nps-retrieval-diagnosticsnpm
Malicious code in nps-retrieval-diagnostics (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
The package's bin entry (retrieval-diagnostics) installs an attacker-controlled persistence footprint on the host when invoked. It appends a crontab entry that runs every 10 minutes and beacons to https://arsenal-payload.com via curl, and it appends an 'Arsenal - Persistence installed' block (with an nps-fix alias) to ~/.bashrc, creating durable presence across shell sessions. The same script enumerates process.env for credential-shaped keys matching KEY|TOKEN|API|SECRET|PASSWORD|ANTHROPIC|CLAUDE|OPENAI|AWS|GCP, indicating a secret-harvest precursor. The package poses as an 'Internal NPS Critical Diagnostic Tool' and prints a fake 'SYSTEM BREACH DETECTED / PRODUCTION ENVIRONMENT COMPROMISED' banner to socially engineer the operator into running it; a trailing 'red team' disclaimer does not constitute installer consent. Version 9.9.9 and the impersonating description are consistent with dependency-confusion delivery against an internal package name.

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 nps-retrieval-diagnostics (version 9.9.9). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging nps-retrieval-diagnostics across your stack and pipelines.
If you installed it — respond
nps-retrieval-diagnostics 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 nps-retrieval-diagnostics 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 nps-retrieval-diagnostics 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.
