  • Internet Infrastructure Review Vol.15 -Infrastructure Security
    1. Infrastructure Security The Revised Unauthorized Computer Access Law In this volume we examine the revised Unauthorized Computer Access Law, and discuss the DNS Changer malware as well as the Ghost Domain Name issue relating to DNS. Infrastructure Security 1.1 Introduction This report summarizes incidents to which IIJ responded, based on general information obtained by IIJ itself related to the stable operation of the Internet, information from observations of incidents, information acquired through our services, and information obtained from companies and organizations with which IIJ has cooperative relationships. This volume covers the period of time from January 1 to March 31, 2012. Following on from the previous period, with an increase in the number of smartphone users, there have been an increasing number of problems related to the handling of information on the devices and user information. Hacktivism-based attacks such as those by Anonymous also continued to occur, and the number of attacks on companies and government agencies remained at a high level. In Middle-Eastern countries and Israel there were a series of hacking incidents and information leaks, as well as DDoS attacks on websites including critical infrastructure. Regarding vulnerabilities, an issue was discovered and fixed in multiple cache DNS server implementations including BIND. As seen above, the Internet continues to experience many security-related incidents. 1.2 Incident Summary Here, we discuss the IIJ handling and response to incidents Other 19.7% Vulnerabilities 20.6% that occurred between January 1 and March 31, 2012.

  • Munkavállalói Adatok Szivárogtak Az Nvidiatól
    Munkavállalói adatok szivárogtak az Nvidiatól 2015.01.05. 09:58 | Csizmazia Darab István [Rambo] | Szólj hozzá! Címkék: nvidia jelszó incidens security adatszivárgás jelszócsere breach welivesecurity.com A nagy adatlopási ügyek mellett történnek azért rendre "kisebb" horderejű, de azért szintén fontos biztonsági incidensek is, amelyek szintén nem tanulság nélkül valóak. Ezúttal az Nvidia háza táján történt olyan, dolgozói adatokat érintő adatlopás még decemberben, amely miatt a cég jelszóváltoztatásra és óvatosságra figyelmeztette saját munkavállalóit. A Forbes beszámolója szerint a jelszavak azonnali megváltoztatása mellett arra is kiemelten felhívták a figyelmet, hogy fokozott óvatossággal kezeljenek minden kéretlen levélben érkező adathalász próbálkozást. Ilyen esetekben ugyanis a kiszivárgott személyes információk birtokában sokszor testre-szabott, személyes hangvételű banki vagy látszólag munkatársak, barátok nevében érkező, és jelszavainkkal kapcsolatos kéréseket tartalmazó phishing megkeresések is érkezhetnek. A fenti hamis megkeresési trükkök mellett a dolgozóknak érdekes módon általában nehezükre esik elfogadni a valóságos belső fenyegetés veszélyét is, pedig a támadások, adatszivárgások alkalmával számos esetben van valamilyen belső szál is. Emellett emlékezetes lehet, hogy annak idején több mint 20 olyan embert azonosítottak, akik simán megadták az azonosítójukat és a jelszavukat Snowdennek, aki kollégái hozzáférését is felhasználta az adatgyűjtései és kiszivárogtatásai során. Mivel az eset több, mint 500 dolgozót is érinthetett,

Organizations and Cyber crime: An Analysis of the Nature of Groups engaged in Cyber Crime Roderic Broadhurst,1 Peter Grabosky,2 Mamoun Alazab3 & Steve Chon4 ANU Cybercrime Observatory, Australian National University, Australia Abstract This paper explores the nature of groups engaged in cyber crime. It briefly outlines the definition and scope of cyber crime, theoretical and empirical challenges in addressing what is known about cyber offenders, and the likely role of organized crime groups. The paper gives examples of known cases that illustrate individual and group behaviour, and motivations of typical offenders, including state actors. Different types of cyber crime and different forms of criminal organization are described drawing on the typology suggested by McGuire (2012). It is apparent that a wide variety of organizational structures are involved in cyber crime. Enterprise or profit-oriented activities, and especially cyber crime committed by state actors, appear to require leadership, structure, and specialisation. By contrast, protest activity tends to be less organized, with weak (if any) chain of command. Keywords: Cybercrime, Organized Crime, Crime Groups; Internet Crime; Cyber Offenders; Online Offenders, State Crime.

