SUMMARY:Hopper - Distributed Fuzzer : Luciano Remes : Wade Cappa
DESCRIPTION:Presenter: Luciano Remes\nCo-Presenter: Wade Cappa\nLocation: W

 curity Research\nProject: https://github.com/Cybergenik/hopper\n\nAbstract
 :\nHopper is a Coverage-Guided Greybox Distributed Fuzzer\, inspired by AF
 L++\, and written in Golang. Like other fuzzers\, Hopper operates as a sta
 ndard command-line interface tool\, allowing you to run fuzz campaigns to 
 find vulnerabilities and exploits in software. Hopper's mutation algorithm
 \, energy assigning strategy\, and out-of-process coverage gathering\, are
  all inspired by AFL++\, the current state of the art fuzzer. However\, Ho
 pper's distributed strategy differs substantially than AFL++ in an attempt
  to define a new distributed fuzzing paradigm. AFL++ and LibFuzzer have cl
 ear scaling limitations in larger environments\, notably the AFL++’s rud
 imentary multi-machine mode. As an early prototype\, Hopper addresses thes
 e limitations by implementing a deduplicating communication schema that es
 tablishes a consistency invariant\, minimizing repeated work done by fuzzi
 ng nodes. Hopper is a standalone\, new piece of software developed from sc
 ratch in the spirit of exploration\, this is not yet another python plugin
 /extension for AFL++. Hopper is currently available on GitHub\, including 
 containerized runnable campaign demos. Tooling and observability are first
  class features\, in the form of a TUI to monitor fuzzing campaigns\, usag
 e docs\, and quick-start scripts for orchestrating fuzz campaigns.\n\nBios
 :\n* Presenter:\nLuciano Remes received a B.S. in Computer Science from th
 e University of Utah\,\nwhere he did 2 years of grant-funded Systems resea
 rch under the FLUX Research\nGroup\, finally working on his Thesis Hopper:
  Distributed Fuzzer. During this\ntime\, he also interned at AWS EC2 and G
 oldman Sachs SPARC infrastructure teams\,\nas well as a few startups inclu
 ding Blerp and Basecamp. Currently\, he's a\nSoftware Engineer at Palantir
  Technologies building distributed network\ninfrastructure.\n* Co-Presente
 r:\nWade Cappa recently graduated from Washington State University with a 
 B.S in\nComputer Science and is now working at Palantir Technologies as a 
 Software\nEngineer on distributed data systems. He previously worked at Mi
 crosoft in the\nSemantic Machines department\, creating a dynamically link
 ed debugging utility\nfor an internal use tooling language. In his freetim
 e he is working with a\nhigh-performance-computing research group on a cut
 ting edge distributed\nstrategy for approximating submodular monotonic opt
 imizations.
