XDR and registry on windows machines

Hi all,

Got a question - can the XDR block registry changes on windows machines? I'm talking about a blanket block, not just on the agent's own registry keys.

Hi @Daniel_Itenberg ,

The only way I can think of is with custom BIOC converted to BTP.

Using XQL you should be able to build BIOC rule detecting registry change searching historical data. After that apply this BIOC as BTP so the agent can prevent it,

Hi @Daniel_Itenberg

As Aleksandar shared above you may use Custom BIOC converted to BTP for your use case however keep a note for BTP rule to take action event needs to happen and then prevention action can be taken (kill the process). Note: registry change will be success as BTP takes action after event is happened but you will have Alert/Incident Triggered for the same.

Thanks
