• •Chinese authorities are using Massistant, a new forensic data extraction malware, to obtain data from seized phones.
• •Massistant, developed by Xiamen Meiya Pico, can extract text messages, images, location histories, and more.
• •The malware must be installed on an unlocked device and is used in conjunction with a hardware tower.
• •Massistant leaves evidence of its compromise, but the damage is done once installed, as authorities already have access to the user's data.

Security researchers have discovered a new malware called Massistant, developed by Chinese tech giant Xiamen Meiya Pico, used by Chinese authorities to extract data from seized phones. The malware allows access to text messages, images, location history, and more, requiring physical access to the devices. Massistant is part of a broader ecosystem of surveillance technology in China, and while it leaves traces, the damage is done once installed. Travelers to China are particularly at risk, as devices can be confiscated and data accessed without warrants.
