[QUOTE="Andy Ful, post: 971528, member: 32260"] After some thinking and experimenting, I found easily several other files that are not automatically scanned by Defender. It is easy to predict which files will be ignored by the Defender when opening a folder. After changing their file extension to EXE, Defender can immediately detect them just like in the case of renamed DumpStack.log. Edit. When the malicious file is downloaded via Edge (SmartScreen disabled) with the file name DumpStack.log, it is detected by Defender (download fails). If it is downloaded by Firefox (and not blocked by Firefox) then Defender allows the download. It seems that downloading the file via certutil LOLBin is similar to Firefox. Furthermore, the files like DumpStack.log are scanned by Defender when copying or opening in the notepad. [/QUOTE]
