Researchers Link Cloud_Rolex to 12,905 Stolen Login Credentials

HEROIC analysts traced a stealer log named "Cloud_Rolex" to a public Telegram channel where it surfaced on July 29, 2025. The file contained 12,905 records, including email addresses, plaintext passwords, and the API host URLs tied to each account, with most exposed users located in the United States.

Why This Is Dangerous

Every password in this log was captured in plaintext, so it works the moment someone downloads the file, with no cracking or guessing required. Pairing plaintext passwords with the API host URL for each account gives an attacker both the credential and the exact address it unlocks, turning a simple list into a ready-made script for breaking into real accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• API host URLs

Why This Matters

A leak of nearly 13,000 records is more than enough to fuel credential stuffing attacks, where stolen email and password pairs are tested automatically against banking sites, email providers, and social media accounts. Anyone who reused one of these 12,905 passwords elsewhere is at risk of account takeover, which can quickly escalate into financial fraud or identity theft.

How a Stealer Log Like Cloud_Rolex Gets Made

Stealer logs come from infostealer malware that infects a device, often through a malicious download or cracked software, and silently copies every saved password, cookie, and autofill entry it finds. The malware bundles the results into a single file and sends it back to whoever controls it. From there, logs like Cloud_Rolex are shared for free or sold on Telegram channels and dark web forums, where anyone can download them and start testing the credentials inside.

Check If You Are Affected

There is no way to know just by looking whether your email address is part of a stealer log like this one. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records and tells you immediately whether your credentials have been exposed. Run a scan now and change any password that comes back compromised.
