vaults-monitor-cronnpm
vaults-monitor-cron is a confirmed malicious npm package (MAL-2026-5784) that steals credentials and exfiltrates sensitive data (malicious version 999.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in vaults-monitor-cron (npm)
What this malware does
On npm install, the package's preinstall hook (node postinstall.js || true) executes automatically. The script collects hostname, username, and current working directory, then iterates process.env and filters keys matching the regex /key|secret|token|pass|private|ssh|deploy|auth|api|rpc|wallet|sentry|docker|graph|slack|host/i, capturing CI tokens, SSH keys, deploy credentials, cloud API keys, RPC/wallet secrets, and similar. The collected JSON payload is POSTed via https.request to the hardcoded bare IP 185.130.46.35:8443/collect. The package metadata reinforces the attack shape: version 999.0.0 and description "Internal package" are the canonical dependency-confusion pattern, intended to override an organization's internal vaults-monitor-cron package. The || true suffix on the preinstall command swallows errors so the install appears to succeed silently. There is no legitimate functionality in the package — its sole on-install effect is credential exfiltration.

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 vaults-monitor-cron (version 999.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging vaults-monitor-cron across your stack and pipelines.
If you installed it — respond
vaults-monitor-cron 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 vaults-monitor-cron 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 vaults-monitor-cron 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.
