To mitigate the risks posed by these vulnerabilities, Trend Micro advises organizations to take immediate action.
First and foremost, ensure that the latest patches and updates are applied promptly to affected Apex One products, as the vulnerabilities require system updates to be addressed effectively.
Since exploiting these issues typically requires an attacker to have local access to the target machine, organizations should also restrict physical and remote access to critical systems.
Reviewing and updating perimeter security measures, such as access controls and remote access policies, is crucial to minimizing exposure.
Adopting robust cybersecurity best practices, including privileged access management, network segmentation, and proactive monitoring, can provide an additional layer of defense against similar exploitation attempts in the future.
