A group of hackers says they have obtained internal files from three Chinese social media monitoring companies. After leaking some of the documents, the group was banned by Twitter under its hacked files policy, however, Motherboard has been unable to confirm the authenticity of the documents.

The group goes by the name CCP Unmasked, in reference to the Chinese Communist Party ruling the country. The group reached out to journalists on Thursday, pitching "a large dump of files" that they said exposes social media monitoring and disinformation campaigns conducted by three private companies at the behest of the Chinese government. They claim to have stolen internal documents from Knowlesys, a company based in Hong Kong and GuangDong, Yunrun Big Data Service, a company based in Guangzhou, and OneSight, based in Beijing.
