Plot Twist: Combolists Are Still A Threat (2023)

FAQs

How long does it take to unhash a password? ›

For simple passwords that contain only numbers or lowercase letters, the results were almost instant. Meanwhile, the same system would need 400 years to decode them if stronger hashing functions like bcrypt are in use. For a complex 12-character password, the duration Hive estimate is 14 billion years.

If your password has been exposed in a data breach, you should immediately change the password on all affected accounts. Data breaches often occur as a means of obtaining sensitive information to commit further cybercrimes, such as identity theft or fraud.

A combo list is a collection of compromised usernames and their associated passwords that malicious actors use to populate their automated brute-forcing tools. As with any large dataset, combo lists have more value when they aggregate more credentials, typically incorporating data from multiple breaches.

Hashcat is a powerful tool that helps to crack password hashes. Hashcat supports most hashing algorithms and can work with a variety of attack modes. To enforce security and protect hashes from attacks, use strong passwords and salts before hashing passwords.

Because the hash function was designed by smart people to be hard to take the reverse of, they can't easily retrieve your password from it. An attacker's best bet is a bruteforce attack, where they try a bunch of passwords.

What is a combo email? ›

Combo is short for combination, so combo lists are lists containing combinations of usernames/emails and passwords. They are used for bruteforce attacks. The benefit compared to separate username and password lists is that combo lists are expected to contain a higher likelihood of success.

It's 123456, as hashed using a cryptographic protocol called MD5. The fact we know this hash corresponds to the world's most commonly used password should not be comforting, and it isn't, because MD5 has been cracked – the equivalent of thieves in heist films knowing exactly how to break open a safe.

To the time of writing, SHA-256 is still the most secure hashing algorithm out there. It has never been reverse engineered and is used by many software organizations and institutions, including the U.S. government, to protect sensitive information.

To protect passwords, experts suggest using a strong and slow hashing algorithm like Argon2 or Bcrypt, combined with salt (or even better, with salt and pepper). (Basically, avoid faster algorithms for this usage.) To verify file signatures and certificates, SHA-256 is among your best hashing algorithm choices.

Password salting is a technique to protect passwords stored in databases by adding a string of 32 or more characters and then hashing them. Salting prevents hackers who breach an enterprise environment from reverse-engineering passwords and stealing them from the database.

Hashing salting is essentially an additional step to keep passwords out of the hands of malicious hackers. It works rather simply, when a password is collected, salt is added to the password. This password is then hashed.

Can you reverse a salted hash? ›

In contrast, hashing cannot be reversed — it is essentially a form of one-way encryption. Salting is different, again, because it doesn't involve converting the original plaintext but simply complicates the text with additional characters.

Recovering a password from a hash value is generally considered impossible, at least in practical terms, because a hash function is designed to be a one-way function, which means that it is not reversible.

On average, it takes a hacker about two seconds to crack an 11-character password that uses only numbers. Throw in some upper- and lower-case letters, and it will take a hacker one minute to hack into a seven-character password.

When hashing passwords, two passwords can produce the same hash, so if a user inputs someone else's username but his own password, there is a possibility that he will be able to login to that other account.

Hashing is One-Way

Hashing works in one direction only – for a given piece of data, you'll always get the same hash BUT you can't turn a hash back into its original data.

Here is a quick guide to both

Computer programs used for brute force attacks can check anywhere from 10,000 to 1 billion passwords per second. There are 94 numbers, letters, and symbols on a standard keyboard. In total, they can generate around two hundred billion 8-character passwords.

Experts recommend using longer passwords when possible. The longer a password is, the more possible permutations it has, making it harder and harder for cybercriminals to crack.
