Attack surface reduction

[ChrisQ]

I've followed KB93741 Knowledge Center - REGISTERED - Attack Surface Reduction content (mcafee.com)

and am testing it with an xlsm file to see if I can trigger the ASROFFMACRO rule. 

So far I have been unable to get any detections, even though I have a file with macros in it.

I've followed all the instructions, cleared the cache and done a right-click scan on the file but it's not detecting it. Although the article does not mention it, I assume these expert rules can be applied via ePO, so attached is a screen shot of my settings, currently set to report only.

Has anyone else managed to get these ASR rules to work?

Further testing has shown that, although the article says "McAfee recommends that you change the Actions settings when you first enable ASR content so that you can see its impact." setting the action to report only does not work, but once you set it to block, the rule works.

This is not very helpful, and the article needs to be changed to reflect this.

@ChrisQ Sorry to comment on an old post, but was this the case? I have been testing a lot of my expert rules recently in mcafee and then sometimes work, sometimes don't but work all the time when in blocking mode. Not great when I want to push a company wide change
