Create exclusion on Registering of programs to autorun
I was thinking if is possible to create exclusion for this hit:
Threat Target File Path: HKCU\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN\YAMMER\"C:\Users\obfuscated\AppData\Local\yammerdesktop\update.exe" --processStart "Yammer.exe"
Description: USER ran C:\Windows\System32\reg.exe, which accessed HKCU\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN\YAMMER, violating the rule "Registering of programs to autorun". Access was allowed because the rule wasn't configured to block.
as we are using YAMMER in our organization, it creates lots of useless logs in our ePO.
We would like to still create log for others programs registered to autorun. Thats why the reg.exe can't be excluded.
You should be able to go in Access Protection Policy, "Endpoint Security Threat Prevention : Policy Category > Access Protection > Your_Policy" and under "Rules" section, you should be able to find "Registering of programs to autorun" rule.
There you may select the rule and modify it by clicking on "Edit" button and under "Executables:" section you may specify "Add" what you want to be excluded, just make sure that "Exclude" is selected under "Inclusion status:".
Please note general suggestion: When ever you are creating new or modifying existing AP rule, the best practice is always to configure rule to report only and than evaluate what that rule is actually blocking to make sure that the rule will not block some of essential system functions.
Once you are sure that the AP rule will not block anything other than what you wanted it to block then you can enable block on couple non-critical test machines first, before you enable it across the environment.
I hope this helps and please, please, please make sure to always perform report -> evaluate -> block, otherwise, AP rules are so powerful that they get you lot of trouble if not configured properly.
