  • Practical Issues with TLS Client Certificate Authentication
    Practical Issues with TLS Client Certificate Authentication Arnis Parsovs Software Technology and Applications Competence Center, Estonia University of Tartu, Estonia [email protected] Abstract—The most widely used secure Internet communication Active security research is being conducted to improve standard TLS (Transport Layer Security) has an optional client password security, educate users on how to resist phishing certificate authentication feature that in theory has significant attacks, and to fix CA trust issues [1], [2]. However, the attacks security advantages over HTML form-based password authenti- mentioned above can be prevented or their impact can be cation. In this paper we discuss practical security and usability greatly reduced by using TLS client certificate authentication issues related to TLS client certificate authentication stemming (CCA), since the TLS CCA on the TLS protocol level protects from the server-side and browser implementations. In particular, we analyze Apache’s mod_ssl implementation on the server the client’s account on a legitimate server from a MITM side and the most popular browsers – Mozilla Firefox, Google attacker even in the case of a very powerful attacker who has Chrome and Microsoft Internet Explorer on the client side. We obtained a valid certificate signed by a trusted CA and who complement our paper with a measurement study performed in thus is able to impersonate the legitimate server. We believe Estonia where TLS client certificate authentication is widely used. that TLS CCA has great potential for improving Internet We present our recommendations to improve the security and security, and therefore in this paper we discuss current issues usability of TLS client certificate authentication.

  • How Anywhere Computing Just Killed Your Phone-Based Two-Factor Authentication
    How Anywhere Computing Just Killed Your Phone-Based Two-Factor Authentication Radhesh Krishnan Konothy, Victor van der Veeny, and Herbert Bos yEqual contribution joint first authors VU University Amsterdam, The Netherlands r:k:konoth@vu:nl;{vvdveen;herbertb}@cs:vu:nl Abstract. Exponential growth in smartphone usage combined with re- cent advances in mobile technology is causing a shift in (mobile) app behavior: application vendors no longer restrict their apps to a single platform, but rather add synchronization options that allow users to conveniently switch from mobile to PC or vice versa in order to access their services. This process of integrating apps among multiple platforms essentially removes the gap between them. Current, state of the art, mo- bile phone-based two-factor authentication (2FA) mechanisms, however, heavily rely on the existence of such separation. They are used in a vari- ety of segments (such as consumer online banking services or enterprise secure remote access) to protect against malware. For example, with 2FA in place, attackers should no longer be able to use their PC-based malware to instantiate fraudulent banking transactions. In this paper, we analyze the security implications of diminishing gaps between platforms and show that the ongoing integration and desire for increased usability results in violation of key principles for mobile phone 2FA. As a result, we identify a new class of vulnerabilities dubbed 2FA synchronization vulnerabilities. To support our findings, we present practical attacks against Android and iOS that illustrate how a Man- in-the-Browser attack can be elevated to intercept One-Time Passwords sent to the mobile phone and thus bypass the chain of 2FA mechanisms as used by many financial services.

We offer it to the public with the permission of Professor Schmidt. Google Data Collection Professor Douglas C. Schmidt, Vanderbilt University August 15, 2018 I. EXECUTIVE SUMMARY 1. Google is the world’s largest digital advertising company.1 It also provides the #1 web browser,2 the #1 mobile platform,3 and the #1 search engine4 worldwide. Google’s video platform, email service, and map application have over 1 billion monthly active users each.5 Google utilizes the tremendous reach of its products to collect detailed information about people’s online and real-world behaviors, which it then uses to target them with paid advertising. Google’s revenues increase significantly as the targeting technology and data are refined. 2. Google collects user data in a variety of ways. The most obvious are “active,” with the user directly and consciously communicating information to Google, as for example by signing in to any of its widely used applications such as YouTube, Gmail, Search etc. Less obvious ways for Google to collect data are “passive” means, whereby an application is instrumented to gather information while it’s running, possibly without the user’s knowledge. Google’s passive data gathering methods arise from platforms (e.g. Android and Chrome), applications (e.g.

With the advent of Web 2.0 , AJAX is being used widely • Using Jquery javascript library, to enhance interactivity and user experience. Also standalone AJAX applications are also being developed. For example, Google $(‘#test’).click(function() Maps, Gmail and Yahoo! Mail are classic examples of AJAX { applications. Current crawlers ignore AJAX content as well as test function(); dynamic content added through client side script. Thus most }); of the dynamic content is still hidden. This paper presents an AJAX Crawler and also discusses about the optimizations and issues regarding crawling AJAX. All the above 4 methods, perform the same function of adding the event onclick on element test. Thus event generating I. I NTRODUCTION elements cannot be identified in a standard way because of In a traditional web application, every page has a unique the numerous Javascript libraries that exist and each has URL , whereas in a AJAX application every state cannot be its own way of defining event handlers. So the approach represented by a unique URL. A particular URL may have a lot of clicking all the clickable elements is being followed. of states with different content. Dynamic content is added to Though this approach is time consuming and can cause the DOM(Document Object Model) through Javascript. Thus sub elements to be clicked repeatedly, it has the advantage an AJAX Crawler requires the ability to execute Javascript.

  • Enhancing the Security and Privacy of the Web Browser Platform Via Improved Web Measurement Methodology
    ABSTRACT JUECKSTOCK, JORDAN PHILIP. Enhancing the Security and Privacy of the Web Browser Platform via Improved Web Measurement Methodology. (Under the direction of Alexandros Kapravelos.) The web browser platform today serves as a dominant vehicle for commerce, communication, and content consumption, rendering the assessment and improvement of that platform’s user security and privacy important research priorities. Accurate web measurement via simulated user browsing across popular real-world web sites is essential to the process of assessing and improving web browser platform security and privacy, particularly when developing improved policies that can be deployed in production to millions of real-world users. However, the state of the art in web browser platform measurement instrumentation and methodology leaves much to be desired in terms of robust instrumentation, reproducible experiments, and realistic design parameters. We propose that enhancing web browser policies to improve privacy while retaining compatibility with legacy content requires robust and realistic web measurement methodologies leveraging deep browser instrumentation. This document comprises research results supporting the above-stated thesis. We demonstrate the limitations of shallow, in-band JavaScript (JS) instrumentation in web browsers, then describe and demonstrate an open source out-of-band instrumentation tool, VisibleV8 (VV8), embedded in the V8 JS engine. We show that VV8 consistently outperforms equivalent in-band instrumentation, provides coverage unavailable to in-band techniques, yet has proved readily maintainable across numerous updates to Chromium and the V8 JS engine. Next, we test the assumption, implicit in typical web measurement studies, that automated crawls generalize to the experience of typical web users with a robustly controlled parallel web measurement experiment comparing observations from multiple network vantage points (VP) and via naive or realistic browser configurations (BC).
