Let's imagine the attacker may be any of the Computer number 2, 3 or 4. The victim man-in-the-middle would be Computer 1. This laptop would be the one running and serving wireless connectivity to the surroundings, and will have other interface connected to the wired network to access the internet.

Attackers may connect to the WLAN broadcasted by Computer 1 and then, use it to route all the traffic to the internet via this victim PC. From the internet point of view, it would look like it is Computer 1 originating the traffic! Wireless links from Computer 1 to all the attackers do not have to be a Wi-Fi connection - it may be a Bluetooth or any other type of wireless technology supported by all the parties that attempt to communicate with each other. Wireless Security - Hacking Methodology In this chapter, you will get a little more familiar with a variety of common tools that can be used in performing specific attacks or being a small step in more advanced attacks.

Later on, in the last section, you will need all this knowledge of tools combined together, and perform more advanced and complex types of wireless attacks. It is the last section of this tutorial that will go step by step through wireless security hacking scenarios and use the tools you saw until now, and the ones you will find here. WiFi discovery process is not against any law, since you are not acting offensively at any point, you are simply, passively listening to the Wi-Fi frequency bands, using your wireless client.

In order to discover what type of WLAN networks are present, you need to use specific tools that uses wireless hardware and listens on either a 2. Some of them are built-in to the operating system they are most often very ineffective for detailed WLAN analysis , and other ones are simple tools, which you can find on the internet. There are hundreds or thousands of tools out there in the market.

I will present to you 2 of them, that I really enjoyed due to its simplicity. What you will discover, while going through these chapters or you already know it from your experience , the tools delivered for Windows OS have better graphics and some fancy graphical features, opposite to what Linux-based tools provide.

But I can promise you, the ones based on Linux provide exactly the same information just in more text-like format. On the other hand, it is a bit easier to write scripts, that takes outputs of one tools as the input to other ones. This is a simple tool that identifies WLANs present in the nearby vicinity. Another tool that performs the same functions in the Windows environment is NetStumbler.

The information which you can extract from the table at the bottom of the above screenshot provides everything you may look for, like SSID name, received signal strength, This is a lot of! You can also see, very fancy graphical "radar" showing, how far particular networks are, from your current location - the same information may be read from Signal dBm field. On the other side, when using Linux I use Kali distribution for penetration testers - you should try as well , the equivalent of that would be a tool called airodump-ng.

The set of information, that airodump-ng output to the user is shown in the following screenshot. Also, we have another well-known tool called as Kismet. Wardriving Wardriving is the process of finding a Wireless Network wireless network discovery by a person in a car using their personal laptop, smartphone or other wireless client tools. Basically, the intention is to find some free-access wireless network, that malicious user can use without any legal obligations. Examples might be some market, that offer free Wi-Fi, without registration or some hotel that you can just register with fake data.

The method of finding those WLAN's are exactly the same as described above in this wireless discovery section. GPS Mapping There is a number of satellites that orbit the globe, each of them sending a low-power radio signal towards the piece of earth it covers. The GPS device that you use, it may be for example a smartphone with google maps application started, receives that signal from multiple satellites at the same time.

The device itself combines those signals together and calculate current geographical location on earth. The idea of GPS mapping is to map a wireless network that the user encounters on the global map of wireless network in reference to its geographical location. One may use the already mentioned Kismet tool to map its wireless network to the geographical location, and then put its coordinates on the google earth map.

You can use this website to map GSM cellular network as well. Wireless Security - Traffic Analysis A process of wireless traffic analysis may be very helpful in forensic investigations or during troubleshooting and of course this is a great way of self-study just to learn how applications and protocols inter communicate with each other.

In order to the traffic analysis to be possible, first, this traffic needs to be somehow collected and this process is known as traffic sniffing. The most commonly used tools for traffic sniffing are Kismet and Wireshark. Both these programs provide a version for Windows as well as Linux environments.

