WordPress sites are being targeted by a previously unknown strain of Linux malware that exploits flaws in over two dozen plugins and themes to compromise vulnerable systems.

“If sites use outdated versions of such add-ons, lacking crucial fixes, the targeted web pages are injected with malicious JavaScripts,” Russian security vendor Doctor Web said in a report published last week. “As a result, when users click on any area of an attacked page, they are redirected to other sites.”

The attacks involve weaponizing a list of known security vulnerabilities in 19 different plugins and themes that are likely installed on a WordPress site, using it to deploy an implant that can target a specific website to further expand the network.

It’s also capable of injecting JavaScript code retrieved from a remote server in order to redirect the site visitors to an arbitrary website of the attacker’s choice.

Doctor Web said it identified a second version of the backdoor, which uses a new command-and-control (C2) domain as well as an updated list of flaws spanning 11 additional plugins, taking the total to 30.

The targeted plugins and themes are below –

  • WP Live Chat Support
  • Yuzo Related Posts
  • Yellow Pencil Visual CSS Style Editor
  • Easy WP SMTP
  • WP GDPR Compliance
  • Newspaper (CVE-2016-10972)

  • WP Quick Booking Manager

  • Blog Designer
  • WordPress Ultimate FAQ (CVE-2019-17232 and CVE-2019-17233)

  • ND Shortcodes

  • Coming Soon Page and Maintenance Mode
  • Hybrid
  • Brizy
  • FV Flowplayer Video Player

  • Onetone
  • Simple Fields
  • Delucks SEO

  • Social Metrics Tracker

  • Rich Reviews

Both variants are said to include an unimplemented method for brute-forcing WordPress administrator accounts, although it’s not clear if it’s a remnant from an earlier version or a functionality that’s yet to see the light.

“If such an option is implemented in newer versions of the backdoor, cybercriminals will even be able to successfully attack some of those websites that use current plugin versions with patched vulnerabilities,” the company said.

WordPress users are recommended to keep all the components of the platform up-to-date, including third-party add-ons …….
