Installer SCSRVC.EXE

Jump to solution

I've been getting quite a few message like this:

Installer scsrvc.exe was blocked from modifying AdSSO.msi in Enabled mode.

 

The file that it is modifying is not the same.  We also see the behavior in Observation mode.  We've created rules to allow the EXE to modify files but it doesn't seem to be working.

Please advise.

Yes, i would go through that product guide. And read the section highlighted. 

 

The feature you are running into is Package control. It is how you allow installers in your systems.

You can add them manually or run a server task "Scan a software repository" to add the installers/certificates.

Can you show the EPO event. Or the block in the s3diag from the client.

Interesting.  I can find the event but it isn't from scsrvc.exe.  It's from the user:

<PKG_MODIFICATION_PREVENTED file_name="C:\Users\username\AppData\Local\Temp\{70C9DC49-56CF-4A69-80D4-8A4D8A31FCA9}\HPZBDI64.msi" pid="22416" process_name="c:\windows\system32\rundll32.exe" ppid="11900" parent_process_name="c:\windows\explorer.exe" cksum="14706f3a1724219ab925d2eaed483715a82100e0" cksum256="14a820d22f28e58eca969b595bb4920e4e073a41da8e2e1a37ed1819512e8165" event_time="1603268368674" event_time_system="Oct 21 2020:08:19:28" user_name="domain\username" />

The only place that I can find it is when it shows up in Policy Discovery (see the attachment).

Have you added HPZBDI64.msi to the installers tab under Solidcore Rules > Installers?

No. Is that something we should be doing? We're still relatively new to MACC (only a couple thousand in enable mode) so we're still learning.
