Researchers from the University of Leuven (@vanhoefm and team) have discovered flaws in WPA2 implementation in clients and APs. These flaws create vulnerabilities for replay and decryption attacks on packets transferred over WiFi links. They have named them KRACKs (Key Reinstallation AttaCKs). Both 802.1x (EAP) and PSK (password) based networks are affected. These vulnerabilities have been cataloged under 10 CVEs. In the series of videos below, I explain these CVEs in detail with Vivek Ramachandran, Founder and CEO of Pentester Academy.

Without Classroom WiFi, STE(A)M Doesn’t Exist
Posted by Rick Wilmer on Jun 27, 2016

Since the introduction of the STEM (Science, Technology, Engineering and Math) and STE(A)M (Science, Technology, Engineering, Arts and Math) movements about 10 years ago, there has been a focus on making sure that our students in the United States receive a great education to stay competitive in a worldwide market.

For me, the STE(A)M movement has a deeply personal connection. My background is in engineering and technology, my degree from Cal Berkeley is in Chemistry, which lead me to a 25-plus year career in technology. My education and career path have been very “left brain” (i.e. logical, analytical) focused. What I discovered over the years is that my “right brain” (intuitive, thoughtful, creative) not only needs a release but that giving that part of my mind regular exercise makes me better at my job.
