Inside the Cloud_Rolex_3 Breach: How 2,831 Records Were Compromised

In November 2025, a Telegram user published a stealer log file labeled "Cloud_Rolex_3" that contained 2,831 records of harvested credentials. While the record count may seem small compared to larger leaks, each entry represents a real person whose email address, password, and associated URLs were exposed without their knowledge. The data was made freely available on Telegram, giving anyone who saw it immediate access to working login credentials.

Why This Is Dangerous

Even a smaller breach can cause outsized harm when the exposed data is this actionable. Plaintext passwords paired with email addresses are essentially turnkey account access kits. There is no need for any additional cracking or guessing, the credentials are ready to use the moment someone downloads the file.

The inclusion of API host URLs raises the stakes further. These are not just website logins but potential pathways into cloud services, developer environments, and backend systems. If any of the 2,831 people in this dataset used the same credentials for work accounts, the impact could extend well beyond a single compromised email.

Because this log was shared on a public Telegram channel, the data is no longer contained. It may have been downloaded, copied, and shared dozens of times before the channel was even noticed. Anyone who recieved a copy could run automated credential stuffing attacks against popular services at any time.

What Was Exposed

• Email addresses
• Plaintext passwords
• Website and service login URLs
• API host endpoint addresses
• Browser-autofilled credential pairs
• Application session data captured at the endpoint
• Service-specific login strings

Why This Matters

The naming convention "Cloud_Rolex_3" suggests this was not the first or second log in a series, meaning the person or group behind it has likely been publishing stealer log batches on a regular basis. Each new upload adds more exposed credentials to the pool available to attackers, and past uploads may still be circulating long after the channel goes quiet.

For the 2,831 people in this particular file, the risk is ongoing. Credential stuffing bots do not stop after one attempt, they cycle through large lists of email-password combinations repeatedly across hundreds of services. Even if one account holds up, another tied to the same credentials may not.

How Stealer Log Works

A stealer log is the output of infostealer malware running on a victim's device. The infection typically starts with something that looks harmless, like a pirated software installer, a fake game mod, or a document attached to a phishing email. Once the malware runs, it begins harvesting everything it can find saved in the browser, including passwords, cookies, and form data.

The harvested data gets packaged into a log file and sent back to the attacker's server, usually within minutes of the infection. The logs are then sorted, with high-value credentials seperately flagged for personal use, and the rest gets published or sold in bulk on platforms like Telegram.

What makes this attack type particularly difficult to detect is that it does not leave obvious signs. The device keeps functioning normally, the user does not recieve any warning, and the credentials start being used against other services long before anyone notices something is wrong.
