Null Byte is a white hat hacker world for anyone interested in hacking, science, networking, social engineering, security, pen-testing, getting root, zero days, etc.
We have two love affairs: computer hacking and internet marketing. We list and review our favorite hacking and growth marketing tools for Hacking Articles is a comprehensive source of information on cyber security, ethical hacking, penetration testing, and other topics of interest to information security professionals. Cain is an easy application to install and configure. However, there are several powerful tools that should only be configured after you fully understand both the capabilities and consequences to the application and the target network.
Proceed with caution. Connect to a computer and install the Abel remote app. Harvest user account information. Crack user account information passwords to get the admin account. Login to the target machine with the admin account.
Install the Abel service on. First things first, after you launch the application you will need configure the Sniffer to use the appropriate network card. If you have multiple network cards, it might be useful to know what your MAC address is for your primary connection or the one that you will be using for Cain network access. You can determine your MAC address by performing the following steps:. Determine which one of the Ethernet adapters you are using and copy the MAC address to notepad.
You use this to help determine which NIC to select in the Cain application. With the Cain application open, select the Configure menu option on the main menu bar at the top of the application.
The Configuration Dialog box will appear. It may also be known as an Ethernet hardware address EHA , hardware address or physical address. It is also the name of the program for manipulating these addresses in most operating systems.
Now after launching the application, we have to configure it to use appropriate network card. To get the MAC address of your network interface card, do the following:. Now clickConfigure on the main menu. It will open the configuration dialog box where you can select the desired network interface card.
This tab has the most standard services with their default port running on. You can change the port by right-clicking on the service whose port you want to change and then enabling or disabling it. Here is an example:. Accept-Language: it.
Accept-Encoding: gzip, deflate. Host: xxx. Connection: Keep-Alive. Traceroute is a technique to determine the path between two points by simply counting how many hops the packet will take from the source machine to reach the destination machine. Cain also adds more functionality that allows hostname resolution, Net mask resolution, and Whois information gathering. The certificate can be used to verify that a public key belongs to an individual.
In a typical public key infrastructure PKI scheme, the signature will be of a certificate authority CA. In either case, the signatures on a certificate are attestations by the certificate signer that the identity information and the public key belong together.
This tab will collect all certificates back and forth between servers and clients by setting proxy IPs and ports that listen to it. Here you can set the custom challenge value to rewrite into NTLM authentications packets. We will import a local SAM file just for demonstration purposes to illustrate this point. Here is how to import the SAM file:. As you can see from the previous image, there are various types of techniques that are very effective in password cracking.
We will look at each of their definitions. In contrast with a brute force attack, where a large proportion key space is searched systematically, a dictionary attack tries only those possibilities which are most likely to succeed, typically derived from a list of words for example a dictionary hence the phrase dictionary attack. Generally, dictionary attacks succeed because many people have a tendency to choose passwords which are short 7 characters or fewer , single words found in dictionaries or simple, easily predicted variations on words, such as appending a digit.
However these are easy to defeat. Adding a single random character in the middle can make dictionary attacks untenable. Such an attack might be utilized when it is not possible to take advantage of other weaknesses in an encryption system if any exist that would make the task easier. It consists of systematically checking all possible keys until the correct key is found. In the worst case, this would involve traversing the entire search space. The key length used in the cipher determines the practical feasibility of performing a brute-force attack, with longer keys exponentially more difficult to crack than shorter ones.
A cipher with a key length of N bits can be broken in a worst-case time proportional to 2 N and an average time of half that. One of the measures of the strength of an encryption system is how long it would theoretically take an attacker to mount a successful brute-force attack against it.
Tables are usually used in recovering the plain text password, up to a certain length consisting of a limited set of characters. It is a practical example of a space-time tradeoff, using more computer processing time at the cost of less storage when calculating a hash on every attempt, or less processing time and more storage when compared to a simple lookup table with one entry per hash.
Use of a key derivation function that employ a salt makes this attack infeasible. Antony Peel. Software languages. Author Oxid. Updated Over a year ago. Last revision This year.
