The Redline_Cl0ud4 Dump Contains Exactly 53,517 Login Pairs

What HEROIC Analysts Found

In July 2026, HEROIC analysts identified a combolist file labeled "55K Fresh Mix Valid Redline_Cl0ud4," uploaded to a Telegram channel. HEROIC verified the file contains exactly 53,517 records pairing email addresses with plaintext passwords, along with the URLs of the sites those logins belong to.

Why This Is Dangerous

The file's name references Redline, a well-known password-stealing malware family that infects devices and harvests saved logins. Being labeled "fresh" and "valid" means the credentials were likely checked recently and confirmed to still work, making this list more dangerous than an older, unverified batch.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each login to the site it belongs to

Why This Matters

Credentials pulled from RedLine-style infostealer infections tend to include whatever was saved in a victim's browser, which often spans email, shopping, banking, and social accounts. Because a single infected device can hand over dozens of saved logins at once, and because passwords are so frequently reused, this file could open the door to multiple accounts belonging to the same person through credential stuffing.

How Combolists Work

A combolist is a compiled file of email or username and password pairs, often gathered from stealer logs like those produced by Redline, then merged and labeled by sellers as "fresh," "valid," or "mix" to describe how recent and reliable the credentials are. Buyers run these lists through checker tools to confirm which logins still grant access before using or reselling them.
