Kaspersky ScraperDecryptor is a free, specialized utility developed by Kaspersky Lab to restore files locked by the Trojan-Ransom.Win32.Scraper ransomware.
While the Scraper ransomware utilizes advanced AES-256 and RSA-2048 encryption algorithms, the developers made critical implementation errors. Security researchers exploited these mathematical flaws to build this standalone decryptor, which can successfully recover user data in over 70% of infection cases without paying a ransom. Phase 1: Pre-Decryption Isolation & Cleanup
Running a decryptor on an actively infected machine is dangerous because the ransomware can instantly re-encrypt your newly recovered files.
Cut Internet Connections: Disconnect ethernet cables and turn off Wi-Fi to stop the malware from communicating with malicious Command and Control (C&C) servers.
Isolate Media: Unplug external hard drives, flash drives, and network storage to prevent lateral virus migration.
Purge the Malware: Run a thorough system scan using an antivirus utility, such as the free Kaspersky Virus Removal Tool, to fully quarantine and eliminate the primary Scraper Trojan executable. Phase 2: How to Use Kaspersky ScraperDecryptor
Once the live infection is fully removed from your operating system, you can proceed with file extraction and recovery:
Download the Tool: Secure the official, free executable by visiting the Kaspersky Free Recovery Tools Portal.
Unpack the Utility: Extract the contents of the downloaded ScraperDecryptor.zip archive into a dedicated folder on your local storage drive.
Execute: Open the destination folder and double-click ScraperDecryptor.exe.
Accept Terms: Read through the displayed End User License Agreement and click Accept. Configure Parameters: Click the Change parameters option.
Check the boxes next to the target drives you need to scan under “Objects to scan”.
(Optional) Mark the Delete crypted files after decryption checkbox under “Additional options” if you want to automatically erase the broken, encrypted duplicates after they are fixed. Click OK. Initiate Scan: Click Start scan.
Target a File: The interface will prompt you to navigate to and select the file path of at least one Scraper-encrypted file on your system to begin decoding the cryptographic sequence. Alternative Free Decryption Resources
If the Scraper tool does not resolve your particular data emergency, you are likely dealing with a completely different strain of ransomware. Do not pay cybercriminals; instead, explore alternative free public decryption catalogs:
No More Ransom Project: An international, collaborative library hosted at No More Ransom featuring dozens of free decryption keys provided by global tech firms and law enforcement.
Other Kaspersky Decryptors: Depending on the specific file extension left by the virus, look into alternative tools like Kaspersky RakhniDecryptor, RectorDecryptor, or XoristDecryptor.
