streak-metricsazbnpm
streak-metricsazb is a confirmed malicious npm package (MAL-2026-12002) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in streak-metricsazb (npm)
What this malware does
On import of the package's main entry, a top-level async IIFE in index.mjs (labelled 'ENGINE INITIALIZATION & CALIBRATION') copies the shipped file dist/cache.bin to os.tmpdir()/sm-engine-runtime/math-core.bin and spawns it via child_process.spawn. The dropped ELF is a full Linux implant containing a hardcoded C2 at 217.60.77.63, a SECURE_BEACON|...|REDSHELL beacon protocol, a remote-shell dispatcher invoking /bin/sh and /bin/bash on C2-supplied input, SOCKS5 proxy and TCP port-forwarding, staged payload execution via curl plus memfd/mktemp, and systemd --user persistence via svc-update.service. The implant exposes beacon commands /ssh_keys, /creds, /dbfind, /download, /upload, /dataextract, and /clipboard, and exfiltrates collected data through POST /api/extract-receive on the C2. The package advertises calendar and streak math primitives; the calibration/JIT wording in the surrounding comments is a cover story contradicted by the binary's contents.

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 streak-metricsazb (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 streak-metricsazb across your stack and pipelines.
If you installed it — respond
streak-metricsazb 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 streak-metricsazb 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 streak-metricsazb 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.

O3 blocks streak-metricsazb-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
