MAL-2026-17922 Malicious code in @pkgship/frpc-linux-arm64 (npm)

Package @pkgship/frpc-linux-arm64 is a platform-specific distribution (linux-arm64) consistent with the common pattern of shipping a prebuilt native binary (frpc, a well-known reverse-proxy client) for a parent package to select via optionalDependencies at install time. No lifecycle scripts, remote fetch-and-execute, credential access, environment scraping, or network callbacks were observed in the two files scanned. The package's only install-time effect is placing a prebuilt binary on disk; it is not auto-executed by npm install.

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.
