LinkJack by rox-11

LinkJack is an automated security extension designed for bug bounty hunters, security researchers, and web developers to discover Broken Link Hijacking BLH vulnerabilities effortlessly as they browse.
When websites link to deleted, unclaimed, or broken social media accounts such as Twitter GitHub and more attackers can claim those handles to impersonate brands or execute phishing attacks. LinkJack runs silently in the background to spot these vulnerable links before anyone else does.
