# 8888\_scan\_internal\_external **Explanation** This NDM is designed to detect scanning for port 8888 that is exiting the customer's network. Port 8888 is used as an alternative HTTP port by many software products. It is also used by ManageEngine's AdSelfService Plus. Outbound scanning for port 8888 may be indicative of an infection and an attacker using a compromised machine on the customer network to pivot further outside of the network. **What to Look For** Scans launched from your network may be an indication that your network is compromised. Investigate hosts that are the source of this sort of activity in order to make sure that it is authorized and expected, and the hosts have not been compromised. This event could false positive in a situation where Netography has not been configured with the appropriate internal network IP address ranges. **Related MITRE ATT\&CK Categories** [Discovery: Network Service Discovery, Technique T1046 - Enterprise](https://attack.mitre.org/techniques/T1046) [Reconnaissance: Active Scanning, Technique T1595 - Enterprise](https://attack.mitre.org/techniques/T1595) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
