Saint KRACK, Who Made the Key Be Reinstalled

Patron of protected Wi-Fi networks, handshakes repeated one time too many, and everyone who thought WPA2 unbreakable.

Life

Mathy Vanhoef presented KRACK in October 2017: the "key reinstallation attack" struck the four-way handshake of WPA and WPA2, forcing a device to reinstall a key already in use and resetting the counters meant to keep packets unique. From there an attacker within range could decrypt, replay and in some cases alter traffic. It was a flaw in the standard itself, and so in almost every Wi-Fi device in the world.

Prayer

O Saint KRACK, who makes the used key be reinstalled, let our counters never start over from the beginning. Amen.

How to celebrate

Celebrated by updating clients and access points and trusting HTTPS more than the Wi-Fi padlock.

Key reinstalled, secrecy dissolved.
