Energy Secretary Jennifer Granholm on Sunday called for more public-private cooperation on cyber defenses and said U.S. adversaries already are capable of using cyber intrusions to shut down the U.S. power grid.
“I think that there are very malign actors who are trying,” she said. She added: “Even as we speak, there are thousands of attacks on all aspects of the energy sector and the private sector generally.”
Granholm noted, without mentioning the company by name, that Colonial Pipeline Co. was hit in May with a crippling cyberattack by a ransomware group. Colonial temporarily shut down its gasoline distribution networks in the South before paying $4.4 million to the hackers. She urged energy companies to resist paying ransom.
“The bottom line is, people, whether you’re private sector, public sector, whatever, you shouldn’t be paying ransomware attacks, because it only encourages the bad guys,” she said.
Granholm even spoke in favor of having a law that would ban paying such ransom, though she said, “I don’t know whether Congress or the president is at that point.” Asked whether American adversaries have the capability now of shutting down the U.S. power grid, she said: “Yes, they do.”
