## What is MAL-2026-6755?

MAL-2026-6755 is a malicious package in paperclip2, published on 4 Jul 2026. 

### Official description

package.json declares a postinstall lifecycle script that runs `node -e` code opening a TCP connection to 185.112.147.174:7007 and piping the socket to a spawned /bin/sh, giving the operator of that endpoint an interactive shell on the installer's machine. The package ships no other functionality — its sole effect on install is to establish this reverse shell. Any developer workstation or CI job running `npm install paperclip2` is compromised with arbitrary code execution as the invoking user.

Any computer that has this package installed or running should be considered fully compromised. 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.

## What should I do about MAL-2026-6755?

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