Towards a Toolchain for Exploiting Smart Contracts on the Ethereum Blockchain
Towards a Toolchain for Exploiting Smart Contracts on the Ethereum Blockchain by Sebastian Kindler M.A., University of Bayreuth, 2011 Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Science in the Computer Science Program Faculty of Computer Science Supervisor: Prof. Dr. Stefan Traub Second Assessor: Prof. Dr. Markus Schäffter External Assessor: Dr. Henning Kopp Ulm University of Applied Sciences March 22, 2019 Abstract The present work introduces the reader to the Ethereum blockchain. First, on a con- ceptual level, explaining general blockchain concepts, and viewing the Ethereum blockchain in particular from different perspectives. Second, on a practical level, the main components that make up the Ethereum blockchain are explained in detail. In preparation for the objective of the present work, which is the analysis of EVM bytecode from an attacker’s perspective, smart contracts are introduced. Both, on the level of EVM bytecode and Solidity source code. In addition, critical assem- bly instructions relevant to the exploitation of smart contracts are explained in detail. Equipped with a definition of what constitutes a vulnerable contract, further practical and theoretical aspects are discussed: The present work introduces re- quirements for a possible smart contract analysis toolchain. The requirements are viewed individually, and theoretical focus is put on automated bytecode analysis and symbolic execution as this is the underlying technique of automated smart contract analysis tools. The importance of semantics is highlighted with respect to designing automated tools for smart contract exploitation. At the end, a min- imal toolchain is presented, which allows beginners to efficiently analyze smart contracts and develop exploits. -

Dezember 2016 Darmstadt 2017 Hochschulkennziffer: D17 Siegfried Rasthofer: Improving Mobile-Malware Investigations with Static and Dynamic Code Analysis Techniques © January 2017 phd referees: Prof. Dr. Eric Bodden Prof. Dr. Andreas Zeller Prof. Dr. Mira Mezini further phd committee members: Prof. Dr. Reiner Hähnle Prof. Dr. Christian Bischof Prof. Dr. Patrick Eugster Darmstadt, Germany January 2017 ABSTRACT Similar to the PC world, the abundance of mobile malware has become a serious threat to smartphone users. Thousands of new apps or app versions are uploaded to popular app stores every day. All of them need to be analyzed against violations of the app store’s content policy. In particular, one wishes to detect whether an application contains malicious behavior. Similarly, antivirus companies check thousands of apps every day to determine whether or not they are malicious. Both app store operators and antivirus vendors face the same problem: it is generally challenging to tell apart malware from benign applications. This is because malware developers aim to hide their applications’ malicious behavior as long as possible from being detected by applying different obfuscation techniques. The raising sophistication with which such measures are implemented pose a serious problem not just to automated malware detection approaches but also to the manual analysis of potential malware by human experts. -

Koja metoda će se koristiti ovisi o zahtjevnosti samog projekta, koliko ljudi radi na projektu, te u kojem vremenskom roku projekt mora biti isporučen. U svrhu ovog diplomskog rada razvijena je Android aplikacija putem tradicionalne metode, iako su danas sve više i više popularne takozvane agile metode. Agile, ili agilan, znači biti brz i sposoban reagirati na vrijeme te prilagoditi se svim promjenama u bilo kojem trenutku razvoja projekta. U radu su objašnjenje najpopularnije agile metode te su prikazane prednosti korištenja agile metoda u odnosu na tradicionalnu metodu. (37 stranica -
