@nstrlabs/utils@99.0.1

Malicious code in @nstrlabs/utils (npm)

T1195.002 · Compromise Software Supply Chain

Analysis

@nstrlabs/utils@99.0.1 is a 642-byte dependency-confusion stub (scoped name, version 99) whose preinstall exfiltrates hostname, username, cwd and path via a DNS tunnel to oast[.]live and an HTTP POST to 172[.]201[.]213[.]59:9090. The unverifiable 'security research' description (no repo URL or program reference) masks a host-metadata stealer.
