Ukrainian hackers leaked data of millions of customers of Russian Alfa Bank

The Ukrainian hacker group KibOrg has posted the complete client base of Alfa-Bank in the public domain, moscowtimes.eu reports.

Hackers gained access to this data in October 2023, publishing information about 44,000 customers. Now they have leaked personal data, including full names, dates of birth, phone numbers, cards and accounts of more than 24 million individuals who are bank customers and more than 13 million more data on legal entities.

At the same time, the bank did not answer journalists' questions about whether their clients' cards would be reissued after the leak.

Alfa-Bank publicly denies the hack. KibOrg claims that a Ukrainian prankster under the pseudonym Yevhen Volnov managed to reach one of the bank's owners, Mikhail Fridman, and he commented on the hack with the words "Well, let it go."

Earlier, KibOrg hackers reported the hacking of the database of the Russian company Sirena-Travel, which contains information about airline passengers: information about flight numbers, airlines, fares, routes, bookings and ticket prices covering the period from 2007 to 2023. The hackers made 3 million records out of more than 4 billion publicly available.

In early March last year, hackers leaked the data of nearly 50 million users of Sberbank's "Thank You" bonus program. The SberPravo service with 115,000 phone numbers and the SberLogistics service with 679,000 unique phone numbers were also hacked.

In the summer, a multimillion-dollar database of Russian Post users was leaked online, containing 10 million lines with customers' names, phone numbers, city of residence, parcel number, and time of shipment.

Also in November 2023, 1.7 million records of personal data of visitors to the FIFA World Cup in Russia were leaked. In addition, 550 million test results from the Hemotest laboratory, a 2016 blacklist of Russians for banks with 22.9 million lines, and data on 4.1 million intercity bus tickets sold in 2021 were made public.
