Tor Exit Nodes: How Attackers Exploit Them and How to Defend

This briefing explains what Tor exit nodes are, how they function within the Tor network, and how attackers commonly leverage them across stages of an intrusion (C2, exfiltration, scanning, credential stuffing). It maps these abuses to MITRE ATT&CK techniques and outlines defensive options—blocking, monitoring, and threat-intel enrichment—while cautioning about false positives and ethical considerations; no specific incident or IOCs are reported.
