The GPS device maker Garmin has acknowledged being hit by a cyber attack last week that encrypted some of its systems, knocking its fitness tracking and pilot navigation services offline.
It said systems would be fully restored in the next few days.
In a statement, the company did not specify that it was the target of a ransomware attack, in which hackers infiltrate a company's network and use encryption to scramble data until payment is received.
But a person familiar with the incident response told the Associated Press the attackers had turned over decryption keys that would allow Garmin to unlock the data scrambled in the attack.
The attack crippled company services including Garmin Connect, which is popular with runners and cyclists for tracking workouts, and the FlyGarmin navigation service for pilots.
Garmin said on Monday that, in addition to GPS-based services, customer support and company communications were also interrupted by the July 23 attack.
