Attacks overwrite the process environment block to replace the logged command line after a process is created suspended, so Windows, Sysmon and Defender XDR record a spoofed command line while the real command runs; demonstrations show built-in tools, PowerShell cmdlets and encoded commands can be hidden. Enterprise EDRs catch roughly 50% of tests, a student rewrite in C bypasses EDRs, and Microsoft declines a servicing fix so this affects Windows, Sysmon and Defender XDR visibility.
