On December 11, 2023 WPScan published Marc Montpas’ research on the stored XSS vulnerability in the popular Popup Builder plugin (200,000+ active installation) that was fixed in version 4.2.3.
A couple of days later, on December 13th, the Balada Injector campaign started infecting websites with older versions of the Popup Builder. The attack used a freshly registered (December 13) domain specialcraftbox[.]com. At the current time of writing PublicWWW detects the injection on over 6,200 sites.
