Analysis of internet-wide probing using darknets
Alberto Dainotti, Alistair King, kc claffy · 2012
Recent analysis of traffic reaching the UCSD Network Telescope (a /8 darknet) revealed a sophisticated botnet scanning event that covertly scanned the entire IPv4 space in about 12 days. We only serendipitously discovered this event while studying a completely unrelated behavior (censorship episode in Egypt in February 2011), but we carefully studied the scan, including validating and cross-correlating our observations with other large data set shared by others. We would like to extend these strategies to detect other large-scale malicious events. We suspect the fight against malware will benefit greatly (and perhaps require) collaborative sharing of diverse large-scale security-related data sets. We hope to discuss both the technical and the data-sharing policy aspects of this challenge at the workshop.
