BlackBit Ransomware: A Hidden Threat Linked To LokiLocker

BlackBit is a LokiLocker-derived ransomware discovered in September 2022 that implements persistence (copies to ProgramData and Startup, Task Scheduler entry), defense evasion (disables Windows Defender, firewall, Task Manager; deletes shadow copies and backups), process/service termination, and file encryption (excluding .exe/.dll/.sys) while appending a .BlackBit extension and continuing to monitor and encrypt newly created files; the report contains sample hashes, registry artifacts, ransomware behavior including a Persian-language kill-switch, and recommended mitigations.
