The Cyprus Corp Mail Dump Contains Exactly 1,056 Login Pairs

HEROIC analysts identified a combolist labeled "Cyprus Corp-Others-Pro Mails Test Sample" circulating on a Telegram channel in February 2026. The file paired 1,056 email addresses with plaintext passwords and the URLs of the sites those logins belong to, the standard format attackers use to automate login attempts across the web.

Why the Cyprus Corp Mail Combolist Is Dangerous

A combolist is not a puzzle an attacker has to solve. The passwords in this file were stored in plaintext, meaning anyone who downloads it can copy an email and password pair and try logging in immediately, no cracking or guessing required. When the URL field is included, the attacker also knows exactly which site or service each credential pair unlocks, which speeds up automated attacks even further.

The file's own name marks it as a test sample tied to corporate mail addresses, suggesting it was cut from a larger batch before being shared more widely on Telegram.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each credential pair to its original login page

Why This Matters

Anyone whose email and password appear in this file faces a real risk of credential stuffing, where automated tools feed leaked logins into hundreds of websites at once looking for a match. Because these addresses appear to be tied to corporate mail accounts, a successful login could expose more than one person's data, corporate email is often a gateway to shared drives, internal systems, and other employee accounts. If the password here has ever been reused elsewhere, that risk multiplies.

How Combolists Like This One Are Built

Combolists are compiled by merging credentials pulled from older breaches, phishing kits, and malware logs into a single searchable file, then formatted as email:password or email:password:URL so they can be fed straight into automated login tools. They are traded and sold cheaply on Telegram and dark web forums because they let low-skill attackers run large-scale login attempts with almost no technical effort. A file's age or small scope does not make it safe, every record represents a real account.

Check If You Are Affected

You do not have to guess whether your information is sitting in a dump like this one. HEROIC's free breach scanner checks your email address against more than 400 billion leaked records pulled from combolists, stealer logs, and dark web marketplaces. Run a free scan, and if a match turns up, change that password everywhere else you have used it.
