[Hackers demand $6 million in bitcoin ransom from Seattle airport operator to retrieve stolen files] On September 19, an official at Seattle-Tacoma International Airport said on Wednesday that hackers demanded $6 million worth of bitcoin from the airport operator in exchange for files stolen in a cyberattack last month, which were posted on the dark web this week. The official said the Port of Seattle, which owns and operates the airport, has decided not to pay. Lance Lyttle, the airport's aviation director, said the airport had previously linked the attack to a ransomware gang called Rhysida, and now the FBI is conducting a criminal investigation. "On Monday, the hacker posted a copy of eight files stolen from the Port system on the dark web and sought 100 bitcoins to buy the data." Lyttle told a U.S. Senate committee that the airport appeared to have blocked the attack, but the hacker was able to encrypt some data.
