Publishing copyrighted material on GitHub for phishing
<p>I want to publish some demo code on github that deals with a new type of phishing attack. However, I've used a Google-branded sign-in page for the demo. Will this be a problem with copyright or any legal issues?</p>

<p>Obviously, Google owns their copyrights. I can't say they will for sure sue you for it, but it's their property and they can make that decision if they choose to. </p>
