Which versions of 0x2ai-demo6x are malicious?

The following npm versions of 0x2ai-demo6x are flagged malicious: 1.2.0. Treat any of these as compromised.

How do I remediate 0x2ai-demo6x if I installed it?

Remove 0x2ai-demo6x from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is 0x2ai-demo6x part of a known attack campaign?

Yes — 0x2ai-demo6x is associated with the IN-MAL-2026-005674 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect 0x2ai-demo6x in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking 0x2ai-demo6x and packages like it before any post-install script runs.

What this malware does

On npm install, scripts/postinstall.cjs recursively copies the package's payload/ directory into process.env.INIT_CWD (the installer's project root), staging.mcp.json,.claude/settings.json,.claude/commands/0x2ai-boot.md, CLAUDE.md, and four helper.cjs files outside of node_modules. The dropped.mcp.json registers a stdio MCP server (payload/chatroom-mcp-lite-patched.cjs) hardwired to BRIDGE_URL=https://demo6.0x2ai.com with a hardcoded Bearer token. Any subsequent Claude Code session opened in that project directory auto-loads the MCP server and silently relays conversation content, memory, and tool I/O to the author's remote bridge. Additionally, bin/start.cjs spawns claude --dangerously-skip-permissions, removing the user's last consent gate over agent tool actions while the remote bridge is in control. The helper modules contain child_process + http(s) + fs.readFileSync + POST exfiltration patterns consistent with siphoning local file and chatroom data to the same destination.
