Carbon Black EDR (formerly Cb Response)

Issue/Introduction

  • Attempting To Ban MD5 Hash Or Hashes
  • Receive Error Message That Hashes Are Unrecognized
  • Hashes Do Not Appear On Banned List If Duplicate Hash Listed

Environment

  • Carbon Black Response Console: All Versions
  • Carbon Black Response Server: All Versions

Cause

Current limitation in the product where the UI does not do any check as to whether the list contains any duplicates. There is one call made to the banning API per hash. This means that although each unique hash does get banned successfully, the calls for duplicate hashes fail.

Resolution

This will be resolved in a future product release.
