Scouting report
Demonstrated SSLstrip and a run of attacks that exposed how fragile the certificate authority system really was. Then built Signal and the double-ratchet protocol behind it, which WhatsApp and others adopted — quietly putting end-to-end encryption in front of billions of people.
Curator’s note
Attacked the transport layer, then rewrote it. The set’s highest-leverage card.
