Hackers from the Ukraine Hacker Group (UHG) have announced that they have managed to steal 14 terabytes of data from the Russian medical laboratory chain Sitilab. The leak became known on May 20. Ukrainian hackers are demanding that the network's management get in touch, threatening to publish all the stolen data if the company refuses to cooperate, the hackers wrote in their telegram channel.
UHG has already published a 1.7 gigabyte archive with contracts, scans of customer passports, and other materials.
In total, the data of almost 500,000 people has been published, but in most cases it contains only the name, date of birth, phone number, and email.
Data Leakage & Breach Intelligence (DLBI), a company specializing in information leakage, has verified the authenticity of the published data. According to the company, the merged database contains 483 thousand unique email addresses and 435 thousand unique phone numbers.
Earlier in April, DLBI reported that hackers from UHG had published data from the kassy.ru entertainment ticketing service. The text files contained applications and registered users – more than 30 thousand records.
In total, in the first four months of 2023, at least 75 cases of data leakage from commercial and government organizations were recorded in Russia.
As a reminder, the United States and its allies have exposed a large-scale network of Russian hackers that had been operating under the wing of the FSB for about 20 years.
