Ukrainian hackers reveal Russian military secrets: devastating 1.32 trillion GB data leak

The Ukrainian service, Hromadske, reports that the Blackjack group likely has ties with the Ukraine Security Service. A source from law enforcement revealed to the service that the intruders pilfered technical documentation about 500 facilities under the Russian Ministry of Defense.

The intruders extracted over 1.32 trillion GB of data from the servers of the Main Directorate of Military Construction. The stolen data is classified, covering details of weapon arsenals, locations of anti-aircraft missile complexes, barracks, and various unit headquarters. This information involves existing and projected military facilities in Russia and occupied territories, indicating plans for new construction and modernization projects.

Going beyond the heist of technical and project documentation, the Blackjack hackers also encrypted more than 150 computers used by employees of the Russian outfit, causing a halt in construction work at military facilities across Russia. The companies fulfilling orders for the occupying army were left without much data and backup copies. Now, they either have to begin several tasks from scratch or attempt to recreate the documentation from memory.

The hacker collective Blackjack draws its name from the card game, where success requires luck and skill. Though there isn't much credible information about the group or its members, connections to Ukrainian intelligence are evident.

Blackjack recently attacked Moscow's internet provider, M9com. The assault led to damage to the operator's servers. Following this incident, the hackers warned that this action was a precursor to the "real revenge" they intended on the Russians for assaulting the Ukrainian network operator, Kyivstar.
