Reviewing Kippo Logs
When I first started running Kippo almost a year ago I had no difficulty getting motivated to log into the honeypot, check for new connections and generally get a feel for what my
victims visitors have been up to. As time went by, sessions started to follow familiar patterns and some days would get no hits. Slowly I’d check the logs less frequently, and when I did I’d get an ever increasing backlog to review, decreasing my motivation further.
Recently I got annoyed with myself, my system was ticking along in the background but I was gaining no benefit from it. So in a moment of madness I dusted off my bash and built a quick script to provide a daily review of activity on my system. Essentially this does two things, lists session interaction and files downloaded within the last 24hours.
I’ve had the routine running daily for around a week; for days there was minmal activity on my system, either no logins at all, or logins with immediate disconnects. Today was different, and marked the first success of the script. Delivered to my morning inbox, along with the rest of my regular quick tasks and RSS feed as an interesting session. Malicious user connects, downloads a scanner (archive contents looks like gosh), an irc bot (looks like EnergyMech derivative); and when attempts to run toolkit fail, downloads and runs three (yes, three, paranoia is strong with this one) log cleaners.
