This case study documents the successful recovery of a Microsoft SQL Server 2008 database following a sophisticated attack by the .PsLxRQPsA ransomware. By applying advanced block-level reconstruction techniques, our engineering team restored critical business intelligence and resumed ERP functionality without the need for a decryption key.

Client & Data Information

• Client Name: Confidential
• Data Type: SQL Server 2008 (.MDF / .LDF)
• Data Capacity: 25 GB
• Ransomware Extension: .PsLxRQPsA

Incident Summary

The client’s server environment was compromised by the .PsLxRQPsA ransomware, a variant known for complex file renaming and encryption. All production files were rendered inaccessible, causing a total halt of the client’s ERP operations. Upon initial evaluation, forensic testing revealed that while the file system was heavily damaged, the internal data pages of the 25 GB SQL database remained largely intact.

Technical Analysis

Forensic analysis of the .PsLxRQPsA infection identified several critical recovery pathways:

• Structural Integrity: The ransomware primarily targeted file headers; however, the core database pages showed a high degree of integrity.
• Encryption Behavior: The .PsLxRQPsA variant used a predictable encryption offset, allowing our tools to identify and “rescue” non-encrypted data blocks.
• Advanced Extraction: Using the Excellent SQL Database Recovery Tool, we confirmed that the relational schema could be fully reconstructed by rebuilding the damaged blocks.

Recovery Solution

Our engineers implemented a surgical extraction strategy. Rather than attempting to decrypt the entire operating system, we focused on the 25 GB database file. By rebuilding the specific encrypted blocks and correcting file pointers, we successfully migrated the raw data into a clean, functional database environment.

Recovery Process

• Forensic Mapping; Detailed scan of the .PsLxRQPsA encrypted file to locate recoverable data segments.
• Encrypted Block Reconstruction: Manual and automated repair of the corrupted database blocks within the .MDF file.
• Data Extraction & Export: Pulling tables, stored procedures, and relational data from the damaged container.
• Database Integrity Validation: Mounting the recovered data in a clean SQL 2008 environment to ensure 100% consistency.
• ERP System Integration: Final verification ensuring the database is immediately usable by the client’s ERP software.

Recovery Results

• Recovery Integrity: Near 100%
• Recovered Files: SQL Server 2008 Primary Database Files
• System Status: Fully restored; business operations resumed immediately.
• Total Recovery Time: 2 Hours

Expert Reminder from Shenzhen Excellent Data Recovery Center: Regular off-site backups are the best defense against ransomware. If your server is infected by the .PsLxRQPsA virus, contact professionals immediately. We provide a 100% original database recovery guarantee for specific failures, regardless of database size.
