Go fuzzing was missing half the toolkit. We forked the toolchain to fix it.
Summary
Trail of Bits reports on Gosentry, a fuzzing-oriented fork of the Go toolchain that integrates LibAFL and supports structure-aware and grammar-based fuzzing. The project aims to close gaps in Go fuzzing by detecting more bug classes, improving inputs, and providing campaign coverage reports, with practical guidance for leveraging gosentry alongside existing Go fuzzing workflows.
