I always wondered — *okay, but who's actually behind this?</p> <p>So I built something that answers that. It's a Chrome extension paired with a small backend that runs on your machine. When it detects something suspicious, it automatically cleans up your session and quarantines the tab — no clicking required. And instead of just saying "this is dangerous," it tries to trace the attack back to where it's really coming from.</p> <p>It's a student project. It works, but it's definitely not perfect.</p> <h2> What I need from you </h2> <ul> <li>Try to use it and tell me what breaks</li> <li>Report bugs (GitHub Issues are open)</li> <li>Tell me honestly what's confusing or missing</li> <li>Ideas for what you'd want a tool like this to do</li> </ul> <p>Everything you need is in the README — setup is one command.</p> <p>👉 <a href="https://github.com/Mayank3613/Probable-Octo-Palm-Tree" rel="noopener noreferrer">GitHub link</a></p> <p>Any feedback at all helps.
