If You Reuse Passwords, the Hotmail Hits Leak Should Worry You

HEROIC flagged a stealer log file titled "Hotmail Hits" that appeared on Telegram in December 2024. The file is small — 159 records — but each entry contains a Hotmail email address paired with a plaintext password and the URL where the credential was stolen. For the individuals whose data is inside, this leak represents a direct and immediate threat to every account connected to that email address.

Plaintext Means Your Password Is Already Compromised

There is no protective layer around the passwords in this file. They are stored as plain, readable text — not hashed, not encrypted. An attacker who downloads the Hotmail Hits file can begin using these credentials within seconds. No password-cracking tools are needed, no computing resources required. The 159 affected users should consider their current passwords fully compromised from the moment this file was shared.

What Was Exposed

• Email Addresses — Hotmail accounts that often double as Microsoft account logins
• Plaintext Passwords — unencrypted, immediately exploitable credentials
• URLs — showing which websites the malware captured each login from

Why Password Reuse Makes You the Ideal Target

If you use the same password for your Hotmail account and your online banking, shopping, or social media profiles, you are exactly the kind of target that credential-stuffing attacks are designed to exploit. Automated tools take each entry from a file like Hotmail Hits and test it across thousands of services. One match gives attackers a foothold. Multiple matches give them your entire digital life. The 159 accounts in this dump are 159 potential entry points into broader networks of compromised services.

How This Data Was Stolen by Infostealer Malware

The credentials in Hotmail Hits were captured by infostealer malware installed on victims' devices. These trojans — variants like Lumma, Stealc, and RedLine — silently extract saved passwords from browsers, harvest autofill data, and intercept login sessions. The stolen information is transmitted to attacker-controlled servers and later organized into targeted collections like this one, specifically filtered for Hotmail credentials, before being distributed to other criminals on Telegram.

Check If Your Credentials Were Exposed

Do not assume that a 159-record file is too small to contain your data. HEROIC's data breach scanner searches more than 400 billion compromised records, including small, targeted leaks like Hotmail Hits. A quick search can reveal whether your email or password appears in this or any other breach, giving you the opportunity to change compromised credentials before they are exploited.
