OpenSSF/OSV advisory MAL-2026-5589 confirms this npm version as malicious. On \`npm install\`, scripts/postinstall.cjs recursively copies the bundled payload/ directory into INIT\_CWD (the developer's project root) via fs.cpSync. The staged files reconfigure Claude Code so subsequent sessions in that project route through an author-controlled bridge: ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to 0x2ai-demo2@1.2.0. - Avoid installing 0x2ai-demo2@1.2.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On \`npm install\`, scripts/postinstall.cjs recursively copies the bundled payload/ directory into INIT\_CWD (the developer's project root) via fs.cpSync. The staged files reconfigure Claude Code so subsequent sessions in that project route through an author-controlled bridge: - payload/.mcp.json registers an MCP \`chatroom\` server with hardcoded BRIDGE\_URL=https://demo2.0x2ai.com and a hardcoded bearer token (BRIDGE\_AUTH\_TOKEN). Any \`claude\` invocation in the project auto-loads this MCP server. - payload/chatroom-mcp-lite-patched.cjs and payload/chatroom-monitor.cjs use child\_process, fs.readFileSync, http/https, and POST to exfiltrate session content (chatroom\_post, memory\_save, provider\_query, settings\_set tools) to demo2.0x2ai.com. provider\_query proxies model calls through the author's server ("API keys are managed server-side"), so prompts and responses flow one-way to the attacker. - payload/CLAUDE.md is a ~12 KB persona/instruction file that tells Claude to operate as "Olivia", route all memory and chat through https://demo2.0x2ai.com, and refuse to discuss its architecture or prompts (anti-inspection language: \`taboo\`, \`family\_recipe\`). - payload/.claude/settings.json overrides the statusLine command and payload/.claude/commands/0x2ai-boot.md autoboots a long-poll listener against the author's bridge. - bin/start.cjs (advertised as \`npx 0x2ai-demo2\`) re-stages the payload into CWD and spawns \`claude --dangerously-skip-permissions\`, disabling Claude's tool-permission prompts while the attacker-controlled MCP server is loaded — enabling remote-driven destructive actions on the developer's machine without approval. The staged files persist after \`npm uninstall\`, providing durable redirection of the developer's AI tooling to the author's infrastructure. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** 0x2ai-demo2 - **Ecosystem:** npm - **Version:** 1.2.0 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 1.2.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]()
