No Alarms Raised: Cloud_Rolex Log Exposed 45,777 Passwords

HEROIC analysts identified a stealer log dataset labeled Cloud_Rolex, uploaded to a public Telegram channel on December 29, 2025. There was no headline, no press release, just a quiet file upload containing 45,777 records, each pairing an email address with a plaintext password and a URL showing which site the login belongs to. That quiet is exactly what makes stealer logs like this one so easy to miss until the damage is already done.

Why This Is Dangerous

Nothing about this leak needs to be cracked or decoded. The passwords are plaintext, usable the moment someone opens the file, and the attached URLs tell an attacker exactly which website each credential unlocks. There is no noisy breach announcement to alert anyone that something is wrong, which means the tens of thousands of people in this file may have no idea their login information is circulating until an account is already compromised.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

At 45,777 records, this is a sizable list for a single stealer log. Because each entry already includes the exact site a credential works on, an attacker can skip the guesswork of credential stuffing and go straight to logging in, whether that account guards an inbox, a bank, or a shopping profile. A single successful login can snowball into account takeover, identity theft, or direct financial loss, and it can happen quietly enough that the victim only notices after the fact.

How Stealer Log Breaches Work

A stealer log is created when information-stealing malware infects a device and silently copies saved passwords and browsing activity in the background, all without the victim seeing anything unusual happen. Every account the person logged into while infected ends up bundled into the same file, which is why a log like this one likely contains credentials for dozens of unrelated websites rather than one company's customers. These logs are then uploaded to Telegram channels or cybercrime marketplaces, exactly like this Cloud_Rolex file, and quietly change hands among people looking for working logins.

Check If You Are Affected

A quiet leak is still a real leak. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, so you can check whether your email or passwords have surfaced and change them before anyone else has the chance to use them.
