If you're cruising through the amazing universe of open-source projects, you might stumble upon a little gem called King Phisher—the ultimate Phishing Campaign Toolkit. This bad boy, although no longer maintained, packs a punch with its stellar features designed to ramp up your organization's security awareness by simulating real-world phishing attacks. Now, isn't that nifty? King Phisher ain't your run-of-the-mill phishing tool; it's built to be flexible and user-friendly. Whether you're just dipping your toes into awareness training or diving deep with intricate campaigns to harvest credentials (all legally, of course, with explicit permission!), King Phisher's architecture has got you covered. Multiple campaigns, email with embedded images, optional two-factor authentication, and even SMS alerts—you name it, King Phisher has it. Ever thought about geo-locating your phishing visitors? Or perhaps cloning web pages for that legit feel? King Phisher has these features out of the box. The built-in Sender Policy Framework (SPF) checks and the ability to send emails with calendar invites add that extra layer of sophistication. And hold on—the cool stuff doesn’t stop there. King Phisher allows both the client and the server to be extended with plugins. A small set of plugins come packed, but if you're feeling adventurous, you can explore or contribute to the Plugins repository. Flexibility at its finest, huh? For those who love diving into docs, King Phisher comes equipped with detailed user documentation and developer-focused guides. The project's wiki is the go-to spot to get started with your first campaigns, while developers can geek out over the in-depth technical documentation generated with Sphinx and hosted on ReadTheDocs. Now, if you plan on sprucing up your campaigns, King Phisher’s got some neat template files for both messages and server pages. Contributing to these templates? Easy-peasy—just submit a pull request to the Templates repository. Working with King Phisher means you'll need to get comfy with some key template variables. From target email addresses to unique tracking identifiers, these variables make sure your campaigns hit home with pinpoint accuracy. The uid, especially, is essential for tracking—don't miss out on including it in your links. King Phisher is wrapped up under the BSD 3-clause license, encouraging collaboration and sharing within legal bounds. Special thanks go out to the QA/Beta Testing team and the rockstar King Phisher Development Team, who’ve put in the hard yards to make this project what it is. Ready to up your phishing game?
