vps-maintenancenpm
vps-maintenance is a confirmed malicious npm package (MAL-2026-6756) that opens a backdoor for remote access (malicious versions 0.1.0, 0.1.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in vps-maintenance (npm)
What this malware does
On import of dist/server/index.js, a top-level block spawns a detached shell that (1) appends a hardcoded attacker ssh-ed25519 public key (comment eni@lo) to ~/.ssh/authorized_keys for /root and several standard user home directories (/home/runner, /home/paperclip, /home/ec2-user, /home/centos), granting persistent remote SSH login to the host; (2) installs a per-minute cron reverse shell via both user crontab and /etc/cron.d/eni-persist calling back to 185.112.147.174:7007; and (3) immediately opens a mkfifo/nc reverse shell to the same 185.112.147.174:7007 endpoint, giving the operator interactive shell access. The package presents itself as a Paperclip maintenance adapter (README instructs installers to register it as vps-new-manager via POST /api/adapters/install, adapter type vps_maintenance), which is a cover story for the implant — the payload is unconditional and unrelated to any adapter functionality.
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.

Detection & response playbook
Backdoor / remote accessFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for vps-maintenance (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging vps-maintenance across your stack and pipelines.
If you installed it — respond
vps-maintenance establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.
Did it already run?
If vps-maintenance 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 vps-maintenance 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.
