browsers extensions Alert

L4 Transporter

Hello dear community, 

 

I would like to see more rules which are containing everything about browser extensions. Like in chrome, "browser extension was created".

 

I know to manage chrome via GPO, but there are not always Active Directories and I would like to get an alert, when a new extension is installed and also used (when it was already installed). 

 

I'm not sure, if malware extensions are blocked, because of that it would be nice to get more visibility on this attack vector.

What do you say to my idea?

Hi @RFeyertag ,

 

As of now, Cortex XDR does not work on detection and prevention of browser extensions. However, if any process activity or exploitation technique happens on the browser itself leveraging the extension, the browser activity should be blocked in that causality events.

Neel

Hi,
Do you have any ideas or a developed approach to monitoring browsers or monitoring installed extensions?

Maybe you have some XQL queries you can share or BIOC rules?
