Hackers from the Blackjack group hack into a Russian state-owned enterprise

Hackers stole technical documentation of 500 facilities of the Russian Defence Ministry. These include weapons arsenals, anti-aircraft missile sites, headquarters, and barracks, the Ukrainian public broadcaster reports.

They hacked into a Russian state-owned enterprise that builds military facilities throughout Russia. The hackers downloaded over 1.2 TB of data from Russia's Main Military Construction Directorate for Special Objects.

The hackers also hacked into seven servers and encrypted more than 150 computers of the institution's employees. Russian special builders were left without the entire data set and backup copies of information.

Previously, hackers from the Blackjack group hacked into the Moscow-based Internet provider M9com and destroyed its servers. It's about 20 terabytes of deleted data: the company's official website, branch websites, mail server, cybersecurity services, etc. The cyber-attack left some residents of the Russian capital, Moscow, without internet or television.
