MAIL ACCESS 2K HOTMAIL USA VALID 100: 1,927 Accounts Leaked

In September 2025, HEROIC analysts identified a combolist labeled "MAIL ACCESS 2K HOTMAIL USA VALID 100" circulating on Telegram that exposed 1,927 records containing email addresses, plaintext passwords, and the URLs tied to each account. The name itself signals the contents: a batch of Hotmail accounts belonging to US users, marketed as verified and working.

Why This Is Dangerous

Because every password in this file is stored in plaintext, an attacker does not need to crack or decode anything before logging in. The "valid" label in the file name also suggests these credentials have already been tested, meaning the 1,927 records here are more likely to be working logins right now rather than outdated leftovers from an old breach.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each account

Why This Matters

Nearly 2,000 US Hotmail accounts in one file is enough to fuel serious credential stuffing activity. If any of these email and password combinations are reused on other sites, attackers can use them for account takeover, and from a compromised inbox, reset passwords on banking, shopping, or social media accounts, leading to identity theft and financial fraud.

How This Combolist Was Built

Combolists like this one are assembled by pulling email and password pairs from sources such as phishing pages, malware infections, or older leaks, then running automated checks against Hotmail to confirm which pairs still log in, labeling the working ones as "valid." Telegram makes it simple to package and share files like this, which is why targeted, verified combolists continue to circulate regularly.

Check If You Are Affected

If you have a Hotmail or Outlook account in the US, or reuse the same password across sites, it is worth checking now. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to show whether your email and credentials appear in this leak or any other, so you can secure your accounts before someone else does.
