Hello tekgyd reader today i am share top ten password cracking methods.
What is Password Cracking?
Password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A common approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password. Generally Password cracker not hacking a password ,these software is only recover your password

Top 10 Password Cracking Methods
1. Dictionary attack
This uses a simple file containing words that can, surprise surprise, be found in a dictionary. In other words, if you will excuse the pun, this attack uses exactly the kind of words that many people use as their password.
A dictionary attack is based on trying all the strings in a pre-arranged listing, typically derived from a list of words such as in a dictionary . In contrast to a brute force attack, where a large proportion of the key space is searched systematically, a dictionary attack tries only those possibilities which are deemed most likely to succeed. Dictionary attacks often succeed because many people have a tendency to choose short passwords that are ordinary words or common passwords, or simple variants obtained, for example, by appending a digit or punctuation character. Dictionary attacks are relatively easy to defeat, e.g. by choosing a password that is not a simple variant of a word found in any dictionary or listing of commonly used passwords.
2. Brute force attack
This method is similar to the dictionary attack but with the added bonus, for the hacker, of being able to detect non-dictionary words by working through all possible alpha-numeric combinations from aaa1 to zzz10.
It’s not quick, provided your password is over a handful of characters long, but it will uncover your password eventually. Brute force attacks can be shortened by throwing additional computing horsepower, in terms of both processing power – including harnessing the power of your video card GPU – and machine numbers, such as using distributed computing models and zombie botnets.

3. Rainbow table attack
A rainbow table is a list of pre-computed hashes – the numerical value of an encrypted password, used by most systems today – and that’s the hashes of all possible password combinations for any given hashing algorithm mind. The time it takes to crack a password using a rainbow table is reduced to the time it takes to look it up in the list.
However, the table itself will be huge and require some serious computing horse power to run, and it’s useless if the hash it is trying to find has been ‘salted’ by adding random characters to the password before applying the hashing algorithm.
“There’s an easy way to hack: ask the user for his or her password. A phishing email leads the unsuspecting reader to a faked online banking, payment or other site in order to login and put right some terrible problem with their security…”
5. Social engineering
Social engineering takes the whole ‘ask the user’ concept outside of the inbox that phishing tends to stick with and into the real world.
A favourite of the social engineer is to telephone an office posing as an IT security tech guy and simply ask for the network access password. You’d be amazed how often this works. Some even have the necessary gonads to don a suit and name badge before walking into a business to ask the receptionist the same question face to face
6. Offline cracking
Often the target in question has been compromised via an hack on a third party, which then provides access to the system servers and those all-important user password hash files. The password cracker can then take as long as they need to try and crack the code without alerting the target system or individual user.

A key logger or screen scraper can be installed by malware which records everything you type or takes screen shots during a login process, and then forwards a copy of this file to hacker central.
Some malware will look for the existence of a web browser client password file and copy this which, unless properly encrypted, will contain easily accessible saved passwords from the user’s browsing history.
8. Shoulder surfing
The most confident of hackers will take the guise of a parcel courier, aircon service technician or anything else that gets them access to an office building.
Once they are in, the service personnel ‘uniform’ provides a kind of free pass to wander around unhindered, and make note of passwords being entered by genuine members of staff. It also provides an excellent opportunity to eyeball all those post-it notes stuck to the front of LCD screens with logins scribbled upon them.
Hackers have realised that many corporate passwords are made up of words that are connected to the business itself. Studying corporate literature, website sales material and even the websites of competitors and listed customers can provide the ammunition to build a custom word list to use in a brute force attack.
Really savvy hackers have automated the process and let a spidering application, similar to those employed by leading search engines to identify keywords, collect and collate the lists for them.
The password crackers best friend, of course, is the predictability of the user. Unless a truly random password has been created using software dedicated to the task, a user generated ‘random’ password is unlikely to be anything of the sort.
Instead, thanks to our brains’ emotional attachment to things we like, the chances are those random passwords are based upon our interests, hobbies, pets, family and so on. In fact, passwords tend to be based on all the things we like to chat about on social networks and even include in our profiles. Password crackers are very likely to look at this information and make a few – often correct – educated guesses when attempting to crack a consumer-level password without resorting to dictionary or brute force attacks.
