WATERCLOUD_NOTIFY Stealer Log Exposed 485 Infected Users’ Logins

In July 2024, a Telegram channel released a stealer log file labeled "WATERCLOUD_NOTIFY-22.07.2024-525 FILES-THANKS FOR SUB," apparently shared as a bonus for channel subscribers. HEROIC analysts identified 485 records inside, each containing a compromised device's endpoint information, an email address, the site or API host it connects to, and the account's password.

Why This Is Dangerous

Stealer logs like this one come directly from malware that infected a victim's device and quietly copied saved passwords and login sessions from the browser. Because the data was pulled straight from an infected machine rather than recycled from an old breach, the credentials tend to be current and working, meaning the accounts tied to these 485 records were very likely still active and vulnerable at the time the file was shared.

What Was Exposed

• Email addresses
• Plaintext passwords
• Connected site and API endpoint URLs

Why This Matters

People whose devices are infected with stealer malware rarely know it happened until the damage is done. With working, current credentials in hand, attackers can log directly into email, banking, or work accounts without guessing or cracking anything, which speeds up account takeover, financial fraud, and identity theft compared to attacks that rely on older, recycled leaks.

How the WATERCLOUD_NOTIFY Stealer Log Was Likely Collected

Infostealer malware typically spreads through phishing emails, cracked software, or fake downloads. Once it lands on a device, it silently harvests every password saved in the browser, active login sessions, and details about the endpoints those accounts connect to, then packages everything into a "log" per infected machine. The "THANKS FOR SUB" wording in this file's name suggests it was handed out as a free sample to reward or attract subscribers to a Telegram channel that sells or trades stealer logs, a common tactic used to build an audience before charging for larger or fresher batches.

Check If You Are Affected

Because stealer logs contain live, working credentials, it's worth checking right away if your email address has turned up in this or any other breach. Run a free scan with HEROIC's breach checker, which searches more than 400 billion leaked records, and if you get a match, change the affected passwords immediately and run a malware scan on your devices.
