I have installed a new environment with
VSE 8.8 Patch 8
I set "Block unknown files". After modify the putty.exe (change one letter for a new hash) the file is unknown and is blocked on the client
The ATD analyses the file and set the ATD reputation to "Might be Trusted" (view in TIE Reputation).
I run the modified putty.exe again and the file is always blocked.
Why? Is this a wrong behavior?
• After analysis, McAfee Advanced Threat Defense will publish the file’s reputation to the DXL. At that point, the endpoint (and all other products on the DXL) will be notified if it is malicious or safe.
• McAfee recommends configuring the TIE client to block the execution of files if they are sent to ATD. This will result in TIE blocking the execution of the file on the endpoint even if ATD later concludes that they are safe. In that case, the end user would simply have to run the file again to execute it.
I upgraded the ATD to version 3.8. I hope the new DXL client version 3.0 in ATD 3.8 Image resolve my issue, but its the same behavior. Known Files are blocked by TIE
