What Attackers Can Do With the HQ USA Combo NEO3690 Leak

HQ USA Combo NEO3690 Leaks 14,679 Credential Pairs

HEROIC analysts identified a combolist named "HQ USA COMBO TEST NEO3690" that was uploaded to a Telegram channel on February 18, 2025. The file contains 14,679 records pairing email addresses with plaintext passwords, along with URLs tied to each entry.

Why This Is Dangerous

The words "HQ" and "TEST" in this file's name suggest it was marketed as a high quality sample batch, the kind sellers release to prove a larger combolist works before selling the full set. Whether or not that claim holds up, the 14,679 credentials inside are stored in plaintext, so anyone who downloads the file can use them immediately without cracking anything.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

With an email, password, and matching URL for each of the 14,679 records, an attacker can move straight to testing logins on the exact sites those credentials belong to, a technique known as credential stuffing. Anyone in this file who reused their password on other accounts risks having those accounts taken over too, which can escalate into identity theft or financial fraud once an attacker controls an email address.

What Attackers Can Do With This Combolist

Armed with 14,679 verified email and password pairs, an attacker can automate login attempts across banking sites, retail accounts, and email providers in minutes rather than days. Because each record already includes the URL the credentials were used on, there is no guesswork involved, the attacker simply feeds the list into a checker tool and lets it run. Any successful login can then be used to lock out the real owner, drain funds, or harvest more personal information for further attacks.
