TLDR
This work analyses the security vulnerabilities of Ethereum smart contracts, providing a taxonomy of common programming pitfalls which may lead to vulnerabilities, and shows a series of attacks which exploit these vulnerabilities, allowing an adversary to steal money or cause other damage.Abstract:
Smart contracts are computer programs that can be correctly executed by a network of mutually distrusting nodes, without the need of an external trusted authority. Since smart contracts handle and transfer assets of considerable value, besides their correct execution it is also crucial that their implementation is secure against attacks which aim at stealing or tampering the assets. We study this problem in Ethereum, the most well-known and used framework for smart contracts so far. We analyse the security vulnerabilities of Ethereum smart contracts, providing a taxonomy of common programming pitfalls which may lead to vulnerabilities. We show a series of attacks which exploit these vulnerabilities, allowing an adversary to steal money or cause other damage.read more

Demystifying Exploitable Bugs in Smart Contracts
Brian Zhang,Wen Xu,Zhiqiang Lin +2 more
TL;DR: In this paper , the authors systematically investigate 516 unique real-world smart contract vulnerabilities in years 2021-2022, and study how many can be exploited by malicious users and cannot be detected by existing analysis tools.

Detect Abnormal Behaviours in Ethereum Smart Contracts Using Attack Vectors
TL;DR: This paper classify attack vectors of Ethereum smart contracts, then proposes some behaviour-based methods to detect them, and implements Abbe, a tool that can not only discover known attacks but also detect zero-day vulnerabilities.

Rethinking Smart Contract Fuzzing: Fuzzing With Invocation Ordering and Important Branch Revisiting
TL;DR: IR-Fuzz as discussed by the authors proposes a branch distance-based measure to evolve test cases iteratively towards a target branch, and employs a branch search algorithm to discover rare and vulnerable branches, and design an energy allocation mechanism to take care of exercising these crucial branches.

Developing Safe Smart Contracts
TL;DR: It is shown how the actor model can be used for modeling, analysis and synthesis of smart contracts, and a synthesizer is implemented to synthesize Solidity programs that run on the Ethereum platform from Smart Rebeca models.

Ethereum: A Secure Decentralised Generalised Transaction Ledger
TL;DR: Ethereum as mentioned in this paper is a transactional singleton machine with shared state, which can be seen as a simple application on a decentralised, but singleton, compute resource, and it provides a plurality of resources, each with a distinct state and operating code but able to interact through a message-passing framework with others.

Making Smart Contracts Smarter
TL;DR: This paper investigates the security of running smart contracts based on Ethereum in an open distributed network like those of cryptocurrencies, and proposes ways to enhance the operational semantics of Ethereum to make contracts less vulnerable.
