NeedyMantis C2 TLS SNI to corp.tripswithengine.com
Detects egress to the NeedyMantis C2 domain corp.tripswithengine[.]com across three vantage points: TLS SNI (port 443), DNS resolution, and HTTP Host header. Each content match is anchored to the start of its buffer ('startswith') so a different domain that merely contains 'corp.tripswithengine.com' as a suffix of a longer label (e.g. 'notcorp.tripswithengine.com') cannot match — only this exact domain or a genuine subdomain of it triggers.
