Our Ransomware Recovery Services
We address a wide spectrum of ransomware infections and scenarios, providing technical investigation and data recovery through a structured, forensic-based approach.
Ransomware Types We Handle
- Common and Advanced Variants: Including WannaCry, LockBit, REvil (Sodinokibi), Dharma, Conti, BlackCat, and more.
- Encryption Algorithms: AES, RSA, Salsa20, ChaCha20 and hybrid encryption structures.
- Targeted File Systems: NTFS, FAT32, exFAT, HFS+, APFS, EXT3/4, XFS, ReFS, ZFS.
Technical Recovery Process for Ransomware-Infected Devices
Each recovery is tailored to the attack type, device configuration, and encryption method. Below are key techniques we employ during ransomware data recovery:
1. Ransomware Variant Identification
- Process: Using digital signatures, header analysis, and encrypted file extensions, we determine the exact ransomware strain.
- Purpose: Enables matching known decryption keys or exploiting known flaws in the malware.
2. Decryption Tool Deployment
- Process: We apply verified decryption tools when available for specific ransomware variants.
- Purpose: Recover files with minimal data loss, preserving folder structure and file integrity.
3. Brute Force and Key Search
- Process: We perform brute-force attacks on weak encryption implementations or search for leaked keys through forensic analysis of RAM dumps and shadowed memory areas.
- Purpose: Useful for recovering data from outdated or poorly coded ransomware.
4. Partial File Reconstruction
- Process: In cases of partial encryption, unencrypted data fragments are analysed and reconstructed using binary comparison and header repair tools.
- Purpose: Restore partially affected files such as documents, spreadsheets, and media files.
5. Shadow Copy and Volume Snapshot Recovery
- Process: We scan for intact Windows Volume Shadow Copies (VSS) or hidden system restore points.
- Purpose: Restore earlier versions of files or system states prior to the attack.
6. File Carving from Unallocated Sectors
- Process: Deep scan of the drive’s unallocated space to recover deleted or hidden file remnants using file signature recognition.
- Purpose: Recover data that was deleted by the ransomware before or during encryption.
7. Forensic Metadata Reconstruction
- Process: Extract and rebuild file metadata (timestamps, ownership, directory paths) even when the file content is encrypted.
- Purpose: Aid in identifying affected files and reconstructing directory structures post-recovery.
8. Disk Imaging and Preservation
- Process: Sector-level imaging of all infected storage media to protect original data from further damage.
- Purpose: Enables safe recovery from working copies without risking data integrity.
9. RAID-Specific Ransomware Recovery
- Process: In RAID environments, we first rebuild the virtual RAID configuration from disk members before applying ransomware recovery methods.
- Purpose: Ensures full logical reconstruction before tackling encrypted data.
10. Negotiation Support and Analysis
- Process: For extreme cases, we provide forensic assistance in safely contacting threat actors (via third-party legal representatives if applicable).
- Purpose: Used only when other decryption avenues have been exhausted and client-approved.

Contact Our Forensic Ransomware Team
If your data is encrypted due to a ransomware attack, do not reboot, reinstall, or attempt recovery using free tools—these actions may make recovery impossible.
