Chinese netizens recently reported that police have begun checking people’s smartphones with a special mobile device at subway stations and on the streets of Beijing and Shanghai.
Checkpoints
A Beijing netizen sent a video to the Chinese-language Epoch Times on June 17, which showed that Beijing police have set up a temporary checkpoint at the Dongzhimen Subway Station to check travelers’ smartphones.“The police is checking everything on the phone,” the person shooting the video can be heard saying.
Several netizens from Shanghai and Beijing told NTD that the police mainly check whether there are photos or videos about recent Hong Kong protests against a controversial extradition bill, a topic banned in mainland China. The police also look for whether people have installed virtual private network (VPN) and other apps that can allow users to bypass the Chinese firewall and access foreign websites that are banned inside China.
On June 21, the Beijing police department published a statement on its official Weibo account, denying netizens’ complaints that officers were accessing people’s smartphones.
Surveillance Tool
The statement also explained what the device does: “Police can use this ‘smartphone’ [mobile police terminal] to accomplish all types of police work. This device is the perfect embodiment of advanced police technology as well as applying big data.”“Mobile police terminal” devices have proliferated in certain years. Many software developers tout their success at scoring government clients.
For foreigners, their profiles and passport numbers can be accessed after police take a photo or a finger scan with the device. The police can also input more information about the foreigner’s behavior into the database.
Surveillance App
Since 2016, netizens have complained that after police checked their phones, a MFsocket app mysteriously appears on their phones. They are unable to uninstall it.Alderson found out: “[MFsocket] is asking a lot of dangerous permissions: - Read your call log, your contacts, your SMS, your calendar, your SD card - Disable the lock screen - Access your location - install a new app without your consent.”
“Moreover, we can see that the activity doesn’t have the category launcher which means that this app doesn’t have an icon,” Alderson wrote.
He concluded that the app was a surveillance tool.
