Web cache deception attacks are still a major cybersecurity issue for many popular websites. According to ZDNet, 25 of Alexa Top 5,000 websites are still impacted by these types of attacks. That number may seem small—until you understand the critical damage they can cause.

Definition

A web cache deception attack is a strategy used by hackers to steal personal login credentials. It’s when a boobytrapped website link essentially snaps a picture of a page that contains user’s personal information. It caches it and stores it inside a front-facing content delivery network (CDN). These pages might be personal dashboard pages, settings pages or financial details pages. The attacker would then be able to use the cached page to retrieve sensitive data.

For those top 25 websites that receive so much traffic, that’s a lot of individual’s data being stolen. Cybersecurity companies know that employees’ online behavior can eventually make your business vulnerable if you are not taking precautions to stay secure.

Defense

It’s especially important to make sure that your own website stays secure so that you don’t lose the customer trust. Expert cybersecurity companies and researchers have found that one of the best ways to protect your website is to make sure that it doesn’t treat nonexistent paths as equivalent to valid parent paths.

For example, attackers will use URLs like /myaccount/home/blabber.jpg to lead site visitors to a deceptive page. The website may treat the fake url the same as the /myaccount parent tag. You want to make sure that the fake requests lead to 404 error pages rather than cached personal data.
