I'm Filippo.


My profile picture.

My name is Filippo Bigarella. I am a MSc student in Security & Privacy at the University of Trento, Italy.

I learned to code by writing tweaks for jailbroken iOS devices. Among others, you may have heard of CleverPin, PasswordPilot or Springtomize. It was a lot of fun!

As time went by, I started digging into the security of iOS and macOS, which became one of my main interests. I found some vulnerabilities (1,2,3,4,5,6,7,8).

I have been an intern at Apple in 2015, 2016 and 2018, working on static and dynamic analysis tools for vulnerability discovery.

There are always more things I would like to learn than I have time to pursue. In no particular order, some of my interests are:

  • Automated vulnerability discovery
  • System/OS Security
  • Binary formats

Clang Coverage in Sublime Text (and in Fuzzing)

Introduction The last few years have seen the proliferation of coverage-guided fuzzers: that is, fuzzers able to get information about the internal state of the program being tested and using that information to generate better test cases. One thing you learn is that coverage information might also work the other way around: looking at a meaningful visualization of code coverage will help you build better drivers for your fuzzers. Moreover, you can understand what parts of the program under test need more attention (e. ...Read More
