P-A-S-WEBSHELLP.A.S. webshell

The P.A.S. webshell was developed by an ukrainian student, Jaroslav Volodimirovich Panchenko, who used the nick-name Profexer. It was developed in PHP and features a characteristic password-based encryption. This tool was available through a form on his website, where a user had to provide a password to receive a custom webshell. The form suggested a donation to the developer. It was commonly used, including during a WORDPRESS website attack.
