Rainbow tables: Involves pre-computing the hashes for possible passwords and storing them in a ‘rainbow table’. This allows a hacker to quickly look up the hash of a stolen password and find the original password. Phishing Phishingis a technique where attackers masquerade as a trustworthy enti...
What is a rainbow table and how can it be mitigated? Are rainbow tables still a viable option for an attacker? Give some examples of how you could prove a user (opened a file || executed an application) What is the NTDS.dit file? Which registry hive would you need if you wanted ...
Usernames must not be used as salt as these are easy to acquire. Never use outdated hashing algorithms in rainbow tables since they are now easy to crack. Do not use a fixed salt, that is, the same salt for every hashed password. That would be very ineffective, especially for reused pa...
A Rainbow Table Attack is a cryptographic attack method that uses precomputed tables of hash values to quickly reverse-engineer plaintext passwords from... Red Team vs. Blue Team “Red team vs. blue team” is a cybersecurity drill during which one group, dubbed the “red team,” simulates...
RainbowCrack.This tool generates rainbow tables to use for hash and password cracking. What are examples of brute-force attacks? In 2009, attackers targeted Yahoo accounts using automated password cracking scripts on a Yahoo web services-based authentication application thought to be used byinternet se...
Password pepper is yet another additional security layer protecting against brute force attacks, dictionary attacks, and rainbow tables. Read on to find out what a password pepper is, how it works, and how it can improve your cybersecurity. Contents: What is a password pepper? How does ...

This process, called “salting,” ensures distinct output even when the inputs are identical. For instance, a rainbow table or a dictionary attack might be used by hackers to retrieve user credentials stored in a database. Salting prevents the tempering of data during such attacks. Data ...
RainbowCrack is one of the fastest cracking tools that leverage rainbow tables. Real-life Examples The Canadian Revenue Agency faced a brute force attack in 2020, compromising 11,000 accounts of CRA and other government-related services. Attackers used previously stolen credentials to brute force the...
“optimized lookup tables” that can be used to reverse-engineer one-way hash functions. A rainbow table is basically a pre-computed set of plaintext strings and their corresponding hashes. Large rainbow tables are publicly available, and attackers can use one of these tables to retrieve ...
