What this malware does

[email protected] presents itself as a calendar/streak math helper but its main entry runs a top-level IIFE that copies a bundled binary (dist/cache.bin) to /tmp/sm-data/w.bin and spawns it via child_process.spawn whenever the module is imported. The dropped file is a Linux x86_64 ELF remote-access implant with a hardcoded C2 at 217.60.77.63, exposing a command menu (/redshell, /persist, /socks, /portfwd, /spawn, /ssh_keys, /creds, /dbfind, /dataextract, /download) that provides interactive shell, SOCKS5 proxy, TCP port-forwarding, memfd download-and-execute of additional ELFs/shellcode, and systemd user-service persistence written as svc-update.service. The implant enumerates and exfiltrates SSH keys, credentials, and arbitrary filesystem paths, uploading via chunked HTTP POST /api/extract-receive to the C2 and via litterbox.catbox.moe. The loader uses deliberately generic identifiers (sm-data, w.bin, cache.bin) and an 'INTERNAL DATA SYNC' comment to disguise the dropper, and swallows errors to run silently.

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-metricsaz (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-metricsaz across your stack and pipelines.

  2. If you installed it — respond

    streak-metricsaz 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-metricsaz 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-metricsaz 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
