Beyond Clickbait: Open Redirection Vulnerabilities

Remember those adorable cat video links a friend sent you last week? Turns out, they might have been a cunning cybercriminal's attempt to steal your login credentials in 2023! Open redirection vulnerabilities are lurking in the shadows of the web, just waiting to send you down a deceptive path.

What's the deal?

Imagine a website uses your search term to redirect you to relevant results. But what if a hacker could manipulate that search term to send you to a fake login page disguised as your bank or social media account? Open redirections allow exactly that.

Recent Purr-petrators:

• August 2023: Security researchers identified a rise in "cat-phishing" scams using open redirects. Hackers hijacked trusted websites to redirect users to malicious, yet seemingly harmless, cat video links. Click. Login. Hacked!
• Multiple vulnerabilities throughout 2022 and 2023: Open redirect vulnerabilities were found in popular software like Apache Tomcat (CVE-2023-41080) and Tornado (CVE-2023-28370). These highlight the ongoing threat across various platforms.

Stay Paw-sitive: How to Protect Yourself

• Beware of shortened URLs: They can mask a malicious destination.
• Hover over the link: See the actual URL before you click. Is it your grandma's cat collection or something fishy?
• Bookmark trusted sites: Avoid the click-and-pray approach.
• Use a password manager: Don't fall for copy-and-paste login traps.
• Update your software: Patches often fix vulnerabilities.

Website Owners: Don't Be a Scratching Post for Hackers!

• Validate user input: Don't trust everything a user types blindly.
• Whitelist allowed URLs: Only redirect to pre-approved destinations.
• Consider alternatives: Maybe user-controlled redirects aren't perfect for your site.

Let's work together to keep the web a safe space for all, free from both malware and misleading moggies!
