Notice regarding the use of the WeChat mobile app


Dear Users,

on 30th November 2023 a notice was issued from the National Cyber and Information Security Agency (NÚKIB) regarding the use of the WeChat mobile app and its Chinese version of Tencent’s Wixin.

From a cybersecurity point of view, WeChat, like TikTok, collects excessive amounts of user data to help attackers target an attack on a user or blackmail them.

Protect your privacy and our University from a cyber attack.

In particular, the app collects information from your mobile phones

Based on the Warning issued, we take precautions:

If you have a WeChat application on a business device (mobile phone, laptop, tablet) or on a private device that you are connecting to our network (laptop with VPN, etc.), you need to uninstall the WeChat application from these devices and do not use its web version.

More information directly on the NÚKIB website

Thank you for your cooperation,

Cyber Security Manager of Charles University
