Tiny Leak, Real Risk: PH136.158.116.128 Stealer Log Exposed

HEROIC analysts found a stealer log on a Telegram channel containing 2 records tied to an endpoint identified in the file as PH136.158.116.128. The data was uploaded on May 11, 2025, and includes an email address, a plaintext password, and a URL pulled directly from the infected device.

Why This Is Dangerous

A small record count does not mean small risk. Because the password in this log is plaintext rather than hashed, whoever holds the file can use it immediately, no cracking or guessing required. The URL included alongside it gives an attacker a direct hint at where that login might work.

What Was Exposed

• 2 individual records
• Email address
• Plaintext password
• URL
• Data first observed: May 11, 2025
• Origin: United States

Why This Matters

Even one exposed plaintext password is enough to cause real damage if it is reused anywhere else. Attackers routinely test small, precise leaks like this one against email providers, banking sites, and other accounts through credential stuffing, because a single working login is all it takes to start account takeover or financial fraud.

How Stealer Logs Work

A stealer log is generated by infostealer malware that infects a device and quietly copies saved browser passwords, autofill data, and visited URLs before sending it back to whoever controls the malware. Because the data is pulled straight from the browser, it comes out in plaintext instead of the hashed form a legitimate service would normally store. Even small logs like this one are packaged and shared on platforms like Telegram, exactly where HEROIC researchers found this one.

Check If You Are Affected

Small leaks are easy to overlook, but they still put real people at risk. Run a free check with HEROIC's breach scanner to see if your information is included. It searches a database of more than 400 billion leaked records to show you instantly whether you have been exposed.
