Creating illegal files can also exceed 360 by using short names. Upload cmd.exe 1, its short name is CMD ~ 1. EXE, which can be used as EXE.

The target machine MS has file monitoring and cannot upload scripts or executable files such as asp, asa, exe, and com. After obtaining the shell, the semicolon vulnerability encountered a problem when uploading cmd. Later, I broke through with a short name. After 3389 privilege escalation, I found that macark was used to set file rules to prevent Trojans and executable programs from being uploaded.

You can also directly upload the file named cmd. cao, which can be executed if no virus is killed.
