Various Password Attacks

The video tutorial discusses various types of password attacks, including online, offline, and non-technical methods. Offline attacks require access to password hashes, while online attacks are noisier and can alert administrators. Non-technical attacks involve social engineering tactics. Techniques such as dictionary, brute force, hybrid, and rule-based attacks are explained, along with the use of rainbow tables. The tutorial emphasizes the importance of understanding these methods for ethical hacking and cybersecurity.

What is a key requirement for executing an offline password attack?

• Access to the system's web form

• Knowledge of the victim's username

• Acquisition of the password hash

• Administrator privileges

Which of the following is a non-technical attack method?

• Brute force attack

• Phishing

• Rainbow table attack

• Hybrid attack

How does a dictionary attack attempt to guess a password?

• By using a list of common words

• By trying every possible character combination

• By exploiting network vulnerabilities

• By using precomputed hash values

What is a hybrid attack?

• An attack that uses precomputed hashes

• An attack that relies on social engineering

• An attack using only uppercase characters

• A combination of dictionary and brute force attacks

What is the purpose of a rainbow table in password attacks?

• To reset passwords on a system

• To provide a list of potential passwords

• To compare hashes with precomputed values

• To store usernames and passwords
