‘Comrade Major’. An anonymous Telegram channel leaked the personal data of 3,000 ‘Navalny supporters.’ Here’s how it happened and who was behind it.

On Friday, August 9, a day before a massive political protest at Sakharov Prospekt in Moscow, the Telegram channel Comrade Major (@MayorFSB) wrote the following: “Listen to this: these idiots in the Team Navalny chat group have completely lost it. Right in their chat group, they accidentally uploaded the WHOLE database of their supporters’ information that they use for mobilizing people for rallies. It’s got everything: passport and telephone numbers, addresses, everything! There’s not even anything left for us to do! These guys screwed themselves over. Jesus, what a bunch of idiots!”
