Data Troll Stealer Logs suffered a data breach in 2025 that exposed around 109,532,219 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 2025, headlines erupted over a "16 billion password" breach. In reality, the dataset was a compilation of publicly accessible stealer logs, mostly repurposed from older leaks, with only a small portion of genuinely new material. HIBP received 2.7B rows containing 109M unique email addresses, which was subsequently added to the service under the name "Data Troll". The websites the stealer logs were captured against are searchable via the HIBP dashboard.

What was exposed, and why it matters
Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Data Troll Stealer Logs 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.
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.
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.
- Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
- 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 recent, so the data is actively traded and the risk is at its highest right now.
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.
