I make the majority of my software available to the public and make sure that it is (add-)free and secure. One of my favorite projects that I’ve worked on is Raivo (acquired), a Multi Factor Authenticator. I also publish adversary simulation (a.k.a. red teaming) exploits and tools, such as KernelMii, CMSTPLUA UAC Bypass and an exploit for AMD’s Ryzen Master Driver.

Because the software I publish is (add-)free, secure and open source, usage slowly increases. Therefore, and unfortunately for me, for certain projects cost also slowly increases. In addition to the time I spend developing, I spend money on e.g. an Apple Developer license, domain names and hosting services.

If you or your company use any of my software or exploits, please consider sponsoring me so I can continue maintaining and evolving all my projects and new ones.

Thank you for your support! 👨‍💻
