Open Source Intelligence Gathering Against OT Infrastructure
HYPOTHESIS
If CyberAv3ngers used OSINT (vendor documentation, ICS-CERT advisories, CISA alerts, vendor bulletins) to profile targeted water utility control systems, publicly available information about the utilities' PLC models, firmware versions, and network topology will correlate with the specific exploitation techniques used — indicating prior intelligence gathering rather than opportunistic targeting.
DATA SOURCES
CISA ICS-CERT advisories (cross-reference with target inventory)Public procurement documents and RFPs for OT systemsBrowser history and search logs from engineering workstationsICS threat intelligence feeds (Dragos, Claroty, Waterfall)
Priority: LOW
NOTES
This is primarily an attribution and targeting-analysis hunt rather than a technical detection. More useful for understanding actor capability and target selection logic than for real-time detection. Useful for threat modeling: if your OT systems are mentioned in public CVE/advisory documentation with specific firmware versions, they are likely in CyberAv3ngers target lists.
