Medusa is a speedy, parallel and versatile brute-force password cracker for most popular protocols, including SSH, Telnet, and SMB. It is one of the tools available in Kali Linux, the open-source security and penetration testing platform, often used by ethical hackers.
Medusa was specifically designed to perform large-scale network password cracking operations.
Using Medusa, a hacker can perform brute-force attacks or dictionary attacks in an effort to guess the password of any user account on a system. Once Medusa obtains a user name, it attempts to gain access to remote services running on a targeted system.
It can be used to crack a variety of authentication types and protocols, including SNMP, HTTP Basic Authentication, Windows Live and more.
Medusa is a powerful tool, but it is important to use it responsibly. It should only be used for ethical and legal penetration testing purposes and not for any malicious activities.
What is password cracker?
A password cracker is a type of software program that is used to guessing or “cracking” passwords for a variety of purposes. This type of software is typically used by hackers and other malicious users to gain access to systems, websites, and other resources that are secured by passwords.
Many times these malicious users will use a combination of automated tools and custom programs to try and exploit any weaknesses in system security. Password crackers can also be used by legitimate users to recover lost or forgotten passwords.
In addition, some companies use password crackers to test the strength of the passwords they have in place to identify any potential vulnerabilities that could be exploited.
What are the hardest passwords to crack?
The hardest passwords to crack are those that are long, contain a combination of uppercase and lowercase letters, numbers, and symbols. Generating a password like this that is easy to remember can take some creativity, so it is best to think of something unique or personal to you.
Additionally, it’s important to make sure that one does not reuse passwords, as this can make it easier for malicious actors to gain access to accounts. Ways to make sure that one does not reuse passwords is to use a password manager, which stores and encrypts passwords so that one does not have to remember every single one.
What is the most common 6 digit password?
The most common six digit password varies depending on the source, however, 000000 and 123456 are two of the most commonly seen passwords. According to one source, the top three most common passwords of six digits are 123456, 111111, and 000000.
Other passwords on the list include 789456 and 654321, as well as passwords that are derived from the user’s personal information that is easily guessed, such as their birthdate or their phone number.
Password reuse is also a common practice, meaning that the same password is used across multiple accounts; this practice not only increases the risk of a security breach, but also makes it easier for hackers to guess your passwords.
In order to protect your online accounts, it is important to create strong passwords that include a mix of capital and lowercase letters, numbers, and special characters, and to change them regularly.
How easy it is to crack a password?
The answer depends on the type of password and the tools used to attempt to crack it. While some passwords can be cracked in a matter of seconds, others can take significant amounts of time and may be virtually impossible.
Generally speaking, the longer and more complex the password is, the more difficult it will be to crack.
The most common way to crack a password is by using brute-force attacks, which test every possible combination of characters until the correct password is discovered. This can be done in two primary ways: dictionary attacks and hybrid attacks.
Dictionary attacks work by testing every word contained in a given dictionary file; the more words contained in the dictionary, the more variations the attack can generate. Hybrid attacks, on the other hand, mix words with numbers and other characters to generate more complex passwords.
Another way of cracking passwords is by using social engineering. This involves attempting to acquire information about the user and their possible passwords through indirect means such as guessing and researching.
In general, cracking a password is not impossible but it inevitably takes some time and effort. The best way to protect yourself from someone attempting to crack your password is by using a combination of numbers, letters, and special characters in order to make it as complex as possible.
Additionally, it’s also a good idea to use different passwords for different accounts and to update them regularly.
What is the number 1 most used password?
The number 1 most used password is “123456. ” This simple password appears in the list of the most commonly used passwords on numerous website security reports. According to the Keeper Security 2019 Report, “123456” was the most commonly used password, appearing over 23 million times in leaked password lists.
It also appears as the most commonly used password in the National Institute of Standards and Technology’s 10,000 most common passwords list. “123456” is an easily guessable and insecure password, so experts advise that users should never use it or other easy-to-guess passwords.
Instead, they should create complex, unique passwords that include at least eight characters and a combination of letters, symbols and numbers.
How fast a password can be cracked?
That depends on a number of factors, such as the complexity of the password used and the resources available to the person attempting to crack the password. Generally speaking, a simple password such as ‘123456’ or a single word will require a very short amount of time to crack.
On the other hand, passwords that contain multiple characters, numerical values, letters, and symbols, such as ‘p@$$w0rD123’, can potentially take significantly longer to crack.
The computing power and number of computers used by the persons attempting to crack the password can also significantly influence the time it takes to crack a password. The more powerful the computers used, or the more computers used in tandem, the shorter the amount of time it will take.
The type of computer system the password is stored on or the type of encryption used also affects the speed of password cracking. Many computer systems come with built-in security measures that make cracking passwords more difficult.
Therefore, someone attempting to crack the password may need to bypass those security measures first, before they can go about actually attempting to crack the password.
Finally, the type of password-cracking technique being used will also affect the speed at which a password can be cracked. Some password-cracking techniques can utilize powerful algorithms, while others may be more basic and take a longer period of time to crack the password.
In conclusion, the exact amount of time a password may take to crack is difficult to identify, as there are so many variables that come into play. However, with the right combination of resources, people can potentially crack passwords in a relatively short period of time.
