A top hacker-hunter at Russia's largest cybersecurity firm has been arrested on charges of treason

A key cybercrime investigator at Russia's biggest cybersecurity firm, Kaspersky, was arrested on charges of treason last month, Russia's Kommersant newspaper reported on Wednesday.

Kaspersky Lab confirmed to the Associated Press that Ruslan Stoyanov, head of its computer incidents investigations unit, was arrested in December.

Stoyanov was arrested along with a senior Russian FSB intelligence officer, Sergei Mikhailov, according to Kommersant. Mikhailov, who also faces treason charges, was the deputy head of the information security department of the FSB, Russia's national security service.

Investigators are examining money that Stoyanov allegedly received from foreign companies or entities, according to Kommersant. A source told the paper that the case has been filed under article 275 of Russia's criminal code, which allows the government to prosecute an individual suspected of aiding a foreign state or organization.
