At Crimson Wall we recently performed an interesting malware experiment. We downloaded thousands of malware applications, ran them and documented their behaviour. The results obtained were in some cases not what we expected. The experiment and results obtained are discussed in more detail in this article. Some of the research findings were presented at theRead more
