Automates reconnaissance for bug bounty and penetration testing target
BigBountyRecon is an open source reconnaissance tool designed to assist security researchers, penetration testers, and bug bounty hunters during the early stages of security assessments.

Its main goal is to accelerate the information-gathering phase, which is often considered one of the most important steps in penetration testing and bug hunting. By quickly identifying potential information leaks and publicly exposed resources, the tool helps users gain an initial understanding of the target’s security posture. BigBountyRecon allows researchers to perform multiple reconnaissance checks without having to manually remember or craft complex search queries. It aggregates results from dozens of discovery techniques so analysts can identify possible entry points and weak configurations. -

AWS Encryption SDK for Dafny
AWS Encryption SDK for Dafny
To build, the AWS Encryption SDK requires the most up-to-date version of dafny on your PATH. In addition, this project uses the parallel verification tasks provided by the dafny.msbuild MSBuild plugin, and thus requires dotnet 3.0. The tests currently require native implementations of cryptographic primitives and other methods, so they can only be run when embedding this library into one of the compilation target languages supported by Dafny. This repo uses Duvet to directly document the specification alongside this implementation. Refer to the specification for how to install duvet in order to generate reports. By default duvet_report will extract the spec only if it cannot find the compliance directory in the specification repo, but will re-use a previous extraction if it exists. -
