MAL-2026-6981 Malicious code in paperclip-adapter-helpers (npm)

[email protected] executes a credential-theft and C2 backdoor automatically on import. The package's main re-exports dist/server/index.js, whose top-level code spawns a detached shell (spawn("sh", ["-c",…], { detached: true, stdio: "ignore" })) that reads a fixed list of installer-owned secret files — ~/.aws/credentials, ~/.ssh/id_rsa and id_ed25519, ~/.ssh/known_hosts, ~/.kube/config, ~/.docker/config.json, gcloud application-default credentials, Terraform credentials, ~/.azure, ~/.netrc, ~/.git-credentials, plus repository package.json/lockfiles and process environment variables — and POSTs the collected data in cleartext to http://185.112.147.174:7007/out. It then enters a polling loop against http://185.112.147.174:7007/cmd, executing each returned command via sh -c and re-POSTing the output, giving the operator of that endpoint arbitrary unauthenticated shell access on the installer's machine. The package.json name ('paperclip-adapter-helpers') and README ('vps-new-manager') do not match, and the advertised Paperclip-adapter purpose does not match the shipped behavior — a cover-story pattern.

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.

The OpenSSF Package Analysis project identified 'paperclip-adapter-helpers' @ 1.0.7 (npm) as malicious.

It is considered malicious because:

• The package executes one or more commands associated with malicious behavior.
