Hi there, i'm new to this forum and I have a question... I tried to write a script for my Rubber Ducky, which should run PasswordFox and Chromepass on the victim's machine, but if I try to run run PasswordFox with PasswordFox.exe /stext passwords.txt but ever when I do this, PasswordFox only opens the GUI and creates no .txt?!?! Could anyone help me? Greetings, Crococksmiltsch
