$22k awarded to SBFT ‘23 fuzzing competitors winners


Google’s Open Supply Safety Staff lately sponsored a fuzzing competitors as a part of ISCE’s Search-Based mostly and Fuzz Testing (SBFT) Workshop. Our purpose was to encourage the event of recent fuzzing methods, which may result in the invention of software program vulnerabilities and finally a safer open supply ecosystem. 

The rivals’ fuzzers have been judged on code protection and their potential to find bugs: 

Rivals have been evaluated utilizing FuzzBench, Google’s open supply platform for testing and evaluating fuzzers. The platform boasts a variety of actual world benchmarks and vulnerabilities, permitting researchers to check their fuzzers in an genuine setting. We hope the outcomes of the SBFT fuzzing competitors will result in extra environment friendly fuzzers and ultimately newly found vulnerabilities. 

Eight groups submitted fuzzers to the ultimate competitors and an extra 4 business fuzzers (AFL++, libFuzzer, Honggfuzz, and AFL) have been included as controls to signify present observe. 

HasteFuzz, is a modification of the broadly used AFL++ fuzzer. HasteFuzz filters out probably duplicate inputs to extend effectivity, making it in a position to cowl extra code within the 23-hour check window as a result of it’s not more likely to be retracing its steps. AFL++ is already a powerful fuzzer—it had the most effective code protection of the business fuzzers examined on this competitors—and HasteFuzz’s filtering took it to the following degree.

PASTIS makes use of a number of fuzzing engines that may independently cowl completely different program areas, permitting PASTIS to seek out bugs shortly. AFLrustrust rewrites AFL++ on high of LibAFL, which is a library of options that lets you customise current fuzzers. AFLrustrust successfully prunes redundant check instances, enhancing its bug discovering effectivity. Each PASTIS and AFLrustrust discovered 8 out of 15 attainable bugs, with every fuzzer lacking just one bug found by others. They each outperformed the business fuzzers, which discovered 7 or fewer bugs below the identical constraints.

Extra rivals, resembling AFL+++ and AFLSmart++, additionally confirmed enhancements over the business controls, a consequence we had hoped for with the competitors.

The innovation and enchancment proven by means of the SBFT fuzzing competitors is one instance of why now we have invested within the FuzzBench mission. Since its launch in 2020, FuzzBench has considerably contributed to high-quality fuzzing analysis, conducting over 900 experiments and mentioned in additional than 100 tutorial papers. FuzzBench was supplied as a useful resource for the SBFT competitors, however additionally it is obtainable to researchers each day as a service. In case you are taken with testing your fuzzers on FuzzBench, please see our information to including your fuzzer.

FuzzBench is in energetic growth. We’d welcome suggestions from any present or potential FuzzBench customers, your responses to this survey can assist us plan the way forward for FuzzBench.

The Google Open Supply Safety Staff want to thank the ISCE convention and the SBFT workshop for internet hosting the fuzzing competitors. We additionally need to thank every participant for his or her exhausting work. Collectively, we proceed to push the boundaries of software program safety and create a safer, extra sturdy open supply ecosystem.
