Based on feedback and further monitoring, we investigated the polymorphic dropped executables in more detail. The results are quite interesting; the samples don\u00e2\u20ac\u2122t just feature trivial changes or the addition of random data. Rather, the sample appears like completely different software in many aspects. This allows the samples to avoid signature-based anti-virus as well as package detection and static analysis."
