Russia's GRU spy agency has suffered a new humiliation after a list of over 300 names of suspected agents was discovered online.

Following this week's disclosure by Dutch and British authorities of the identities of four Russian GRU operators conspiring to hack the headquarters of the world's chemical weapons testing authority, further database research has revealed 305 other individuals thought to be working for the Russian intelligence agency.

In a co-ordinated response, the Dutch Military Intelligence and Security Service (MIVD) and Britain’s Ministry of Justice named the four men as Aleksei Morenets, Evgenii Serebriakov, Oleg Sotnikov and Aleksey Minin.

All were said to be part of Unit 26165, also known as “GRU 85 Main Special Service Centre”.

Although thought to be alias names, like the perpetrators of the Salisbury nerve-agent attack, analysis by the civilian open-source intelligence group Bellingcat of data from different databases between 2002 and 2014, showed the identities to be authentic.

Personal records of Aleksey Minin showed his registered address as of 2011 as Ulitsa Narodnogo Opolcneniya 50, the official address in Moscow where the Military Academy of the Ministry of Defence is located. This academy is more widely known as the GRU Conservatory.
