title: Axios NPM Compromise Malicious C2 Domain DNS Query id: 73e5d24f-493f-4092-bd2f-c72cabda40ee status: experimental 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. references: - https://www.stepsecurity.io/blog/axios-compromised-on-npm-malicious-versions-drop-remote-access-trojan - https://www.derp.ca/research/axios-npm-supply-chain-rat/ - https://www.trendmicro.com/zh_hk/research/26/c/axios-npm-package-compromised.html - https://www.elastic.co/security-labs/axios-supply-chain-compromise-detections - https://www.virustotal.com/gui/file/e10b1fa84f1d6481625f741b69892780140d4e0e7769e7491e5f4d894c2e0e09 - https://www.huntress.com/blog/supply-chain-compromise-axios-npm-package author: Swachchhanda Shrawan Poudel (Nextron Systems) date: 2026-04-01 tags: - attack.command-and-control - attack.t1071.001 - attack.t1568 - detection.emerging-threats logsource: category: dns detection: selection: query: - 'sfrclak.com' - 'calltan.com' - 'callnrwise.com' condition: selection falsepositives: - Unlikely level: high
