'Fleisnam' malware was detected (Agentless) - false alarm?
Hi experts,
I have started to see this alert some time ago on a VM sitting in Azure. Tried to troubleshoot it, made some research and turned out this is triggered by Defender reporting it's own log files as malicious. At least that's what I've found on several blogs.
It will identify a "log" file looks like every time I run defender full scan. An example of the file and location is below:
Last few days, few more devices started to report the same... and I start to be a bit "nervous" about it. Is it a real malware? Is it really a defender bug?
Anyone experiencing the same issue?
Thank you.

sumo83 Hi, I had a similar issue some time ago, when I was in doubt, even if it was a false positive, I sent a request to verify the false positive: you can send the file for analysis to Microsoft via their security portal if you are concerned and want an official confirmation.
- submitted to MS. How did you deal with it then? Have you just ignored and closed any further alarms?
sumo83 Once I received the feedback confirming the false positive I closed the case
