Advisory Summary

WD Discovery versions prior to 4.4.396 were installing a Windows 7-compatible driver on Windows 10 systems that prevented the Windows 10 Memory Integrity option from being enabled. Memory integrity is a feature of core isolation that prevents malicious code from accessing high-security processes in the event of an attack. WD Discovery version 4.4.396 addresses this issue by replacing the driver with one that is compatible with Memory Integrity. In either case, old or new driver, there was no impact to normal hard drive operation.

Reported By: Western Digital would like to thank Aaron LeMieux of Microsoft for reporting this issue.

WD Discovery software executable files were signed with an unsafe SHA-1 hashing algorithm. This has been updated to the SHA-256 hashing algorithm to support secure code signing.
