Hotmail Stealer Log: 13.3K Compromised Accounts

In June 2025, a stealer log containing 13,295 compromised Hotmail account credentials appeared on Telegram. This dataset includes plaintext email addresses, passwords, and associated URLs from an infostealer malware campaign targeting Hotmail users. The breach occured just months before being disclosed publicly.

Why This is Dangerous

Hotmail is one of the oldest and most widely used email services globally. A breach affecting 13,000+ accounts poses immediate risk to anyone using Microsoft email for account recovery across other platforms. Attackers gaining Hotmail access can reset passwords on linked services and drain associated accounts.

What Was Exposed

• Hotmail Email Addresses (13,295 records)
• Plaintext Passwords
• URLs and Login Details

Why This Matters

Compromized email accounts are the master key to digital identity theft. Once attackers control your Hotmail address, they can access any account using that email for recovery or verification. This single breach can cascade into total account takeover across your entire digital footprint.

How Email Stealer Malware Works

Infostealer malware captures credentials as they're typed or stored in browsers. When someone logs into Hotmail, the malware grabs the email-password pair along with any saved data. Users often don't know they're infected until their stolen credentials surface months later on Telegram or the dark web.

Check If Affected

If you used Hotmail in mid-2025, check if your email appears in this breach dataset. If affected, change your password and enable passwordless sign-in or strong two-factor authentication immediately.
