WEP stands for Wired Equivalent Privacy. And this is the first wifi security, which was. Michael is a security enthusiast who has been in the pen testing space for over a decade. In his spare time he likes to stay abreast of new happenings in this ever-changing industry through reading and writing cyber security related articles.

Update The default WPA2-PSK passphrase used in some Belkin routers simply replaces a character of the device’s MAC address with another hecxadecimal character, according to security blogger Jakob Lell.

Lell describes the situation as follows:

Each of the eight characters of the default passphrase are created by substituting a corresponding hex-digit of the WAN MAC address using a static substitution table. Since the WAN MAC address is the WLAN MAC address + one or two (depending on the model), a wireless attacker can easily guess the wan mac address of the device and thus calculate the default WPA2 passphrase.

Guys in this tutorial I am going to show you how to get password of saved wifi ii like my video stay updated by subscribing this. Recently posted Second Method to hack wifi password. How to Hack Wifi Password – First Method: First of all you need to scan for available wireless networks. You can use“NetStumbler” or “Kismet” for Windows and Linux and KisMacfor Mac. It’ll also show how the Wi-fi network is encrypted. The two most common encryption techniques are. Identify the target modem and the modem password Break We have to do first after you open the desktop, open terminal. For this click on the terminal icon on the side of the menu. Opens the terminal to the computer after the connection of the wireless adapter and the connection that we attach the name of the interface to check. Hack Wi-Fi in MAC PC; This step, WiFi Cards will be shown up. Enter the order number of the Cards (in the case you have more than one WiFi cards). Enter 1to get the available WiFi networks list.The list of WiFi networks around you will appear, press Ctrl+ C to stop scanning more. Choose the targeted WiFi by entering the order number. If someone were trying to hack your WiFi password, there is a good chance you would never be aware that an attempt was made. An unscrupulous individual who understood how to hack WiFi passwords could be using your network to enact their own Internet access or gain entry into your network and electronic resources.

In either case, that’s problematic because it is possible to interrogate WiFi routers in order to learn their MAC address. Some models even advertise the address on the case of the device!

Lell’s revelation, which he says makes it possible to deduce passwords by drawing up a simple substitution table, means all an attacker needs to do to compromise a device is learn its MAC address and then spend a few minutes converting it into Hex.

Lell’s post on the topic suggests Belkin’s Surf N150 Model F7D1301v1, N900 Model F9K1104v1 and N450 Model F9K1105V2 are all susceptible to the attack.

He also writes that other routers may have the same issue, with only the substitution table differing.

“It is likely that other Belkin devices are affected as well,” Lell’s post says, adding that he has tried to engage the company on the issue since January 2012, without success. “Unfortunately, Belkin has not yet cooperated with us to fix the vulnerability and/or confirm a list of other affected devices,” he says.

The good news is that users need only change the password to make the poorly-coded default codes irrelevant. And we all know users are always diligent about that kind of chore and would never leave a system in an insecure state.

Belkin has responded to The Register's inquiries, saying 'We have been made aware of the work recently published by two researchers at the Technische Universität Berlin regarding the default security configuration of Belkin routers, and appreciate their contribution to improved Wi-Fi security.'

The responses goes on to say the company is 'reviewing the details of the published research to understand its full implications' and will fix the problem if necessary, 'so as to ensure our users continue to benefit from the maximum level of security possible while also guaranteeing interoperability and ease of use.” ®

Every new hacker loves to Google the words “How to hack WiFi passwords?” So i thought why not make a blog post on it.

PS Every professional hacker was a script kiddie at some point

Before we start lets look at some terminology.

BSSID- It is the MAC addrses of a device
ESSID- It is the name of a device.
AP- Access Point, example a router.

There are a few types of WiFi encryption:

  • WEP (Wired Equivalency Privacy)
  • WPA(Wi-Fi Protected Access)
  • WPA2(Wi-Fi Protected Access 2)
  • WPA2 with WPS(Wireless Protected Setup)
  • WPA3(Wi-Fi Protected Access)

For this post we will only be focusing on WPA2 because that’s the one most commonly used.

