The actual file paths look like: C:\WINDOWS\System32\Kefcbfwztlxk\ppfiimnvbwkgw.nvgĬ:\windows\syswow64\txrsryjkrhlvwvve\sgnzjys.dyw The artifacts in question looked like: C:\WINDOWS\System32\Random Folder Name\Random File Name.Random File TypeĬ:\windows\syswow64\Random Folder Name\Random File Name.Random File Type I was recently asked about a use case regarding finding Emotet malware artifacts using Live Query.
