Punycode Exploit Puts One Billion Chrome & Firefox Users at Catastrophic Risk for Undetectable Phishing Attacks / Epic Privacy Browser Users are Safe

Epic users, you’re all safe :-D!

The Punycode exploit uses the way unicode is handled by the address bar of some browsers to appear to be a website it isn’t. You can test your browser by pasting this url in its address bar:

If the address bar says Apple.com as it does in Chrome and in Firefox, then you’re vulnerable. Google and Mozilla have known about this bug since late January but yet to rectify it for the billion or so Firefox and Chrome users. It’s a relatively simple issue to fix so it’s mystifying why Mozilla and Google would delay or refrain from protecting their users from potentially devastating, undetectable attacks that could steal their banking and other login credentials.

Here’s an example of the exploit.

Epic Privacy Browser is Safe on the left.  Chrome on the right is vulnerable.
