According to a sample of user data L&M shared with Motherboard, the hacker has scraped a treasure trove of information from ProTrack and iTrack customers, including: name and model of the GPS tracking devices they use, the devices' unique ID numbers (technically known as an IMEI number); usernames, real names, phone numbers, email addresses, and physical addresses. (According to L&M, he was not able to get all of this information for all users; for some users he was only able to get some of the above information.)
