Hotmail Users Targeted in the HQ Hotmail Combo Neo3690 Leak

On 07-Jan-2025, HEROIC analysts identified a combolist named "HQ Hotmail Combo Neo3690" after it was uploaded by a Telegram user. The file is built specifically around Hotmail accounts and contains 9,307 records pairing email addresses with plaintext passwords and associated login URLs. Why This Is Dangerous Because this file focuses exclusively on Hotmail logins, attackers already know exactly which service each stolen credential unlocks. With the passwords stored in plaintext, there is no cracking involved: an attacker can plug each email and password directly into Hotmail's login page. A compromised Hotmail inbox is a serious problem since it is often the recovery address for banking, shopping, and social media accounts. What Was Exposed Hotmail email addresses Plaintext passwords Associated login URLs Why This Matters Hotmail and Outlook users are a frequent target for this kind of combolist because a working email login opens the door to password resets on nearly every other account tied to that address. Attackers run the 9,307 email, password, and URL combinations through automated tools to confirm which credentials still work, then use the valid ones for account takeover, identity theft, or financial fraud. How a Hotmail-Focused Combolist Is Built A combolist is a plain text file of email and password pairs, usually pulled from older breaches, phishing pages, or malware-infected devices and then repackaged for resale or free distribution. Files labeled "HQ" (high quality) and targeted at a single provider, like this Neo3690 Hotmail combo, are typically filtered and cleaned from larger mixed collections because single-provider lists sell for a premium on Telegram. Check If You Are Affected With 9,307 Hotmail accounts exposed in this leak, it is worth checking whether your email address is included. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, and tells you immediately if you have been exposed.
