Become a sponsor to Nex

My name is Claudio Guarnieri, otherwise known online as Nex. I'm a security researcher, free software developer, human rights advocate and spare time artist. You can find a more comprehensive bio here.

I have founded and led Amnesty International's Security Lab. Over the last decade I primarily worked on researching threats to human rights defenders and helping them stay safe online. Additionally, I develop free software and maintain free services, for individuals at risk as well as fellow security researchers. I also write a personal newsletter where I reflect about security, technology and society.

With your support I will be able to invest more time in producing free and open source content.

Following are some of the projects I have created:

  • Cuckoo Sandbox
    The most popular open source malware analysis sandbox, used by thousands of researchers and organizations around the world.
  • MVT
    MVT is a collection of utilities to simplify the process of gathering forensic evidence from mobile devices, useful to identify potential traces of compromise. Released along with the Pegasus Project.
  • pcqf
    pcqf (PC Quick Forensics) is a little utility to automate the collection of useful forensic artifacts from a Windows computer. It is intended for human rights researchers and technical support working with activists and journalists in order to quickly collect potential evidence of compromise.
  • androidqf
    androidqf (Android Quick Forensics) is a cross-platform utility to automate the process of extracting forensic evidence from Android device. It is intended to be simply used by non-tech savvy users as well to facilitate conducting remote forensics.
  • Viper Framework
    Viper is a framework for binary analysis, clustering, and management. It allows you to quickly triage malicious samples, and extract static information from supported file formats.
  • PhishDetect
    PhishDetect is a project I started and I am currently developing. It's a collection of tools and services to help activists and journalists at risk identify, report and block malicious attacks.
  • Hardentools
    Hardentools is a tool I created to simplify the process of hardening certain settings in Windows to reduce attack surface for at-risk users.
  • Kraken
    Kraken is an advanced Yara scanner. It allows to scan the filesystem, running processes, and autorun entries on Windows, Linux and Mac computers. It is provided with a backend the Kraken agent can report results to.

This would help me sustain server costs for free services and websites I run, pay for domain names, etc. ❤️
