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.
