Search Your Inbox: 1,141,419 Corporate Logins Leaked in Combolist

HEROIC analysts identified a dataset, tracked as COMBOLIST 1.3M CORPS FRESH 100, that a Telegram user uploaded on 14-Nov-2025. HEROIC's count shows 1,141,419 records, including email addresses, plaintext passwords, and the login page URLs tied to those accounts. The naming indicates this combolist was compiled to target corporate email accounts specifically.

Why This Is Dangerous

A combolist built around corporate accounts is especially valuable to attackers because business email logins often unlock internal systems, shared drives, and communications with coworkers, vendors, and customers. With 1,141,419 records in this file, an attacker running automated tools could gain a foothold in a large number of organizations at once.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Because corporate email often connects to other business tools, a single compromised login in this file could lead to credential stuffing across an organization's other services, account takeover, and in more serious cases financial fraud or identity theft for the individuals involved.

How Combolists Work

A combolist is built by combining email and password pairs from multiple sources, often older breaches, stealer log malware, and previously leaked databases, then merging and cleaning them into one large file. Sellers label combolists by target audience, size, and freshness, as seen here with a batch aimed at corporate accounts and marked "fresh," before sharing them through channels like Telegram.
