WP-VCD is a malware that  creates backdoors in your website by adding other hidden WordPress admin users or a backdoor account with the name 100010010 .This exploit then allows the attackers to have full access to your site  and maintain a persistent foothold on these infected sites.

A thorough research by Wordfence found out that the rates of VCD attacks have been on the rise since August 2019.

WP-VCD has been around since at least February 2017, becoming more and more prevalent over the course of that year.

Nowadays, Wordfence says WP-VCD is today’s top hacking group on the WordPress landscape.

The attackers sole intention is monetization which comes from two main sources:

  • viral marketing activity intended to manipulate search engine results
  • malvertising code which creates potentially dangerous redirects and pop-up ads for users on a compromised site.
 

How it spreads

  •  Using outdated WordPress plugins & themes for your site. 
  • Downloading and installing free pirated premium WordPress themes
