A new algorithm cracks 87 million passwords in less than 60 seconds, challenging current cybersecurity measures.

Cybersecurity specialists have discovered a sophisticated guessing algorithm capable of cracking 87 million passwords in less than 60 seconds. This breakthrough highlights the necessity for stronger security measures in our increasingly digital environment.

Revolutionary Algorithm

Kaspersky's recent study revealed a revolutionary algorithm that blends old brute-force tactics with powerful machine learning techniques. This smart guessing system can forecast and test the most likely password combinations first, significantly lowering the time required to crack them.

According to the data, 59% of 193 million credentials were hacked within 60 minutes, with an amazing 45% breached in less than a minute. By training on large password datasets, the system favours common character combinations, increasing its efficiency.

Antonov, a key researcher at Kaspersky:

"Smart algorithms make quick work of most passwords that incorporate dictionary sequences, and they even detect character alterations. "Using p@ssw0rd instead of password will not significantly slow down the algorithm."

How Does Smart Guessing Work?

Brute-force attacks, which loop through all conceivable combinations in search of a match, are generally inefficient. However, the smart guessing algorithm includes patterns such as dates, names, dictionary words, and keyboard sequences in its guessing technique. This makes it much more effective.

  • According to Kaspersky's results, traditional brute-force methods cracked 10% of passwords in less than a minute, but the smart algorithm increased this figure to 45%. Over an hour, brute-force attacks had a success rate of 20%, compared to 59% for smart-guessing.

  • Passwords created by humans tend to be predictable. Familiar names, significant dates, and common phrases are frequently employed. For example, in a YouTube experiment with over 200,000 people, the majority chose numbers like as 7, 37, 42, 69, 73, and 77 when asked for a random number between 1 and 100.
  • Even when attempting random character strings, users frequently choose the centre of the keyboard. Because algorithms are intended to spot these typical patterns and character replacements, their predictability makes password cracking easier.

Cybersecurity Implications

Individuals and companies are advised to establish stricter password procedures. Simple replacements such as "p@ssw0rd" instead of "password" provide minimal additional protection. To improve security, users should use more complicated and unpredictable passwords that include upper and lower case letters, digits, and special characters.

Improving Password Security

  • Your passwords should be at least 12 characters long and include letters, numbers, and symbols.
  • Avoid easily guessed information, such as names, birthdates, or common words and patterns.

  • Use Password Managers like LastPass and 1Password that can generate and store secure, unique passwords for all of your accounts.
  • Enable multi-factor authentication (MFA) which is another layer of security which can dramatically minimize illegal access.


With the development of smart guessing algorithms, individuals and organizations are advised to proactively strengthen their defenses by adopting more complex passwords to protect their digital identities and online activities.  It's also important to stay informed of the latest cybersecurity threats and protections.
