I want to create a test environment to test malware tools and AV tools with malware. What is the best network setting in VirtualBox to test malware without infecting your own network ?
Actually default settings of NAT is fine already because it isolates and create virtual network system that makes it a very low chance to make your host system infected at any case especially worms.
I have also red that for example the CryptoLocker virus is smart to "see" if it is running in a virtual environment. How do you test your av against the cryptolocker for example?
