Hotmail TXTVALID Breach: 657 Accounts From One Stealer Log

In April 2026, a stealer log labeled Hotmail TXTVALID appeared after being uploaded to a Telegram channel by an anonymous user. The file contained 657 records pulled straight from infected computers, including email addresses, plaintext passwords, and the URLs of the sites those logins belonged to. HEROIC verified the exposure on 23-Apr-2026.

Why 657 Accounts From One Stealer Log Is a Big Deal

A stealer log this size did not come from a single hacked website. It was assembled from malware infections on hundreds of individual devices, then combined into one file and shared on Telegram, where criminals routinely trade fresh credentials. Because every password in the file is stored in plaintext, all 657 accounts can be accessed immediately by anyone who gets a copy, with no extra work needed to crack or decode anything.

What Was Exposed in the Hotmail TXTVALID Log

• Email addresses
• Plaintext passwords
• URLs of the websites and services those passwords unlock

Each entry links a working password directly to the site it opens, which means the log functions less like stolen data and more like a ready-made access list for 657 different accounts.

Why This Matters If You Are One of the 657

Stealer logs shared on Telegram rarely stay in one place. They get copied, resold, and loaded into automated tools within days, which creates several concrete risks:

• Credential stuffing: criminals test each email and password pair against banking, shopping, and social media sites, betting on password reuse.
• Account takeover: with the exact login URL included, an attacker can go straight to the right site and sign in as the victim.
• Identity theft: a compromised inbox often leads to password resets across other accounts, exposing more personal details.
• Financial fraud: if any linked site touches payment or banking information, stolen logins can turn into direct financial loss.

How a Stealer Log Like This Gets Built

Stealer malware usually spreads through cracked software, pirated games, or fake downloads. Once it lands on a device, it quietly scans the browser for saved usernames, passwords, and the web addresses they were entered on. The malware sends everything back to whoever is running it, and the results get bundled into a single file, in this case one covering 657 accounts, and shared or sold, here through a Telegram upload.

Check If You Are Affected

If you have ever saved a password in your browser or reused a login across more than one site, it is worth finding out whether your details are part of this or another exposure. HEROIC's free breach scanner checks a database of more than 400 billion leaked records, including stealer logs like this one, and tells you instantly if your email shows up.
