Towards Next-Generation Botnets

This paper introduces the design of an advanced bot called Rambot that is based on the weak nesses found when tracking a diverse set of botnets over a period of several months. The main features of this bot are peer-to-peer communication, strong cryptography, a credit-point system to build bilateral trust...

As the Net Churns: Fast-Flux Botnet Observations

While botnets themselves provide a rich platform for financial gain for the botnet master, the use of infected hosts as webservers can provide an additional botnet use. Botnet herders often use fast-flux DNS techniques to host unwanted or illegal content within a botnet. These techniques change the mapping of domain...

Measurements and Mitigation of Peer-to-Peer-Based Botnets: A Case Study on Storm Worm

Botnets, i.e., networks of compromised machines under a common control infrastructure, are commonly controlled by an attacker with the help of a central server: all compromised machines connect to the central server and wait for commands. However, the first botnets that use Peer-to-Peer (P2P) networks for remote control of the...

Scalable Position-Based Multicast for Mobile Ad-Hoc Networks

This paper presents Scalable Position-Based Multicast SPBM, a multicast routing protocol for ad-hoc networks. SPBM uses the geographic position of nodes to provide a highly scalable group membership scheme and to forward data packets with a very low overhead. SPBM bases its multicast forwarding decision on whether there are group...

Declarative Development of Distributed Applications

This paper presents an approach for the convenient implementation and efficient execution of distributed XML message processing applications. Various application classes such as Web Services are based on asynchronously exchanging XML data. However, today's programming languages and execution systems fail to support their particular demands such as integrated XML type...

A Generic Toolkit for Converting Web Applications Into High-Interaction Honeypots

This paper presents the design and implementation of a generic toolkit for turning arbitrary PHP web applications into high interaction honeypots in an automated fashion. The authors demonstrate the wide applicability of this approach by applying it to four popular existing web applications. Moreover, they show the effectiveness of the...

Towards Intrusion Detection in Wireless Sensor Networks

The work discussed in this paper studies the problem of Intrusion Detection which is sensor networks and propose a lightweight scheme that can be applied to such networks. Its basic characteristic is that nodes monitor their neighborhood and collaborate with their nearest neighbors to bring the network back to its...

Researchers map China's underground cybercrime economy

Researchers from Peking University in Beijing and the University of Mannheim in Germany released a paper this week that aims to map the underground cybercrime economy in China. The paper concludes that 1.49 percent of the 145,000 most popular sites in China "contain some kind of malicious content." While...
