What happened
In July 2018, the health and fitness service 8fit suffered a data breach. The data subsequently appeared for sale on a dark web marketplace in February 2019 and included over 15M unique email addresses alongside names, genders, IP addresses and passwords stored as bcrypt hashes. The data was provided to HIBP by dehashed.com.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the 8fit breach exposed and what each item actually enables:
Also listed in this breach: Email addresses, Genders, Geographic locations, IP addresses, Names, Passwords.
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. - Location data
Review location sharing on the accounts you still hold with this service. - 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 8 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.
