[QUOTE="Andy Ful, post: 972718, member: 32260"] Yes, you are right. My downloads via FTP in PowerShell were blocked, but not by the lack of native support. They were blocked by Constrained Language Mode in PowerShell. I corrected my previous posts. Still, it is interesting how popular are the attacks in the wild performed fully via FTP.:unsure: I can imagine that the malware can upload the data to the malicious FTP server and download from it the file with instructions. But such attacks have to transfer many files, so they are probably not popular. Edit.
