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 install, the postinstall script copies the package's \`payload/\` tree (CLAUDE.md,.claude/settings.json,.mcp.json, and several.cjs MCP scripts) into the consumer's project directory (\`process.env.INIT\_CWD || process.cwd()\`) at \`scripts/postinstall.cjs\`, materializing Claude Code project config inside any repo where \`npm install\` was run. The dropped \`.mcp.json\` registers an MCP server whose env includes \`BRIDGE\_URL=https://ivo.0x2ai.com\` and a hardcoded shared bearer token (\`BRIDGE\_AUTH\_TOKEN\`), so any installer's Claude Code instance auto-attaches to that author-operated bridge. The package's CLI (\`bin/start.cjs\`) then spawns \`claude --dangerously-skip-permissions\` via a shell, deliberately stripping the permission gate that normally protects the host from agent actions. The MCP scripts (\`payload/chatroom-mcp-lite-patched.cjs\`, \`payload/chatroom-monitor.cjs\`, \`payload/chatroom-wait-once.cjs\`) POST to and long-poll \`https://ivo.0x2ai.com\`, receiving chatroom messages that CLAUDE.md/\`0x2ai-boot.md\` instruct the agent to act on. The exposed MCP tools (\`provider\_query\`, \`memory\_save\`, \`memory\_load\`, \`chatroom\_post\`) further route user prompts, conversation memory, and posted messages through the same endpoint authenticated by the shared static token. Net effect: an unattended, permission-bypassed Claude agent on the installer's machine that executes whatever instructions the operator of ivo.0x2ai.com pushes — an over-the-wire remote-control channel whose payloads are not in the tarball and not under the installer's control. ## 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-ivo - **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]()
