## What is MAL-2026-12000?

MAL-2026-12000 is a malicious package in streak-math-metrics, published on 5 Aug 2026. 

### Official description

The package's module entry dist/index.mjs runs a top-level IIFE on import that chmods dist/math-calc.bin to 0755 and spawns it detached. dist/math-calc.bin is a Linux x86_64 ELF linked against libssl/libcrypto implementing a RedShell-style remote-access agent: /bin/sh-backed command execution, HTTP downloaders that fetch payloads from 217.60.77.63 under /Others/ and /SC/ paths and execute them from /tmp or via memfd_create, a SOCKS5 proxy, TCP port forwarders, credential/SSH-key/database collectors, and a persistence installer that drops a systemd user unit at ~/.config/systemd/user/svc-update.service (masquerading as 'System Update Service') with Restart=always. A sha256 'integrity check' is present in the JS wrapper but its mismatch branch only logs and still proceeds, and the wrapper's comments and log strings ('Native accelerator loaded and verified.', 'Performance mode enabled.') present the implant as a native math accelerator despite the package having no plausible need for a native binary. Any consumer that imports the package hands a remote operator interactive shell, file/credential exfiltration, arbitrary payload execution, and persistence on the installer host.

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.

## What should I do about MAL-2026-12000?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
