WPA will be the standard for most networks. WPA runs on older systems that haven’t been updated or maintained. WPA isn’t as easy to hack into as WEP. We will be discussing one method to hack into a WPA network and the potential pitfalls.

WPS Pin Attack

WiFi Protected Setup is a feature that many WiFi routers and access points have but are often forgotten about. This convenient feature allows you to set up a client device against a WiFi network using a button on both access points and client devices (the client-side “button”, which is often found in software), simultaneously. The devices exchange information and then create a secure WPA connection.

This is an extremely clever feature. This allows users who are less tech-savvy to quickly establish a secure connection between their devices. It also requires physical access to the hardware so it is not as secure as you might think.

Reaver, a tool that can brute-force WPA handshaking remotely, has been created.

Although newer devices have been developed to protect against this attack, the Reaver WPS exploit is still useful on many networks.

53 percent of security professionals don’t know the number of devices connected to their wireless network.

To highlight the dangers posed by rogue access points, we surveyed more than 200 security professionals. To help protect your wireless network, download the 2020 Internet of Evil Things Report.

Finding a Network

You’ll be familiar with the command to put the hardware in monitor mode if you have read the tutorial on hacking into WEP networks.

You could also use airodump. ng to search for networks. However, Reaver has its tool to find vulnerable WPS implementations. Run the following command to start it:

This is the output:

These two networks are at least theoretically vulnerable to the WPS brute-force attack Reaver uses. The “WPS Locked” column is a rough indicator. However, it will show that unlocked APs are more susceptible to brute-forcing. Although you can still launch an attack on a WPS-locked network, your chances of success are not high.

Reaver Launched

After you have identified the network that you want to attack, Reaver can be used. Only the local interface is required for basic commands.

To be specificated channel and ESSID This is how the command to launch Reaver against “Linksys”, the network would look:

The only thing that may not be obvious in the command above is “-vv”. This allows for verbose output, which is very helpful when trying to determine how Reaper is progressing (or not).

After you have started Reaver, you will start to see this output:

This output indicates that WPS pins have been successfully tested against the target (here 12345670, 00005678 are being tested), while Reaver is still operating as normal.

Advanced Options

The attack proceeds as planned if the basic command works. In reality, however, different manufacturers have attempted to implement protections against WPS pins Reaver attacks. Additional options may be necessary to move the attack forward.

The following example shows how to add a few switches to Reaver’s ability to work on pickier devices.

While the core command isn’t changing, the additional switches change how Reaver behaves.

-L

Ignore locked WPS state.

-N

If errors are found, don’t send NACK packages.

-d 15

Between PIN attempts, delay 15 seconds

-T

The timeout duration should be set to half a second

-r 3:15

After three attempts, you can finally fall asleep for 15 seconds

Although this is not an exhaustive list, it will give you an idea of the types of Reaver options that might be available.

Attack Duration

Reaver can take quite a while to complete even under ideal conditions. Although there is some chance that brute-forcing might find the PIN quickly, it will take Reaver many hours to make any dent in the pool of possible PINs.

Reaver automatically keeps a log of the progress so that you can stop an attack and restart it whenever it suits you. Spending a few hours a day running Reaver against the same network should uncover its PIN and through that the WPA passphrase…eventually.