A lot more is available to you in the dump of the wireless traffic. Most of the information you would get, would be used in all the attacks presented in the last chapter. They could be for example used as the input to offline brute-force attacks, in order to break encryption and authentication models used in the WLAN deployment. Usage of Wireshark in both Windows and Linux are very intuitive - both environments provide a GUI that looks the same for both systems.

When the program starts, you only need to indicate the physical interface, that would be used for traffic sniffing you can select any interface, either wired one or wireless one , and then proceed with traffic sniffing. Example of wireless packets collected by a wireless card is shown in the following screenshot. It is extremely useful, when you need to extract particular flows between a particular MAC addresses or between particular IP addresses out of hundreds of packs coming every second from all the wireless clients in the surrounding.

Using an example dump, we can see, that some set of information is in the form of unreadable data probably encrypted , and in The reason for that is that, hexadecimal representation is the original way the packet looks like, but Wireshark has thousands of "traffic templates", which are used to map specific HEX values to a known protocol field.

For example, in a You may save all your traffic dumps using the common. The other tool, that you should aware of, is Kismet. As soon as you start your Kismet tool and specify the mon0 interface, it will list all the SSID detected in your environment.

During the time Kismet is running, all the wireless packets are collected and stored in the. When you quit a program, you get a message, that all the wireless packet dumps have been saved and you can access them afterwards. In the example presented above, all the packet dumps have been stored in the binary files they are not in a readable format, when you open those files with "more" or "vi" or "nano", etc.. To open them correctly, you have to use Wireshark again!

Most often, a Passive Attack or rather passive information gathering is the 1st step before launching the wireless attack itself active part of the attack. Passive attacks are all the ones which do not require the attacker to communicate with any other party or inject any traffic. During passive attacks, a victim has no way to detect your activity because you are not acting , you are just hiding and listening to radio frequencies.

Passive attacks are not considered a law violation itself, however the use of information you got by passive attacks may be treated as a violation. For example, you are free to sniff listen to unencrypted traffic, collect it together and see that in fact, this is conversation between 2 people, but reading it and using the information included in this private conversation in some places of the world is a violation of the law.

The next step is to get the same IV vector inside the wireless frames, and the last step is to break the WEP encryption model offline. There is no single step in the attack that requires the attacker to communicate with victim in any way. Afterwards, an offline dictionary or offline brute-force attack is conducted on the collected encrypted packets.

If you are lucky enough, you might not communicate with the victim at all, and the attack is considered a pure passive attack. However, you may find a situation where the victim was authenticated to AP long before you came into play, and you don't want to wait any longer. Then, you may use an "Active Attack Step" in your general passive attack - inject wireless de-authentication frames, forcing the wireless victim to de-authenticate and then re-authenticate again, thus sniffing the new authentication 4-way handshake.

Sniffing the traffic between communicating parties Assuming that you somehow know the encryption key, you may sniff the communication between parties for example with Wireshark , and then decode the conversation since you know the keys. Assuming that parties were not using any protocols that is natively using encryption for example cleat text HTTP , you are free to see what the user was doing and track his moves on the internet.

Active attacks on the other hand are the ones, that require active participation in the wireless traffic forwarding or in injection of the wireless frames that affects WLAN operation. Performing active attacks leave tracks of malicious activity, therefore in some specific situation, the dumps collected by a victim using Wireshark or dumps from a WLAN card by forensic investigator regarding your activity may be a valid evidence in the court against you.

If you decide to use your knowledge in a malicious way. The attacker is directly injecting wireless packets that affect the wireless client telling them to de-authenticate , resulting in constant flapping of the state of wireless users from authenticated to de-authenticated and making the overall wireless experience very bad. It is a type of active attack, since the attacker is directly affecting the wireless behavior.

