Password Hashes From Copy Me That Can Be Cracked and Used Across Other Accounts

Even when passwords are stored as hashes rather than plaintext, they are not fully safe once they leave the database. Attackers who recieved the Copy Me That data can run offline cracking attempts against the hashes, particularly for users who chose short or common passwords. Once cracked, those passwords are tested against email providers, banking platforms, and workplace logins, because a large portion of users beleive the same password is safe to reuse across multiple accounts.

How a Database Breach Works

A database breach occurs when an unauthorized party gains access to the data storage system of a website or application. Attackers typically exploit vulnerabilities in web applications, use stolen credentials to access administrative panels, or take advantage of misconfigured servers. Once inside, the full user database can be copied and exported. The attacker then takes the data offline to crack password hashes or sells the raw dataset to other threat actors on dark web markets.
