Russian authorities have arrested Sergei Mikhailov, deputy chief at the FSB's Information Security Center (CDC), and Kaspersky exec Ruslan Stoyanov on charges of treason.
Mikhailov has been accused of receiving money from "foreign organizations," Russian daily newspaper Kommersant reports, citing unnamed FSB sources.
Mikhailov was reportedly arrested in December. His department is responsible for monitoring the Russian internet as well as investigating data leaks, although some security experts say it may also be used for offensive operations.
Russian authorities also arrested Ruslan Stoyanov (see picture), who heads the computer incidents investigations team at Moscow-based Kaspersky Lab, and who has reportedly also served as a liaison between the company and Russian security services.
