The package's main entry dist/index.mjs runs a top-level IIFE that chmod +x's a bundled ELF at dist/math-calc.bin and spawns it detached with piped stdio on any import/require. A hardcoded sha256 comparison is decorative — both branches proceed to spawn the binary. The ELF is a remote-access implant that beacons to 217.60.77.63: it downloads additional ELFs and shellcode from http://217.60.77.63/Others/<file> and /SC/<file> and executes them via mktemp+chmod+x or memfdcreate, dispatches arbitrary shell commands via /bin/sh and /bin/bash, harvests SSH private keys, stored credentials, and database configs via /sshkeys, /creds, /dbfind commands, and streams collected data chunked over POST /api/extract-receive to the C2 with additional exfiltration to litterbox.catbox.moe. A /persist command writes ~/.config/systemd/user/svc-update.service (labeled 'System Update Service') pointing at /proc/self/exe with Restart=always and enables it via systemctl --user for reboot persistence. The 'math accelerator' framing in the package description does not disclose the bundled ELF or its execution on import.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
