Chumpcar

Chumpcar, also known by its alias, is an organization headquartered in the United States of America. It operates an online forum accessible via the domain forum.chumpcar.com. The forum provides a platform for users to create accounts and participate in discussions. To enable access, the system stores usernames alongside hashed versions of passwords. This setup allows members to log in and contribute content while protecting credentials through hashing. The service is available to individuals who register and agree to the forum’s terms of use.

On November 10, 2015, the forum.chumpcar.com site suffered a security breach carried out by an actor known as Eggfather. The attacker obtained a copy of the user database containing 15,276 usernames and their corresponding password hashes. This incident highlighted the organization’s reliance on password hashing as a security measure for stored credentials. The breach drew attention to the forum’s user base size at that time, indicating at least fifteen thousand registered accounts. Chumpcar’s headquarters location in the United States places it under relevant national data protection considerations. The event remains a notable point in the organization’s public history regarding information security.
