Port of Seattle investigating ‘unauthorized activity’ that led to cyberattack; no timeline for outage fix

The Port of Seattle continues to deal with an ongoing cyberattack that began Saturday and was still affecting various operations through Sunday, including at Seattle-Tacoma International Airport.

The Port detected “unauthorized activity” on its systems Saturday morning in what it believes was a cyberattack, said Lance Lyttle, managing director of aviation for Sea-Tac Airport.

“We can’t yet say when this will be resolved,” Lyttle said at a media press conference Sunday.
