What are hash collision attacks and can you give me examples?

Hash collision attacks occur when two different inputs produce the same hash output. This can lead to security vulnerabilities.

Can you provide a real-world example of a hash collision attack?

One famous example is the MD5 hash collision found by researchers in 2004, which allowed attackers to create fake SSL certificates.

How do these attacks affect data integrity?

They can compromise data integrity by allowing malicious actors to substitute legitimate data with fraudulent data without detection.

What measures can be taken to prevent hash collision attacks?

Using stronger hash functions like SHA-256 and implementing additional security layers can help mitigate these risks.
