I ran a simulation from Barkley which is their Stackhackr test tool. I used the payload where it simulates stealing personal info like credentials from active LSASS processes. Sophos Home missed the file and the behaviour components missed the simulated active process. this may need some further investigation since this looks like a serious vulnerability.
Here is the exact test file: *Malicious content Removed*
Hey, I agree with the reason on why you removed the link. I wiuld just like to clarify that the file is not in any way malicious. It is only a harmless file that SIMULATES malicious attacks such as file-less ransomware or credential theft through LSASS processes. I have tested Sophos with the file-less ransomware vector which Sophos correctly detects and blocks. Sophos did fail the credential theft scenario, and this is why I posted about it in the first place. Hope this clarifies anything.
How It Works:
