🧠 Our Top 20 Techniques for Ransomware Decryption & Data Recovery

1. Ransomware Identification
   Analysing encrypted file extensions, ransom notes, and encryption patterns to determine the ransomware strain.
2. Known Decryptor Matching
   Using secure repositories and tools to match the strain with publicly available decryptors (when applicable).
3. Custom Scripted Decryption
   Writing custom scripts for partial or flawed encryption algorithms.
4. Brute Force Key Recovery
   Exhaustive key permutation methods for weakly encrypted data sets.
5. Forensic File Carving
   Extracting raw file signatures from encrypted drives where metadata is lost.
6. Recovery via Shadow Copies
   Attempting to restore from Volume Shadow Copies, if untouched by the attacker.
7. Partition & File System Repair
   Repairing corrupted partitions to regain access to encrypted or partially encrypted files.
8. Partial File Reconstruction
   Rebuilding usable file content from partially encrypted or fragmented files.
9. Mirror and Backup Recovery
   Analysing alternate storage locations, disk clones, and backups for unencrypted data.
10. Block-Level Analysis
    Deep forensic block-by-block inspection of encrypted volumes to identify accessible data areas.
11. System Rollback Recovery
    Attempting recovery via safe rollback where system restore points are available.
12. Network Drive & Cloud Sync Restoration
    Examining cloud-synced services (OneDrive, Dropbox) for pre-encrypted file versions.
13. Log File Forensics
    Investigating file access history and encryption timelines for file recovery prioritisation.
14. Encrypted File Header Mapping
    Reconstructing known file headers and footers (e.g., for PDFs, JPEGs, DOCX).
15. Decryption via Private Key Negotiation
    In rare cases, working with clients to legally and securely negotiate for decryption keys.
16. Comparative File Analysis
    Comparing infected and clean file samples to reverse-engineer the encryption logic.
17. Ransomware Flaw Exploitation
    Identifying weaknesses in known ransomware encryption routines.
18. Registry & Temp File Analysis
    Extracting key material or executable paths from local registry hives and temp folders.
19. Live RAM Capture and Analysis
    Analysing live memory snapshots for decryption keys left in RAM during encryption.
20. Manual Hex-Based Recovery
    Using low-level hex editors to identify recoverable segments within encrypted files.
