.restorebackup Ransomware Decryption & SQL Server Database Recovery, Professional Emergency Data Restoration Services

Incident Summary

The client’s server was compromised by the .restorebackup ransomware, which encrypted all production files and altered their extensions. This variant specifically targets backup files and databases to force ransom payments. The company’s ERP system was completely offline. However, upon forensic inspection of the 25 GB database file, our engineers discovered that while the file was corrupted, the internal data pages remained highly intact.

Technical Analysis

Forensic analysis of the .restorebackup encryption behavior revealed:

Targeted Corruption: The ransomware primarily focused on the file headers and structural pointers, leaving large segments of the data payload recoverable.

Structural Integrity: The internal schema of the SQL 2017 database was identified as stable during sector-level scanning.

Recovery Potential: Utilizing the Excellent SQL Database Recovery Tool, our team determined that the database blocks could be manually rebuilt to bypass the encryption layer.

Recovery Solution

The recovery strategy utilized a block-rebuilding extraction method. Since the .restorebackup virus corrupted the file system’s ability to read the database, our engineers worked directly with the raw data blocks. By reconstructing the encrypted segments and repairing the internal database pointers, we were able to extract the relational data into a fresh, clean environment.

Recovery Process

Forensic Integrity Scan: Deep analysis of the 25 GB SQL file to map the distribution of .restorebackup encryption.

Encrypted Block Reconstruction: Manual repair and rebuilding of the corrupted database sectors and file headers.

Advanced Data Extraction: Using specialized tools to pull tables, records, and stored procedures from the damaged .MDF file.

Schema Validation: Mounting the recovered data into a new SQL 2017 instance to verify relational consistency.

ERP Functionality Test: Final confirmation that the restored database is fully compatible and ready for production use.

Recovery Results

Recovery Integrity: Near 100%

Recovered Files: SQL Server 2017 Primary Data Files

System Status: Fully restored; ERP system returned to normal operation.

Total Recovery Time: 5 Hours
