Detects DNS queries for the malicious C2 domain associated with the plain-crypto-js/Axios npm package supply chain compromise.
On March 30, 2026, malicious versions (1.14.1, 0.30.4) were published to npm, injecting a dependency ([email protected]) that executed a postinstall script as a cross-platform RAT dropper.
This detection detects endpoints attempting to resolve the attacker's C2 domain (sfrclak.com) used for command and control communication.
