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...

Rainbow tables calculate the hash function of every string placed in the table. A rainbow table is constructed using chains of both hashing and reduction functions. Common plaintext passwords are repeatedly passed through a chain of these operations and then stored in the table next to their corre...
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 ...
A rainbow table is a hash function used in cryptography for storing important data such as passwords in a database. Sensitive data are hashed twice (or more times) with the same or with different keys in order to avoid rainbow table attacks. Some of the most highly-rated cryptos use ...

There are multiple potential uses, explains Chester Wisniewski, senior security adviser for data security firm Sophos. For hackers around the world, the huge trove of new leaked passwords is an opportunity to update their “rainbow tables”—vast databases that serve as a digital key for cracking...
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 ...
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 Never use outdated hashing algorithms in rainbow tables since they are now easy to crack.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...
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...
