Anti-Exploit causes program crashes

[kieferschild]

Good morning,

We have a couple of users at different companies who are using Malwarebytes with Symantec Endpoint Protection Cloud.

It seems that MBAE is causing Symantec extensions in web browsers and Outlook to crash which In turn causes the program to crash.

Disabling MBAE seems to have stopped the problem but it's not a fix.

Thanks,

Hey Kieferschild,

 

I am assuming they are not causing an alert when this occurs, correct? If possible, can you collect the logs from this link:

If you are not comfortable posting the FRST logs in the post, feel free to PM me them.

Hey Kieferschild,

 

Thank you for the logs. Just to confirm, can you make sure these are in Symantec, don't want this to be because of our normal files:

• C:\Program Files\Malwarebytes Anti-Exploit\mbae.exe
• C:\Program Files\Malwarebytes Anti-Exploit\mbae-svc.exe
• C:\Program Files\Malwarebytes Anti-Exploit\mbae-cli.exe

For x64 installations:

• C:\Program Files (x86)\Malwarebytes Anti-Exploit\mbae.exe
• C:\Program Files (x86)\Malwarebytes Anti-Exploit\mbae-svc.exe
• C:\Program Files (x86)\Malwarebytes Anti-Exploit\mbae-cli.exe

Since it is crashing, do you know if these are creating memory dump files? If possible, can you use the instructions here to get one to generate on the on one of the processes that is crashing:

Hi,

Symantec have also advised that I excluding the following:

 

• C:\Program Files\Symantec.cloud\
• C:\ProgramData\Norton\
• C:\Windows\System32\drivers\NISx64\
• C:\Windows\System32\drivers\NISx86\

I've added them under "Ignore List" - Do I need to add them anywhere for MBAE?

Hey Kieferschild,

 

For mbae's ignore list, we only accept md5's for the exclusion and they only need to be inserted if a block occurs to prevent it from occurring once more. We don't scan the file system directory with mbae like with MBAM so you wouldn't need to add those anywhere. We just monitor what tries to hook or interact with our protected processes.
