Axios NPM Compromise Malicious C2 Domain DNS Query

Description

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 (plain-crypto-js@4.2.1) 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.
