Online posts of purportedly secret documents relating to the F-35, F-15, and some advanced weapons systems appear to be genuine, according to a Chinese intelligence expert.
The South China Morning Post, an independent newspaper in Hong Kong, said the expert, a man named Tang, an executive of Beijing-based antivirus and security company Rising Information Technology, reviewed some of the documents posted on the encrypted forum Telegram by Ivan Ivanof, who claims to be a Russian military pilot.