That way, client associates to "fake AP" that the attacker has just created and all the client traffic going to the internet is directly forwarded through attacker equipment attacker might do anything with this data then. Most of the attacks, you will ever see, would be a combination of the passive and the active steps. Passive ones are always a good starting point to understand the environment, to make a homework and get as many information about the potential victim as possible, etc.

The same approach corresponds to any type of hacking you may see, whether it is a web application hacking or social engineering hack or any other hacking approach. Wireless Security - Crack Wireless Attacks Whenever you might need to "crack" a wireless network, the task is about cracking the encryption, authentication or hash algorithm to derive some kind of secret password.

It might be doable, but to be very honest with you, now-a-days no one would use the algorithm that may be breakable, therefore, unless you are a high-class crypto analyst that would not be the way forward. Most of the approaches would concentrate on using some kind of dictionary or brute-force attack. Just to give you a simple idea of how this attack may be performed, imagine we have some password that "we don't know" - "MySecretPassword".

There are many ready tools that might be used for this purpose; we can create our own tools as well. Normally in real life you would use a dictionary file with hundreds of thousands of entries it is popular to download a prepared dictionary file from the internet, you can try to find one.

The idea behind this script would be to go through each and every password, and if the match between calculated hash matches the signature, we "would sniff" from the network, it means we have found a password. I have to state it was a simplified example, however it showed perfectly the concept itself.

During a wireless network cracking, you will most likely use a tool called aircrack-ng. The first type is the one that you can prepare by yourself or download from the internet and just reference it inside the script. The other approach is to rely on the internal airolib-ng dictionary that is the kind of internal dictionary database installed with the tool by default. Without making any real cracking at that point, I will show how to use aircrack-ng. I will use my very small dictionary which I have created in the example above with only 7 phrases inside, opposite to millions you would find in real dictionary file.

Additionally, I will not monitor any traffic in real-time, but I will use a. As you remember, data from the initial 4-way handshake is the only information that can lead to cracking the network. Data packets themselves are well encrypted and resistant to our attacks. I would wager a bet there is a staggeringly equal number of places online where you can learn one programming language or another.

Whether you are already one of those 11 million coding experts or a newbie to programming, there is a plethora of information out there to sort though. We have assembled a list of explanations to help you choose which language you may want to conquer next.

This will give you a roadmap and some early sense of which language might be the most appropriate one to learn for you. Mobile Apps When you want to develop apps for smartphones or tablets, your choice of language is largely dictated by the platform you want to develop for. If you want to target iOS devices, the standard language is Objective-C, when you develop for Android the default language is Java, and for Microsoft Surface and Windows 10 or 11 devices in general it is C.

And if your mobile app requires a server back-end running in the cloud, see the paragraph on server-side development below for additional languages. If you want to target all three mobile platforms and that sounds like a little bit too much to learn all at once, I recommend looking into cross-platform tools such as Altova MobileTogether that allow you to build one mobile app for all platforms from one source using XQuery and visual ActionTree scripting.

Web Development For developing websites both for the mobile web and classic desktop-based browsers, the programming language of choice that will be executed by the web-browser is JavaScript.

ASIC CHIPS AND ETHEREUM

If the team has a plus, that means they're the underdog and they'll have to either win the game or lose by less than the specified number for you to win. Each team will have different odds, so make sure you're paying attention to them. Not only will you be able to see any important information pop up, like injuries, but you'll also be able to see who the favorite is and who isn't.

In addition, being able to watch the line move will give you an idea of which team you should bet on and when you should bet. If you aren't really sure how things will turn out, it's a good idea to avoid betting altogether until the next game. To begin, either create an account or log in to your existing one. Next, simply choose the sport you want to bet on and go to that page. You'll then see all of the lines and games for the upcoming days.

The next thing you'll do is decide whether you want to bet on the favorite or the underdog. Once you know, go ahead and click on that team. From there, decide how much you want to bet and place it. Keep in mind, that once your bet is placed, you can't back out.

