Once you have unpacked this sample and you load it in IDA you will see they dynamically resolve their APIs, you can quickly fix this by loading the PE in a debugger, adding a breakpoint after the first function, run until breakpoint. Then use scyla to dump and fix imports!

We use the Ollydbg CiM build because I am on holidays and don't have my full VM tools but you can use x64dbg the commands are the same : )
