Decrypt LockBit 3.0 SQL Files

My Microsoft SQL Server data files were locked during a recent LockBit 3.0 (Black) incident and I need them brought back to a usable state. I already have the official decryptor and key; what I’m missing is someone who knows exactly how to apply them without risking further damage and who can prove the database is intact once the process is finished.

You will work with copies of the affected .mdf and .ldf files (about 120 GB in total) on an isolated workstation or a secure remote session, run the LockBit tool with the key I provide, and then attach the results to SQL Server (2019) to confirm integrity—DBCC CHECKDB should return clean. Once verified, I’d like the database packaged as a working backup set or simply left attached on the server, ready for production.

Deliverables:
• Fully decrypted SQL Server files (.mdf/.ldf)
• Brief report outlining the exact steps, commands, and validation checks performed
• Confirmation that the database opens and passes integrity checks without errors

If you have prior experience with LockBit or similar ransomware strains and understand SQL Server internals, let’s get started right away. Confidentiality is essential; I’m happy to sign an NDA if needed.
