Garmin is reportedly being asked to pay a $10 million ransom to free its systems from a cyberattack that has taken down many of its services for two days.

The navigation company was hit by a ransomware attack on Thursday, leaving customers unable to log fitness sessions in Garmin apps and pilots unable to download flight plans for aircraft navigation systems, among other problems. The company’s communication systems have also been taken offline, leaving it unable to respond to disgruntled customers.
