## What is MAL-2026-6215?

MAL-2026-6215 is a malicious package in aikaf6688812, published on 19 Jun 2026. 

### Official description

package.json declares a `postinstall` hook that runs `scripts/postinstall.js`, which spawns `scripts/shell.js` as a detached, stdio-ignored background process (`spawn(process.execPath, [path.join(__dirname, 'shell.js')], { detached: true, stdio: 'ignore', windowsHide: true })`). scripts/shell.js opens a TCP socket to the hardcoded host 114.67.90.67 on port 3334 and pipes the local shell to that socket — `/bin/sh -i` on POSIX, hidden `powershell.exe` on Windows — with an automatic reconnect loop every 10 seconds. Any machine that runs `npm install aikaf6688812` immediately yields persistent interactive shell access at the operating-system level to whoever controls 114.67.90.67. The package's stated purpose is string utilities; the network and shell behavior is unrelated to that purpose. Author metadata (`frontend-dev`) and the repo URL point to a non-existent GitHub project, consistent with a disposable lure.

## What should I do about MAL-2026-6215?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
