Automatic Generation of Attacker Contracts in Solidity

Abstract
Smart contracts on the Ethereum blockchain continue to suffer from well-published problems. A particular example is the well-known smart contract reentrancy vulnerability, which continues to be exploited. In this article, we present preliminary work on a method which, given a smart contract that may be vulnerable to such a reentrancy attack, proceeds to attempt to automatically derive an "attacker" contract which can be used to successfully attack the vulnerable contract. The method uses property-based testing to generate, semi-randomly, large numbers of potential attacker contracts, and then proceeds to check whether any of them is a successful attacker. The method is illustrated using a case study where an attack is derived for a vulnerable contract.

Synthesis of Logic Programs from Object-Oriented Formal Specifications

Authors: Ángel Herranz and Julio Mariño

Published in: LIPIcs, Volume 11, Technical Communications of the 27th International Conference on Logic Programming (ICLP'11) (2011)


Abstract
Early validation of requirements is crucial for the rigorous development of software. Without it, even the most formal of the methodologies will produce the wrong outcome. One successful approach, popularised by some of the so-called lightweight formal methods, consists in generating (finite, small) models of the specifications. Another possibility is to build a running prototype from those specifications. In this paper we show how to obtain executable prototypes from formal specifications written in an object oriented notation by translating them into logic programs. This has some advantages over other lightweight methodologies. For instance, we recover the possibility of dealing with recursive data types as specifications that use them often lack finite models.
