German spy agency warns of Chinese LinkedIn espionage

China is using fake LinkedIn profiles to gather information on German officials and politicians, the German intelligence agency (BfV) has said.

The agency alleges that Chinese intelligence used the networking site to target at least 10,000 Germans, possibly to recruit them as informants.

It released a number of fake profiles allegedly used for this purpose.

BfV head Hans-Georg Maassen said the accounts show China's efforts to subvert top-level German politics.

"This is a broad-based attempt to infiltrate in particular parliaments, ministries and government agencies," he said.

China has denied similar allegations of cyber espionage in the past and has not yet responded to the German allegation.

The BfV published eight of what they say are the most active profiles used to contact German LinkedIn users. They are designed to look enticing to other users, and promote young Chinese professionals -who do not exist.

Some of the accounts include "Allen Liu", said to be a human resources manager at an economic consultancy, and "Lily Wu", who reportedly works at a think tank in eastern China.

The BfV says both accounts are fake.

The agency is increasingly worried that Chinese intelligence is using the method to recruit high-ranking politicians as informants.

They asked users who believed they had been targeted by suspect accounts to contact them.

Last year, the BfV said they had detected "increasingly aggressive cyber-espionage" including "intensifying" attempts to influence September's parliamentary elections.

They said the hacker group known as "Fancy Bear" or APT28 was especially active - and it is believed to be controlled by the Russian state.
