Malicious code in hardhat-ftp (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

--- _-= Per source details.

After string-array decoding the loader resolves to execSync and spawn sinks, and the package declares axios as a dependency, giving the import-time payload both outbound HTTP and local command-execution primitives with the concrete command targets concealed behind the obfuscation. The surrounding package is a cover: it is published under the name hardhat-ftp with a vulnerability-management description, but the README headers, badges, and ecosystem links are lifted from pinojs/pino, and the files under lib/ (proto.js, levels.js, transport.js, multistream.js) mirror the pino source tree. The name/README/code mismatch, the scale of the obfuscation, and the presence of exec+HTTP primitives inside the auto-loaded module match the masquerade-dropper pattern: installing or requiring this package triggers execution of concealed attacker-controlled code on the installer's host.
