The gibberish hack automatically creates many pages with nonsensical sentences filled with keywords on the target site. Hackers do this so the hacked pages show up in Google Search.
The Japanese keywords hack typically creates new pages with Japanese text on the target site in randomly generated directory names. These pages are monetized using affiliate links to stores selling fake brand merchandise and then shown in Google search.
The cloaked keywords and link hack automatically creates many pages with non-sensical sentence, links, and images. These pages sometimes contain basic template elements from the original site, so at first glance, the pages might look like normal parts of the target site until you read the content.
Google recommends to stay up-to-date on releases and announcements from your Content Management System (CMS) providers and software/hardware vendors.
