StealthCloudInfo July 19 Leak: 290,209 Passwords Found Online

HEROIC Analysts Log a 290,209-Record StealthCloud Stealer Leak

On July 19, 2026, HEROIC's threat intelligence team observed a stealer log titled "stealthcloudinfo - 19-07-2026" appear on Telegram, containing 290,209 records made up of email addresses, plaintext passwords, and the login URLs tied to each account. The dated naming suggests this is one entry in an ongoing series of releases from the same source.

Why This Is Dangerous

A log of nearly 300,000 plaintext credential pairs gives an attacker an enormous head start. There is no password cracking involved, only a ready-made list of emails, passwords, and the exact sites each pair unlocks, available to anyone who obtains the file.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs (the exact pages the credentials unlock)

Why This Matters

At nearly 300,000 records, this leak is large enough to support serious credential stuffing campaigns across major websites. Analysts expect a meaningful share of these accounts to be vulnerable to takeover simply because password reuse remains so common, putting banking, email, and shopping accounts at risk well beyond the original login.

How Analysts Track Recurring Logs Like StealthCloudInfo

Sources that release logs on a recurring schedule, like this one dated 19-07-2026, are typically run by an operator continuously harvesting fresh infections and pushing out new batches every few days. HEROIC's monitoring watches for these recurring naming patterns to catch new leaks as soon as they surface, rather than after the data has already spread widely.

Check If You Are Affected

With hundreds of thousands of records in play, checking your own exposure takes only a moment. HEROIC's free breach scanner searches more than 400 billion breached and leaked records, so you can see whether your email appears in this log or any other and act before your credentials are used against you.
