The ransomware attack on US energy firm Colonial Pipeline last week caused significant disruptions to fuel delivery on the East Coast, as the firm suspended most of its operations in a bid to stem the spread of malware. With Colonial pipeline transporting nearly half of US East Coast's fuel supply, this incident highlights the growing threat that cyber attacks pose to critical infrastructure. Our latest analysis examines how this activity compares with the perpetrators' (the DarkSide operators) previous activity and what Colonial Pipeline and Washington's response towards this incident could mean for America's energy security.

This analysis was made prior to the 12 May announcement that Colonial Pipeline was restarting some of its services. Nevertheless, the analysis in the podcast will still remain relevant until the pipeline is fully functional later this week.
