The ‘X1862 HQ Mix’ Combolist Quietly Surfaced With 1,856 US Logins

1,856 US Logins Quietly Surface in the "X1862 HQ Mix" Combolist

On July 21, 2026, HEROIC analysts spotted a combolist labeled "X1862 HQ MIX" that had been uploaded to a Telegram channel with little fanfare. The file contained 1,856 records combining email addresses with plaintext passwords and the URLs of the accounts they belong to, tied to United States users.

Why a Quiet Leak Like This Is Still Dangerous

Files like "X1862 HQ MIX" rarely make headlines, but that does not make them any less usable. The "HQ" in the name signals the passwords have been marked high quality, meaning they are believed to still be active. With plaintext passwords and matching URLs, an attacker can log into these accounts directly, with no extra effort required.

What Was Exposed in the 1,856-Record "X1862 HQ Mix" File

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

Why This Quiet Leak Still Puts People at Risk

Combolists like this one feed credential stuffing attacks, where automated tools try each email and password pair on other websites. Because so many people reuse passwords, a single leaked combo can open the door to account takeover, identity theft, and financial fraud long after the original leak goes unnoticed.

How "Mix" Combolists Like This One Are Put Together

A "mix" combolist blends login data pulled from multiple sources, such as older breaches, stealer malware, and phishing pages, into one combined file. The result is a broader set of credentials than a single-source dump, which is part of why sellers label these files "HQ," or high quality. Once compiled, the mixed list is shared quietly on Telegram, where it can spread before most people even notice it exists.

Check If Your Login Was Part of the "X1862 HQ Mix" Leak

Because leaks like this one tend to circulate quietly, it is worth checking proactively rather than waiting for a warning sign. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, so you can quickly see if your email address was part of this mix and update any passwords still in use.
