Birthday attacks: MD5 is also vulnerable to birthday attacks, where an attacker can create a second message with the same hash value as the original message. This can be used to create fraudulent digital signatures and certificates. 3. Other attacks: MD5 is also vulnerable to other attacks, such as preimage attacks and chosen-prefix collisions. ...
