What happened

In July 2018, the health and fitness service 8fit suffered a data breach. According to Have I Been Pwned, the data appeared for sale on a dark web marketplace in February 2019.

What was exposed

The data covers about 15 million unique email addresses, along with names and genders. Geographic locations and IP addresses leaked too. Passwords were stored as bcrypt hashes, a strong method that makes cracking slow, though a simple password can still fall.

What it means for you

A name, an email address and a rough location make a believable phishing message. Fitness gives scammers easy hooks, such as a renewal or a cancelled plan. The password risk is lower than with older hash types. It isn't zero.

Can the data be taken down?

No. Once a breach is copied and shared, nobody can pull it back, and the company can't either. What you control is how useful the data is to criminals: unique passwords, two-factor login and skepticism toward messages that quote your details. Serus monitors breach databases and the dark web for your email and phone and alerts you when your details appear in a new leak.

What to do

Change reused passwords and turn on two-factor login. Ignore fitness messages that push you to log in through a link.

What to do if you were in it

  1. 1

    Change your 8fit password, and any you reused

    If you used the same or a similar password on another account, change it there too. A password manager makes unique passwords easy.

  2. 2

    Turn on two-factor login

    Use an authenticator app or a passkey on your email and other important accounts. It blocks most takeovers even when a password is already out.

  3. 3

    Expect phishing that fits the data

    Expect emails about subscriptions, plans or refunds that use your name. Go to the app or site yourself instead of clicking.

  4. 4

    Check which other breaches include you

    Run a free Serus scan to see whether your email or phone number appears in this and other breaches. Serus monitors breach databases and the dark web and alerts you when your details show up again.
