Ukrainian hackers disrupt major Moscow Internet provider, also cutting off TV services

Ukrainian hackers from the Blackjack group, which is likely associated with the SBU security service, hacked the Moscow-based Internet provider M9com and deleted data, a law enforcement official told LIGA.net.

Hackers reportedly deleted 20 TB of data. This includes the company's official site, branch sites, mail server, cyber protection services, etc. Because of this, some Moscow residents lost access to the Internet and television.

Blackjack also downloaded more than 10 GB of data from the company's mail server and client databases, which were made available for anyone to explore. Access to data is possible through the TOR browser.

Hackers also announced an upcoming serious attack, which will be revenge for the cyberattack on a major Ukrainian mobile carrier Kyivstar.

Earlier, the Ukrainian hacker group KibOrg published the allegedly complete database of the largest Russian commercial bank Alfa-Bank.

In October 2023, KibOrg together with NLB hackers obtained personal data of more than 30 million Russian bank customers. These are names, dates of birth, customer account and phone numbers, etc.
