Ukrainian and German authorities identified two Ukrainian suspects working for Black Basta ransomware group and added alleged leader Oleg Nefedov to EU Most Wanted and INTERPOL Red Notice lists. The suspects specialized in hash cracking to extract passwords and enable ransomware deployment. Black Basta, which emerged in 2022 and targeted over 500 companies, went silent after internal chat logs leaked in early 2025, revealing its structure and Nefedov's leadership. Evidence suggests former Black Basta members may have migrated to the CACTUS ransomware operation following the group's collapse.