How many passwords are hacked every day?
Unfortunately, there is no hard and fast answer to this question. It is estimated that an average of over 300,000 passwords are hacked each day, and it is likely higher than that. Hackers use a variety of tactics and tools to compromise passwords and access confidential data.
Unfortunately, due to the anonymity of the internet, it is difficult to track the exact number of passwords that are hacked each day. In fact, hackers often use the same passwords and techniques to breach multiple systems, meaning that one compromised password may affect hundreds of systems.
Even passwords with strong security measures, such as two-factor authentication, may still be vulnerable to attack, so it is important that users stay vigilant and use strong, unique passwords for each account.
How long does it take to crack a 4 digit PIN?
Cracking a 4-digit PIN can take a surprisingly short amount of time, depending on the processing power available. Brute force attacks, which involve systematically checking every possible combination of digits until the correct answer is found, can take anywhere from seconds to hours.
If a more sophisticated method is used, such as a dictionary attack involving words from a dictionary file, it can be cracked in a much shorter amount of time. In any case, the most efficient and effective way to protect your PIN is to set one that is at least 6-8 digits long and preferably composed of a mix of numbers, letters and other characters.
How secure is a 20 character password?
A 20 character password is extremely secure, provided the password is comprised of random numbers, letters, and symbols. If the password is used to protect sensitive data, the longer it is, the more secure it is.
With a 20 character password, it would take a hacker an incredibly long time to guess it. For example, according to SplashData, it would take an attacker 4 sextillion years to crack a 20 character password consisting of random characters via brute force attack.
However, the 20 character password used should always include a variety of uppercase, lowercase, numbers, and symbols to make it as strong as possible. Therefore, a 20 character password is extremely secure and is recommended if you need to protect ultra-sensitive data.
Which are common password cracking tools?
Password cracking tools are tools used by cyber criminals to gain access to confidential account data by attempting to “crack” passwords using various methods. The two most common tools used for password cracking are brute force attacks and dictionary attacks.
Brute force attacks involve using software to cycle through every possible password combination until a successful one is found; these tools can be very time consuming and often require significant computing power.
Dictionary attacks are based on a large library of common words and phrases and often allow an attacker to gain access quickly by trying common passwords. Other popular tools used for password cracking include rainbow tables, salting and hashed passwords, reverse engineering, and John the Ripper.
How many types of passwords are there?
There are a variety of different types of passwords. There are four main types that are commonly used: alphanumeric passwords, passphrases, PINs (Personal Identification Numbers), and biometric passwords.
Alphanumeric passwords are the most common type of password and are generally required in most online services. They contain both letters and numbers, and usually require a minimum length for increased security.
Passphrases are another type of password, which are generally much longer than an alphanumeric password. They often contain multiple words and a variety of characters, punctuation, and capitalizations.
Passphrases are more secure than alphanumeric passwords, but they can be more difficult to remember.
PINs (Personal Identification Numbers) are a type of password that are generally used with debit and credit cards. They typically consist of 4-6 digits, and provide an additional layer of security to protect the card experiences.
Biometric passwords are a type of secure authentication based on unique physical characteristics of a user, such as fingerprints or facial recognition. This type of password is generally used to secure sensitive data, such as financial accounts.
What is a common attacks used by hackers to discover passwords in a database?
A common attack used by hackers to discover passwords stored in a database is called a brute force attack. Using this type of attack, a hacker attempts to guess passwords by systematically trying every possible combination of characters.
Brute force attacks are often used in combination with other methods, such as dictionary attacks and rainbow tables, in order to generate as many potential passwords as possible. Additionally, brute force attacks can be used to guess answers to common security questions or to compromise any encryption used to protect the stored passwords.
It is important for database administrators to be aware of the risks posed by brute force attacks and to use secure encryption methods and strong password policies to mitigate these risks.
What are the two types of phishing?
Phishing is a type of cybercrime that involves fraudsters using deceptive tactics to acquire sensitive personal information from unsuspecting individuals. There are two types of phishing, known as Spear Phishing and Clone Phishing.
Spear Phishing is a more targeted form of cyberattack, where the malicious actors create customized emails designed to target a specific organization or individual. The emails usually contain links to malicious websites intended to harvest personal information, such as passwords and credit card numbers.
Clone Phishing is a technique that involves the malicious actor replicating a legitimate email and swapping out the links or attachments to direct the user to a malicious website. The email usually appears to be from a legitimate company or individual, making it hard to distinguish from authentic emails.
Both techniques are designed to fool users and to collect their personal data.
What is a common vulnerability with passwords?
A common vulnerability with passwords is weak or easily-guessed passwords. This means that passwords are too short, use easily-guessed words or phrases, or incorporate sensitive information like user names, birthdays, addresses, pet names, or phone numbers.
This makes it easy for malicious actors to guess or crack the passwords and gain unauthorized access to systems. It is also important to note that even strong passwords can be vulnerable if they are reused across multiple accounts, as malicious actors may gain access to multiple accounts with a single guess or guess combination.
Additionally, passwords that are not changed regularly are more vulnerable to attack. Taking the time to create strong, unique passwords that are changed periodically can go a long way in helping to secure systems and users’ data.
