DeLorme’s inReach service was hacked this week, but company officials said no financial information of customers was exposed.

The Yarmouth company detected the hack and shut down the service within 24 hours, said spokeswoman Kim Stiver.

InReach is a global satellite communications device designed for use in remote areas. It allows users to send and receive text messages, inform friends and family members of their locations, and contact rescue services with location information if needed.

The company said the hackers may have obtained inReach customers’ names, mailing addresses, email addresses, telephone numbers and, in some cases, dates of birth and information for emergency contacts. No other information, including financial information, was exposed, the company said, and the hack affected only inReach communicator accounts that were opened in the period from July 30, 2014, to March 5.

DeLorme said it doesn’t collect customers’ Social Security numbers.

Messages sent to and from inReach customers were not compromised, Stiver said.

Stiver said the FBI was contacted because DeLorme has government contracts, and the bureau is investigating the hack. She said the company doesn’t know whether investigators have determined where the hack originated.
