It … utilizes one problem of PMKID caching: the WLAN password is actually transported over the air in a hash it’s attackable using brute-force attacks. Sounds too simple what’s the catch? Johannes Luther agrees, calling it Yet Another WPA Attack: This attack is so obvious, I cannot believe nobody found it earlier (including me). … we can attack this hash as any other hash type. Since the PMK is the same as in a regular EAPOL 4-way handshake this is an ideal attacking vector. The PMKID 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. No more eventual retransmissions of EAPOL frames. No more waiting for a complete 4-way handshake. … The main advantages of this attack are as follows:Īttacker directly communicates with the AP (aka 'client-less' attack).

We think it will work against … most modern routers. WPA3 will be much harder to attack because of its modern key establishment protocol called 'Simultaneous Authentication of Equals' (SAE). Hashcat creator Jens Steube describes his New attack on WPA/WPA2 using PMKID: This attack was discovered accidentally while looking for new ways to attack the new WPA3 security standard. … The average time it takes to accomplish one’s nefarious purpose is around 10 minutes. The new strategy allows an attacker to instead lift the … Pairwise Master Key Identifier (PMKID) … directly from the router, without waiting. … Hackers have compromised the WPA/WPA2 encryption protocols in the past, but it’s a … time-consuming process that requires a man-in-the-middle approach. Why isn’t there more love in the world? Here’s Tara Seals with a kiss: Wi-Fi just became a little less safe. … Previously, an attacker would need to wait for someone to log into a network capture the four-way handshake. Jens Steube, creator of the open-source software, said the new technique … would potentially allow someone to get all the information they need to brute-force decrypt a Wi-Fi password. technique specifically works against … Wi-Fi networks with PMKID-based roaming features enabled … using IEEE 802.11i/p/r protocols.

What’s the craic? Shaun Nichols- Cracking the passwords of some WPA2 Wi-Fi networks just got easier: The folks behind the password-cracking tool Hashcat claim they've found a new way to crack some wireless network passwords in far less time … by snooping on a single data packet going over the air. Not to mention: What if Hitler didn’ t invade Russia?… PMKID vuln in PSK nets Your humble blogwatcher curated these bloggy bits for your entertainment. In this week’s Security Blogwatch, we’re in your GPUs, hashing your cats. So a hacker can capture a ton of WPA2 traffic, take it away, and decrypt it offline. It’s now much easier to grab the hashed key. Wi-Fi encryption developed yet another chink in its armor this week.
