WPA3 Wi-Fi protocol aims to improve security in 2018

The Wi-Fi Alliance introduced the next generation of Wi-Fi Protected Access — WPA3 — which aims to improve password security as well as security for IoT devices.

The industry will begin rolling out the WPA3 Wi-Fi protocol in products in 2018 and replace WPA2, meaning vendors will have to follow the security standard in order to carry the “Wi-Fi Certified” branding.

In an official announcement from CES in Las Vegas, the Wi-Fi Alliance noted that the WPA3 Wi-Fi protocol will include “four new capabilities for personal and enterprise Wi-Fi networks.”

“Two of the features will deliver robust protections even when users choose passwords that fall short of typical complexity recommendations, and will simplify the process of configuring security for devices that have limited or no display interface. Another feature will strengthen user privacy in open networks through individualized data encryption,” the Wi-Fi Alliance wrote. “Finally, a 192-bit security suite, aligned with the Commercial National Security Algorithm (CNSA) Suite from the Committee on National Security Systems, will further protect Wi-Fi networks with higher security requirements such as government, defense, and industrial.”

According to Mathy Vanhoef, a network security and applied cryptography post-doctoral candidate and one of the researchers behind the WPA2 KRACK vulnerability which took advantage of the WPA2 four-way handshake network connection process to produce a man-in-the-middle exploit. WPA3 implements a more secure handshake that should help prevent brute force password attacks.

Marc Bevand, former security engineer at Google, described in a Hacker News forum post how this type of password authenticated key exchange (PAKE) can prevent attacks online and off.

“[Offline, an attacker] can try to decrypt the packet with candidate passwords, but he does not know when he guesses the right one, because a successful decryption will reveal [values that] are indistinguishable from random data. And even if he guessed right, he would obtain [public keys], but would not be able to decrypt any further communications as the use of Diffie-Hellman makes it impossible to calculate the encryption key,” Bevand wrote. “[Online,] if he actively [man-in-the-middles] the connection and pretends to be the legitimate server, he can send his own [key and password] to the client using one guessed candidate password. If he guessed wrong … each authentication attempt gives him only one chance to test one password. If, out of frustration, the client tries to retype the password and re-auth three times, then the attacker can at most try to guess three candidate passwords. He can’t brute force many passwords.”

Additionally, experts noted that the WPA3 Wi-Fi protocol improvements to “configuring security for devices that have limited or no display interface” could help improve security on IoT devices, but not all experts, like Tom Van de Wiele, principal cyber security consultant and red-teamer at F-Secure, were optimistic about the possibility.

Android KRACK flaw patched in latest security update

Google’s latest security update included the patch for the Android KRACK Wi-Fi flaw, but it is unclear when users will see the fix rolled out to devices.

When researchers first disclosed the KRACK vulnerability, they made it clear that the attack was “exceptionally devastating against Linux and Android 6.0 or higher” because those systems could be “tricked into (re)installing an all-zero encryption key.”

The November security update from Google included the patch for the Android KRACK flaw and fixed the issue for versions 5.0.2 through 8.0 of the mobile OS. However, users have already seen issues with the rollout.

The Android KRACK patch was part of the security patch level 2017-11-06 released by Google, but the November release was also split into patch levels 2017-11-01 and 2017-11-05. Google’s own Pixel and Nexus devices were first to receive a rollout, but some users reported getting the 2017-11-05 patch level, which meant the Android KRACK flaw was not fixed.

Users on Twitter expressed confusion about Google pushing the patch level that did not remediate the KRACK vulnerability, and the CopperheadOS Twitter account provided a possible explanation.

“They have the wpa_supplicant patches in the release for Pixels today marked EMR but they appear to have reverted the patch level back to 2017-11-05 so there’s probably something missing outside wpa_supplicant,” CopperheadOS wrote on Twitter. “It’s only in the branch for 2nd generation Pixels so it’s not really patched in AOSP when none of the branches has the patches without them being reverted. For most devices, they’ll only get it with 2017-12-01.”

Android KRACK around the ecosystem

Normally, users have to wait until Google adds a patch to the Android Open Source Project repository before hardware manufacturers can begin work to push the fix, but with the Android KRACK flaw manufacturers appear to have begun the work to fix the issue before Google.

Manu Kumar Jain, vice president and managing director of Xiaomi India, announced its patch three days before Google.

Samsung also confirmed its November 2017 security update will include the Android KRACK patch, but the rollout of the update had not yet begun at the time of this post.  

The original researchers who discovered KRACK were initially praised for disclosing the issue beforehand to allow major manufacturers time to create patches, but it is unclear when Google was informed of the issue.