WPA2 uses the Advanced Encryption Standard (AES) and Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP), respectively.

Developed by the U.S. government to protect classified data, AES comprises three symmetric block ciphers. Each encrypts and decrypts data in blocks of 128 bits using 128-bit, 192-bit and 256-bit keys. Although the use of AES requires more computing power from APs and clients, ongoing improvements in computer and network hardware have mitigated performance concerns.

CCMP protects data confidentiality by allowing only authorized network users to receive data, and it uses cipher block chaining message authentication code to ensure message integrity.

WPA2 also introduced more seamless roaming, allowing clients to move from one AP to another on the same network without having to reauthenticate, using Pairwise Master Key caching or preauthentication.

WPA2 Password Hacking

Okay, so hacking WPA-2 PSK involves 2 main steps-

  • Getting a handshake (it contains the hash of password, i.e. encrypted password)
  • Cracking the hash.

What we need is:

  • An attacker (you)
  • A client
  • An AP (Access point)
  • A network adapter capable of packet injection. (i recommend ALFA AWUS036NH)

When the client and the AP communicate in order to authenticate the client, they have a 4 way handshake that we can capture. This handshake has the hash of the password. Now there’s no direct way of getting the password out of the hash, and thus hashing is a robust protection method. But there is one thing we can do. We can take all possible passwords that can exists, and convert them to hash. Then we’ll match the hash we created with the one that’s there in the handshake. Now if the hashes match, we know what plain text password gave rise to the hash, thus we know the password. If the process sounds really time consuming to you, then its because it is. WPA2 hacking (and hash cracking in general) is pretty resource intensive and time taking process. Now there are various different ways cracking of WPA2 can be done. But since WPA2 is a long shot, we shall first look at the process of capturing a handshake.

Now since i don’t want you to remain script kiddies forever, let me explain what the 4 way handshake actually is.

The Four-Way Handshake

The authentication process leaves two considerations: the access point (AP) still needs to authenticate itself to the client station (STA), and keys to encrypt the traffic need to be derived. The earlier EAP exchange or WPA2-PSK has provided the shared secret key PMK (Pairwise Master Key). This key is, however, designed to last the entire session and should be exposed as little as possible. Therefore the four-way handshake is used to establish another key called the PTK (Pairwise Transient Key). The PTK is generated by concatenating the following attributes: PMK, AP nonce (ANonce), STA nonce (SNonce), AP MAC address, and STA MAC address. The product is then put through PBKDF2-SHA1 as the cryptographic hash function.
The handshake also yields the GTK (Group Temporal Key), used to decrypt multicast and broadcast traffic.

The actual messages exchanged during the handshake are depicted in the figure and explained below:

Here is YouTube video for a better understanding.

The Aircrack-ng suite

Aircrack-ng is a complete suite of tools to assess WiFi network security.

It focuses on different areas of WiFi security:

  • Monitoring: Packet capture and export of data to text files for further processing by third party tools
  • Attacking: Replay attacks, deauthentication, fake access points and others via packet injection
  • Testing: Checking WiFi cards and driver capabilities (capture and injection)
  • Cracking: WEP and WPA PSK (WPA 1 and 2)

Here is a breakdown of tools that we would use:

  • Airmon-ng (for initiating monitor mode)
  • Airodump-ng (to capture the handshake)
  • Aireplay-ng (to deauthenticate clients)
  • Aircrack-ng (to brute force the password)

Step 1 Set your interface to monitor mode.

Monitor mode or RFMON (Radio Frequency Monitor) mode, enables a device with a wireless network interface controller to monitor all traffic received from the wireless network. Unlike promiscuous mode, which is also used for packet sniffing, RFMON mode enables packets to be captured without having to connect or link with an access point. RFMON mode only works with wireless networks, while promiscuous mode can be applied to both wired and wireless networks.

Now wlan0 is for me, for you it could be wlan1 or wlan2 anything else, depending on you card. So select the interface carefully.

As you can see station mode is disabled and monitor mode is now enabled.

Step 2 Find your target.

