ThisHabbo Forum

In early 2014, ThisHabbo Forum, a fan community site for the Finnish social game Habbo, was compromised and user data from the forum was exposed. Our investigation team estimates the breach occurred around January 1, 2014, and our index of the incident contains 27,919 records tied to the site thishabboforum.com. The forum's administrators took the site offline after the hack, according to reporting by CyberInsurance.com. The breach surfaced publicly in early 2015 when the incident was verified and listed by breach-tracking services.

Limited public reporting: As of September 25, 2026, detailed company notices or major news coverage for this listing were limited in sources reviewed. The facts below rely primarily on the indexed fields plus any secondary sources cited.

January 1, 2014: Mozilla Monitor records the date of the ThisHabbo Forum breach as January 1, 2014, though the exact timing of the exploit was not clearly established.

March 28, 2015: The breach was verified and added to Mozilla Monitor's public database.

What Information Was Compromised?

Our analysis found the following data types in this breach: email addresses (27,919 records), usernames or forum nicknames (27,913 records), and IP addresses (27,713 records).

External sources indicate the exposed data also included passwords. Mozilla Monitor lists passwords among the compromised data, and CyberInsurance.com reports that the breach exposed email addresses, IP addresses, usernames, and passwords of approximately 28,000 forum members. Reporting elsewhere indicates the passwords were stored as salted hashes rather than plain text, which makes direct reading harder but does not eliminate the risk.

Not every individual is affected by every type of data listed here.

What Are the Potential Risks for Affected Individuals?

The most direct risk involves password reuse. Many people use the same password across multiple sites, so a forum password from 2014 can still unlock a current email or social media account today. Anyone who reused their ThisHabbo Forum password elsewhere should treat those accounts as exposed.

Email addresses and usernames in the hands of criminals also fuel phishing. Attackers can send convincing messages that reference the forum or Habbo to trick recipients into clicking malicious links or handing over more credentials. IP addresses add a smaller but real concern, because they can reveal approximate locations and service providers and support targeted scams. Even years later, old breach data circulates and is combined with other leaked records to build more complete profiles of individuals.

What Is ThisHabbo Forum Doing in Response?

According to CyberInsurance.com, the hack forced administrators to take the forum offline. The site later returned, and a lead post on the forum advised members that any old passwords would no longer work and had to be reset before signing in again. That amounts to a forced credential reset for the whole community. Beyond this, we have not found detailed public statements from the forum's operators about the breach, as of September 25, 2026.

What Should You Do If You Were Affected?

If you had an account on ThisHabbo Forum, take these steps:

Change your password on the forum if you still use the site, and on any account where you reused that same password.

Prioritize your email account. If your forum password matched your email password, change the email password first, since email access can be used to reset other accounts.

Watch for phishing. Be cautious with emails that mention Habbo or the forum, especially those asking you to log in or verify details through a link.

Use unique passwords going forward. A password manager makes it practical to keep a distinct password for every account.

Enable two-factor authentication where services offer it, starting with your email and any financial accounts.

Because this breach is more than a decade old, the data is likely long circulated. The protective steps above remain worthwhile, particularly if you have carried old passwords forward over the years.
