In　this　study,　a　systematic　approach　to　Capturing　and　Analysing　botnets　is　presented.　Our　framework　is　a　scalable　and　robust　infrastructure　and　consists　of　four　modules.　Honeynet-based　capture　system　is　proposed　that　is　the　first　step　towards　our　framework,　which　can　automatically　and　dynamically　collect　and　analyze　malware　traffic　over　the　Internet　without　supervision.　Furthermore,　a　multidimensional　analysis　system　is　designed　to　analyze　binaries　captured　in　the　capture　system.　In　addition,　we　discuss　our　preliminary　results　and　lessons　learned　from　this　work.　©　2013　Asian　Network　for　Scientific　Information/.