Find you targets BSSID by this command:

Yes i know there’s a lot of information over there, so lets break that down as well.

PWR: Signal strength
RXQ: Receive quality
Beacons: Number of announcement packets.
#Data: Number of captured packets
CH: Channel
ENC: Encryption Type
Cipher: Cipher type
Station: MAC address of the client.
Lost: Packets lost
Packets: Data packets sent by client

Anyways, as you can see in the picture above, our target is called Test Router.

Step 3 Capture the Handshake

You will see something like this

The below area is to display clients connected to that AP. Now we need to simultaneously de-authenticate at least one client. In this case will de-authenticate 7A:AC:AD:CC:44:05.

So open another terminal

The command is

The -a is for the APs MAC address, the -c is for the clients MAC and -0 is for deauth mode.

After a few seconds press CTRL-Z to stop sending deauth packets. As soon as the client connects back, we would capture the hashed handshake file.

You can see on the top right corner that we captured the handshake file.

Step 4 Brute Forcing the handshake file

I have put the actual password in the file dic.txt along with some other random passwords. So we run aircrack-ng with the dictionary as well as the handshake file (.cap)

Now depending on your dictionary this can take a second or even weeks. I cracked it in a second because the dictionary was small and it contained the password.

Now you may be thinking that this isn’t the most efficient way of getting someones password.

Apple Wifi Password Change

Well the purpose of this article was to explain the basic attack vector used to hack WiFi passwords and to introduce you to the Aircrack-ng. If you want someones password, just go ask them.

Finding Wifi Password On Mac

There is another way we could get an APs (with WPA2) password and that is by exploiting the WPS pin vulnerability, we could get the password in just a few hours guaranteed, apparently that only works on old routers. So when i get a hold of one i’ll cover that topic as well.

Every type of WiFi encryption has its set vulnerabilities, for example the WEP has an issue with the implementation of the RC4 encryption algorithm. So stay tuned as i cover them one by one.

Almost everything we do on our Macs today requires a stable and fast internet connection: checking email, sending messages in a chat, hopping on a video conference call, downloading documents, etc. So when the quality of the WiFi signal drops, our lives nearly come to a standstill.

Luckily, you can learn how to extend WiFi range, how to make your WiFi faster, and ultimately how to boost WiFi signal throughout your office or home with the help of a few simple tricks.

Best Ways To Speed Up Internet On Mac

Knowing how to boost internet speed not only makes loading webpages and watching YouTube videos faster but also improves the WiFi signal reception throughout your space. You should start with simple solutions like checking your WiFi speed and restarting your router and gradually move towards more complicated ones like switching frequencies and updating firmware. Let’s go through the whole process step by step.

Test your WiFi speed

To understand the severity of your WiFi issues, the first thing you have to do is see how fast your WiFi signal is and then compare it to the speed you pay your ISP (internet service provider) for:

  1. Visit speedtest.net
  2. Click Go

Restart your WiFi router

The easiest solution for how to make WiFi faster is to simply reset your router. Find where the router is in your space (often connected to a cable or phone line). On the back, the device should have an on/off button — press it to turn the router off and then again to turn it back on. Wait for about 30 seconds and check if this WiFi speed booster option worked on the speedtest.net website.

Check your network diagnostics

If you see that your Mac WiFi booster is underperforming or not working at all, you can ask your Mac for advice too:

  1. Hold down Option and click on the WiFi icon in your menu bar

  2. Select Open Wireless Diagnostics

  3. Click Continue

  4. Follow the instructions given

Additionally, try switching web browsers (e.g. between Google Chrome, Safari, and Firefox) or use an Ethernet cable to connect to your router directly. If the cable doesn’t work, it means that the problem is either with the router itself or the internet connection to your house and not limited to just WiFi. Call your ISP.

Analyze your WiFi coverage

It’s entirely possible that you’ll get a better answer to how to improve internet speed in your house if you take some time to analyze how evenly your WiFi actually covers your home (or office). To do so properly, however, you need a high-quality WiFi booster for Mac.

