MyRecon OSINTALIEN TXTBASE Stealer Logs
On 15 February 2025, ALIEN TXTBASE Stealer Logs was breached. 284,132,969 accounts were exposed, including email addresses, passwords. MyRecon rates it 84/100 — critical. That is roughly everyone in Brazil.
This is not a company's breach and reading it as one gets the response wrong. Stealer logs come from malware running on individual people's own computers, recording credentials as they are typed. If your address appears here, no service failed you. A machine you used was infected, and everything entered on it during that period should be assumed captured.
What makes a stealer log more dangerous than an ordinary credential dump is the third column. A leaked password list tells an attacker a password you once used. A stealer log tells them the password, the website it was entered into, and the email address that goes with it — a working login rather than a guess. Credential stuffing becomes unnecessary when the file already says where the key fits.
So the action here is different from every other entry in this archive. Changing one password is not the fix. Clean the device first, because otherwise the new password is captured too, then rotate credentials starting with email and anything financial.
What happened
In February 2025, 23 billion rows of stealer logs were obtained from a Telegram channel known as ALIEN TXTBASE. The data contained 284M unique email addresses alongside the websites they were entered into and the passwords used. This data is now searchable in HIBP by both email domain and the domain of the target website.

Who was behind it
No party has been publicly confirmed as responsible, and this page will not name one. Most breaches are never formally attributed: data surfaces on a forum or inside a combined dump long after the intrusion, and the trail back to a specific actor is rarely made public. Where a group has claimed responsibility it is usually named in the account above — that claim is theirs, not a finding of ours. These records came from information-stealing malware on victims' own machines rather than from one company's servers, so the exposure follows the person, not the site.
What was exposed, and why it matters
- Email addressesThe address becomes a confirmed, active target — expect more phishing, better aimed.
- PasswordsAnyone reusing this password elsewhere has those accounts exposed too — credential stuffing is automated and tries them all within days.
What to do if you were in it
- Change this password anywhere you reused it, starting with your email account — that is the one that can reset all the others.
- Expect better-aimed phishing. A message that already knows your name and where you have an account is the whole point of a breach like this.

Three kinds of content appear on this page and they are kept apart deliberately. The breach description is quoted from Have I Been Pwned under its licence. The severity score, the field-by-field explanation and the advice are computed from the record itself — every sentence derives from a number or a flag in it, which is what stops the analysis drifting from the evidence. Anything under the "MyRecon's take" byline is editorial: our reading of this breach, presented as opinion rather than as a finding.
