Malware Silently Stole These Wako_Cloud Login Credentials

Wako_Cloud Stealer Log: 12,107 Records of Emails, Passwords, and API Endpoints

On 11-Jul-2026, HEROIC analysts identified a stealer log named "Wako_Cloud" uploaded by a Telegram user. The file contained 12,107 records pulled directly from infected devices, including email addresses, plaintext passwords, and the URLs and endpoints those credentials belong to.

Why This Is Dangerous

Unlike a leaked database, a stealer log comes straight from malware running on someone's own computer, capturing exactly what that person typed or had saved in their browser. Because the passwords are plaintext and tied to the URL or API endpoint they unlock, an attacker can immediately log in as the victim on the real service, no cracking, no guessing.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs and API endpoints linked to each credential

Why This Matters

With 12,107 records in a single log, this file gives attackers a large batch of working logins to run through credential-stuffing scripts against email, cloud, and API-connected services. Anyone in this log who reused a password elsewhere faces a heightened risk of account takeover, identity theft, or financial fraud, especially since infostealer malware often captures other saved logins on the same device too.

How Stealer Logs Work

A stealer log is the output of infostealer malware that infects a device, usually through a fake download, cracked software, or phishing link, and then quietly harvests saved browser passwords, autofill data, and the URLs or API hosts tied to each one. That harvested data is bundled into a log file, sometimes labeled with a nickname like "Wako_Cloud," and uploaded to a Telegram channel or dark web marketplace where buyers pick through the credentials for accounts worth targeting.

Check If You Are Affected

If your email address turns up in the Wako_Cloud stealer log or any other leaked dataset, you deserve to know before someone else acts on it. HEROIC's free breach scanner checks your address against a database of more than 400 billion leaked records, so you can find out fast and lock down any exposed accounts.
