What’s past is prologue – A new world of critical infrastructure security
Summary: Cisco Talos recounts that in May 2021 DarkSide ransomware hit Colonial Pipeline, which carries 45 percent of East Coast petroleum delivery, forcing a pipeline shutdown and a weeklong fuel supply delay; on May 13, 71 percent of North Carolina gas stations reported being out of fuel. The article ties this to earlier incidents - a 2018 malware event at Energy Services Group and a 2019 Ryuk ransomware outbreak at a natural gas compression facility that caused a 30-hour OT outage - and notes the Biden administration's May 12 Executive Order and May 27 DHS/TSA pipeline cybersecurity requirements followed.
What you should know: A ransomware attack on IT systems, not control systems, was enough to halt 45 percent of East Coast petroleum delivery and empty 71 percent of North Carolina's gas stations - and the article notes multiple agencies, including DHS, CISA, TSA and DOE, are now issuing overlapping pipeline rules that operators must reconcile.
