Explanation

This page shows a different type of analysis done to each of the different binaries that we gather and have gathered in. Most malicious programs are packed with different technologies in the hopes of obfuscating their existing from different detection mechanisms, but to also increase the difficulty in either reverse engineering the binary, or to analyze what exact functions and purposes it may have. While there are many well used and semi-public packers in use, there is a trend for more private and custom packers being used to increase the effectiveness of their concealment.

The tool that we use to make the determination for identification is from Sigbuster by Toni Koivunen (toni <AT> teamfurry.com)/Teamfurry.com. Sigbuster is a cross-platform tool for detecting exe-packers.

Notes

There are minor discrepancies in the percentages, and this is an artifact from the numbers being compared to a set of five in the pie chart verses a set of ten in the table.
