Hackers troll prosecutor's office in advance of Russia Day protests
Hundreds were detained at the March 26 rallies, the largest protest held in Russia since 2011-12
 "Vladimir Putin, Dmitry Medvedev, Russia, Kremlin, Moscow")
Russian Prime Minister Dmitry Medvedev, left, and President Vladimir Putin walk after the President delivered his annual state of the nation address in the Kremlin in Moscow, Russia.
On the eve of Monday's nationwide anti-corruption protests, that was scheduled to coincide with Russia Day, hackers broke into the Yaroslavl Region Prosecutor's Office's website and posted a joking message: “Stay at home. Or we'll put you in jail instead of Dimon.”
Dimon is a nickname for Prime Minister Dmitry Medvedev that became widely used after opposition leader Alexei Navalny's Anti-Corruption Foundation released a film entitled “He Is Not Dimon to You,” on March 2. The film details corruption among top Russian officials, including Medvedev, and served as the catalyst for protests held across Russia on March 26.
The hackers’ embedded the “He Is Not Dimon to You” YouTube video on the Prosecutor's Office website, adding: “The Prosecutor's Office calls on citizens not to yield to provocations and to stay away from the unsanctioned events!”
