Honeyd (N. Provos, 2004) is a popular tool developed by Niels Provos that offers a simple way to emulate services offered by several machines on a single PC. It is a so called low interaction honeypot. Responses to incoming requests are generated thanks to ad hoc scripts that need to be written by hand. As a result, few scripts exist, especially for(More)
Spitzner proposed to classify honeypots into low, medium and high interaction ones. Several instances of low interaction exist, such as honeyd, as well as high interaction, such as GenII. Medium interaction systems have recently received increased attention. ScriptGen and RolePlayer, for instance, are as talkative as a high interaction system while limiting(More)
Abstract. Rogue antivirus software has recently received extensive attention, justified by the diffusion and efficacy of its propagation. We present a longitudinal analysis of the rogue antivirus threat ecosystem, focusing on the structure and dynamics of this threat and its economics. To that end, we compiled and mined a large dataset of characteristics of(More)
This paper aims at presenting in some depth the project and its data collection infrastructure. Launched in 2003 by the Institut Eurecom, this project is based on a worldwide distributed system of honeypots running in more than 30 different countries. The main objective of the project is to get a more realistic picture of certain classes of(More)
The dependability community has expressed a growing interest in the recent years for the effects of malicious, external, operational faults in computing systems, ie. intrusions. The term intrusion tolerance has been introduced to emphasize the need to go beyond what classical fault tolerant systems were able to offer. Unfortunately, as opposed to well(More)
We are witnessing an increasing complexity in the malware analysis scenario. The usage of polymorphic techniques generates a new challenge: it is often difficult to discern the instance of a known polymorphic malware from that of a newly encountered malware family, and to evaluate the impact of patching and code sharing among malware writers in order to(More)
Fault tolerance in the form of diverse redundancy is well known to improve the detection rates for both malicious and non-malicious failures. What is of interest to designers of security protection systems are the actual gains in detection rates that they may give. In this paper we provide exploratory analysis of the potential gains in detection capability(More)
This paper focuses on the containment and control of the network interaction generated by malware samples in dynamic analysis environments. A currently unsolved problem consists in the existing dependency between the execution of a malware sample and a number of external hosts (e.g. C&C servers). This dependency affects the repeatability of the(More)
We present in this paper SGNET, a distributed framework to collect information on Internet attacks, with special attention to self-propagating malware and code injections. This framework is the result of our latest research work on the so-called ScriptGen technology. It is characterized by several unique characteristics that may allow it to provide in the(More)
The interest for the research community to measure the Internet has grown tremendously during the last couple of years. This increase of interest is largely due to the growth and expansion of the Internet that has been overwhelming. We have experienced exponential growth in terms of traffic volumes and number of devices connected to the Internet. In(More)
