ThisHabbo Forum (thishabboforum.com) suffered a data breach in 2014 that exposed around 612,414 accounts. If you had an account, some of your personal data may be circulating in leaked databases. The fastest way to know is to check your own email — free, in about 30 seconds, no password required.
What happened
In 2014, the ThisHabbo forum (a fan site for Habbo.com, a Finnish social networking site) appeared among a list of compromised sites which has subsequently been removed from the internet. Whilst the actual date of the exploit is not clear, the breached data includes usernames, email addresses, IP addresses and salted hashes of passwords. A further 584k records were added from a more comprehensive breach file provided in October 2016.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the ThisHabbo Forum breach exposed and what each item actually enables:
What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Passwords
Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else. - Names and usernames
Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts. - Email addresses
Treat any message referencing this service with suspicion, and never act on links in unexpected emails. - IP addresses
No direct action needed, but be wary of anyone quoting your location as “proof” of identity. - Confirm you were actually in it
Run a free scan before you spend time on the steps above.
How urgent is this now?
This breach is over 12 years old. Old credentials still cause harm — leaked passwords from a decade ago are still tried against new accounts every day.
Passwords are the reason breach age matters less than people expect. Leaked credentials are compiled into wordlists that get tried against new services for years afterwards, so a password exposed here is unsafe to use anywhere, ever again.
Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
