Hello World!
Ok. So here's the rub, even with the code provided by JBNZ and Sebkinne, it absolutely does not work on any browser on any of my 10.9, 10.10, and 10.11 Macs. You have to manually type the IP and port, and only sometimes will that actually work. However, on a Windows 10 computer, that I never use, it ran on it's first try- opened a browser, redirected to the Captive Portal, and recorded every failed attempt in a nice log file!
Perhaps it helps that there's a nice EXE for Windows to use, but what about Apple's architecture? What's handling that? Final question- how is this practical? The Bash Bunny is meant to be inserted into the target computer that the "mark" will be using. So, how do we get it back? Please take mercy on my first post and I promise to read every response. Thank you all in advance :-)
