  • Detection of Distributed Denial-Of-Service Attacks in Encrypted Network Traffic
    Mikko Hyvärinen Detection of Distributed Denial-of-Service Attacks in Encrypted Network Traffic Master’s Thesis in Information Technology December 9, 2016 University of Jyväskylä Department of Mathematical Information Technology Author: Mikko Hyvärinen Contact information: [email protected] Supervisor: Timo Hämäläinen & Mikhail Zolotukhin Title: Detection of Distributed Denial-of-Service Attacks in Encrypted Network Traffic Työn nimi: Hajautettujen palvelunestohyökkäysten havainnointi salatussa verkkoliiken- teessä Project: Master’s Thesis Study line: Software Development Page count: 122+9 Abstract: Context: Distributed denial-of-service attacks have existed for two decades. Var- ious strategies have been developed to combat the increasing volume of attacks over the years. Application layer attacks are becoming more common, and they are harder to detect. Current detection methods analyze traffic features. The packet payload is encrypted in an SSL/TLS traffic, and it cannot be analyzed. Objective: The thesis studies the current situa- tion of detection of DDoS attacks in an SSL/TLS encrypted traffic. Also, the thesis presents a K-means++ clustering-based detection method and comparable simulation results with the previous literature. Methods: The author conducted a light systematic mapping study by searching common computer science literature libraries. The author ran experiments with the clustering-based method in a virtual network. Results: The mapping study found that the detection methods concentrate on clustering and statistical anomaly detection methods. In the experiments, denial-of-service attack simulations revealed that the K-means++ clus- tering detects trivial DDoS attacks with near 100% accuracy. Datasets were found to be an important part when comparing results. Conclusion: The mapping study revealed encrypted denial-of-service research study areas where more research is needed when compared to the non-encrypted counterpart.

Join ASML as an Electronics Engineer and help push the boundaries of technology. As one of the world’s leading providers of lithography systems for the semiconductor industry, we bring together the most creative minds in science and technology to help produce increasingly cheaper, faster and more energy-efficient microchips. For the past 30 years, we’ve been helping to realize Moore’s law. Now we want to go even further: to enable the tripling, or even the quadrupling of chip-feature density every two years. That’s why we need talented Electronics Engineers. People who can, for example, increase the speed and the precision of our systems integration, and thereby enable future logic gates no bigger than a few silicon atoms. It’s just one of the many electronics challenges at ASML. And there are countless more – all targeted at achieving more than Moore’s prediction. If you’re up for these challenges, we’ll put you in a multidisciplinary team and give you plenty of freedom to experiment and learn new skills.

  • Effective DGA-Domain Detection and Classification with Textcnn
    electronics Article Effective DGA-Domain Detection and Classification with TextCNN and Additional Features Chanwoong Hwang 1 , Hyosik Kim 1, Hooki Lee 2 and Taejin Lee 1,* 1 Department of Information Security, Hoseo University, Asan 31499, Korea; [email protected] (C.H.); [email protected] (H.K.) 2 Department of Cyber Security Engineering, Konyang University, Nonsan 32992, Korea; [email protected] * Correspondence: [email protected] Received: 8 June 2020; Accepted: 29 June 2020; Published: 30 June 2020 Abstract: Malicious codes, such as advanced persistent threat (APT) attacks, do not operate immediately after infecting the system, but after receiving commands from the attacker’s command and control (C&C) server. The system infected by the malicious code tries to communicate with the C&C server through the IP address or domain address of the C&C server. If the IP address or domain address is hard-coded inside the malicious code, it can analyze the malicious code to obtain the address and block access to the C&C server through security policy. In order to circumvent this address blocking technique, domain generation algorithms are included in the malware to dynamically generate domain addresses. The domain generation algorithm (DGA) generates domains randomly, so it is very difficult to identify and block malicious domains. Therefore, this paper effectively detects and classifies unknown DGA domains. We extract features that are effective for TextCNN-based label prediction, and add additional domain knowledge-based features to improve our model for detecting and classifying DGA-generated malicious domains. The proposed model achieved 99.19% accuracy for DGA classification and 88.77% accuracy for DGA class classification.

  • Cross-Analysis of Botnet Victims: New Insights and Implications
    Cross-Analysis of Botnet Victims: New Insights and Implications Seungwon Shin, Raymond Lin, and Guofei Gu SUCCESS Lab, Texas A&M University, College Station, Texas, USA {swshin,rlin,guofei}@cse.tamu.edu Abstract. In this paper, we analyze a large amount of infection data for three major botnets: Conficker, MegaD, and Srizbi. These botnets rep- resent two distinct types of botnets in terms of the methods they use to recruit new victims. We propose the use of cross-analysis between these different types of botnets as well as between botnets of the same type in order to gain insights into the nature of their infection. In this analysis, we examine commonly-infected networks which appear to be extremely prone to malware infection. We provide an in-depth passive and active measurement study to have a fine-grained view of the similarities and differences for the two infection types. Based on our cross-analysis re- sults, we further derive new implications and insights for defense. For example, we empirically show the promising power of cross-prediction of new unknown botnet victim networks using historic infection data of some known botnet that uses the same infection type with more than 80% accuracy. 1 Introduction Recent botnets use several methods to find and infect victims. Among these meth- ods, most botnets have mainly employed two infection techniques [9] [7] [6]: – Bots automatically propagate themselves (auto-self-propagating, Type I ). To do this, bots usually employ network scanning techniques to find vulnerable hosts and exploit them. This approach is active and aggressive in infecting victims.
