• 2018 Pwnie Award for Best Cryptographic Attack.

I am developing the following Open Source security tools:

• badkeys - detecting cryptographic public keys with known vulnerabilities.
• snallygaster - finding file leaks on websites.
• freewvs - scans web roots for known vulnerable web applications.
