5,777 Plaintext Logins Found in WATERCLOUD_NOTIFY’s 416 Files

HEROIC analysts recorded 5,777 plaintext email and password pairs inside a WATERCLOUD_NOTIFY stealer log batch of 416 files, dated 05 August 2024 and posted to a Telegram channel. Each entry was pulled directly from an infected device, complete with the exact login page it belongs to. Check your own exposure with a free scan your email lookup.

Why stolen device data carries extra risk

Malware harvested logins are different from an old database leak because the credentials were captured recently, straight from the browser of whoever was using the infected machine. That means the password is likely still the one the account owner is using today, not one they abandoned years ago.

What was exposed

• Email addresses mark real accounts that were logged into on a compromised device.
• Plaintext passwords are usable immediately, without any cracking step.
• URLs tell an attacker exactly which site each stolen password opens.

Why this matters

With 5,777 fresh, working credentials in circulation, the risk is not theoretical. An attacker who buys or downloads this batch can start logging into accounts within minutes, and because these come from active infections, success rates tend to run higher than with older, recycled leaks.

How this kind of stealer log gets made

Infostealer malware sits on an infected machine and quietly copies saved browser passwords, autofill data and the URLs tied to them, then sends the haul back to whoever is running the malware. The 416 files in this batch each represent one infected device, merged into a single release.

Ready to check if you were caught in this batch?

Run HEROIC's scan your email tool to see whether your address is one of the 5,777 exposed. If it is, reset that password immediately, run a malware scan on any device you think might be compromised, and check both your personal inbox and your work email since either can end up in a stealer log.
