Was your data in the Android Forums breach?

Android Forums (androidforums.com) suffered a data breach in 2011 that exposed around 745,355 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 October 2011, the Android Forums website was hacked and 745k user accounts were subsequently leaked publicly. The compromised data included email addresses, user birth dates and passwords stored as a salted MD5 hash.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Android Forums breach exposed and what each item actually enables:
Attackers replay leaked passwords across other sites (“credential stuffing”). Because most people reuse passwords, one leak often unlocks email, shopping and banking accounts elsewhere.
Date of birth is a permanent identifier used to verify identity by phone. Combined with a name and address it is often enough to impersonate you.
Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.
Reveals your approximate location and internet provider, which adds credibility to targeted scams.
Also listed in this breach: Dates of birth, Email addresses, Homepage URLs, Instant messenger identities, IP addresses, 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.
- Dates of birth: Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
- 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.
- 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.
