html.spam-seo.hiddendiv.001

Blackhat SEO, or spam-seo, is a malicious technique used to manipulate the search engine results in order to benefit a website in terms of relevance.
The payload is HTML based, thus intended for client-side use and the payload is executed after the infected page is loaded directly in the browser.
One of the techniques for placing a spam seo insertion in a site code is inserting a hidden div marker in a theme file, like header or footer, which will be loaded every time a page is rendered. It can also rely on a javascript code to change the <div> attributes to hidden as an attempt to hide the payload from scanners that will look for explicit hidden markers only
