# messaging\_zalo

**Explanation**

The messaging\_zalo NDM is a network security event designed to detect the use of messaging applications on the network, with a particular focus on the Zalo messaging platform.

**What to Look For**

To examine the results of the messaging\_zalo event, network administrators should look for traffic patterns associated with Zalo messaging. This may include an increase in traffic volume or the use of specific ports or protocols that are associated with the Zalo platform. Endpoint forensic analysis may also be necessary to identify individual users or devices that are using the Zalo messaging app on the network. Remediation may involve blocking Zalo messaging traffic or implementing stricter access controls to prevent unauthorized use of the application.
