WATERCLOUD_INFO Stealer Log: Someone Could Be In Your Accounts

HEROIC analysts identified the WATERCLOUD_INFO stealer log file on a private Telegram channel in July 2025. The archive was labeled with a collection date of July 5, 2025, and contained 10,655 records of email addresses, plaintext passwords, and URLs captured from infected devices. Each record represents a real person whose login session was silently intercepted by malware and packaged for distribution to cybercriminals before they had any chance to respond.

Why This Is Dangerous

The WATERCLOUD_INFO file is a stealer log, which means the passwords were not stolen from a company database. They were captured directly from people's computers as they typed them. Every password in this file is plaintext -- exactly as the victim typed it, with no encryption to slow an attacker down. Paired with the email address and the URL of the website where it was used, each record hands an attacker everything they need to walk directly into that account. And because most people reuse passwords, a single compromised login from this file can open doors to email, banking, social media, and cloud storage simultaneously.

What the WATERCLOUD_INFO Stealer Log Exposed

• Email addresses used as account logins across real websites
• Plaintext passwords captured in real time from browser sessions
• URLs identifying the specific platforms where each credential was stolen

Although 10,655 records is smaller than many stealer log releases, each entry is a complete, immediately actionable credential set. Attackers do not need to do any additional work -- the URL tells them where to use it, the email tells them who the account belongs to, and the plaintext password tells them how to get in. Every single record in WATERCLOUD_INFO represents a real compromised account.

Why Stealer Log Victims Face Immediate Account Takeover Risk

When a file like WATERCLOUD_INFO is shared in a Telegram channel, it reaches active threat actors within minutes. These actors run automated credential stuffing tools that test each email and password pair against the listed URL and, if that fails, against popular platforms the victim likely also uses. When a login succeeds, the attacker catalogs what they find: saved payment methods, personal information, contacts, and connected accounts. The documented outcomes of this type of breach include identity theft, unauthorized financial transfers, account hijacking, and phishing campaigns launched against the victim's own contacts using the compromised email address. The WATERCLOUD name suggests this file was part of a specific campaign targeting users of cloud-based platforms and web services.

How WATERCLOUD_INFO Stealer Logs Are Created

Stealer logs like WATERCLOUD_INFO are produced by information-stealing malware that infects victim devices through phishing emails, fake software downloads, malicious browser extentions, or cracked application installers. Once running, the malware operates invisibly in the background. It reads credentials saved in the browser, intercepts login keystrokes, and captures the URL of every site the user logs into. This data is bundled into a structured log file and transmitted to the attacker's server. The logs are then sorted, filtered, and uploaded to private Telegram channels for distribution. The date stamp in the WATERCLOUD_INFO filename (05.07.2025) indicates the collection occured on July 5, 2025 -- and the file was shared almost immediatly afterward, giving victims no time to react.

Check If Your Accounts Were Exposed in the WATERCLOUD_INFO Breach

Stealer logs shared on Telegram rarely appear in standard breach notification tools. HEROIC monitors private Telegram channels and dark web forums directly, indexing files like WATERCLOUD_INFO into a searchable database of more than 400 billion exposed records. A free search at HEROIC using your email address will tell you instantly whether your credentials were among the 10,655 captured in this file -- and whether you appear in any of the thousands of other breaches in our database. If your email shows up, you'll know exactly what to change and why.
