by hand.

we actually read
the code.

LARP is a team of vulnerability researchers and bug hunters. We look for security bugs in software people rely on, report them to the vendor, and publish the details once they're fixed.

How we work

From bug to write-up.

(sometimes this takes a year)
  1. 01

    Read

    We start by reading the code, the binary or the spec. Most of our bugs are found at this stage.

    slow, but it works
  2. 02

    Fuzz

    We write fuzzing harnesses for the parts that looked weak while we were reading.

    lots of crashes, few real bugs
  3. 03

    Triage

    Is the crash real, can an attacker reach it, and what can they actually do with it?

    most crashes go nowhere
  4. 04

    Prove

    A small proof of concept, enough for the vendor to reproduce the bug and fix it.

    no weaponized exploits
  5. 05

    Disclose

    We report to the vendor first and give them 90 days, or longer if they need it and keep us updated.

    longest wait so far: 300 days
  6. 06

    Publish

    Once it's fixed we publish a full write-up, including the approaches that didn't work.

    so others can build on it
then back to step 1
Research

Latest write-ups.

Scope

We go after hard targets.

Browsers, kernels, hypervisors, phones and the silicon under them. We find vulnerabilities in software and hardware that millions of people run, prove they are exploitable, and stay on them with the vendor until they are fixed.

  • browser and JavaScript engine exploitation
  • Linux, Windows and hypervisor kernels
  • Android and iOS, from apps down to baseband
  • firmware, secure boot and fault injection
  • web, cloud and identity infrastructure
  • next target can't say yet
Contact

If you found something you want us to look at, or you're a vendor we contacted about a bug, email us. We reply to everything.
