As a noob who had spent many hours on Arctic, specifically on getting priv esc and not being able to get it despite following guides I though I would share this short post in case anyone else runs into this issue who may also be fairly inexperienced.
As far as the priv esc I was referring to this guide by using powershell to pull the pre-compiled exploit MS10-059 Chimichurri.exe down to the target machine. I would follow this line for line and get no response from my SimpleHTTPServer when executing the wget.ps1 file. After hours of reading into powershell and other posts on here I simply changed all double quotes for $file and $url values to single quotes and boom it worked perfectly. I was then able to execute the exploit and get an elevated shell. Hope this helps someone!
