hcxdumptool -o test.pcapng -i wlp39s0f3u4u5 -enable_status Step 1 - An attacker can use a tool, like hcxdumptool (v4.2.0 or higher), to request the PMKID from the targeted access point and dump the received frame to a file. Robust Security Network is a protocol for establishing secure communications over an 802.11 wireless network and has PMKID, the key needed to establish a connection between a client and an access point, as one of its capabilities. Instead, it is performed on the RSN IE (Robust Security Network Information Element) using a single EAPOL (Extensible Authentication Protocol over LAN) frame after requesting it from the access point.Īlso Read: How to Hack WPA2 WiFi Protocol Using KRACK Attack Whereas, the new attack no longer requires another user to be on the target network to capture credentials. According to the researcher, the previously known WiFi hacking methods require attackers to wait for someone to log into a network and capture a full 4-way authentication handshake of EAPOL, which is a network port authentication protocol.
