McAfee: 65 Million Malware Samples — And That’s Just the Tip of the Iceberg

I was fascinated by this article that came across my newsfeed earlier this week. In it, McAfee says that they have hit 65 million malware samples in the 2nd quarter of 2011.

I have heard similar stories in my frequent conversations with other AV vendors this year. It seems, that the malware cat, truly is out of the bag. I don’t know about you, but it seems like someone forgot to warn the crimeware world about opening Pandora’s box.

One of the things that I think is still interesting about the number of signatures that AV vendors are creating are that they are still hitting only a small portion of the overall mountain of malware.

For example, many of the AV vendors do not cover very many of the current PHP and ASP malware that is making the rounds. If you follow me on twitter (@LBHuston), then you have likely seen some of the examples I have been posting for the last year or so about this missing coverage.

In addition, in many of the public talks I have been giving, many folks have had wide discussions about whether or not AV vendors should be including such coverage. Many people continue to be amazed at just how difficult the role of the AV vendor has become. With so much malware available, and so many kits on the market, the problem just continues to get worse and worse.

Additionally, many vendors are still dealing with even the most simple evasion techniques. With all of that in mind, the role and work of AV vendors is truly becoming a nightmare.

Hopefully, this report will give some folks insight into the challenges that the AV teams are facing. AV is a good baseline solution. However, it is critical that administrators and network security teams understand the limitations of this solution.

Simple heuristics will not do in a malware world where code entropy, encoding and new evasion techniques are running wild. AV vendors and the rest of us must begin to embrace the idea of anomaly detection. We must find new ways to identify code, and its behavior mechanisms that are potentially damaging.

In our case, we have tried to take such steps forward in our HoneyPoint line of products and our WASP product in particular. While not a panacea, it is a new way of looking at the problem and it brings new visibility and new capability to security teams.

I enjoyed this article and I really hope it creates a new level of discussion around the complexities of malware and the controls that are required by most organizations to manage malware threats.

If you still believe that simple AV or no malware controls at all are any kind of a solution, quite frankly, you’re simply doing it wrong. As always, thanks for reading and stay safe out there.
