Hackers can use different strategies to crack password (dictionary,brute forceand rainbow tables are the most common ones). In this article, we’ll focus on the rainbow table attack, but you can find explanation about the other ones on this website if you are interested too. How does a ra...
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 Never use outdated hashing algorithms in rainbow tables since they are now easy to crack.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...
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 ...
The higher the entropy, the less vulnerable you are to a variety of cyber threats,such as brute-force attacks, in which a threat actor uses automated software to figure out your password. Then there are alsorainbow table attacks, which revolve around utilizing tables of hashed passwords to gai...
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...
Using “rainbow tables” for popular hashing algorithms that contain common passwords and their hashed counterparts.If they find any of the leaked password hashes in the table, they’ll be able to see the corresponding original. This effectively reverses the hashing, letting them know the informati...
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...

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. Want to ...
Tools That Compute Pre-Scan Rainbow Tools Some tools can be used to pre-scan the rainbow tables for all known inputs and outputs of the hash functions. These hash functions are nothing but algorithm-based encryption methods that are used to convert passwords into long series of numbers and le...
