Global CMS Exploitation Campaign: Protect Your Website Now
In July 2026, the Australian Cyber Security Centre (ACSC) issued an alert regarding a global exploitation campaign targeting vulnerabilities in content management systems (CMS) and associated plugins. Threat actors are actively scanning websites to deploy webshells, leveraging flaws in platforms such as WordPress, Craft CMS, MaxSite CMS, MetInfo CMS, and Joomla JCE. This campaign has significantly impacted small to medium-sized Australian businesses, leading to service disruptions, credential theft, malware deployment, and potential lateral movement within networks. The ACSC highlighted that the campaign might be supported by artificial intelligence, enabling threat actors to accelerate attacks and scale the exploitation of emerging vulnerabilities. Website administrators are urged to apply the latest security updates, remove unused components, enable automatic updates where possible, and implement additional security measures to mitigate the risk of compromise.
