stealthcloudinfo Leak: What Hackers Can Do With 1.1M Passwords

stealthcloudinfo Stealer Log Uploaded to Telegram

HEROIC analysts found a large stealer log, labeled stealthcloudinfo, uploaded to a Telegram channel on 23 July 2026. The file contains 1,114,332 records pulled straight from infected devices, pairing email addresses and plaintext passwords with the exact URLs of the accounts they unlock. At over a million entries, this is one of the larger stealer log dumps HEROIC has tracked recently, and its size alone makes it attractive to criminals looking for large batches of working logins.

Why This Stealer Log Is Dangerous

What an attacker can do with this data is simple and immediate: take the email, password, and URL from any single record, plug them into the matching login page, and gain access to that account without any guessing or cracking required. Because the passwords are stored in plaintext and already matched to the correct site, criminals can automate this process across all 1,114,332 records in a matter of hours, testing each one and keeping whatever still works.

What Was Exposed

• Email addresses tied to individual accounts
• Plaintext passwords for those accounts
• URLs identifying exactly which websites the credentials belong to

Why This Matters

The scale of this leak means account takeover is a real risk for anyone included in it, since the data gives attackers everything needed to log in directly. It also raises the risk of credential stuffing: because people often reuse the same email and password across multiple sites, a working login found in this log could unlock other unrelated accounts, including email, banking, or shopping profiles that weren't part of the original infection.

How Stealer Logs Work

Stealer logs are produced by malware that infects a device, usually through a pirated download, a fake update, or a malicious attachment, and then quietly collects saved passwords and browsing data straight from the browser. The malware bundles this information, including which website each password belongs to, into a single log file. That file is then shared or sold, often on Telegram channels like the one where this dump appeared, giving buyers instant access to large volumes of ready-to-use credentials.

Check If You Are Affected

With over a million records involved, there's a real chance your information is among them. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out quickly and know which passwords to change.
