Ukrainian cyber specialists launch largest attack on Russian providers in May

This is reported by Liga.net, citing a source in the Security and Defence Forces.

The source said that the Russians call this DDoS attack by the Defence Intelligence of Ukraine the most powerful they have ever had to deal with.

According to the source, the Russian operator Miranda Media suffered the most as a result of the attack. Its subscribers had no connection and could not pay for services due to the damage to the billing system. Users of the temporarily occupied territories of Kherson and Zaporizhzhia regions, as well as Crimea, had no access to the network. 

At the same time, cyberattacks by the Defence Intelligence of Ukraine affected the Russian Farline network, primarily in Crimea.

The CEO of one of the Russian telecommunications operators, Ivan Zima, informed local media that it took Russian specialists at least 16 hours to partially restore the connection. A significant number of subscribers remained without connection for more than two days.

According to representatives of the providers, during the restoration of communication, there were difficulties in communicating with subscribers, as they refused to provide operators with their current contact information for fear of fraud.

It is noted that 20% of subscribers refused to upgrade their network equipment, which could protect them from further attacks.

The source stressed that the DIU's cyberattacks continued in June: they targeted Miranda Media, servers of propaganda media and local occupation authorities, contact centres, registration and traffic control systems on the Kerch Bridge, airport resources and network infrastructure, and payment systems.

According to the source, this caused delays in flights, significant traffic jams on the Crimean bridge, and the suspension of cash registers on the temporarily occupied peninsula.
