If a wireless network can withstand a GPU-assisted dictionary attack with mutations during a given timeframe, one can consider the network to be secure.
Every year, millions of user accounts are compromised, and millions of passwords are leaked. We strongly recommend obtaining the list of the most commonly used passwords such as the Top 10, passwords or Top 10 million passwords, and run a simple, straightforward attack through the dictionary of leaked passwords. The dictionaries of the most common passwords can be obtained from GitHub. Wi-Fi passwords frequently contain one or more words in natural language. You can often recover such passwords by running a dictionary attack.
A dictionary attack against a Wi-Fi password requires one or several dictionaries; a dictionary of English words is a good starting point, but dictionaries of local languages should not be forgotten. Sometimes, the among of modifications is just enough to pass the enforced security policy. To help attacks target passwords selected by average users, we developed an automated mutations engine. The mutations engine automatically alters dictionary words to mimic common patterns.
You can easily apply mutations to dictionary words. More time is required when more mutations or higher mutation level are selected.
Elcomsoft Wireless Security Auditor offers a dozen different mutations. Enabling all of these mutations at the same time enormously expands the number of passwords to try, making it difficult or impossible to reach the end of the list in reasonable time. For this reason, we strongly recommend using a reasonable number of mutations and choosing only those mutations that are likely to be used in a given case.
Without Perfect Forward Secrecy they could read the saved transmissions from Monday. With it, they can not. Here again, a sufficiently long WPA2 password offers protection from brute force attacks. However, if someone gives out the Wi-Fi password, then Forward Secrecy is nice to have, assuming you are important enough for bad guys to hang out near your home and record all the Wi-Fi traffic.
But, the millions of existing devices that depend on WPS are not going to vanish in an instant. So, WPS still needs to be supported. As with everything nowadays, it depends on a smartphone. I don't know how it works when the router is creating multiple Wi-Fi networks. I would not trust this for quite a while. New software protocols from the Wi-Fi Alliance are best avoided. Their history is one of very poor design.
WPA3 itself, is their fourth crack at over-the-air encryption. Easy Connect may turn out to be very secure, but to me, the jury will be out for a couple years. Improvement 4: Encryption without a password. This feature is called Wi-Fi Enhanced Open and it adds over-the-air encryption to networks that do not require a password. But there are so few "open" networks not password needed , that I don't see this as a big deal.
The organization is an industry disgrace. And, it seems that with the WPA3 standard, they are maintaining their miserable reputation.
To be clear, these are not coding flaws, they are poor design. Depending on how you count there are at least five design mistakes. Their website documenting the flaws is Dragonblood. No one has yet kicked the tires on the protocol and it is not clear when devices will even support it. The biggest flaw with WPA2, is that bad guys can make off-line brute force guesses of the Wi-Fi password. Billions and billions of guesses every second.
WPA3 should eliminate this flaw. That said, a sufficiently long WPA2 password over 15? Here is an overview of the improvements. The improvements are scheduled in two phases, the first is known as WPA2 enhancements and it is expected to be released before the end of The second phase is full blown WPA3.
WPA3 compliant products are expected to start appearing before the end of The WPA2 enhancements mandate the use of Protected Management Frames PMF , more stringent validation of vendor security implementations, and improved consistency in network security configuration.
IEEE Without it, management frames are transmitted unencrypted and their integrity is not verified. PMF ensures integrity of network management traffic, provides protection against eavesdropping, replay and the forging of management action frames. Many wireless vulnerabilities are the result of poor implementation or misconfiguration. WPA2 enhancements will require additional tests on Wi-Fi certified devices to ensure both the use of best practices and that the products yield expected behaviors.

The dup will be along in a couple of hours for those that missed it the first time too. Quote from: Leiothrix on August 08, , pm. Halcyon Global Moderator Posts: Country:. Quote from: BravoV on August 08, , pm. If you have a single AP network it should not be enabled anyway.
