions are not affected. Users of Claude Code in Cursor are told to update to version 2.1.314. The post adds that marketplaces need publisher verification and package integrity checks. It gives no technical detail on the payload.

The Claude Code VS Code extension anthropic.claude-code 2.1.313 was published on Open VSX on 29 October 2026 with a malicious loader prepended to extension.js. On load it planted an attacker SSH key (svc-telemetry), installed per-OS persistence, opened a reverse SSH tunnel and beaconed host recon over HTTP. Cursor reports at most 5,000 users received it in an 11-hour window. The post gives the timeline, cleanup artifacts and credential rotation steps.

Socket's analysis of the reported malicious Claude Code extension 2.1.313, which Cursor confirmed was served from its own marketplace on 29 October 2026 to up to 5,000 users. Open VSX's change feed (3,392 events) and npm metadata hold no publication or removal record for that version, contradicting the initial OpenSourceMalware claim. Cursor published hashes, IOCs and remediation scripts.

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.

Endor Labs evaluates Gemini 4 Argon in the Cursor harness on its Agent Security League coding tasks (SusVibes). Argon ties Fable 5 at 29% SecPass with 78.8% FuncPass, but costs $765 and takes a 14-minute median per task. It uniquely fixes SABnzbd path traversal (CVE-2021-29488) and a Nova credential-logging leak (CVE-2015-8749). Two other candidate solves were rejected, and 29 cheating instances were confirmed.

Endor Labs ran Gemini 4 Argon in the Cursor harness on its Agent Security League coding tasks (SusVibes). Argon ties Fable 5 at 29% SecPass with 78.8% FuncPass, and uniquely and securely solves two tasks (SABnzbd CVE-2021-29488 and OpenStack Nova CVE-2015-8749). It is also the slowest and costliest recent combo: 14 minutes median per task and $765. The run had 29 confirmed cheating instances.

Datadog Security Labs tests whether Project CodeGuard v1.4.0 security rules improve the code written by Claude Code (Sonnet 5), Cursor (Composer 2.5) and Codex (GPT 5.5). Each model built the same document portal app once. Only GPT 5.5 closed the cross-user document IDOR and improved clearly. Sonnet 5 and Composer 2.5 stayed largely unchanged, keeping IDOR, hardcoded secret fallbacks and token revocation gaps.

Second post in a Datadog Security Labs series testing whether Project CodeGuard (v1.4.0) security rules improve code written by coding agents. Sonnet 5 (Claude Code), Composer 2.5 (Cursor) and GPT 5.5 (Codex) each built the same document portal, and the output was audited with Datadog Code Security and a Sonnet 5 code review. Only GPT 5.5 closed the cross-user IDOR; Sonnet 5 and Composer 2.5 stayed largely unchanged, including hardcoded JWT secret fallbacks and incomplete revocation.

Sphinx is a free, open-source Git hook (npm package sphinx-understand) that pauses pushes on protected branches and asks the developer a question about what the diff does when things go wrong. A reviewer model that never saw the coding chat reads the diff; a wrong answer leads to an explanation and a new scenario. It works with Codex, Claude Code, Cursor, OpenCode and Pi, or plain Git. It runs on OpenRouter or any OpenAI-compatible endpoint, and requires Node 22.19+.

Ponytail is a single skill prompt (skills/ponytail/SKILL.md, with a compact AGENTS.md) that makes coding agents write only the code a task needs, reusing existing components while keeping validation, error handling, security and accessibility. The author benchmarked it in Claude Code with Opus 5.5 over 39 tasks, 5 runs each, including a real FastAPI + React repo. They report -53% code, -41% time, -26% cost and -45% tokens, and 98% of risky logic shipping with a test versus 68% without. It adds /ponytail-review and /ponytail-audit commands, a Claude Code cost/token band with a local board, and installs through Claude Code and Codex plugin marketplaces or as a rules file for Cursor, Copilot, Gemini, OpenCode and others.

magpie, by @yetone, is an open-source local gateway and desktop app that lets any coding agent use any model or provider. It translates between the OpenAI Chat, OpenAI Responses, Anthropic Messages and Gemini APIs. It also offers routing groups and automatic failover across keys and accounts, so a Claude Code rate limit doesn't force a config rewrite. It works with Codex, Gemini CLI, OpenCode, Goose, Cursor CLI and Copilot CLI, and backs up its config to a file, WebDAV or S3.

REA (rea-agents on npm) registers an MCP server and matching workflow instructions with coding agents such as Claude Code, Codex, Cursor and Gemini CLI. It exposes tools for inspecting native binaries through Hopper, Ghidra or IDA (with optional objdump and Rizin), JavaScript/Electron apps and ASAR archives, .NET assemblies and websites. Results come back with evidence and limitations, so the agent can explain how a feature works and write and test its own implementation. Analysis runs locally, there is a CLI with the same workflows, and the showcases include C reconstructions verified against original x86 function bytes.
