WASHINGTON/SAN FRANCISCO—The ransomware gang accused of crippling the leading U.S. fuel pipeline operator said on Monday that it never meant to create havoc, an unusual statement that experts saw as a sign the cybercriminals’ scheme had gone awry.
The FBI accused the group that calls itself DarkSide of a digital extortion attempt that prompted Colonial Pipeline to shut down its network, potentially causing extraordinary disruption as gasoline deliveries dry up.
