No single technology can do or handle every situation; the same holds true with honeypot sensors which is why I’m always interested in finding new systems to add to my environment. I’d had Amun on my list of potentials for a while, but after reading a short blog post by Miguel Cabrerizo that suggested install and setup was relatively quick and painless, it got moved up the to-do list.
As suggested the install was quick and easy, with no real problems. Since being installed the system has done what it says on the tin, emulating vulnerabilities and logging interaction with attacking sources. The sensor has been active for around 5 days and has collected 14 unique malware samples to date. Whilst not immediately being indicative of any comparison, three of these samples have not also been ensnared by Nepenthes or Dionaea sensors running within the same IP space.
The Amun log directory shows some interesting information, with logging being split between several different files. From initial results there is some interesting information collected by the system. One aspect of the logging that I’m unsure if I like is that Amun rotates it’s log files on a daily basis, so far this is resulting in my log directory getting cluttered with rotated files. For the curious available log files are:
Going forward there are a number of installation and configurations options available from Amun that I intend to experiment with; high up this list is the ability to log to a MySQL database, I’m hoping that this will provide both a convenient and powerful way to search and analyse the information collected by the sensor. In the meantime Miguel has extended one of InfoSanity’s submission_stats to gather similar statistics from Amun sensors, Miguel’s work is available here.
