The 123.com Combolist Contains Exactly 4,487 Email Pairs

123.com Combolist Contains Exactly 4,487 Email and Password Pairs

HEROIC analysts identified a combolist titled "123.com - 4.487 emails," uploaded by a Telegram user on 10 June 2026. The file contains 4,487 records, each pairing an email address tied to 123.com with a plaintext password and the URL the credentials were used on.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who downloads it can read and use every one of the 4,487 credentials immediately, with no cracking or decryption needed. The precise count in the file's own title suggests it was carefully compiled and verified before being shared, which makes it more attractive to other criminals looking for working logins.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs

Why This Matters

Even though this leak is tied to a single service, the real danger extends further. If any of these 4,487 people reused their password on other websites, attackers can use this exact list to attempt credential stuffing against banking, email, and shopping accounts, turning one exposed password into multiple compromised accounts and potential financial fraud.

How a Combolist Like This Gets Compiled

Combolists organized around a single domain, like this 123.com file, are usually built by pulling credentials from stealer logs, phishing pages, or previous breaches, then filtering the results down to accounts tied specifically to that service. This makes the list easier to sell to buyers with a specific target in mind before it's shared on Telegram.

Check If You Are Affected

If you have an account associated with 123.com, or reuse passwords across different sites, it's worth checking your exposure now. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, so you can quickly see if your credentials appear in this leak or any other and change them before someone else does.
