A pro-Ukraine hacktivist group named 'Blackjack' has claimed a cyberattack against Russian provider of internet services M9com as a direct response to the attack against Kyivstar mobile operator.
Kyivstar is Ukraine's largest telecommunications service provider and its services were severely disrupted in mid-December by what was later revealed to be an attack from Russian hackers.
An investigation of the Security Service of Ukraine revealed that the Russians initially breached Kyivstar in May last year and had been preparing for the attack in December that culminated with simultaneous wiping of thousands of virtual servers and computers.
"Hacker attack on M9com is just a continuation of the series of warm-up acts of retribution for the civilian Kyivstar before the big bada-boom" - Blackjack hacker group.
Russian hackers wiped thousands of systems in KyivStar attack.
