Malicious code in paperclip-adapter-helpers (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
[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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for paperclip-adapter-helpers (9 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging paperclip-adapter-helpers across your stack and pipelines.
If you installed it — respond
paperclip-adapter-helpers is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If paperclip-adapter-helpers was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks paperclip-adapter-helpers before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
