Adobe got hacked and about 150 million people’s account details have been leaked. You should be aware that the passwords are encrypted with a single key using a symmetric and reversible algorithm. This means when anyone figures out the key to decrypt the passwords, they'll be able to decrypt every single password on the list, no matter how strong or random your password was. So far no one has been able to reverse-engineer the Adobe decryption key, but it's probably a matter of time. This could all have been avoided if Adobe had used a cryptographic hash function.
