This rule performs a sweep across device file and network events for indicators of compromise (IOCs) associated with the UAT-11587/Antino campaign. It detects malicious file hashes, specific C2 domain connections, and known lure URLs (HTA/WSF) identified by Cisco Talos.
Detects inbound phishing emails containing brand mentions for Signal, WhatsApp, or Telegram alongside lure phrases related to verification, 2FA, or device linking. The rule specifically filters for emails containing URLs while excluding messages originating from official domains associated with these services.

This rule detects an exploitation attempt targeting a memory overflow vulnerability in Citrix NetScaler Gateway, specifically identifying oversized DTLS handshake length fields in UDP traffic. The rule triggers when a DTLS packet exceeds the specified size threshold, which is indicative of a buffer overflow attack intended to cause a service crash (Denial of Service).
