Chinese Authorities Are Using a New Tool To Hack Seized Phones and Extract Data

An anonymous reader quotes a report from TechCrunch: Security researchers say Chinese authorities are using a new type of malware to extract data from seized phones, allowing them to obtain text messages -- including from chat apps such as Signal -- images, location histories, audio recordings, contacts, and more. In a report shared exclusively with TechCrunch, mobile cybersecurity company Lookout detailed the hacking tool called Massistant, which the company said was developed by Chinese tech giant Xiamen Meiya Pico.

Massistant, according to Lookout, is Android software used for the forensic extraction of data from mobile phones, meaning the authorities using it need to have physical access to those devices. While Lookout doesn't know for sure which Chinese police agencies are using the tool, its use is assumed widespread, which means Chinese residents, as well as travelers to China, should be aware of the tool's existence and the risks it poses.

The good news... is that Massistant leaves evidence of its compromise on the seized device, meaning users can potentially identify and delete the malware, either because the hacking tool appears as an app, or can be found and deleted using more sophisticated tools such as the Android Debug Bridge, a command line tool that lets a user connect to a device through their computer. The bad news is that at the time of installing Massistant, the damage is done, and authorities already have the person's data. 'It's a big concern. I think anybody who's traveling in the region needs to be aware that the device that they bring into the country could very well be confiscated and anything that's on it could be collected,' said Kristina Balaam, a researcher at Lookout who analyzed the malware. 'I think it's something everybody should be aware of if they're traveling in the region.'
