Following the death of opposition leader Alexey Navalny in a Russian prison in February, a group of anti-Kremlin hackers took action to seek revenge. These hackers gained access to a computer network linked to Russia's prison system and proceeded to deface a prison contractor's website with a photo of Navalny, along with a message expressing support for him.
In a significant breach of security, the hackers also claim to have stolen a database containing information on hundreds of thousands of Russian prisoners and their contacts, including those in the penal colony where Navalny passed away. The hackers, comprising a mix of nationalities including Russian expatriates and Ukrainians, are sharing this data in hopes of shedding light on Navalny's circumstances.
