7 analysed samples communicate with this URL, including Fileinfector.

How was doh.cq0.co checked?

A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the fast tier allows, a headless browser rendered the page and recorded every request. Egress is SSRF-locked. Signatures that matched only page text are weighted far below one that matched a served file, because a page documenting malware matches the same rules.
