Jazzer – Modern fuzz testing for the JVM (open-sourced)
- m42smith 6y agoProbably biased because I know the authors but still, this is really cool! Anybody using Java should take a look at this!
- fhenneke 6y agoI'm one of the engineers behind Jazzer and happy to answer any questions about it. We also have a blogpost that talks about the most interesting technical aspects of Jazzer: https://blog.code-intelligence.com/engineering-jazzer https://blog.code-intelligence.com/engineering-jazzer
- sufficient 6y agoGreat work Fabian! Nice to see this work becoming open source. I am pretty new to fuzzing, please correct me if I am wrong: Since Jazzer fuzzes a Java application at runtime, can it be in principle also be used to fuzz a Java app without having it's source code?
- fhenneke 6y agoYes, that is exactly how it works, there is nothing that would require source code access. If you have a Java app packaged as app.jar, all you need to do is write a fuzz target (with the fuzzerTestOneInput function) and package it into e.g. target.jar. Then you can run jazzer with --cp=app.jar:target.jar --target_class=fuzz.target.Class
- sapiens94 6y agoI love it! Cool to see this happening.
