Pedestrians walk past the branch of Alfa Bank, Russia's largest private bank, in Moscow on April 7, 2022. - The United States announced sanctions on two of Putin's daughters, saying family members are known to hide the Russian president's wealth.

A Ukrainian intelligence authority even claimed that the cyberattackers were backed by the top counterintelligence agency of the European country. 

Largest Private Russian Bank Targeted by Ukrainian Hackers

NPR said that a Ukrainian intelligence official said that the country's SBU (Security Service of Ukraine/Sluzhba Bezpeky Ukrayiny) helped the hacktivists that attacked the Alfa-Bank. 

The source requested anonymity because the information he discussed was very sensitive. What this official shared is aligned with what KibOrg and NBL claimed. 

The two Ukrainian hacking organizations posted a blog with screenshots. They claim that these images were from the internal database of Alfa-Bank. 

Aside from this, the two Ukrainian hacktivists also shared personal details of some Russian individuals. They added that the database they breached allowed them to access over 30 million records of Alfa-Bank's clients. 

These sensitive details include account numbers, phone numbers, birthdates, as well as names. KibOrg and NBL didn't share additional details regarding the breach they made against the largest private Russian bank. 

But, they said that they would be sharing the data they obtained from the Russian financial firm with investigative journalists.

An engineer from the Israeli company "Commun. it" used his expertise in social media commercial analysis to identify networks of fake users at the group's office in the Israeli city of Bnei Brak near Tel Aviv on January 23, 2019. - A coalition of Israeli diplomats, programmers, and hackers have joined forces to stave off threats.

Aside from NBL and KibOrg, another Ukrainian hacktivist group called "IT Army" claimed that it was able to conduct significant DDoS (distributed denial-of-service) attacks against Leonardo; a Russian local airline booking system. 

More than 50 Russian carriers are using Leonardo, as reported by SC Magazine. Since this Russian booking system is critical for the country's airline industry, the DDoS intrusion drastically affected the flight industry of Russia. 

Experts said that the cyberattack disrupted flight operations of numerous Russian carriers, such as Rossiya Airlines, Pobeda, and Aeroflot. This just shows that Ukraine is still continuously using cyberattacks among its main counterattacks against Russia. 

Military enthusiasts said that cyber operations have been a critical tool for Ukraine in its resistance against Russia's invading forces.  If you want to learn more about the latest Ukrainian cyberattacks against Russia, you can click here.
