Fast-flux Attacks

Shijie Zhou - University of Electronic Science and Technology of China

Jan 27, 2010

Abstract

"Fast-flux" refers to rapidly assign different IP addresses to the same domain name. Although some legitimate uses with this technique are known, it has within the recent years become a favorite tool for cyber criminals to launch collaborative attacks. After it was first observed by Honeynet, it was reported that fast-flux has been used in phishing, malware spreading, spam, and other malicious activities linked to criminal organizations. Combining with peer-to-peer networking, distributed command and control, web-based load balancing and proxy redirection, fast-flux makes Internet attacks more resistant to discovery and counter-measure.
This discussion will introduce the comprehensive survey on fast-flux attacks. Some important issues including technical background, classification, characterization, detection and measurement, and mitigation are discussed. Challenges of detecting and mitigating fast-flux attack are also pointed out. Some our current researches, including modeling and detecting fast-flux attack, is also addressed.
