MAL-2026-13915

Summary: Malicious code in kit-map-vim (npm)

Details: Source: amazon-inspector (03873a12af48745e3fd5173ce736267aebd3290be427275073562b8e1ada61fc) On import of kit-map-vim, dist/index.mjs unconditionally spawns dist/internal/calc-math.dat as a detached child process after a SHA-256 self-check. The.dat file is a Linux x86_64 ELF RedShell remote-access implant disguised as a 'native math accelerator'. The implant beacons to hardcoded C2 host 217.60.77.63 over plain HTTP and exposes command handlers that download and execute additional ELF binaries and shellcode from http://217.60.77.63/Others/* and /SC/* endpoints, including in-memory execution via memfd_create/fexecve to avoid touching disk. It installs a masquerading systemd user unit 'svc-update.service' (Description=System Update Service, Restart=always) for persistence, provides SOCKS5 proxy and TCP port-forwarding, and offers built-in commands to enumerate users/env/processes/network configuration, harvest SSH keys and credentials from ~/.ssh and credential stores, and stream arbitrary filesystem paths to the operator via a chunked 'POST /api/extract-receive' handler labeled with a 'Loot_*' destination. The package's stated day-math purpose has no need for a native binary; the ELF's exposed command set (RedShell) is unrelated to any math functionality.

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.
