MAL-2026-4264 Malicious code in dds-js-idl (npm)

On npm install, postinstall.js runs whoami via execSync and collects os.hostname(), os.platform(), cwd, and CI/GitHub env vars, then exfiltrates them over HTTPS GET to lg5ys3jebfzwk366pilidbmah1nsbszh.oastify.com/nasa/dds-js-canary/ and additionally performs a DNS lookup of ${whoami}.lg5ys3jebfzwk366pilidbmah1nsbszh.oastify.com as a DNS-channel fallback that defeats egress HTTPS filtering. The package self-describes as a Security research canary — NASA VDP, but it fires on every install without consent and leaks installer identity and repository/CI context to a third-party Interactsh (oastify.com) collector controlled by the canary operator. Regardless of stated research intent, the structural behavior is install-time host fingerprinting and out-of-band exfiltration.

The OpenSSF Package Analysis project identified 'dds-js-idl' @ 1.0.0 (npm) as malicious.
