Ukrainian and German legislation enforcement authorities have recognized two Ukrainians suspected of working for the Russia-linked ransomware-as-a-service (RaaS) group Black Basta.
As well as, the group’s alleged chief, a 35-year-old Russian nationwide named Oleg Evgenievich Nefedov (Нефедов Олег Евгеньевич), has been added to the European Union’s Most Needed and INTERPOL’s Pink Discover lists, authorities famous.
“In accordance with the investigation, the suspects specialised in technical hacking of protected methods and had been concerned in getting ready cyberattacks utilizing ransomware,” the Cyber Police of Ukraine mentioned in a press release.
The company mentioned the accused people functioned as “hash crackers,” who concentrate on extracting passwords from data methods utilizing specialised software program. As soon as the credential data was obtained, members of the ransomware group broke into company networks and finally deployed ransomware and extorted cash to get better the encrypted data.
Authorities carried out searches on the defendants’ residences positioned in Ivano-Frankivsk and Lviv, permitting them to grab digital storage units and cryptocurrency belongings.
Black Basta first emerged within the menace panorama in April 2022, and is claimed to have focused greater than 500 firms throughout North America, Europe, and Australia. The ransomware group is estimated to have earned a whole bunch of tens of millions of {dollars} in cryptocurrency from illicit funds.
Early final 12 months, a 12 months’s price of inside chat logs from Black Basta leaked on-line, providing a glimpse into the group’s internal workings, its construction and key members, and the varied safety vulnerabilities exploited to achieve preliminary entry to organizations of curiosity.
The leaked file additionally unmasked Nefedov as Black Basta’s ringleader, including he goes by numerous aliases, equivalent to Tramp, Trump, GG, and AA. Some paperwork alleged that Nefedov had ties to high-ranking Russian politicians and intelligence companies, together with the FSB and GRU.
Nefedov is believed to have leveraged these connections to guard his operations and evade worldwide justice. A subsequent evaluation from Trellix revealed that Nefedov was in a position to safe his freedom regardless of getting arrested in Yerevan, Armenia, in June 2024. His different aliases embrace kurva, Washingt0n, and S.Jimmi. Though Nefedov is claimed to be in Russia, his actual whereabouts are unknown.

It is price mentioning right here that Black Basta surfaced as an autonomous group, alongside BlackByte and KaraKurt, following the retirement of the Conti model in 2022. Different members joined teams like BlackCat, Hive, AvosLocker, and HelloKitty, all of which at the moment are now not lively.

The leaks have led to Black Basta’s obvious demise, with the group remaining silent after February and taking down its knowledge leak later that month. However with ransomware gangs identified to shut down, rebrand, and reemerge below a unique id, it will not be shocking if members of the erstwhile felony syndicate pivot to different ransomware teams or kind new ones.
Certainly, per stories from ReliaQuest and Development Micro, it is suspected that a number of of the previous Black Basta associates might need migrated to the CACTUS ransomware operation – an evaluation based mostly on the truth that there was a large spike in organizations named on the latter’s knowledge leak website in February 2025, coinciding with Black Basta’s website going offline.
