Details:

On July 18, 2023, Microsoft will be retiring a subset of signatures found in the "NetworkSignaturesInspected" action type of Advanced Hunting. With the recent integration of Zeek providing advanced protocol parsing capabilities, which result in better visibility into full network sessions compared to the raw packet bytes found in the "NetworkSignaturesInspected" action type of Advanced Hunting today, the effort to consolidate will provide a better overall experience for our customers by reducing the signatures that serve similar functions without the added benefits provided by the new Zeek alternative.
[When this will happen:]
