As for trends in vulnerability exploitation, we are seeing increasing rates of attacks targeting older operating system versions. This is mainly driven by two factors: users not installing updates promptly, and the ongoing rollout of new OS versions that include improved protections against the exploitation of vulnerabilities in certain subsystems.
