Author(s)
Michael Fahr Jr., Hunter Kippen, Andrew Kwong, Thinh Dang, Jacob Lichtinger, Dana Dachman-Soled, Daniel Genkin, Alexander Nelson, Ray Perlner, Arkady Yerukhimovich, Daniel Apon
In this work, we recover the private key material of the FrodoKEM key exchange mechanism as submitted to the NIST PQC standardization process. The new mechanism that allows for this is a Rowhammer-assisted poisoning of the FrodoKEM KeyGen process. That is

Can You Spot a Phish

October 19, 2022
Author(s)
Shanee Dawkins, Jody Jacobs
This talk will cover findings from over 4 years of NIST phishing training data, highlighting user context as the key to phishing susceptibility. We will discuss the NIST Phish Scale, our research on why users click, and how it can help users spot a phish.
