This is 1/2 of the work done... lot's of cool stuff!
I've re-written a decent amount of the framework to support dynamic config file updates, revamped the ARP Spoofing 'engine' and changed the way MITMf integrates Responder and Netcreds. - Net-creds is now started by default and no longer a plugin.. It's all about getting those creds after all. - Integrated the Subterfuge Framework's ARPWatch script, it will enable itself when spoofing the whole subnet (also squashed bugs in the original ARP spoofing code) - The spoof plugin now supports specifying a range of targets (e.g. --target 10.10.10.1-15) and multiple targets (e.g. --target 10.10.10.1,10.10.10.2) - An SMB Server is now started by default, MITMf now uses Impacket's SMBserver as supposed to the one built into Responder, mainly for 2 reasons: 1) Impacket is moving towards SMB2 support and is actively developed 2) Impacket's SMB server is fully functional as supposed to Responder's (will be adding a section for it in the config file) 3) Responder's SMB server was unrealiable when used through MITMf (After spending a day trying to figure out why, I just gave up and yanked it out) - Responder's code has been broken down into single importable classes (way easier to manage and read, ugh!) - Started adding dynamic config support to Responder's code and changed the logging messages to be a bit more readable. - POST data captured through the proxy will now only be logged and printed to STDOUT when it's decodable to UTF-8 (this prevents logging encrypted data which is no use) - Responder and the Beefapi script are no longer submodules (they seem to be a pain to package, so i removed them to help a brother out) - Some plugins are missing because I'm currently re-writing them, will be added later - Main plugin class now inharates from the ConfigWatcher class, this way plugins will support dynamic configs natively! \o/
