Validated Hotmail Combolist: 882 Logins Fuel Account Takeover Risk

A "Valids" Hotmail Combolist Circulates on Telegram

In March 2026, HEROIC analysts found a combolist labeled "VALIDS HOTMAILS" uploaded to Telegram, containing 882 records of email addresses and plaintext passwords along with associated URLs. Labeling a list as "valids" signals to buyers that the credentials have already been tested and confirmed to still work, making this file more dangerous than an unverified dump.

Why a "Validated" List Raises the Stakes

Most stolen credential lists mix working logins with dead ones, but a "valids" list has already been checked, meaning every one of these 882 email and password pairs is more likely to log in successfully right now. That single working login can chain into further damage: once inside a Hotmail inbox, an attacker can trigger password resets on other accounts tied to that email, turning one exposed password into a foothold across several services.

What Was Exposed

• Email addresses (Hotmail accounts)
• Plaintext passwords
• Associated URLs

Why This Matters

A validated combolist is a direct pipeline to account takeover, since attackers skip the trial-and-error of credential stuffing and go straight to logins they know work. From there, the risk chains outward fast: access to an email inbox often unlocks banking alerts, shopping accounts, and password reset links, opening the door to identity theft and financial fraud well beyond the original 882 records.

How Validated Combolists Are Made

Sellers build "valids" lists by running raw combolists or stealer log data through automated checker tools that attempt to log into each account and flag which credentials still work. The confirmed logins are then repackaged and sold or shared, as seen here, at a premium over unverified data, since buyers know every entry has a higher chance of actually granting access.

Check If You Are Affected

If you use a Hotmail account, especially one with a password you've reused elsewhere, it's worth checking whether your credentials appear in this or any other exposed list. HEROIC's free breach scanner searches more than 400 billion leaked records, giving you a fast way to confirm your exposure and change any passwords before they're used against you.
