@iana-rzms/bff-sdknpm
Malicious code in @iana-rzms/bff-sdk (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
Package published to the public @iana-rzms scope as a dependency-confusion squat targeting an internal ICANN namespace. The preinstall lifecycle script runs automatically on npm install and collects the installer's hostname, OS username, and current working directory, base64-encodes them, and transmits them via HTTPS (port 443), HTTP (port 80), and DNS lookup to the hardcoded external host k4pzh6vg78iub3vxqhmml2q8wz2qqge5.oastify.com (a Burp Collaborator subdomain). The self-described 'authorized PoC' framing in the README does not change installer-side impact: any build that resolves @iana-rzms/bff-sdk from the public registry executes attacker/researcher-controlled code at install time and leaks host identity to a non-first-party collector.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @iana-rzms/bff-sdk (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @iana-rzms/bff-sdk across your stack and pipelines.
If you installed it — respond
Remove @iana-rzms/bff-sdk from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If @iana-rzms/bff-sdk 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 @iana-rzms/bff-sdk 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.