NetSpot is a robust Mac WiFi network analyzer that will scan all the nearby connections and give you every data point you need to know for troubleshooting. In addition, the app lets you upload a map of your space (or even draw one) to check your coverage precisely and see where the signal breaks down.

Adjust your WiFi router

Since you now have a clear WiFi coverage map, you can start physically moving your router a bit closer to the areas where the coverage is poor. A few guidelines to help you:

  1. Position the router away from outside walls and as centrally as possible

  2. If you have more than one floor in your space, putting the router on the top floor will work better than keeping it on the ground one

  3. If you don’t have much leeway moving the router around, at least make sure to elevate it in its place as much as possible

  4. Remove any obstructions between your router and your space (e.g. don’t hide it in a closet)

  5. For routers with antennas, make sure to point them straight up or in the direction where the WiFi signal is weakest

Remove non-essential devices

Another idea for how to speed up WiFi is to simply disconnect all the extra devices you don’t need to be on your network. If it’s in your office, maybe you can limit the number of phones that are connected to the network at any given time. In your home, maybe it’s worth disconnecting your Xbox, printer, or a laptop that you don’t use very much.

Update router firmware

Most of the time, your router gets automatic updates. But sometimes outdated router firmware might not let you boost WiFi signal appropriately, so you need to update it manually:

Wifi Hacking App Download

  1. Find your router admin settings on the back (192.168.x.xxx), along with username and password

  2. Type the number into your URL address bar in the browser and log in

  3. See if there’s an upgrade to your router available

Use a 5 GHz WiFi band

Most routers now support two different WiFi bands: 2.4 GHz and 5 GHz. How do I know which WIFI channel is best? Since nearly every device uses the 2.4 GHz frequency by default, including all the gadgets your neighbors have, it could help to switch to the 5 GHz one to see better results. The 5 GHz band is also able to send more data, although it’s not as good at going through walls as 2.4 GHz.

You can create a 5 GHz band network right from your router’s admin panel. Make sure to give it a distinctive name or just add 5 GHz at the end so you can differentiate between the two. Once done, go to System Preferences ➙ Network ➙ Advanced and move the newly created network to the top to automatically connect to it first.

Buy a new WiFi router

If you need more ideas for how to increase WiFi speed, why not look into updating your router? It’s likely that your device came for free with your ISP and, chances are, it’s a bit outdated and not that powerful.

The standard router denomination is 802.11. While most old routers are 802.11g and 802.11n, you really want to get the latest 802.11ac one, which handles queries like video streaming much better. You might even call your ISP and ask to update your current router for free, if possible.

Extend your WiFi network

The best answer by far to how to make WiFi stronger in a large house or space is to get a WiFi signal booster on Mac. Essentially, what it does is accept a weak WiFi signal and amplify it in the parts of your home where reception is not good otherwise.

There are lots of alternatives for WiFi extenders on the market. TP-Link RE220 presents a good and low-cost option you can spread out through your home as does Netgear Nighthawk X6 EX7700. But how do you know where you need to boost WiFi signal exactly?

WiFi Explorer is a complete monitoring solution for your internet connection. Launch this app from the various spots in your home and it will perform a complete analysis of your area, including all the networks, channels, bands, download speeds, and more. Then place WiFi speed boosters anywhere you see signal degradation.

Create an LTE hotspot

In case you’re trying to figure out how to boost WiFi speed while your WiFi is down, you still need access to the internet. Initiating a hotspot from your iPhone is a logical way out, but you need to make sure that your Mac is using the LTE network only for troubleshooting and doesn’t automatically go downloading some irrelevant update.

TripMode is a handy menu bar utility that restricts your Mac’s internet connection to save you precious data. For example, you can only allow access to Safari and block your backup software or media downloader. You also automatically see the amount of data being used and stay in control to avoid any surcharge on your phone plan.

As you can see, there are plenty of ways for how to boost WiFi signal on Mac, from adjusting the positioning of your router to using apps like WiFi Explorer and NetSpot to find the best frequency to connect to. Even in case, your WiFi is completely down, you can use TripMode to find a solution via your iPhone hotspot.
