Was your data in the Battlefield Heroes breach?

Battlefield Heroes (battlefieldheroes.com) suffered a data breach in 2011 that exposed around 530,270 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 June 2011 as part of a final breached data dump, the hacker collective "LulzSec" obtained and released over half a million usernames and passwords from the game Battlefield Heroes. The passwords were stored as MD5 hashes with no salt and many were easily converted back to their plain text versions.

What was exposed, and why it matters

Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Battlefield Heroes breach exposed and what each item actually enables:

Passwords

Attackers replay leaked passwords across other sites (“credential stuffing”). Because most people reuse passwords, one leak often unlocks email, shopping and banking accounts elsewhere.

Names and usernames

Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.

What to do if you were affected

These steps are ordered for this specific breach — the most urgent action given what leaked comes first.

  1. Passwords: Change this password everywhere you have reused it, starting with your email account — whoever controls your email can reset everything else.
  2. Names and usernames: Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
  3. Check whether your own email appears in this breach — run a free scan to confirm before you spend time on the steps above.

How urgent is this now?

This breach is over 15 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.
