Gravity Zone Software Execution Policy Bypass

Hi guys, all right? During the last week, I've been testing some features of GravityZone and one of them was the program execution blocking policy.

From what I verified, we can block the execution of a software both by the absolute path and by the Hash (MD5/SHA).

I used an EDR test file without changes and it was blocked; however after I used the program "MD5-Hash-Changer" to change the hash value of the .exe, I was able to run it without major problems.

Is there any way to counter this technique?
