Hackers from the Blackjack group, allegedly related to the Security Service of Ukraine (SBU), hacked the Moscow Internet provider M9com and demolished its servers, an informed source told Interfax-Ukraine on Tuesday.
“We are talking about 20 TB of deleted data: the company’s official website, branch websites, mail server, cyber protection services, and so on. As a result, some Moscow residents were left without the Internet and television,” the agency’s interlocutor said.
Data from the company’s mail server and client databases were also posted online. Hackers called the attack on M9com a “warm-up” as part of a retaliation campaign for a hacker attack on the servers of the Ukrainian mobile operator Kyivstar.

LONDON: Hackers linked to Ukraine’s main spy agency have breached computer systems at a Moscow-based internet provider in retaliation for a Russian cyber attack against Ukrainian telecom giant Kyivstar, a source with direct knowledge of the operation told Reuters on Tuesday.
The hacking group, dubbed “Blackjack”, has previously been linked to the Security Service of Ukraine (SBU). The hackers deleted 20 terrabytes of data at M9 Telecom, a small Russian internet and TV provider, leaving some Moscow residents without internet, the source said.
The digital intrusion was a warm-up for a larger cyber attack which would be “serious revenge for Kyivstar”, the source said, citing the hackers. The source did not say when the hack took place.
M9 Telecom did not respond to an emailed request for comment. The company’s website was still online on Tuesday, despite claims by the hacking group that it had been destroyed.
Reuters was unable to independently verify the extent to which the hack was successful. Reached by phone, M9 Telecom’s CEO Andrey Pavolvsky declined to comment.
Kyivstar, Ukraine’s largest mobile network operator, was knocked offline by Russian spies last month in what appeared to be the largest cyber attack since Moscow launched its war on the country in February 2022.
Russian hackers were inside Kyivstar’s systems for months before the attack, Ukraine’s cyber spy chief, Illia Vitiuk, told Reuters last week. The hack caused “disastrous” destruction at the company, he said.
Separately, Ukraine’s military intelligence agency, the GUR, said late on Monday that it had received a large cache of classified Russian military data from the Special Technology Centre (STC), a sanctioned Russian company which produces the Orlan drone and a range of intelligence equipment for Moscow.

Sources reportedly tipped off Ukraine media to a cyberattack launched this week by the Blackjack cyber group, linked to the Security Service of Ukraine (SBU), that they claim was able to “destroy” the servers of Moscow Internet service provider M9 Telecom.
The ISP’s website was operational on Jan. 9.
Unnamed sources told state-run Ukrainian media outlet Ukrinform that the cyber operation was in retaliation for the Russia-backed breach of Kyivstar mobile phone operator Dec. 12, which caused communications blackouts across Ukraine. The source reportedly added the M9 Telecom cyberattack was just a “warm up” for more “serious revenge for Kyivstar.”
The Blackjack cyber group likewise claimed credit for the late December breach of Moscow’s Rosvodokanal water utility, which the group claimed it was able to pull off with the help of the SBU.
Earlier this month, the SBU’s cyber chief, Illia Vitiuk, warned that Russia’s compromise of Kyivstar, a modern, private company should signal to Western countries that nothing is beyond the reach of sophisticated Russian cyber threats.

Hackers from the Blackjack group, allegedly affiliated with Ukraine’s SBU security service, have hacked into Moscow’s M9com internet provider and demolished its servers, informed sources told NV on Jan. 9.
The attack concerns 20 terabytes of deleted data: the company’s official website, branch websites, mail server, cyber security services, etc.
“As a result, some Moscow residents were left without internet and TV,” the sources said.
“The hackers also downloaded more than 10 GB of data from the company’s mail server and client databases, which they made available for anyone to examine.”
