# tor\_connection\_external\_internal **Explanation** This event is triggered by Netography’s Fusion Portal when it detects traffic originating from a TOR network exit node communicating with monitored hosts. Traffic from the TOR network is not inherently malicious; however, attackers will commonly use the TOR network to hide the origin of other attacks. These attacks might include: password brute forcing, host or vulnerability discovery (scanning), or data exfiltration. **What to Look For** Scanning activity from the Internet is very common, and this event is not necessarily concerning or even malicious. Some things to investigate include: traffic to hosts not expected to be reachable from the Internet, lots of requests to a single host, a large volume of data leaving a single host. **Related MITRE ATT\&CK Categories** [Command and Control: Proxy, Technique T1090 - Enterprise](https://attack.mitre.org/techniques/T1090) --- # 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.
