Cloud_Rolex_4 Breach: 41,436 Passwords Leaked on Dark Web

HEROIC analysts logged a stealer log file named "Cloud_Rolex_4" uploaded to a Telegram channel on June 26, 2026. The file contained 41,436 records pulled straight from infected computers, each one pairing an email address with a plaintext password and the login URL it belongs to.

Why the Cloud_Rolex_4 Leak Is Dangerous

What sets a stealer log apart from most breaches is the format the data arrives in. There's no encryption to break through. The password sits in plain text, right beside the exact site it opens, so an attacker can move from download to login in minutes.

Because the file organizes credentials by URL, criminals can quickly filter for high value targets like banking portals or corporate email, rather then wading through unsorted data.

What Was Exposed: The Cloud_Rolex_4 Data

• Email addresses
• Plaintext passwords
• Associated login URLs

HEROIC's research team verified all 41,436 records before this incident was added to our breach database.

Why This Matters: The Ripple Effect of Reused Passwords

A single password from this leak can open far more than one account if it has been reused elsewhere. That's the mechanism behind credential stuffing, where attackers automatically test stolen logins across dozens of popular sites. Once one login succeeds, account takeover, identity theft, and financial fraud usually follow close behind.

Complexity in a password doesn't help once the password itself has already been captured. The only real fix is changing it.

How Stealer Log Malware Works

Stealer malware typically arrives disguised as pirated software, a cracked game, or a fake update. Once active on a device, it quietly copies stored browser passwords, autofill entries, and session cookies, then bundles everything into an exportable log.

Those logs are then traded or leaked on Telegram channels and underground forums, wich is precisely how Cloud_Rolex_4 became public. Victims almost never notice the infection until damage is already done.
