Which versions of streak-math-abz are malicious?

The following npm versions of streak-math-abz are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate streak-math-abz if I installed it?

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.

I already installed streak-math-abz — how do I know if it already compromised me?

If streak-math-abz was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is streak-math-abz part of a known attack campaign?

Yes — streak-math-abz is associated with the IN-MAL-2026-011334 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find streak-math-abz across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for streak-math-abz (version 1.0.0).

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.
