ConfluencePot is a simple honeypot for the Atlassian Confluence unauthenticated and remote OGNL injection vulnerability (CVE-2022-26134).
You can find the official advisory by Atlassian to this vulerability here. For details about the inner workings and exploits in the wild you should refer to the reports by Rapid7 and Cloudflare. Affected but not yet patched systems should be deemed compromised until further investigation.
ConfluencePot is written in Golang and implements its own HTTPS server to minimize the overall attack surface. To make it appear like a legit Confluence instance it returns a bare-bones version of a Confluence landing page. Log output is written to stdout and a log file on disk. ConfluencePot DOES NOT allow attackers to execute commands/code on your machine, it only logs requests and returns a bogus response.
You need a recent version of Golang to run/build confluencePot and the appropriate privileges to bind to port 443. We recommend to execute it in a tmux session for easier handling. To run ConfluencePot you either need to create a self-signed TLS certificate with openssl or request one from e.g. Let’s Encrypt.

DNS cache is a temporary database your OS and browser build as you browse. Each time you visit a website, the domain-to-IP mapping is saved locally, cutting out the round trip to a remote DNS server on repeat visits. Stale entries are the most common reason to flush the DNS cache: a server moves to a new IP, but your OS or browser still routes to the old address. This guide covers how to clear the DNS cache on Windows, Linux, and macOS, and how to flush the separate cache stored inside Chrome and Firefox. Flush DNS Cache on Windows The command is the same on Windows 10, Windows 11, and earlier supported releases. Open Command Prompt with administrator privileges.
