The Adversary Tactics and Techniques Detection pattern is a new pattern for the new hypersensitive mode feature, and this pattern does not support update with Deep Security Agent version lower than version 20.0.1.3180. The security out-of-date shown on console does not impact the capability of the Anti-Malware security feature.

To fix this issue, 
Upgrade the agent to version DSA 20 LTS Update 2024-02-29 (20.0.1.3180) or higher.
