The Complete Guide to Hunting Cobalt Strike – Part 1: Detecting in Open Directories

This report details an investigation that used AttackCapture™ to discover and map thousands of Cobalt Strike deployments exposed in open web directories; it analyzes sample payloads (shortcut lures, PowerShell encoded loaders, in-memory shellcode), links infrastructure via certificate and fingerprint pivots, provides a list of confirmed IOCs, maps observed behaviors to MITRE ATT&CK, and offers concrete mitigation guidance such as blocking certificates, hardening directory listings, and detecting encoded PowerShell and memory injection patterns.
