What are some real-world examples of hash attacks?

What are some real-world examples of hash attacks?

Hash attacks often target systems that rely on hashing for security. A notable example is the 2012 LinkedIn breach, where attackers used a hash collision attack to compromise user passwords.

How did the attackers exploit the hash function in that case?

The attackers exploited weak hashing algorithms, specifically SHA-1, which allowed them to generate collisions and recover original passwords from the hashed values.

Are there any other significant incidents involving hash attacks?

Yes, another significant incident was the 2014 breach of eBay, where attackers used hash cracking techniques to access user accounts.

What can organizations do to protect against hash attacks?

Organizations should use strong, modern hashing algorithms like bcrypt or Argon2, implement salting, and regularly update their security practices.
