‘Malicious’ threat targets Pulaski Electric System in ‘cyber attack,’ interrupting customer services
Pulaski Electric System reports that the attack is disrupting bill payments and other services.
NASHVILLE, Tenn. (WSMV) - Weeks of interruptions to Pulaski Electric System (PES) services for customers have been caused by a cyber attack, the utility provider revealed this week.
“PES has learned that it was the victim of a cybersecurity attack by a malicious threat actor,” a statement from the provider said in part.
Despite the interruptions, PES said as of Monday that “remediation efforts have found no sensitive customer information has been impacted.”
The company first noticed “suspicious activity on its network” on December 4, leading personnel to disconnect “all of its systems and machines” in order to be cautious. Next, leaders began working with IT teams and a “specialized cybersecurity team and various third party vendors” to bring the system back online.
During those efforts, the Pulaski organization discovered the attack and notified the U.S. Cybersecurity and Infrastructure Security Agency (CISA).
Customers have reported seeing interruptions with bill payments and other online systems this month, and PES confirmed that the breach and subsequent response are causing interruptions with bill payment, new customer installation and broadband troubleshooting.
“We are aware that some customers were unable to make bill payments on Friday, December 5, and Monday through Wednesday, December 8–10,” a Facebook post from PES said. “As a result, any scheduled service disconnections have been postponed and will resume on Wednesday, December 17.”

The utility provider said it will be in touch with customers as the investigation continues and will notify them if they discover any personal information was accessed by the hackers.
“Should PES determine that any of our customers’ sensitive personal information has been impacted by this event, PES will send written notices to all impacted persons in accordance with applicable data privacy laws,” the statement said.
