Security Engineer

Karla has a varied offensive security background: she's reverse engineered train ticketing systems, written articles on TLS and SSH, and competed in the Defcon CTF finals for the last several years running. She officially works on authentication and application security at Stripe, but builds internal phishing campaigns when she has business hours to spare. She's cumulatively phished nearly half the company, has triggered many bouts of internal paranoia, and has built a reputation as being entirely untrustworthy when it comes to email.
