Peach is an SmartFuzzer capable of both mutation-based and generation-based fuzzing. Peach requires that Peach Pit files be created to define the structure, type and relationship information in the data being fuzzed. It also allows the configuration of a run, including selecting a data publisher (transporter), logging API, etc. Peach is in its third version and has been actively developed since 2004. Fuzzing is the fastest method to test for bugs and find security issues. Peach's effective hardware fuzzing will introduce students to device fuzzing fundamentals. Peach can be used to fuzz any type of data consumer, from embedded devices to servers. Researchers, corporations and governments use Peach already to find vulnerabilities in hardware. This course will cover how to use Peach to collect information from embedded devices in the event of an accident.

Solidity Fuzzing boilerplate is a repository of templates designed to make it easier to fuzze components in Solidity projects. This includes libraries. Write your tests once and use them for both Echidna's and Foundry’s fuzzing. Etheno can be used to deploy components that are incompatible Solidity versions into a Ganache instance. Use HEVM’s FFI cheat codes to generate complex fuzzing outputs or to compare the outputs with non EVM executables when doing differential fuzzing. You can publish your fuzzing experiment without worrying about licensing if you extend the shell script to include specific files. If you do not intend to use shell commands in your Solidity contracts, turn off FFI. FFI is a slow solution and should only ever be used as a temporary workaround. It can be used to test against things that are hard to implement in Solidity but already exist in other programming languages. Be sure to check the commands being executed before executing tests on a project with FFI enabled.

The hevm is a special implementation of the Ethereum Virtual Machine, which was created for the purpose of symbolic execution, unit-testing, and debugging smart contracts. It was developed by DappHub, and integrates particularly well with the DappHub toolsuite. The hevm program can run smart contracts symbolically, run unit testing, interactively debug Solidity contracts while showing their source code, or run any EVM code. Calculations can be performed by using a local test harness state or retrieved on demand from live networks via RPC calls. Run a symbolic implementation against the parameters to search for assertion violations. You can also add specific arguments to the function signature, while leaving others abstract. Hevm uses a eager approach for symbol execution, which means that it will try to explore all branches of a program first.

Tayt is the StarkNet smart contracts fuzzer. We recommend using a Python Virtual Environment.

OSS-Fuzz provides continuous fuzzing to open source software. Fuzz testing is an established technique for detecting programming errors in software. Many of these detectable mistakes, such as buffer overflow, have serious security implications. Google has discovered thousands of security flaws and stability bugs through guided in-process fuzzing of Chrome components. We now want to share this service with the open-source community. OSS-Fuzz aims at making open source software more stable and secure by combining modern fuzzing with scalable, distributive execution. ClusterFuzzLite or ClusterFuzz is available for projects that do not qualify to use OSS-Fuzz. OSS-Fuzz currently supports C/C++ code, Rust code, Go code, Python code, and Java/JVM. Other languages supported by LLVM could also work. OSS-Fuzz can fuzz both x86_64 builds and i386 versions.

Awesome Fuzzing contains a list of fuzzing materials, including books, free and paid courses, videos, tutorials, vulnerable applications, and tools to help you learn fuzzing, as well as the initial phases of exploit creation, such root cause analysis. Videos on fuzzing courses/training, videos discussing fuzzing tools, techniques, and best practices. Blogs, conference talks, tutorials, tools for fuzzing, and fuzzers to help fuzze applications that use network protocols like HTTP, SSH and SMTP. Search for exploits that have apps available to download and then reproduce the exploit using the fuzzer you choose. Set of tests to test fuzzing engines. Includes different well-known bugs. Includes a corpus of files in various formats for fuzzing multiple target targets.

Fuzzing can be a powerful way to find software bugs. The idea is simple: generate a large amount of randomly malformed data for the software to parse, and then see what happens. If the program crashes, then something is wrong. It is surprising how easy it is to find bugs in widely used software, even though fuzzing is an established strategy. Memory access errors will be the most common errors found when fuzzing C/C++ software. The core problem, while they may differ in details, is usually the same: the software reads or write to the wrong memory location. Modern Linux or BSD systems ship with a number of basic tools which display and parse files. Most of these tools, in their current state are not suitable for untrusted data. On the other hand we have powerful tools today that allow us find and analyze these bug.

