135: The D.R. Incident

Detection Challenges

Omar Avilez recounts the detection challenges faced during a major cybersecurity incident in the Dominican Republic. The attackers attempted to disrupt critical infrastructure but lacked the skillset to control operational technology systems, which prevented significant damage 1. Jack Rhysider reflects on the vulnerability of digital systems, sharing a recurring dream that symbolizes the feeling of helplessness in the face of relentless cyber threats 2.

I keep going into room after room, shutting doors, locking it, but it just keeps getting in. I usually wake up around here heart racing. I'm in a panic. And what I often feel after this dream is helplessness. Complete vulnerability.
