Strider Web Security
Adversarial Web Crawling with Strider Monkeys Yi-Min Wang Director, Cyber-Intelligence Lab Internet Services Research Center (ISRC) Microsoft Research Search Engine Basics • Crawler – Crawling policy • Page classification & indexing • Static ranking • Query processing • Document-query matching & dynamic ranking – Diversity • Goals of web crawling – Retrieve web page content seen by browser users – Classify and index the content for search ranking • What is a monkey? – Automation program that mimics human user behavior Stateless Static Crawling • Assumptions – Input to the web server: the URL • Stateless client – Output from the web server: page content in HTML • Static crawler ignores scripts Stateful Static Crawling • We all know that Cookies affect web server response • HTTP User-Agent field affects response too – Some servers may refuse low-value crawlers – Some spammers use crawler-browser cloaking • Give crawlers a page that maximizes ranking (=traffic) • Give users a page that maximizes profit Dynamic Crawling • Simple crawler-browser cloaking can be achieved by returning HTML with scripts – Crawlers only parse static HTML text that maximizes ranking/traffic – Users’ browsers additionally execute the dynamic scripts that maximize profit • Usually redirect to a third-party domain to server ads • Need browser-based dynamic crawlers to index the true content Search Spam Example: Google search “coach handbag” Spam Doorway URL = http://coach-handbag-top.blogspot.com http://coach-handbag-top.blogspot.com/ script execution led to redirection -

Escape from Monkey Island: ? Evading High-Interaction Honeyclients
Escape from Monkey Island: ? Evading High-Interaction Honeyclients Alexandros Kapravelos1, Marco Cova2, Christopher Kruegel1, Giovanni Vigna1 1 UC Santa Barbara {kapravel,chris,vigna}@cs.ucsb.edu 2 University of Birmingham, UK {m.cova}@cs.bham.ac.uk Abstract. High-interaction honeyclients are the tools of choice to detect mali- cious web pages that launch drive-by-download attacks. Unfortunately, the ap- proach used by these tools, which, in most cases, is to identify the side-effects of a successful attack rather than the attack itself, leaves open the possibility for malicious pages to perform evasion techniques that allow one to execute an at- tack without detection or to behave in a benign way when being analyzed. In this paper, we examine the security model that high-interaction honeyclients use and evaluate their weaknesses in practice. We introduce and discuss a number of possible attacks, and we test them against several popular, well-known high- interaction honeyclients. Our attacks evade the detection of these tools, while successfully attacking regular visitors of malicious web pages. 1 Introduction In a drive-by-download attack, a user is lured into visiting a malicious web page, which contains code that exploits vulnerabilities in the user’s browser and/or its environment. If successful, the exploits can execute arbitrary code on the victim’s machine [33]. This ability is typically used to automatically download and run malware programs on the compromised machine, which, as a consequence, often becomes part of a botnet [31]. Drive-by-download attacks are one of the most pervasive threats on the web, and past measurements have found millions of malicious web pages [3, 32]. -
Lab Activity and Assignment #2
Lab Activity and Assignment #2 1 Introduction You just got an internship at Netfliz, a streaming video company. Great! Your first assignment is to create an application that helps the users to get facts about their streaming videos. The company works with TV Series and also Movies. Your app shall display simple dialog boxes and help the user to make the choice of what to see. An example of such navigation is shown below: Path #1: Customer wants to see facts about a movie: >> >> Path #2: Customer wants to see facts about a TV Series: >> >> >> >> Your app shall read the facts about a Movie or a TV Show from text files (in some other course you will learn how to retrieve this information from a database). They are provided at the end of this document. As part of your lab, you should be creating all the classes up to Section 3 (inclusive). As part of your lab you should be creating the main Netfliz App and making sure that your code does as shown in the figures above. The Assignment is due on March 8th. By doing this activity, you should be practicing the concept and application of the following Java OOP concepts Class Fields Class Methods Getter methods Setter methods encapsulation Lists String class Split methods Reading text Files Scanner class toString method Override superclass methods Scanner Class JOptionPane Super-class sub-class Inheritance polymorphism Class Object Class Private methods Public methods FOR loops WHILE Loops Aggregation Constructors Extending Super StringBuilder Variables IF statements User Input And much more.. -

Tracking and Mitigation of Malicious Remote Control Networks
Tracking and Mitigation of Malicious Remote Control Networks Inauguraldissertation zur Erlangung des akademischen Grades eines Doktors der Naturwissenschaften der Universität Mannheim vorgelegt von Thorsten Holz aus Trier Mannheim, 2009 Dekan: Prof. Dr. Felix Christoph Freiling, Universität Mannheim Referent: Prof. Dr. Felix Christoph Freiling, Universität Mannheim Korreferent: Prof. Dr. Christopher Krügel, University of California, Santa Barbara Tag der mündlichen Prüfung: 30. April 2009 Abstract Attacks against end-users are one of the negative side effects of today’s networks. The goal of the attacker is to compromise the victim’s machine and obtain control over it. This machine is then used to carry out denial-of-service attacks, to send out spam mails, or for other nefarious purposes. From an attacker’s point of view, this kind of attack is even more efficient if she manages to compromise a large number of machines in parallel. In order to control all these machines, she establishes a malicious remote control network, i.e., a mechanism that enables an attacker the control over a large number of compromised machines for illicit activities. The most common type of these networks observed so far are so called botnets. Since these networks are one of the main factors behind current abuses on the Internet, we need to find novel approaches to stop them in an automated and efficient way. In this thesis we focus on this open problem and propose a general root cause methodology to stop malicious remote control networks. The basic idea of our method consists of three steps. In the first step, we use honeypots to collect information. -

The Electrical Transformation of the Public Sphere: Home Video, the Family, and the Limits of Privacy in the Digital Age
THE ELECTRICAL TRANSFORMATION OF THE PUBLIC SPHERE: HOME VIDEO, THE FAMILY, AND THE LIMITS OF PRIVACY IN THE DIGITAL AGE By Adam Capitanio A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY American Studies 2012 ABSTRACT THE ELECTRICAL TRANSFORMATION OF THE PUBLIC SPHERE: HOME VIDEO, THE FAMILY, AND THE LIMITS OF PRIVACY IN THE DIGITAL AGE By Adam Capitanio One of the constituent features of the digital age has been the redrawing of the line between private and public. Millions of social media users willingly discuss intimate behavior and post private photographs and videos on the internet. Meanwhile, state and corporate bodies routinely violate individual privacy in the name of security and sophisticated marketing techniques. While these occurrences represent something new and different, they are unsurprising given the history of home and amateur media. In this dissertation, I argue that contemporary shifts in the nature of the public/private divide have historical roots in the aesthetics and style found in home movies and videos. In other words, long before Facebook and YouTube enabled users to publicly document their private lives, home movies and videos generated patterns of representation that were already shifting the unstable constitution of the “private” and the “public” spheres. Using critical theory and archival research, I demonstrate how home moviemakers represented their families and experiences in communal and liminal spaces, expanding the meaning of “home.” When video become the predominant medium for domestic usage, home mode artifacts became imbricated with television, granting them a form of phantasmagoric publicity that found fulfillment in the digital era.
