Faking a Virtual Machine

One of the more popular trends in the recent years is the move of malicious code analysts towards virtual machines to test and reverse-engineer malicious code. And surprisingly the virus/worm writers have been adding mechanisms to their code to detect such environments.

I came across this particular piece of software called Themida which does exactly that. Lenny Zeltser from SANS reports about this on SANS. Whats interesting is that this kind of detection is now part of commercial packers around the world.
The question I have is this, how long will it take for someone to come up with a VMWare/Virtual Machine simulator/faker which I can run on my perfect non-virtual desktop/laptop/server and make malwares believe its running inside a Virtual machine ?

If that can kill even a small percent of fresh 0-day worms/viruses, it would be worth the effort. Wouldn't it ?

Creating your first chrome app on a Chromebook

Image
Doing development on Chromebook usually means developing online. There are a lot of sites around for that. But with the APIs getting more mature, its just a matter of time before someone builds a kick-ass IDE which runs natively on Chromebooks without network connectivity. One such tool which I've been exploring for a last few weeks is from Google and called " Chrome Dev Editor " If you have never built and run a chrome app or extension, I'll show you how to do this in 3 easy steps.     Step 1 Launch the app and click on the "+" button to add a new project. Pick a project name and select "JavaScript Chrome App" in the drop down menu.       Step 2 Notice how it automatically adds the minimum code required for it to run. This will be the template you are going to work with. You are almost done, but lets review the files in there to understand why they are there.   manifest.json - This is the most important file. Modify the app name, version number

Brewers CAP Theorem on distributed systems

Image
Large distributed systems run into a problem which smaller systems don’t usually have to worry about. “ Brewers CAP Theorem ” [ Ref 1 ] [ Ref 2 ] [ Ref 3 ]  defines this problem in a very simple way. It states, that though its desirable to have Consistency, High-Availability and Partition-tolerance in every system, unfortunately no system can achieve all three at the same time . C onsistent : A fully Consistent system is one where the system can guarantee that once you store a state (lets say “x=y”) in the system, it will report the same state in every subsequent operation until the state is explicitly changed by something outside the system. [ Example 1 ] A single MySQL database instance is automatically fully consistent since there is only one node keeping the state. [ Example 2 ] If two MySQL servers are involved, and if the system is designed in such a way that all keys starting “a” to “m” is kept on server 1, and keys “n” to “z” are kept on server

The pain of Load balancing applications

Introduction Loadbalancing may mean many different things to different people but its all about distributing load. For me its an architecture of how some network services can be scaled by adding multiple servers performing the same tasks. If you had a popular website with static content, and if your server couldn't keep up with the request, all you had to do was setup multiple web servers and use round-robin DNS entries to divide the load into multiple servers. For dynamic web applications like search engines this plays a significant role because the number of users per node can support is much lower. Over time, as applications grew more complex and as web companies found customers outside US they found out the hardware that the only way to optimize network performance was by going local. Loadbalancing POP (points of presence) around the world provide a snappy user experience which has been important and drawing more customers. While, static content on web servers can easily be rep
