Preventing Initial Access in Industrial Environments

Dragos provides a high-level analysis of how its tracked activity groups gain initial access to industrial/ICS environments, emphasizing that attackers more commonly enter corporate/IT networks as precursors to pivoting into OT. The report highlights the top MITRE ATT&CK for ICS initial access techniques (spearphishing attachments, supply chain compromise, exploitation of remote services/public-facing applications, and drive-by compromise), discusses why defenders should prioritize TTPs over ephemeral IOCs, and points readers to a full whitepaper and Dragos WorldView for detailed technical and defensive guidance.
