💥 Fuzzing found a crash—but how do we debug it?

We present DiffMin, a technique that makes crashing inputs closer to passing ones while keeping the crash. This helps localize and diagnose crashes more precisely. Just accepted to FSE’25 Posters 🎉

Refining Fuzzed Crashing Inputs for Better Fault Diagnosis
We present DiffMin, a technique that refines a fuzzed crashing input to gain greater similarities to given passing inputs to help developers analyze the crashing input to identify the failure-inducing...

A new look! We have created a new version of The Fuzzing Book, based on #JupyterBook, bringing

* easier navigation
* dark mode
* search
* mobile layout

and lots of other features. Check it out at www.fuzzingbook.org/beta/html/in...

Should we continue with this new look? Comments are welcome!

Can we foresee the unseen in software testing?

I’ll share how statistical magic helps us quantify residual risk and make testing results more accountable and reliable✨Thanks for the invite! 🙏

🎉 Excited to share that my 1st paper at @iclr-conf.bsky.social has been accepted! Big thanks to my awesome colleague @mboehme.bsky.social and the fantastic SoftSec group #MPI. Marcel has shared a great post with a brief explanation of our work—check it out! 🚀
I’ll share a public version soon!
Just got our first ICLR paper accepted! 🥳🥳

It shines light on a beautiful statistical riddle! Suppose, you train a classifier. How representative was the training data? What is the proportion of the *unknown* population of classifier inputs with classes *not* in the training data?
