streak-math-metricsnpm
Advisory published Updated
streak-math-metrics is a confirmed malicious npm package (MAL-2026-12000) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in streak-math-metrics (npm)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for streak-math-metrics (version 1.0.0).
If you installed it — respond
streak-math-metrics 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.
Did it already run?
If streak-math-metrics 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.

Detect & block this
O3 blocks streak-math-metrics-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
