Security firm Mandiant has come out with quite the startling report titled "APT1: Exposing One of China's Cyber Espionage Units", which has tracked the alleged military-backed Chinese hacking group dubbed as Advanced Persistent Threat 1 all the way back to 2006.
Mandiant have written "Our analysis has led us to conclude that APT1 is likely government-sponsored and one of the most persistent of China's cyber threat actors." The group is also believed to be the 2nd Bureau of the People's Liberation Army (PLA) General Staff Department's (GSD) 3rd Department, otherwise known as Unit 61398.
The New York Times have written about it, where they worked off an advance copy of the report, which led them to buildings in Shanghai which they believe is where the unit is based. The Times then encountered persistent attacks from Chinese hackers last year, where they worked with Mandiant to monitor and block the intrusions into their network.
Chinese officials have of course dismissed the claims of state-sponsored hacking as "groundless", but we've seen media organizations such as Bloomberg and The Wall Street Journal, as well as many other companies stepping forward claiming that they have found themselves under similar attack.
