About 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. Some of the tools I have created include Cuckoo Sandbox, Viper, KrakenHardentoolsMVT, and more. I also write a personal newsletter where I reflect about security, technology and society, and occasionally publish technical blog posts.

With your support I will be able to invest more time in producing free and open source tools, and more regularly publish blog posts and newsletters.