LibFuzzer, a coverage-guided evolutionary fuzzing tool, is a fuzzing engine that works in the background. LibFuzzer links with the library being tested and feeds fuzzed data to the library through a specific fuzzing target function. The fuzzer tracks the code coverage and generates mutations based on the input data to maximize it. SanitizerCoverage, an instrumentation of LLVM, provides code coverage information. LibFuzzer will still be fully supported, in that important bugs are fixed. To use libFuzzer with a library, you must first implement a fuzz-target. This is a function which accepts an array and performs something interesting using the API being tested. This fuzz target is not dependent on libFuzzer, so it can be used with other fuzzing engine like AFL or Radamsa.

Honggfuzz, a software fuzzer focusing on security, is available. Supports evolutionary feedback-driven fuzzing (SW and Hardware-based) based on code cover. Honggfuzz is multi-processed and multi-threaded. You don't need to run multiple instances of your fuzzer as it can unlock all of your CPU cores. The file corpus will be automatically shared and improved among all fuzzed process. When persistent fuzzing is used, it's lightning fast. A simple/empty LLVMFuzzerTestOneInput function can be tested with up to 1mo iteration per second on a relatively modern CPU. Honggfuzz has a track record of discovering security bugs. The only vulnerability (to date) in OpenSSL that received the critical score was discovered by Honggfuzz. It will report hijacked/ignored crashes signals (intercepted by a fuzzed application and potentially hidden).

Boofuzz forks and succeeds the venerable Sulley fuzzing framework. Boofuzz is a fork of the venerable Sulley fuzzing framework. It aims to be extensible, in addition to numerous bug fixes. Boofuzz, like Sulley, incorporates all of the critical elements that make up a fuzzer, such as easy and quick data creation, instrumentation and detection of failures, target reset after failure and recording of test results. Installation is much easier and supports arbitrary communication mediums. Support for serial fuzzing and UDP broadcast. Consistent, thorough and clear recording of test data. Test result CSV export and extensible instrumentation/failure detection. Boofuzz is installed as a Python Library used to create fuzzer scripts. It is highly recommended that Boofuzz be installed in a virtual environment.

Ffuf, a web fuzzer in Go, is fast and easy to use. You can also practice Ffuf scanning against a live host using different lessons and use-cases either locally, by using the Docker Container or against the live hosted version. Virtual host discovery is provided (without DNS records). A wordlist is required to inform Ffuf of the different inputs that should be tested. You can specify one or more wordlists in the command line. If you wish to (or if you are using multiple wordlists), you can select a custom keyword. You can provide Ffuf multiple wordlists. Just remember to configure a keyword for each one. The first word from the first list is tested against the words of the second list before moving on to test the second. All combinations are tested. There are many different ways to customize your request.

Afl-unicorn allows you to fuzz any binary code that can be emulated using Unicorn Engine. Afl-unicorn can fuzz any binary that can be emulated by Unicorn Engine. Unicorn Mode implements the block-edge instrumentation normally done by AFL's QEMU Mode into Unicorn Engine. AFL will basically use block coverage data from any emulated code to drive its input. The idea revolves around a Unicorn test harness that is constructed correctly. The Unicorn-based testing harness loads the target binary code, sets the initial state and loads data mutated by AFL. The test harness emulates the binary code of the target and, if a crash or an error occurs, it will send a signal. AFL will perform all its usual tasks, but is actually fuzzing the emulated binary code. It was only tested on Ubuntu 16.04 LTS but should work with any OS that can run both AFL and Unicorn.

The Fuzzbuzz testing workflow is very similar with other CI/CD test workflows. Fuzz testing is different from other testing workflows in that it requires multiple jobs to be run simultaneously. This results in some extra steps. Fuzzbuzz provides a fuzz-testing platform. We make it easy for developers to add fuzz testing to their code, and run them within CI/CD. This helps them find critical bugs and vulnerabilities prior to production. Fuzzbuzz integrates seamlessly into your environment. It follows you from the terminal through to CI/CD. Use your own terminal, IDE, or build tool to write a fuzztest in your environment. Fuzzbuzz will run your fuzz tests automatically against your latest code changes when you push to CI/CD. You can be notified via Slack, GitHub or email when bugs are discovered. Regressions are caught as new changes and previous runs are automatically compared. Fuzzbuzz builds and instruments code as soon as changes are detected.