Spread betting works by allowing the sportsbooks to make two teams that are unbalanced to be more balanced. They do this by taking points from the favored team and giving points to the underdog, both of which will be labeled by either a plus or minus. The minus means the team is the favorite and they have to win by more than the number specified. The plus means the team is the underdog and they have to either win or lose by less than the specified number.

This means you can place a bet on both teams if you're confident it'll work out in your favor! Long is when you buy and short is when you sell. There will be two boxes with numbers and these are your buy and sell boxes. The long box will almost always have a lower price and the short box will have a higher one. In short, the price has to move a good amount of distance in order for you to win. This is true regardless of whether you're on the long or short side.

How to understand betting odds What is Leverage in Spread Betting? Leverage means that you'll only need to use a little bit of capital in order to open a larger position. In simple terms, this means you can put down a small deposit to open your position instead of having to pay a large amount. One thing to keep in mind, though, is that both profits and losses are much bigger because everything is determined by using the full trade value instead of the smaller deposit that you originally put down.

What is Margin in Spread Betting? There are two different types of margins in spread betting, which are deposit margin and maintenance margin. Deposit margin is the initial deposit you put down to actually open a position while maintenance margin is the amount you'll put in if your position starts accumulating losses that can't be covered by the deposit you put down. The good thing is you'll get something called a margin call, which is just a notification saying that you need to add more money and the reason why.

Moneyline Betting Explained Main Features of Point Spread Betting There are three main features of spread betting, which are the point spread, the favorite, and the underdog. Keep reading to see a more in-depth explanation of these below. The bigger the spread is, the bigger the underdog will be. Every sport and match or game is different, so make sure you know how to read multiple point spread bet types.

They use many things to figure this out, including how many people have bet on the team, how they've been doing during the season, how many players have been injured, and which team has home-field advantage. The Underdog The underdog is the team that isn't as popular and has a lower chance of winning. They are the team that has the plus sign in front and they usually lose more games than the favorite.

With that said, though, there's nothing that says they can't come out on top. The simple reason for this is because the sportsbook has the right to shift the odds and spread whenever they want. You have to remember they'll want to try and come out even, so they'll shift the odds and spread more towards their favor.

This is something you want to watch because you never know when it'll change. If possible, try and check the lines multiple times a day to ensure you're staying up-to-date on exactly what's going on. There are a few instances when it's a good idea to bet on a point spread. The first is when both teams are relatively equal because there's a higher chance that you can win your bet. Another instance is if you're trying to get a larger return.

These bets can give a great payout, but they can also cause you to lose a nice chunk of change. The final instance is when you know what you're doing and completely understand spread betting because placing a bet when you aren't sure what you're doing can lead to losing quite a bit of money. Benefits of Point Spread Bets Some of the benefits of these types of bets are listed next.

However, the moneyline in a bet like that could have a line for the Rams. The spread counteracts that value disparity but introduces an additional variable. Say the Rams are You may conclude that the Rams will win, but will they win by 15 or more?

Generally, a point spread betting line will almost always be roughly Now, there are times when betting on the moneyline makes more sense. When you see a -3 line, this is typically for when two teams are relatively equal in stature, but this could account for home-field advantage. When you see a spread less than three, it may be better value, depending on which side you want to wager, to bet the moneyline.

According to Sports Insights , the chances of winning an NFL game by less than three points is minimal. The betting line will almost always be different than , as 1. Also, with the runline of 1. Like MLB betting, the standard puckline is also 1. You can absolutely win money when betting the spread. However, there are a couple of easy strategies you can deploy immediately to assist in winning cash.

Whether getting a better betting line or adding 0. Look Toward Alternate Spreads Alternate line wagers may not be available at all sportsbooks, but it is something to consider. With this type of bet, you can bet on a different spread with the betting line value reflecting that change.

You may sacrifice some betting line value for that added point or two. Leverage Bonus Offers All online sportsbooks will have some form of a bonus or promotion offer. Some promos are tied to specific bets.
