In the past, there was some interest in the setting up of honeypots on BSD operating systems with tools like honeyd. Honeypots attempt to capture malicious code, network worms and attackers by emulating vulnerable services using a variety of methods. An opportunity came up for me to try to capture some malicious code using a simple setup with FreeBSD and jails. The setup was simple and easy to replicate as a way to perform security research on current attacks across the Internet and correlate with other threat sources for analysis.
