My name is Jakob Kreuze (/​ˈdʒeɪkəb ˈkɹuz/ and /​ˈjaːkɔp ˈkʁɔʏ̯tsə/ are both acceptable pronunciations), and I'm a 25 year-old cybersecurity professional living in the Commonwealth of Virginia. Outside of work, I like to program and tinker with free software, reverse engineer things, and hunt for security vulnerabilities. In the past, I've used the traditional definition of "hacker" to describe myself. These days, the vernacular meaning is a bit more accurate.

My GPG key fingerprint is 6581 A4FC 404F 6434 AEA3 008C 45ED 4DC3 05BA DA33. I'm also on Signal as @incellebrite.666.

In general, I opt for "jakob" as a handle, settling for "0daysfordays" or "zerodaysfordays" if "jakob" was taken. Not every account with one of those handles is mine!
