Thanks are due also to Marta Es¨o,who wrote an early draft of this manual for what was then COMPSys. This release would not have been possible without the help of both Menal G¨uzelsoy, who has been instrumental in the development of SYMPHONY since version 4.0, and Ashutosh Mahajan, who has worked on SYMPHONY since version 5.0. In particular, Ashutosh and Menal did all of the work that went into improving SYMPHONY for release 5.2.

  • Cracking the Lens: Targeting HTTP's Hidden Attack Surface
    Cracking the Lens: Targeting HTTP's Hidden Attack Surface James Kettle - [email protected] - @albinowax Modern websites are browsed through a lens of transparent systems built to enhance performance, extract analytics and supply numerous additional services. This almost invisible attack surface has been largely overlooked for years. In this paper, I'll show how to use malformed requests and esoteric headers to coax these systems into revealing themselves and opening gateways into our victim's networks. I'll share how by combining these techniques with a little Bash I was able to thoroughly perforate DoD networks, trivially earn over $30k in vulnerability bounties, and accidentally exploit my own ISP. While deconstructing the damage, I'll also showcase several hidden systems it unveiled, including not only covert request interception by the UK's largest ISP, but a substantially more suspicious Colombian ISP, a confused Tor backend, and a system that enabled reflected XSS to be escalated into SSRF. You'll also learn strategies to unblinker blind SSRF using exploit chains and caching mechanisms. Finally, to further drag these systems out into the light, I'll release Collaborator Everywhere - an open source Burp Suite extension which augments your web traffic with a selection of the best techniques to harvest leads from cooperative websites. Outline Introduction Methodology Listening Research Pipeline Scaling Up Misrouting Requests Invalid Host Investigating Intent - BT Investigating Intent - Metrotel Input Permutation Host Override Ambiguous Requests Breaking Expectations Tunnels Targeting Auxiliary Systems Gathering Information Remote Client Exploits Preemptive Caching Conclusion Introduction Whether it's ShellShock, StageFright or ImageTragick, the discovery of a serious vulnerability in an overlooked chunk of attack surface is often followed by numerous similar issues.

  • Design and Analysis of Adaptive Caching Techniques for Internet Content Delivery
    Dissertation Design and Analysis of Adaptive Caching Techniques for Internet Content Delivery Thesis approved by the Department of Computer Science of the University of Kaiserslautern (TU Kaiserslautern) for the award of the Doctoral Degree Doctor of Engineering (Dr.-Ing.) to Daniel S. Berger Date of the viva : June 8, 2018 Dean : Prof. Dr. Stefan Deßloch PhD committee Chair : Prof. Dr. Pascal Schweitzer Reviewers : Prof. Dr. Jens B. Schmitt Prof. Dr. Florin Ciucu (University of Warwick) Prof. Dr. Mor Harchol-Balter (Carnegie Mellon University) D 386 Abstract Fast Internet content delivery relies on two layers of caches on the request path. Firstly, content delivery networks (CDNs) seek to answer user requests before they traverse slow Internet paths. Secondly, aggregation caches in data centers seek to answer user requests before they traverse slow backend systems. The key challenge in managing these caches is the high variability of object sizes, request patterns, and retrieval latencies. Unfortunately, most existing literature focuses on caching with low (or no) variability in object sizes and ignores the intricacies of data center subsystems. This thesis seeks to fill this gap with three contributions. First, we design a new caching system, called AdaptSize, that is robust under high object size variability. Sec- ond, we derive a method (called Flow-Offline Optimum or FOO) to predict the optimal cache hit ratio under variable object sizes. Third, we design a new caching system, called RobinHood, that exploits variances in retrieval latencies to deliver faster responses to user requests in data centers. The techniques proposed in this thesis significantly improve the performance of CDN and data center caches.
