The trick used here is to start a ping command (from VBA macros) that will take several minutes to execute: cmd.exe /C ping 188.8.131.52 -n 250 > nul
This command does 250 pings to Google DNS 184.108.40.206. It will take around 4 minutes and 10 seconds to execute. And after that, the VBA code downloads and executes malware.
