But it wasn't until this month's ransomware attack against Colonial Pipeline Co. that the real-world impact became tangible. The cyberattack by the DarkSide ransomware gang forced the Georgia-based company to shut down its entire 5,500-mile pipeline system, which supplies nearly half the fuel used along the U.S. East Coast. The hack exposed vulnerabilities in U.S. defenses and has already been dubbed a wake-up call for the Biden administration.