BFuzz uses an input-based fuzzer that accepts HTML as input, opens a new browser instance and runs multiple test cases created by domato, which is located in the recurve directory of BFuzz. BFuzz also automates the same tasks repeatedly without affecting any test cases. BFuzz asks you to choose whether to fuzz Firefox or Chrome. However, it will open Firefox using recurve, and create logs in the terminal. BFuzz allows you to open a browser and run testcases. The test cases generated by domato contain the main script. It contains additional code for DOM fuzzing.

Sulley is an extensible fuzzing engine, and fuzz testing framework. Sulley (IMHO), surpasses the capabilities of many previously published fuzzing techniques, both commercial and public domain. The framework's goal is to simplify data representation, data transmission, and instrumentation. A pure-Python, fully automated and unattended framework for fuzzing. Sulley has not only impressive data generation, but has gone a step further to include many other important aspects that a modern fuzzer should provide. Sulley keeps meticulous records and monitors the network. Sulley monitors and instruments the target's health, capable of reverting back to a known-good state using multiple methods. Sulley tracks, categorizes and detects faults. Sulley can fuzz simultaneously, increasing test speed. Sulley can automatically identify which unique sequence of test cases triggers a fault.

Radamsa generates test cases for robustness testing, or fuzzer. It is used to test a program's ability to withstand malformed or malicious inputs. It works by reading valid data files and generating different outputs. Radamsa's main selling points are that it has found a lot of bugs in important programs, is scriptable and easy to set up. Fuzzing is a technique to find unexpected behavior within programs. The idea is to simply subject the program to different inputs and observe what happens. This process has two parts: how to get the inputs, and what to do with them. Radamsa can be used to solve the first part. The second part is usually a shell script. The testers usually have an idea of what they don't want to happen and try to verify it.

APIFuzzer is a tool that reads your API description, and fuzzes each field step-by-step to determine if your application will be able to handle the fuzzed parameter. It does not require any coding. Parse API definitions from a remote URL or local file. Support for JSON and YAML files. All HTTP methods can be used. Support for fuzzing the request body, path parameter, query string and request header. Supports CI integration and relies on random mutations. Create JUnit XML format for test reports. Send a request using an alternative URL. Support HTTP basic authentication from the configuration. Save the JSON formatted report of the failed tests into the preconfigured folder.

Jazzer is an in-process, coverage-guided fuzzer developed by Code Intelligence for the JVM platform. It is based on libFuzzer and brings many of its instrumentation-powered mutation features to the JVM. Docker can be used to test Jazzer's autofuzz, which generates arguments for a Java function and reports unexpected errors and detected security issues. You can also run a standalone Jazzer binaries that starts its JVM configured for fuzzling using GitHub release archives.

FuzzDB is a dynamic application security testing tool that helps to find application security vulnerabilities. It is the most comprehensive open dictionary for fault injection patterns, predictable resources locations, and regex to match server responses. FuzzDB provides comprehensive lists of attack primitives to test fault injection. These patterns are categorized by attack and platform type where applicable. They are known to cause issues such as OS command injections, directory listings, traversals, source disclosure, file upload bypasses, authentication bypasses, XSSs, HTTP header crlfs, SQL injections, NoSQLs injections, and more. FuzzDB, for example, catalogs 56 patterns which can be interpreted as null bytes and contains lists of frequently used methods and name/value pairs that trigger the debug mode.

ClusterFuzz provides a scalable fuzzing system that can be used to find security and stability issues within software. Google uses ClusterFuzz as the fuzzing engine for OSS Fuzz and to fuzz all Google Products. ClusterFuzz offers many features that allow fuzzing to be seamlessly integrated into the software development process. Fully automatic bug filing and triage for different issue trackers. Supports multiple coverages-guided fuzzing engines to achieve optimal results (with ensemble fuzzing and fuzzing strategy). Statistics to analyze fuzzer performance and crash rates. Web interface for managing and viewing crashes. Support for multiple authentication providers using Firebase. Support for black-box fuzzing, test case minimization and regression finding using bisection.

Go-fuzz provides coverage-guided fuzzing for testing Go packages. Fuzzing is most useful for packages that parse binary and text inputs. It is also useful to harden systems that parse inputs that are potentially malicious (anything that is accepted over a LAN). Go Modules are now supported by go-fuzz. Please file an issue if you encounter a module problem. Data is a randomly generated input by go-fuzz. Note that it is usually invalid. The function must return 0 if no input should be added to the corpus, but the fuzzer must increase the priority. The fuzz function has to be in a package go-fuzz is able to import. This means that the code you wish to test cannot be in package main. However, fuzzing internal packages can be done.
