3K Hotmail Leak Puts 3,129 Accounts at Risk of Takeover

In June 2026, HEROIC analysts identified a stealer log named "3K Hotmail 30.06" uploaded to a Telegram channel by a user distributing malware harvested credentials. The verified file contained 3,129 records, each pairing a login URL, an email address, and a plaintext password tied to Hotmail accounts.

What Happens Next If This Data Is Used

If a criminal picks up this log and tries the 3,129 leaked passwords against the matching Hotmail accounts, a successful login opens the door to reading private emails, resetting passwords on other linked services, and locking the real owner out of their own inbox. From there, the consequences can extend to drained accounts, unauthorized purchases, or a stolen identity used to open new credit lines.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• Associated Login URLs

Why This Matters

The consequences of this leak depend entirely on password reuse. Anyone among these 3,129 accounts who used the same Hotmail password on a bank, shopping site, or social media account faces a direct path to credential stuffing, account takeover, and financial fraud.

How Stealer Logs Work

Stealer logs are created by malware that infects a device and copies saved browser passwords before sending them to an attacker. Logs like this one, dated and labeled by the day they were harvested, are typically shared quickly on Telegram while the credentials are still fresh and most likely to work.

Check If You Are Affected

HEROIC's free breach scanner searches more than 400 billion leaked records, including stealer logs like this one. Scan your email address now to see if you are one of the 3,129 people exposed, and change any password that shows up as compromised.
