OpenCanary is a low-interaction honeypot designed to detect intruders on a network. An attacker attempting to use an OpenCanary node as an HTTP proxy is a strong indicator of reconnaissance or lateral movement, as they are attempting to route their traffic through the honeypot. This activity is logged by OpenCanary and can be detected with appropriate monitoring. The default configuration of OpenCanary includes an HTTPPROXY service that listens for proxy requests. Defenders should monitor OpenCanary logs for event ID 7001, which indicates an attempted HTTP proxy login.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains initial access to a network (e.g., through phishing or exploiting a vulnerability).\u003c/li\u003e\n\u003cli\u003eAttacker performs network reconnaissance to identify potential targets, including the OpenCanary node.\u003c/li\u003e\n\u003cli\u003eAttacker attempts to configure their system or tools to use the OpenCanary node as an HTTP proxy.\u003c/li\u003e\n\u003cli\u003eThe attacker sends HTTP requests through the configured proxy, attempting to reach other systems on the network.\u003c/li\u003e\n\u003cli\u003eOpenCanary logs the attempted proxy connection with event ID 7001.\u003c/li\u003e\n\u003cli\u003eThe defender detects the suspicious HTTP proxy attempt in the OpenCanary logs.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eA successful HTTP proxy attempt indicates that an attacker is actively exploring the network and attempting to move laterally.
