Researchers Link wm.com to 2,300 Exposed Login Credentials

wm.com Combolist: What HEROIC Analysts Found

In May 2026, HEROIC threat analysts identified a combolist tied to the wm.com domain, uploaded to a Telegram channel on 25 May 2026. The file contains 2,300 records, each pairing an email address with a plaintext password and the URL of the login page it unlocks. That is 2,300 working logins connected to one domain, all sitting in a single downloadable file.

Why This Is Dangerous

Every entry in this combolist is a ready-to-use login: an email, its plaintext password, and the exact site it opens, with no cracking or guessing required. An attacker can pull a line from the file and log in as the account holder in seconds. With 2,300 confirmed pairs to work through, criminals can automate login attempts across the entire list in minutes, filtering for the accounts most worth pursuing.

What Was Exposed

• Email addresses tied to the wm.com domain
• Plaintext passwords stored with no encryption
• URLs identifying the exact login page each credential unlocks

Why This Matters

A work email address is often tied to far more than internal systems, sometimes reused for banking, shopping, or personal accounts that were never updated. If any of these 2,300 people reused their password elsewhere, this combolist gives attackers a direct route into credential stuffing attacks, which can quickly escalate into account takeover, identity theft, or financial fraud well beyond wm.com itself.

How This wm.com Combolist Was Assembled

A combolist is built by pulling working email and password pairs from older breaches, malware-infected devices, or automated credential-checking tools, then organizing them into one ready-to-use file. Criminals value combolists because the verification work is already done, every pair has been confirmed to work or sourced from data known to be reliable. Files like this one circulate on Telegram, where anyone can download them and start testing the credentials against other sites within minutes.

Check If You Are Affected

If you have ever used a wm.com email address to sign up for an account, it's worth checking whether your details were part of this leak. HEROIC's free breach scanner checks your email against more than 400 billion leaked records to show you instantly whether your information has been exposed. If you find a match, change that password right away and avoid reusing it anywhere else.
