I have a customer that is running a Traps 5.0 demo (agent version 5.0.4) on Windows 10. Every time he opens particular excel, word, and visio documents, Traps flags the application because the JIT Mitigation module was tripped. I uploaded one of the excel documents that was causing the issue to Wildfire, and it came back benign.
We ended up disabling the JIT Mitigation module, but I've never seen that issue before, and I'm concerned that there may be a bigger problem with this user's system that we are missing.
Can anyone offer any guidance as to what might be tripping that module, and how I can investigate further as to the root cause?
Thanks in advance!
That behavior is beacuse the office macro analysis is much powerful in TMS than ESM (at least on version 4.0 and 3.x).
I sugest to you open the event and analyses the path and files/libraries vinculaded, then put that event on excepcion if you are completely sure that is clean or create a rule for especific host, but leave the JIT Mitagation disabled is not a best practice.
The best regards,
That was my first inclination...that macros were triggering it. However, Excel did not show any macros whatsoever associated with those files.
We had this issue too, it turned out to be an incompatibility issue running along Trend Micro OfficeScan. Support created an exception file for us to resolve the issue.