  • ERT Threat Alert Opisrael2016 Update April 5, 2016
    ERT Threat Alert OpIsrael2016 Update April 5, 2016 Abstract With the stated goal of “erasing Israel from the internet” in protest against claimed crimes against the Palestinian people, Anonymous will launch its yearly operation against Israel. Named OpIsrael, it is a cyber-attack timed for April 7th by an array of hacktivist groups that join forces with the greater Anonymous collective (see Figure 1). For this year’s attack, hackers have provided tools and technical guidance for the execution of OpIsrael. Figure 1: OpIsrael Announcement In past years, Israel has seen moderate attacks launched against its networks and infrastructure. Organizations should take precautions and make sure they are prepared for OpIsrael2016. Since the previous ERT alert outlining OpIsrael, Radware’s Emergency Response Team has identified new hacktivist groups planning to partake in these cyber assaults and new attack vectors/tools that will be used. This alert enhances our initial findings and is updated to provide guidance on how targeted organizations can keep their networks and applications protected from these attacks. Background Ideological, political and religious differences are at the core of this operation. Since 2012, Anonymous has launched a yearly campaign in protest against the Israeli governments conduct in the Israeli- Palestinian conflict. Every year, OpIsrael calls for dozens of different hacktivist groups to “hack, deface, hijack, leak databases, admin takeover and DNS terminate” targets associated with Israel. Well known for its advanced technological capabilities, Israel poses a challenge for hackers. Those that attempt and overcome those challenges win prestige and recognition for their expertise inside their communities. In previous years Israel and Israelis have seen modems hacked, credit card data breached government and personal information posted, Facebook accounts hijacked, websites defaced, emails leaked and a series of network crippling denial of service attacks.

    [Recognising Botnets in Organisations] Barry Weymes Number: 662 A thesis submitted to the faculty of Computer Science, Radboud University in partial fulfillment of the requirements for the degree of Master of Science Eric Verheul, Chair Erik Poll Sander Peters (Fox-IT) Department of Computer Science Radboud University August 2012 Copyright © 2012 Barry Weymes Number: 662 All Rights Reserved ABSTRACT [Recognising Botnets in Organisations] Barry WeymesNumber: 662 Department of Computer Science Master of Science Dealing with the raise in botnets is fast becoming one of the major problems in IT. Their adaptable and dangerous nature makes detecting them difficult, if not impossible. In this thesis, we present how botnets function, how they are utilised and most importantly, how to limit their impact. DNS Dynamic Reputations Systems, among others, are an innovative new way to deal with this threat. By indexing individual DNS requests and responses together we can provide a fuller picture of what computer systems on a network are doing and can easily provide information about botnets within the organisation. The expertise and knowledge presented here comes from the IT security firm Fox-IT in Delft, the Netherlands. The author works full time as a security analyst there, and this rich environment of information in the field of IT security provides a deep insight into the current botnet environment. Keywords: [Botnets, Organisations, DNS, Honeypot, IDS] ACKNOWLEDGMENTS • I would like to thank my parents, whom made my time in the Netherlands possible. They paid my tuition, and giving me the privilege to follow my ambition of getting a Masters degree. • My dear friend Dave, always gets a mention in my thesis for asking the questions other dont ask.

  • Automatic Detection of Malware-Generated Domains with Recurrent Neural Models
    Automatic Detection of Malware-Generated Domains with Recurrent Neural Models Pierre Lison1, Vasileios Mavroeidis2 1Norwegian Computing Center, Oslo, Norway 2University of Oslo, Oslo, Norway Abstract Modern malware families often rely on domain-generation algorithms (DGAs) to determine rendezvous points to their command-and-control server. Traditional defence strategies (such as blacklisting domains or IP addresses) are inadequate against such techniques due to the large and continuously changing list of domains produced by these algorithms. This paper demonstrates that a machine learning approach based on recurrent neural networks is able to detect domain names generated by DGAs with high precision. The neural models are estimated on a large training set of domains generated by various malwares. Experimental results show that this data-driven approach can detect malware-generated domain names with a F1 score of 0.971. To put it differently, the model can automatically detect 93 % of malware-generated domain names for a false positive rate of 1:100. 1 Introduction Most malware need to find a way to connect compromised machines with a command- and-control (C2) server in order to conduct their operations (such as launching denial- of-service attacks, executing ransomware, stealing user data, etc.). To establish such a communication channel, older families of malware relied on static lists of domains or IP addresses that were hardcoded in the malware code running on the infected hosts. Once a given malware was discovered, it could then be neutralised by blocking the connections to these network addresses to prevent further communications between the infected hosts and the C2 server.
