Cyberwarfare and Cybercrime – more links turn out in study

Whenever you look at cybercrime/eCrime, the question always pops up – what is the link between this highly sofisticated economy and aggregation of technologies, with government affairs or cyberwarfare. The answer would usually be “it depends”… Actually depending on who you ask, and what level of involvement they have with studying cyberwarfare as well as cybercrime.

When I spoke at DefCon last month it was a great opportunity to catch up with some of the leaders in the study of cyberwarfare and cybercrime, and as always the discussions were really eye opening as we all had a chance to “compare notes” and fill in some pieces of the puzzle where crime turns into warfare and vice-versa. Following DefCon and BlackHat with almost perfect timing, the US-CCU (United States Cyber Consequence Unit) has published a research which again alludes to the links between cyberwarfare and the involvement of cybercrime. The study talks about the fact that companies and individuals may be targeted as part of a campaign, and may also be part of the attack when looking at things from the other side.

What’s important to remember is that some of the research relied on studying the last Russia-Georgia conflict in which attacks were also launched using commercial botnets – a fact that may skew the stats a bit and throw innocent individuals and companies into the same pool as premeditated attackers, just because their systems were infected and part of the botnet.

Just a quick word of advice – always remember to look at the whole picture when reading such studies, as even the most professional research may focus on specific aspects of the subject in matter and might skew the conclusions (as implicit or explicit as they may be) as a result.

Botnet communications moving to Web2.0

A great find by Jose Nazario shows how botnets have moved on from relying on old-school communication schemes (usually IRC or direct HTTP connections) to utilizing the tools that Web2.0 provides.

I have been naming this development since it started being discussed in the back-channels, and predicted that these would be the next generation communication methods as they provide not only another layer of separation (anonymity) between the botnet manager and the controlled bots/trojans, but also a layer of scalability to the control scheme.

You can check out the last time I discussed this on my DefCon presentation slides which should be uploaded to the DefCon site soon. In the meantime here is an older presentation (at least 10 months old) where the same subject is being demonstrated (slides 31-32):
Behind the Scenes of E Crime July09

Basically, the Twitter messages are encrypted codes being sent between the command and control and the controlled bots, which is very close to the “homework” I mentioned at the end of my DefCon talk – encouraging researchers to look for “garbage” data on blogs and Web2.0 services which are actually encrypted data being passed over a public medium.

I guess that that’s one more issue to deal with when trying to deal with the growing threat of eCrime and cyberwarfare.
