Data Troll Stealer Logs data breach: 109.5M accounts exposed
Severity: critical · Patch status: no-fix-needed · Since 2025-08-13
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. Exposed data: email addresses, passwords. The breach dates from Jun 20, 2025; Have I Been Pwned loaded it on Aug 13, 2025.
What to do
- If you had a Data Troll Stealer Logs account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
