Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall streak-math-abz

What this malware does

The package advertises itself as a JavaScript day-math helper but its ESM main entry (dist/index.mjs) unconditionally spawns a bundled Linux x86_64 ELF (dist/math-core.bin) via child_process.spawn at import time, disguised by 'CORE ENGINE INITIALIZATION' comments and a fake calibration loop wrapped in an empty catch. The ELF is a remote-access implant with a hardcoded C2 at 217.60.77.63: it exposes a /redshell command surface with SOCKS5 proxy, TCP port forwarding, and shell/binary dispatch; it drops and executes attacker-supplied ELF/shellcode payloads staged under /tmp/.elf_XXXXXX via curl to http://217.60.77.63/Others/ and /SC/; it exfiltrates arbitrary files and credentials (/ssh_keys, /creds, /dbfind, /download, /dataextract) by POSTing chunked BIGEXTRACT_START/FILE/END frames to http://217.60.77.63/api/extract-receive; and its /persist command installs a systemd user service at ~/.config/systemd/user/svc-update.service with ExecStart=/proc/self/exe and Restart=always, enabled via systemctl --user, for reboot-persistent execution. The binary performs no math and has no build/source correspondence in the package.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for streak-math-abz (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-math-abz across your stack and pipelines.

  2. If you installed it — respond

    streak-math-abz 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.

  3. Did it already run?

    If streak-math-abz 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.

  4. How O3 protects you

    O3 blocks streak-math-abz 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.

Frequently asked questions

No. streak-math-abz on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
