Was your data in the Teracod breach?

2016 · teracod.org · ~97,151 accounts exposedCritical severity · 10/10

Teracod (teracod.org) suffered a data breach in 2016 that exposed around 97,151 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 May 2015, almost 100k user records were extracted from the Hungarian torrent site known as Teracod. The data was later discovered being torrented itself and included email addresses, passwords, private messages between members and the peering history of IP addresses using the service.

What was exposed, and why it matters

Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Teracod 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.

Payment or bank details

Direct financial fraud, plus convincing scam calls that quote your real card or account details to establish trust.

Private messages

Personal correspondence can be used for blackmail or social engineering, and often contains other sensitive details you have forgotten sharing.

Names and usernames

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

Email addresses

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.

IP addresses

Reveals your approximate location and internet provider, which adds credibility to targeted scams.

Also listed in this breach: Avatars, Email addresses, IP addresses, Passwords, Payment histories, Private messages, Usernames, Website activity.

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. Payment or bank details: Contact your bank, ask them to monitor or reissue the card, and check statements for small “test” transactions.
  3. Private messages: Consider what was discussed on this service and whether anything needs changing (shared passwords, personal disclosures).
  4. Names and usernames: Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
  5. Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
  6. 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 10 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.
