LetMeSpy Reports Massive Data Theft in Recent Attack by Hackers

A popular Android phone tracking app, LetMeSpy in a statement disclosed a data breach incident that allowed an unauthorized third-party to steal sensitive information of thousands of users.

The security breach occurred in late June 2023, when an unknown hacker compromised the spyware’s network system and exfiltrated email addresses, phone numbers, call logs, messages, and location information of its website users.

On discovering the incident, the company immediately informed the concerned law enforcement and Polish data protection authority, UODO. As a containment measure, LetMeSpy has suspended all account-related activities (website and app). The threat actor as well as their motive behind the attack remains unknown.

LetMeSpy, a phone monitoring app, also known as stalkerware or spouseware was marketed as a parental or employee control tool (2013). Built by a Polish developer, Rafal Lidwin, the app comes with a monthly subscription, $6 for Standard and $12 for Pro. It allows its subscribers to track others by installing the app on their phone. The app provides real-time tracking by stealthily uploading the target’s location, messages, and call logs to its remote servers. This data can be accessed by its customers on LetMeSpy’s website.

In January 2023, the data on LetMeSpy’s website revealed that its app had been used to track 236,322 phones worldwide. It had collected more than 63.5 million text messages, 39.7 million call logs, and 43.2 million locations.

The data breach was first reported by a Polish security research blog Niebezpiecznik. In addition to analyzing the stolen data that included information on thousands of users, the researchers also reached out to LetMeSpy for confirmation, but the response came from the hackers instead. They claimed to have taken over the spymaker’s domain and reportedly deleted the databases stored on the server.

Moreover, TechCrunch’s analysis of the leaked information revealed that the stolen user records date back to 2013, when LetMeSpy was first launched. It also contained information on nearly 13,000 compromised devices and 13,400 locations of thousands of victims. The location points revealed that the majority of victims were from the US, India, and Western Africa.
