A Quiet Leak: AlphaCloudAdmin Just Exposed 11,130 Passwords

No headlines, no press release, just a quiet upload to a public Telegram channel on November 21, 2025. HEROIC analysts identified a stealer log file called AlphaCloudAdmin 434count containing 11,130 exposed records, including email addresses, plaintext passwords, and the URLs of the accounts those credentials belong to, all harvested directly from infected devices.

Why This Is Dangerous

Leaks like this rarely make the news, but that does not make them any less dangerous. Because the passwords are stored in plaintext and matched to the exact login URL, anyone who finds this file can start using the credentials immediately, quietly and without drawing attention.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages and accounts

Why This Matters

A quiet leak can still lead to loud consequences. Anyone who reused a leaked password elsewhere is at risk of credential stuffing attacks and account takeover, and the linked email addresses give attackers what they need for identity theft and financial fraud, often long before the victim notices anything is wrong.

How Stealer Log Breaches Happen

Stealer logs like AlphaCloudAdmin 434count come from infostealer malware that infects a device through a phishing link, cracked software, or a fake installer. Once active, it scans the browser for saved logins and autofill data, then packages everything into a log tied to that machine. Criminals collect thousands of these logs and quietly upload or sell them in bulk, which is how this dataset reached the public without notice.

Check If You Are Affected

Quiet leaks can go unnoticed for a long time. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records in seconds, so you can find out before an attacker does.
