Run next tool called hcxpcaptool to convert the captured data from pcapng format to a hash format accepted by hashcat using following code. hcxdumptool -o test.pcapng -i wlp39s0f3u4u5 –enable_status In order to make use of this new attack you need the following tools:įirst Run hcxdumptool to gain the PMKID from the AP and dump the file in PCAP format using following code. “Here we can see that the PMKID has been captured is computed by using HMAC-SHA1 where the key is the PMK and the data part is the concatenation of a fixed string label “PMK Name”, the access point’s MAC address and the station’s MAC address.” Pairwise Master Key ID (PMKID) can be captured from RSN IE whenever the user tries to authenticate with the router. Robust Security Network Information Element (RSN IE) is an optional one in 802.11 management frames and its working in a single EAPOL frame. How Does this WPA/WPA2 WiFi Password Attack Works: Researcher finds this attack to compromise the WPA/WPA2 password without performing EAPOL 4-way handshake.Īccording to Steube who is the developer of Hashcat password cracking tool, The new attack is performed on the RSN IE (Robust Security Network Information Element) of a single EAPOL frame.Īlso, this attack work Against all type of 802.11i/p/q/r networks with roaming functions enabled and it’s unclear how many vendors and how many routers this technique will work. New WP3 Security Standard released by Wi-Fi Alliance that provides Next-generation Wi-Fi Security with new capabilities to enhance both personal and enterprise networks and the new WP3 security standard that is a successor of WPA2.
This Method found during the attack against the recently released WPA3 security standard which is extremely harder to crack since its used Simultaneous Authentication of Equals (SAE), a modern key establishment protocol. The new method to crack WPA/WPA2 enabled WiFi networks that allow attackers to access Pre-shared Key hash that used to crack Passwords used by targeted victims.
