The public websites of more than half of 1,550 utilities in the U.S. and other countries assessed by security ratings firm Bitsight, use outdated software, according to a June report. This gives attackers an opening to companies’ systems, the report said.
Utilities are also wary about cyber threats targeting their supply chains. Many companies that do business with power suppliers have weaker cybersecurity safeguards than the utilities do, said Jake Olcott, Bitsight’s vice president for communications and government affairs.
