Hackers from the Blackjack group hack into Moscow internet provider M9com

Hackers from the Blackjack group, believed to be working with the Security Service of Ukraine, have hacked into the Moscow-based internet provider M9com and destroyed its servers.

This was reported by the Ukrainian public broadcaster Suspilne.

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.

The hackers also downloaded more than 10GB of data from the company's mail server and client databases, which they made available to anyone who wanted to see it.

According to Suspilne's sources, the hackers are preparing larger attacks to "take revenge" for the cyber attack on Ukrainian operator Kyivstar on December 12.

Earlier, representatives of the Security Service of Ukraine said that Russian hackers had been in the system of the Ukrainian telecommunications giant Kyivstar since at least May last year.
