How Fast Can AI Crack Passwords?

Aug 10, 2023 - homesecurityheroes.com
The article discusses the use of an AI password cracker, PassGAN, to estimate how long it would take AI to crack passwords in 2023. The AI was run through a list of 15,680,000 passwords, revealing that passwords with less than 7 characters, regardless of their composition, can be cracked instantly or in less than 6 minutes. Passwords with more than 18 characters are generally safe against AI password crackers, taking at least 10 months to crack number-only passwords and up to 6 quintillion years to crack passwords containing symbols, numbers, and both lower and upper-case letters.

PassGAN represents a significant advancement in password cracking techniques, using a Generative Adversarial Network (GAN) to learn the distribution of real passwords from actual password leaks, thereby eliminating the need for manual password analysis. The article concludes with advice on how to protect passwords, including using at least 15 characters, a mix of upper and lower-case letters, numbers, and symbols, changing passwords every 3 to 6 months, and avoiding the use of the same password across multiple accounts.

Key takeaways:

  • AI password cracker, PassGAN, can crack 51% of common passwords in less than a minute, 65% in less than an hour, and 81% in less than a month.
  • Passwords longer than 18 characters are generally safe against AI password crackers, taking at least 10 months to crack number-only passwords and 6 quintillion years to crack passwords that contain symbols, numbers, lower-case letters, and upper-case letters.
  • PassGAN represents a significant advancement in password cracking techniques, using a Generative Adversarial Network (GAN) to learn the distribution of real passwords from actual password leaks, making password cracking faster and more efficient.
