[QUOTE="Andy Ful, post: 1122613, member: 32260"] [USER=114717]@bazang[/USER], Half of your post was unnecessary. It is clear that Leo did some extended analysis for one malware sample (Unicorn), but he did nothing for the rest of the executed samples (17 samples). So, what blocked those samples? We do not know, and neither Leo do. Let's assume that those 17 samples were blocked similarly to Unicorn (although there is no evidence for that). So, Microsoft Defender detected all malware (including payloads) without behavior blocking, except one sample that was fully mitigated without behavior blocking. So, behavior blocking was not tested at all (not challenged in this presentation). In this way, Leo would be right to conclude that Microsoft Defender has decent signatures, but his statement about behavior blocking has nothing to do with the video. [B]But, a more probable scenario is that some of those samples were blocked by behavior-based detections (locally or in the cloud).[/B] [ATTACH type="full" width="251px" alt="1744536785667.png"]288097[/ATTACH] I do not agree. As you have noticed, two Microsoft Defender alerts required the user actions (restarting the device). Ignoring those alerts caused the system inoperable (which worried Leo). If Leo did restart the system, Microsoft Defender would kill all unwanted processes without problems. There is no evidence for poor heuristics and behavior blocking. Leo is not an expert on Microsoft Defender. The same is true for other solutions, except default-deny. So according to your argumentation, all non-block-by-default solutions have poor heuristics and behavior blocking. Leo did not present poor Defender showing in his videos, except for some videos with disabled Internet. Leo and I do not share your viewpoint. In his recent videos, he says the opposite. He sees the difference in such features as VPN, Password Manager, staff support, human expert analysis, etc. However, such features are common in businesses and not at home. Furthermore, Microsoft Defender is not a standalone security solution on Windows 10+. You have also Edge web browser, Windows Firewall, SmartScreen (integrated with File Explorer), Core Isolation, etc. [/QUOTE]
