Catching Malware En Masse: DNS and IP Style
summary
Presents concrete methods: a Hadoop batch + streaming DNS pipeline that extracts fast‑flux bipartite graphs, flags ~900 zbot fast‑flux domains (TTL 150s) serving Zeus, Pony and Andromeda, and finds .ru/.dosu-heavy IP pools and US-heavy clients; an IP analysis that fingerprints sub‑allocated /28–/30 blocks (OVH abuse, recycled IPs) and uses ASN topology plus BGP outage correlation to link sibling peripheral ASNs; a GPU‑accelerated 3D engine (OpenCL/OpenGL ES/GLSL, force‑directed layout) visualizes clusters; system achieves predictive IP blocking by quarantining suspect ranges before domains go live.
