The National Bureau of Cyber and Information Security (NÚKIB) has issued a warning against installing and using the Chinese TikTok application on devices with access to systems belonging to critical information infrastructure and other important information systems.

The authority said today that the application poses a security threat. The office and the general public are advised to consider the use of the application and what people share through it.

US lawmakers have introduced a bill to ban the app, which US government workers are already prohibited from installing on their devices. The Czech government, while part of the EU, has not introduced a ban so far.

In a report published last year, the Czech national intelligence agency BIS singled China out as a major threat targeting Czech cyberspace.

“Chinese technologies penetrating important networks of state infrastructures… can be evaluated as a major security threat,” it said.
