15,197 Passwords From WATERCLOUD_INFO Just Surfaced on the Dark Web

HEROIC analysts catalogued a stealer log dataset in July 2025 uploaded to a Telegram channel under the label WATERCLOUD_INFO - 115911 LINES 09.07.2025. The file contained 15,197 records with email addresses, plaintext passwords, and URLs. The filename indicates the raw log contained 115,911 lines before processing -- the 15,197 final records represent the filtered credential pairs extracted from that raw output. This is a common infostealer workflow: raw device data is collected, cleaned, and distributed in a smaller, more usable file.

Why a 15,197-Record Stealer Log Is Still a Meaningful Threat

Scale can be misleading when it comes to stealer logs. Smaller files like this one often contain credentials that are more recent and more likely to still be active -- they have not been sitting in a backlog for months waiting to be released. The WATERCLOUD_INFO dataset was uploaded on July 9, 2025, suggesting the underlying device infections were recent. Plaintext passwords mean attackers can use them immediately. The URLs make targeting eficiant. Even with just over 15,000 records, a motivated attacker can cause significant damage to individual victims through account takeover, email compromise, and finanical fraud.

What the WATERCLOUD_INFO Stealer Log Exposed

Each of the 15,197 records in this dataset contained:

• Email addresses (the login identifiers for affected accounts)
• Plaintext passwords (unencrypted, captured directly from infected devices)
• URLs (the specific services where each credential was captured)

The raw line count of 115,911 visible in the filename suggests the original device data was extensive. The 15,197 extracted records represent the credential pairs that survived the cleaning and filtering process.

Why the WATERCLOUD_INFO Leak Exposes You Across Multiple Platforms

Infostealer logs capture credentials in context -- meaning the URL field tells attackers exactly which platform each email and password combination was used on. When combined with the high rate of password reuse among internet users, that context makes a small log like this extremely valuable. A credential captured on one site can be tested against dozens of others. If the same password protects an email account, that becomes the master key -- enabling password resets on banking apps, shopping accounts, and subscription services. WATERCLOUD_INFO, small as it is relative to some datasets, represents real credential exposure for 15,197 people.

How WATERCLOUD_INFO Stealer Logs Are Generated and Cleaned

The WATERCLOUD naming convention and the presence of a line count in the filename are characteristic of infostealer log processing pipelines. Raw infostealer output from infected devices can include massive amounts of data -- browsing history, cookies, form data, screenshots, and more. The credential extraction step isolates email-password-URL triplets from that raw data. The line count in the filename (115,911) reflects the raw file size before extraction; the final record count (15,197) is after filtering for valid credential pairs. This processed file was then uploaded to Telegram under the WATERCLOUD_INFO channel or handle for distribution to criminal audiences on July 9, 2025.

Check Whether Your Email Appeared in the WATERCLOUD_INFO Leak

HEROIC's breach database contains over 400 billion compromised records, including stealer logs like WATERCLOUD_INFO. You can search your email address for free to find out whether your credentials were part of this exposure or any of the thousands of other datasets we index. If your email is found, change the password on every affected account immediately, then audit any other account where you used the same password. Enabling two-factor authentication on your email account is the most important single action you can take to limit access to your accounts even if your password is already known to an attacker.
