Hotmail Stealer Log Leak: What Hackers Do With 1,875 Logins

In June 2026, a Telegram user uploaded a stealer log dataset labeled “1.8K Hotmail 25.06,” containing 1,875 records of email addresses, plaintext passwords, and login URLs pulled directly from infected computers. Despite the Hotmail name in the file's title, this was not a breach of Microsoft's servers. It's a collection of Hotmail and Outlook account logins that malware stole from individual users' own devices, then packaged up and shared for free.

What Attackers Can Do With These Logins

Once a criminal has a working email address and its plaintext password, the first move is usually to log straight into the account and see what's inside. From there, an attacker can reset passwords on any other service tied to that inbox, from banking apps to shopping accounts, since email is the master key most password reset links go through. They can also mine years of old messages for anything usable: tax documents, past purchase confirmations, or answers to security questions.

What Was Exposed

• Email addresses (Hotmail/Outlook accounts)
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Because the passwords are stored in plain text, there's no cracking or guesswork involved for whoever downloads this file. A matching email and password combination can be used immediately for credential stuffing on other sites, account takeover of the inbox itself, or as a stepping stone into identity theft and financial fraud if the victim reused that password anywhere else.

How Stealer Logs Like This Get Made

Infostealer malware infects a device, often hidden inside a cracked program, fake software update, or malicious download, and then quietly copies every saved password, autofill entry, and cookie stored in the browser. The malware bundles this into a log file that gets uploaded to Telegram channels like the one this dataset came from, where it can be downloaded by anyone for free or resold in bulk.

Check If You Are Affected
