Chrome and Firefox Phishing Attack Uses Domains Identical to Known Safe SitesApril 15, 2017 – 7:05 PM
There is a phishing attack that is receiving much attention today in the security community.
As a reminder: A phishing attack is when an attacker sends you an email that contains a link to a malicious website. You click on the link because it appears to be trusted. Merely visiting the website may infect your computer or you may be tricked into signing into the malicious site with credentials from a site you trust. The attacker then has access to your username, password and any other sensitive information they can trick you into providing.
This variant of a phishing attack uses unicode to register domains that look identical to real domains. These fake domains can be used in phishing attacks to fool users into signing into a fake website, thereby handing over their login credentials to an attacker.
This affects the current version of Chrome browser, which is version 57.0.2987 and the current version of Firefox, which is version 52.0.2. This does not affect Internet Explorer or Safari browsers.
We created our own example to demonstrate how an attacker can register their own domain that looks identical to another company’s domain in the browser. We decided to imitate a healthcare site called ‘epic.com’ by registering our own fake site. You can visit our demo site here in Chrome or Firefox. For comparison you can click here to visit the real epic.com.
