The cyber attack on the Mat-Su Borough is expected to cost more than a half-million dollars.

IT Director Eric Wyatt gave assembly members at update at their meeting Monday night, a week after a computer virus shut down the borough’s network.

Wyatt described the attack as a multi-pronged approached—including Trojan Horse and Ransomware—that was “the worst of its kind in the nation.”

Staff have spent the past two weeks wiping the borough’s 500 computers and are now installing new hardware and software systems.

In his report, Wyatt said attacks of this nature can cost agencies up to $1 million. Wyatt says the borough is looking at about a half-million dollar cost right now-- but that could increase if they find additional problems.

Mat-Su Borough Manager John Moosey said the borough had declared the attack an emergency so it could be eligible for funding through FEMA, the Federal Emergency Management Agency. He said the borough also has insurance that could cover part of the costs.

“We’re hopeful we’re not going to have to bear this expense alone,” Wyatt said.

Wyatt said the FBI is analyzing evidence from the attack to see if it can trace where the virus came from.

He said many of the phone systems have been restored and expects the most of the borough’s computer network to be back online in the next three weeks.

“We are taking what we learned from our particular experience and we’re giving that to other people to help them to know what to look for and how to guard their systems against this type of attack,” Wyatt said.
