The Russian Agricultural Bank also reported being targeted by a DDoS attack on Tuesday. However, the bank noted that the impact was minimal due to their implementation of an enhanced system to combat such attacks. Gazprombank, the third-largest private bank in Russia, faced difficulties with its app’s transaction services due to the attack, though the issue was quickly resolved.
Other banks, including Alfa Bank, Rosbank, and Post Bank, were also reportedly affected.
On Wednesday, Ukraine’s military intelligence (HUR) claimed responsibility for the DDoS campaign targeting the Russian banking sector. An anonymous source within HUR, speaking to Ukrainian media, mentioned that the attacks also affected several Russian payment systems and large telecom operators such as Beeline, Megafon, Tele2, and Rostelecom. While this claim has not been independently verified, the HUR official stated that the attack “is still ongoing and far from over.”
This incident is part of a series of cyberattacks by Ukrainian entities against Russian targets. In October, pro-Ukrainian hackers and Ukraine’s security service (SBU) claimed to have breached Russia’s largest private bank, Alfa-Bank. In January, data allegedly belonging to 30 million Alfa-Bank customers was released by attackers involved in the breach. Earlier this year, the hacker group Blackjack, in cooperation with the SBU, breached a Moscow internet provider in retaliation for a Russian cyberattack on Ukraine’s largest telecom company, Kyivstar.
While not all reports from Ukrainian hackers or intelligence officials can be independently verified, the recent DDoS attacks on Russian banks had noticeable consequences, despite Russian claims of minimal impact. DDoS attacks are generally easier to mitigate, but this campaign stands out for its broad impact on multiple financial institutions and service providers.
The ongoing cyber warfare between Ukraine and Russia underscores the escalating digital conflict between the two nations. Both sides have been leveraging cyber capabilities to disrupt each other’s critical infrastructure.
The recent attacks highlight the necessity for robust cybersecurity measures and swift response strategies to minimize the impact on essential services and ensure the security of digital transactions. As cyber threats evolve, both nations will likely continue to enhance their defenses to protect against such incursions.
