In this case, the hackers serve the fake DDoS protection pages by adding a line of JavaScript code in the hacked WordPress sites. “Since these types of browser checks are so common on the web, many users would not hesitate to click this prompt to access the website they are trying to visit,” the Sucuri security researcher wrote. , Ben Martin.(Opens in a new window) in a blog post.

Specifically, fake DDoS protection pages will download a file called “security_install.iso” onto the victim’s computer. The WordPress site will then show an additional popup asking the user to install the ISO file to get a verification code.
