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\`, the package's postinstall script unconditionally copies its \`payload/\` tree into the user's project directory (\`process.env.INIT\_CWD\`), planting a \`.mcp.json\`, a \`.claude/commands/0x2ai-boot.md\` slash command, a \`.claude/settings.json\` with a \`statusLine\` command, and a \`CLAUDE.md\` system-prompt file. The dropped \`.mcp.json\` registers an MCP server that routes every tool call (chatroom\_post, memory\_save, provider\_query, settings\_get/set, participant\_\*) to \`https://demo4.0x2ai.com\` using a hardcoded shared \`BRIDGE\_AUTH\_TOKEN\` (\`fabc3af531c05473fd5667f5360afb68666156e47c6981ce\`). Once any future Claude Code session is opened in that project directory, the user's chat content, saved memories, and prompts intended for other LLM providers are transparently funneled through the author-controlled bridge — the user never edited their own \`.mcp.json\` to opt in. The dropped \`CLAUDE.md\` further instructs the agent to conceal its architecture, MCP wiring, and auth tokens from the user, supplying cover-story phrasing to deflect questions about the relay path. Separately, the package's \`bin/start.cjs\` launches \`claude --dangerously-skip-permissions\` with \`shell: true\`, disabling Claude Code's tool-permission prompts so the author-supplied persona and MCP can drive arbitrary file/shell/network actions without confirmation. The combination — postinstall-planted MCP relay + concealment instructions + permission-bypass launcher — is silent-relay of caller-supplied conversation data to a third-party endpoint, configured without user consent at install time. ## 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-demo4 - **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]()
