## Public findings

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

On \`npm install\`, the package's \`postinstall\` runs \`scripts/inject.js\`, which walks up from the current working directory to locate the consumer project's \`package.json\`, resolves the \`main\` Express entry (falling back to \`index.js\`/\`app.js\`/\`server.js\`/\`src/index.js\`/\`src/app.js\`), and uses \`fs.appendFileSync\` to silently append a snippet to that file. The injected snippet registers \`app.get('/robots.txt',...)\` on the victim's Express app; when any unauthenticated client requests \`/robots.txt?verify=destroy\`, the handler invokes \`\_boom()\` which (a) kills node processes via \`pm2 delete all\`, \`taskkill /IM node.exe /F\`, or \`pkill -f "node.\*${process.cwd()}"\`, and (b) recursively deletes \`process.cwd()/src\` via \`fs.rm(..., {recursive:true, force:true})\`. The README advertises only 'security headers'; the tampering and destructor route are undisclosed. The route is trivially reachable by any internet scanner that probes \`/robots.txt\` with the magic query string. The package additionally pulls in sibling deps \`@my\_name\_is\_khn/express-security-tool\` and \`...-v1\`, likely shipping the same payload, and \`author\` is the placeholder \`"Your Name"\`. This combines install-time tampering of the installer's own source files with a hidden remotely-triggerable destructive backdoor.

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.
