Tracing HTTP Activity Through Non-cooperating HTTP Proxies (Short Paper) [chapter]

Richard J. Edell, Peter Kruus, Uri Meth
2006 Lecture Notes in Computer Science  
This paper describes a technique for tracing HTTP traffic through one or more non-cooperating HTTP (and/or SOCKS) proxies. The technique uses only passive observations of TCP/IP headers.  ...  Tracing nefarious HTTP activity to its source is sometimes extremely difficult when HTTP (and/or SOCKS) proxies are used for origin obfuscation.  ...  This paper describes our HTTP traceback technique for tracing HTTP activity backwards, from the destination server, through some non-cooperating HTTP proxies, and toward the origin of the activity.  ...

Experiences with CoralCDN: A Five-Year Operational View

Michael J. Freedman
2010 Symposium on Networked Systems Design and Implementation  
Publishing through CoralCDN is as simple as making a small change to a URL's hostname; a decentralized DNS layer transparently directs browsers to nearby participating cache nodes, which in turn cooperate  ...  This paper describes CoralCDN's usage scenarios and a number of experiences drawn from its multi-year deployment.  ...  The CoralCDN HTTP proxy CoralCDN seeks to aggressively minimize load on origin servers. This section summarizes how its proxies use Coral for inter-proxy cooperation and adaptation to flash crowds.  ...

An effective defense against email spam laundering

Mengjun Xie, Heng Yin, Haining Wang
2006 Proceedings of the 13th ACM conference on Computer and communications security - CCS '06  
In this paper, we reveal one salient characteristic of proxy-based spamming activities, namely packet symmetry, by analyzing protocol semantics and timing causality.  ...  We implement a prototype of DBSpam based on libpcap, and validate its efficacy through both theoretical analyses and trace-based experiments.  ...  Clearly, the short-living spamming activities are missed by DBSpam, with zero detection for S-*-A traces and much fewer detections for S-2-B and S-2-C traces.  ...

Geolocalization of proxied services and its application to fast-flux hidden servers

Claude Castelluccia, Mohamed Ali Kaafar, Pere Manils, Daniele Perito
2009 Proceedings of the 9th ACM SIGCOMM conference on Internet measurement conference - IMC '09  
These experimentations showed that, with our framework, fast-flux servers can be localized with similar mean distance errors than non-hidden servers, i.e. approximately 100 km.  ...  This paper proposes a framework to geolocalize fast-flux servers, that is, to determine the physical location of the fast-flux networks roots (mothership servers) based on network measurements.  ...  that the landmark is aware of, and HT T P _P ing(Li, p, HS) is the time spent from the TCP connection initiation to the reception of the first HTTP packet from the hidden server, through the proxy p.  ...

Evading Censorship with Browser-Based Proxies [chapter]

David Fifield, Nate Hardison, Jonathan Ellithorpe, Emily Stark, Dan Boneh, Roger Dingledine, Phil Porras
2012 Lecture Notes in Computer Science  
Often these proxies are blocked as soon as they are discovered. In this paper we propose a browser-based proxy creation system that generates a large number of short-lived proxies.  ...  We show that browser-based short-lived proxies provide adequate bandwidth for video delivery and argue that blocking them can be challenging.  ...  We then started between 1 and 50 simultaneous HTTP downloads of a 10 MB file directly over TCP, through a WebSocket proxy, and through a Flash-based proxy.  ...

Squeezing more bits out of HTTP caches

J.C. Mogul
2000 IEEE Network  
This article surveys several techniques, and reports the results of trace-based studies of a proposal based on automatic recognition of duplicated content.  ...  Traditional Web caches store HTTP responses, in anticipation of a subsequent reference to the URL of a cached response.  ...  The input reference stream can be either a real stream, captured by tracing the references of actual users, or a stream generated by a model of user activity.  ...
