Hi, can I ask you where I can find the content update version with the release date?

By example: the Cortex XDR agent content version 172-54504, when was released? 

 

Thanks

Hi,

 

For this Added Medium Analytics BIOCs:

  • Possible Microsoft module side-loading into Microsoft process (d0a0b07d-3b72-41fc-b5aa-627cf23b4414) - added a new Medium alert

Is it possible to alert this kind of attack?

Hi,


the Info that something changed for the better is nice, but it'd be even better if there is a possibility to review the changes made.
To this day I think there isn't a possibility to view Analytics BIOC Rules.
The fact that Cortex XDR isn't a "black box" like other XDR/EDR products, that it's possible to view and alter standard BIOC Rules was the deciding factor for us to take the product into our MSSP program.

 

Best regards

Hi @vcotton ,
Could you please provide information on the changes that came with content 700-18331 released on 22 September 2022?

A customer of mine is having issues with their SQL servers since the content version was installed.

Thanks,

Tim

Hi @vcotton ,

 

shouldn't this page be only available to people who login ? as not to give too much information to TAs ? Just thinking. 

This page is for the moment available to anybody.

 

Regards

Frank
