In late April 2021, Colonial Pipeline experienced a significant ransomware attack by the DarkSide gang, leading to the shutdown of critical infrastructure. This caused widespread gasoline shortages across the East Coast of the United States, resulting in panic and unsafe hoarding behaviors among consumers. The attack targeted the firm's billing system and internal business network. To mitigate further disruption, Colonial Pipeline conceded to the demands and paid $4.4 million in bitcoin. This incident highlighted vulnerabilities in critical infrastructure's cybersecurity measures and emphasized the need for stronger protections to prevent such attacks.
