WATERCLOUD_INFO Leak Puts 39,960 Accounts at Risk of Takeover

A leak does not need to hit the millions to cause serious harm. WATERCLOUD_INFO, a stealer log uploaded to Telegram back on July 6th, 2025, contained 39,960 records, a smaller number by dark web standards, but every single one represents an account that could be taken over right now.

Why This Is Dangerous

Account takeover is the direct, practical outcome of a leak like this. With working email and plaintext password pairs in hand, an attacker does not have to guess or brute force anything, they simply log in as you. From there they can lock you out by changing the recovery email, wich turns a simple leak into a full loss of account access.

What Was Exposed

• 39,960 total leaked records
• Email Addresses
• Plaintext Password
• URLs connected to each compromised login

Why This Matters

Smaller leaks like WATERCLOUD_INFO tend to get less attention publically, but they are often more targeted and thourough because the group behind them can focus effort on fewer accounts. That means a higher percentage of these 39,960 records may still be active and usable today.

How Stealer Log Breaches Work

This dump came from the usual source, infostealer malware quietly running on infected machines, scooping up saved browser credentials, cookies, and autofill data. Once collected, the stolen information gets bundled into a text file and shared on channels like the one where WATERCLOUD_INFO surfaced, often labeled with a date and line count for buyers to quickly judge its size.
