AFL(American Fuzzy Lop)是由安全研究员Michał Zalewski(@lcamtuf)开发的一款基于覆盖引导(Coverage-guided)的模糊测试工具,它通过记录输入样本的代码覆盖率,从而调整输入样本以提高覆盖率,增加发现漏洞的概率。其工作流程大致如下: ①从源码编译程序时进行插桩,以记录代码覆盖率(Code Coverage); ②选择一些输入文件,作...

However, instead of a control-flow-based feedback mechanism (e.g., based on control-flow edge coverage), datAFLow uses a data-flow-based feedback mechanism; specifically, data flows based on def-use associations. To enable performant fuzzing, datAFLow uses a flexible and efficient memory ...

For coverage-guided fuzzing we used UnicornAFL, which is a fork of AFL++ that uses the Unicorn emulation engine to "execute" the target and employs block-edge instrumentation in a similar fashion to AFL's QEMU mode. 39 | A Security Analysis of the Data Distribution Service (...
Fuzzingdata flowcoverageThis Replicating Computational Report (RCR) describes (a) our DATAFLOW fuzzer and (b) how to replicate the results in "DATAFLOW: Toward a Data-Flow-Guided Fuzzer." Our primary artifact is the DATAFLOW fuzzer. Unlike traditional coverage-guided greybox fuzzers-which use ...
极大增加了code coverage 在JS和IE11上总共发现了19个新memory corruption bugs(16个新的vulnerabilities), 32个DOS bugs Intro P1: Fuzzing广被应用 P2: 介绍了测试用例;测试用例生成;mutation-based和generation-based;taint analysis;symbolic execution;
SQLRight: coverage-guided DBMS fuzzer, also supporting NoREC and TLP SQLsmith: random SQL query generator used for fuzzing Squirrel: coverage-guided DBMS fuzzer About Automated testing to find logic and performance bugs in database systems
Because concurrent operations can be nondeterministic and nondeterministism is a challenge for a coverage-guided fuzzing engine, fz.Chain also attempts to balance enough deterministic behavior to help the underlying fuzzing engine find interesting inputs. At execution time, the chain is represented as...
