The Administrative Office of Pennsylvania Courts website was hit by a cyberattack over the weekend, taking public systems offline, but not compromising any data, officials said.

The federal government’s lead cybersecurity agency, the U.S. Department of Homeland Security and the FBI were investigating the attack, Chief Justice Debra Todd said in a statement.

She called it a “denial of service” cyberattack, using the federal government’s description for when attackers “flood the targeted host or network with traffic until the target cannot respond or simply crashes, preventing access for legitimate users.”

Courts and court services remained open Monday, including in McKean County. President Judge John Pavlock said, “No court proceedings or actions have been postponed locally. The only impact is the ability to immediately obtain and enter data.”

At the Bradford office of District Judge Rich Luther, the systems were up and running on the court’s side, despite the public side being down.

“We’re still open with business as usual,” office manager Kathy Webster told The Era.

According to the AOPC, as of early afternoon, the systems that were still down included PACFile, the Pennsylvania Appellate Court electronic filing system used by attorneys and pro se litigants to electronically file documents with appellate courts or common pleas courts; Guardianship Tracking System for reports on incapacitated persons, while filing offices remain open to accept reports; web dockets for the public to view; and online payment systems.

Other systems were reported to be slower than usual, but still operational.

Bradford City Police Chief Mike Ward said there were some issues, “But it has been accessible for us. So very little impact.”

Foster Township was having issues with things running slowly, but were still operational, Lt. Mike Thomas confirmed.

Bradford Township Police Chief Robb Shipman said things were working normally there.
