Password cracking involves techniques to gain unauthorized access to accounts by guessing passwords. Common techniques include brute force attacks that try all possible combinations, dictionary attacks that use common password lists, and rainbow tables that reverse cryptographic hashes. Defenses include using strong, unique passwords, avoiding phishing scams, and implementing multi-factor authentication.

3. • Password cracking is a cybersecurity technique used to gain
unauthorized access to computer systems, networks, or online
accounts by attempting to guess or decrypt passwords.
• It is one of the oldest hacking arts. Every system must store
passwords somewhere in order to authenticate users.
• Password crackers use techniques like brute-force attacks, dictionary
attacks, phishing, malware, rainbow tables, and guessing to crack
passwords
Introduction

4. • A password is a secret sequence of
characters or symbols used to
authenticate a user's identity and grant
access to a computer system, network, or
online account.
• Comprises :
[a-z,A-z,0-9,@,$ etc.]

Password cracking techniques

6. (1) Brute Force attack
• This technique involves trying every
possible combination of characters
until the correct password is found.
• Brute force attacks are resource-
intensive and time-consuming but
can be effective if the password is
weak or short
Password cracking techniques

7. (2) Dictionary attack
• In this method, a list of commonly used
passwords or words from a dictionary is used
to attempt to gain access to an account.
• These lists can be created manually or
obtained from previous data breaches.

8. (3) Rainbow-table attack
• Rainbow tables are precomputed tables
used for reversing cryptographic hash
functions to obtain the plaintext
password from its hash.
• This technique can significantly speed
up the process of password cracking,
especially for weaker passwords.
• However, it requires a considerable
amount of storage space to store the

9. (4) Phishing
• Phishing involves tricking users into
providing their passwords by posing as a
legitimate entity, such as a bank or a social
media platform.
• Phishing attacks often use deceptive
emails, websites, or messages to trick
users into entering their login credentials.

10. (5) Keylogging
• Keyloggers are malicious software or
hardware that record keystrokes on a
computer or device.
• Attackers can use keyloggers to
capture passwords as users type
them, without their knowledge.

11. (6) Guessing
• Sometimes, attackers can successfully
guess passwords based on personal
information about the target, such as
their name, birthday, or interests.
• Keyloggers are malicious software or
hardware that record keystrokes on a
computer or device.

13. • In conclusion, password cracking is a persistent threat, but by
implementing strong security practices and promoting user
awareness, we can significantly reduce its effectiveness and protect
our digital assets.
