Weak and easy-to-guess passwords make even the soundest cybersecurity strategy easy to bypass. If a hacker guesses or cracks a password, the intruder can access your account or system without raising the alarm and compromise whatever asset you kept safe behind a password.

The guide below provides 11 strong password ideas that will help you stay a step ahead of hackers. We also explain the difference between sound and weak passphrases, provide tips on improving current passwords, and show the main methods hackers rely on to crack credentials.
A brute force attack is a simple process in which a program automatically cycles through different possible combinations until it guesses the target password. These programs can easily crack simple and medium passwords.
An average brute force program can try over 15 million key attempts per second, so 9 minutes is enough to crack most seven-character passphrases. Brute force attacks are the main reason why we insist on a 12-character minimum for passwords.
A hacker can intercept credentials when victims exchange passwords via unsecured network communications (without VPN and in-transit encryption). Also known as sniffing or snooping, eavesdropping allows a hacker to steal a password without the victim noticing something is wrong.
Hackers typically gather tens of thousands of different credentials leaked from another hack. Unfortunately, as many people use the same simple passwords, this method is very effective. Another name for credential recycling is password spraying.
Hello aspiring ethical hackers. In this article, you will learn about a tool named Wifite. It is an automatic Wireless password cracking tool that tries almost all known methods of wireless cracking like Pixie-Dust attack, Brute-Force PIN attack, NULL PIN attack, WPA Handshake Capture + offline crack, The PMKID Hash Capture + offline crack and various WEP cracking attacks.Wifite is installed by default on Kali Linux. Just like any wireless password cracking method, Wifite needs monitor mode to be enabled on the wireless interface as shown below. However, it automatically enables this monitor mode but if it fails to enable it, you can enable it manually as shown below.
I will explain the mathematical rationale for some standard advice, including clarifying why six characters are not enough for a good password and why you should never use only lowercase letters. I will also explain how hackers can uncover passwords even when stolen data sets lack them.
That is more than 62 trillion times the size of the first space. A computer running through all the possibilities for your 12-character password one by one would take 62 trillion times longer. If your computer spent a second visiting the six-character space, it would have to devote two million years to examining each of the passwords in the 12-character space. The multitude of possibilities makes it impractical for a hacker to carry out a plan of attack that might have been feasible for the six-character space.
There are other ways to guard against password cracking. The simplest is well known and used by credit cards: after three unsuccessful attempts, access is blocked. Alternative ideas have also been suggested, such as doubling the waiting time after each successive failed attempt but allowing the system to reset after a long period, such as 24 hours. These methods, however, are ineffective when an attacker is able to access the system without being detected or if the system cannot be configured to interrupt and disable failed attempts.

This practice poses a serious problem for security because it makes passwords vulnerable to so-called dictionary attacks. Lists of commonly used passwords have been collected and classified according to how frequently they are used. Attackers attempt to crack passwords by going through these lists systematically. This method works remarkably well because, in the absence of specific constraints, people naturally choose simple words, surnames, first names and short sentences, which considerably limits the possibilities. In other words, the nonrandom selection of passwords essentially reduces possibility space, which decreases the average number of attempts needed to uncover a password.
You can check whether any of your passwords has already been hacked by using a Web tool called Pwned Passwords ( ). Its database includes more than 500 million passwords obtained after various attacks.
Password crackers can decipher passwords in a matter of days or hours, depending on how weak or strong the password is. To make a password stronger and more difficult to uncover, a plaintext password should adhere to the following rules:
A password cracker may also be able to identify encrypted passwords. After retrieving the password from the computer's memory, the program may be able to decrypt it. Or, by using the same algorithm as the system program, the password cracker creates an encrypted version of the password that matches the original.
Some password cracking programs may use hybrid attack methodologies where they search for combinations of dictionary entries and numbers or special characters. For example, a password cracker may search for ants01, ants02, ants03, etc. This can be helpful when users have been advised to include a number in their password.
Unauthorized access to another individual's device can be grounds for criminal charges. Even guessing someone's password without the use of a password cracker can lead to criminal charges. Under U.S. state and federal laws, more charges can be added depending on what threat actors do once they gain unauthorized access.
Password attacks are one of the most common forms of corporate and personaldata breach. A password attack is simply when a hacker trys to steal yourpassword. In 2020, 81% of data breaches were due to compromisedcredentials.Because passwords can only contain so many letters and numbers, passwords are becoming less safe. Hackers know that manypasswords are poorly designed, so password attacks will remain a method ofattack as long as passwords are being used.
Man-in-the middle (MitM) attacks are when a hacker or compromised system sits in between two uncompromised people or systems and deciphers the information they're passing to each other, including passwords. If Alice and Bob are passing notes in class, but Jeremy has to relay those notes, Jeremy has the opportunity to be the man in the middle. Similarly, in 2017, Equifax removed its apps from the App Store and Google Play store because they were passing sensitive data over insecure channels where hackers could have stolen customer information.
A type of brute force attack, dictionary attacks rely on our habit of picking "basic" words as our password, the most common of which hackers have collated into "cracking dictionaries." More sophisticated dictionary attacks incorporate words that are personally important to you, like a birthplace, child's name, or pet's name.
If you've suffered a hack in the past, you know that your old passwords were likely leaked onto a disreputable website. Credential stuffing takes advantage of accounts that never had their passwords changed after an account break-in. Hackers will try various combinations of former usernames and passwords, hoping the victim never changed them.
In cryptanalysis and computer security, password cracking is the process of recovering passwords[1] from data that has been stored in or transmitted by a computer system in scrambled form. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password.[2] Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords.[3]
The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence to which a judge has allowed access, when a particular file's permissions restricted.
The time to crack a password is related to bit strength .mw-parser-output div.crossreferencepadding-left:0.mw-parser-output .hatnotefont-style:italic.mw-parser-output div.hatnotepadding-left:1.6em;margin-bottom:0.5em.mw-parser-output .hatnote ifont-style:normal.mw-parser-output .hatnote+link+.hatnotemargin-top:-0.5em(see Password cracking), which is a measure of the password's entropy, and the details of how the password is stored. Most methods of password cracking require the computer to produce many candidate passwords, each of which is checked. One example is brute-force cracking, in which a computer tries every possible key or password until it succeeds. With multiple processors, this time can be optimized through searching from the last possible group of symbols and the beginning at the same time, with other processors being placed to search through a designated selection of possible passwords.[4] More common methods of password cracking, such as dictionary attacks, pattern checking, word list substitution, etc. attempt to reduce the number of trials required and will usually be attempted before brute force. Higher password bit strength exponentially increases the number of candidate passwords that must be checked, on average, to recover the password and reduces the likelihood that the password will be found in any cracking dictionary.[5] 2ff7e9595c
