At least four U.S. pipeline companies have seen their electronic systems for communicating with customers shut down over the last few days, with three confirming it resulted from a cyberattack.
On Tuesday, Oneok Inc., which operates natural gas pipelines in the Permian Basin in Texas and the Rocky Mountains region, said it disabled its system as a precaution after determining that a third-party provider was the “target of an apparent cyberattack."
A day earlier, Energy Transfer Partners LP, Boardwalk Pipeline Partners LP, and Chesapeake Utilities Corp.’s Eastern Shore Natural Gas reported communications breakdowns, with Eastern Shore saying its outage occurred on March 29. The Department of Homeland Security, which said Monday it was gathering information about the attacks, had no immediate comment Tuesday.
“We do not believe any customer data was compromised,” said the Latitude Technologies unit of Energy Services Group, which Energy Transfer and Eastern Shore both identified as their third-party provider. “We are investigating the re-establishment of this data,” Latitude said in a message to customers.
