Inside the Cloud_Rolex_4 Stealer Logs: 12,809 Passwords Harvested

In late July 2026, HEROIC analysts identified a stealer log titled 'Cloud_Rolex_4' uploaded to a Telegram channel by an individual user. Unlike a typical combolist compiled from old breach data, this file was generated by malware running on infected computers, and it contains 12,809 records combining email addresses, plaintext passwords, and the URLs of the accounts those credentials unlock. Why This Is Dangerous: Stealer logs capture credentials directly from a victim's browser at the moment of infection, which means the data in this file reflects passwords that were actively in use, not old or already-changed ones. An attacker with this file can log into a victim's email, banking, or work accounts using details that were valid right up until the malware grabbed them. What Was Exposed: email addresses; plaintext passwords; associated login URLs. Why This Matters: With nearly 13,000 records, this file gives attackers a large, current set of working logins to try immediately, and because each entry includes the exact site a password belongs to, there's no guesswork involved in choosing where to use it. That makes stealer log victims especially vulnerable to fast account takeover and, potentially, financial fraud. How Stealer Logs Work: Stealer malware infects a device, often through a fake download, pirated software, or a malicious attachment, and then silently collects saved browser passwords, autofill details, and session data before sending it all back to whoever controls the malware. The result gets organized into a file like 'Cloud_Rolex_4,' likely named after the malware family or campaign, and then sold or shared on Telegram. Check If You Are Affected: If your device has ever picked up credential-stealing malware, your saved passwords could be sitting in a file exactly like this one. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including stealer logs, so you can reset any exposed password before someone else uses it.
