Web1 day ago · To scale accurate analysis to modern smart contracts, we introduce EF/CF, a high-performance fuzzer for Ethereum smart contracts. In contrast to previous work, EF/CF efficiently and accurately models complex smart contract interactions, such as reentrancy and cross-contract interactions, at a very high fuzzing throughput rate. WebIn order to simulate the attacks at multi input points for the fuzzing, in this paper, we present a white-box combinatorial fuzzing framework based on symbolic execution and …

Ferry: State-Aware Symbolic Execution for Exploring State

Websymbolically-assisted fuzzing identiﬁed almost three times more vulnerabilities than symbolic execution [39]. The number of developed techniques aiming to improve fuzzing grows [28] — sometimes without fully-functioning code, if at all. In addition, fuzzing techniques are often devel-oped orthogonally and independently, so combining them can WebSymbolic execution. The key idea behind this technique is to execute a program over symbolic, rather than concrete, inputs. Each symbolic input can, for instance, represent … how to start pc in repair mode

WebFor symbolic execution we use Symbolic PathFinder (SPF), a symbolic execution tool for Java bytecode [26]. We modified SPF by adding a mixed concrete-symbolic execution mode, similar to concolic execution [27] which allows us to import the inputs generated on the fuzzing side and quickly reconstruct the symbolic WebDec 14, 2024 · Simple. Symbolic execution is "hard". Format-aware dynamic analysis is much simpler to implement with good results.

Instead of using concrete inputs, symbolic execution executes a program with symbolic inputs. During execution, a symbolic execution engine accumulates a set of constraints on the symbolic inputs.

WebFuzzing is a technique of finding bugs by executing a software recurrently with a large number of abnormal inputs. Most of the existing fuzzers consider all parts of a software equally, and pay too much attention on how to improve the code coverage. It is inefficient as the vulnerable code only takes a tiny fraction of the entire code. Websymbolic execution is a means of analyzing a program to determine what inputs cause each part of a program to execute. An interpreter follows the program, assuming symbolic values for inputs rather than obtaining …

Symbolic execution is a software testing technique that substitutes the normal inputs into a program(e.g. numbers) through symbolic values (formulae)during the program execution. When program execution branches … See more As opposed to traditional fuzzers, which generate inputs without taking code structure into account, symbolic execution tools precisely … See more Although Driller marked significant research advances in the field of symbolic execution, it is still a highly specialized tool that requires expert knowledge to set up and run and uses up a lot of computational resources.
