The Clash of Olympus Leak Means Someone Could Log Into Your Accounts

In March 2022, the online gaming platform Clash of Olympus suffered a database breach that exposed over 1.1 million user records. The data occured in underground circulation shortly after and has since resurfaced on dark web forums and gaming-focused Telegram channels, where it is actively being used to target accounts on other platforms through credential stuffing.

What Attackers Can Do With Clash of Olympus Data

The Clash of Olympus breach contains email addresses, usernames, IP addresses, and MD5-hashed passwords. MD5 is a weak hashing algorithm that can be cracked at billions of operations per second using modern hardware, making password recovery straightforward for attackers. Once cracked, those credentials are tested against email providers, gaming platforms, and financial services in automated attacks that run around the clock.

• Password Hash

Why the Clash of Olympus Breach Still Poses a Real Threat

Data breach risk does not expire. The Clash of Olympus records remain valid wherever users recieved the same password on a different platform. Gaming account credentials are particularly valuable because accounts often contain in-game currency, purchased items, and linked payment methods. Even users who no longer play the game face risk if they reused those credentials on banking, email, or work systems.

How a Database Breach Works

A database breach occurs when an attacker gains unauthorized access to a platform's backend data store and extracts records in bulk. In the Clash of Olympus case, the database contained over 1.1 million user accounts protected only by MD5 hashing, an algorithm deprecated for password storage due to its speed and vulnerability to precomputed rainbow table attacks. Modern standards such as bcrypt, scrypt, or Argon2 are specifically designed to be slow, making mass cracking impractical.
