Additional Security Enhancement

In addition to resolving the vulnerabilities listed above, the latest builds of Apex One and Apex One as a Service also have included some security enhancements to the agents' self-protection mechanisms to protect against malicious batch scripts intending to disrupt the operations of the security agents.


Mitigating Factors

Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.

However, even though an exploit may require several specific conditions to be met, Trend Micro strongly encourages customers to update to the latest builds as soon as possible.
