Issue with the Encrypted Device Restore Utility for Kaspersky Endpoint Security 10 SP2, SP2MR1, and SP2MR2 for Windows

This article concerns the following versions of Kaspersky Endpoint Security 10 for Windows:

  • Service Pack 2 Maintenance Release 2 (10.3.0.6294)
  • Service Pack 2 Maintenance Release 1 (version 10.3.0.6294)
  • Service Pack 2 (version 10.3.0.6294)
 
 
 
 

User data that has been encrypted with Full Disk Encryption (FDE) can be corrupted if you decrypt it to the original drive using the Encrypted Device Restore Utility (FDERT) version 10.3.0.6294 that is included with Kaspersky Endpoint Security 10 SP2, SP2MR1, SP2MR2 for Windows. 

We do not recommend using the FDERT utility version 10.3.0.6294 to decrypt data.

Reason

In FDERT version 10.3.0.6294, an error has been found that causes a memory leak while the utility is running. If this error occurs while decrypting a drive, user data will be corrupted. Only a part of the data will be decrypted, while the rest will remain encrypted.

Solution

Use the FDERT utility version 10.3.3.275, included with Kaspersky Endpoint Security 10 SP2MR3 for Windows, to decrypt data that has been encrypted with FDE in Kaspersky Endpoint Security 10 SP2, SP2MR1, SP2MR2 for Windows (version 10.3.0.6294).

Recommendations

The procedure for decrypting data to the original drive is unreliable. If a software or hardware error occurs, the data on the drive will be corrupted. We therefore recommend:

  • Doing a full sector-by-sector backup of data before decrypting a drive using the FDERT utility.
  • Using transparent data access instead of decryption.
