U.S. Pipeline Hack Attack: Global Cybersecurity Matters

Last Friday, a hacker group called DarkSide deployed a ransomware attack on a pipeline system that carries nearly half of the U.S. east coast's fuel supply.

Colonial Pipeline restarted operations on Wednesday evening as panic-induced gas shortages swept across the East Coast and Gulf coast states. The White House said it's closely watching supply shortages. How did the pipeline attack unfold? What does it say about national security cyber-vulnerabilities for all countries?
