The Coast Guard and FBI are investigating after two oil tankers bound for the U.S. were hit with suspected cyberattacks last month, prompting American authorities to launch investigations into both incidents, sources told ABC News. On Aug. 21, one of the tankers, described as a “foreign-flagged commercial vessel” was boarded by a “highly specialized team” of U.S. Coast Guard law enforcement officers, cyber protection members and an FBI cyber team in the Gulf of Mexico, according to a joint statement from both agencies. “The measures were designed to ensure integrity of the vessel’s operational and information technology systems following indications that the vessel’s network were compromised by foreign cyber actors,” the statement said.
