12KYAHOO TAIWAN Leak Contained Exactly 11,628 Login Records

Not 12,000. Not "about" 12,000. The file called 12KYAHOO TAIWAN, uploaded to Telegram on June 17, 2025, held exactly 11,628 individual login records, a small but precise detail that matters more than it might seem.

Why This Is Dangerous

Precision like this usually means someone counted carefully before selling the file, which suggests the credentials inside have already been checked and are more likely to be current and working. That makes all 11,628 records more dangerous than a rougher, unverified estimate would suggest.

What Was Exposed

• Email addresses gathered from infected systems
• Passwords recorded in plaintext, unprotected
• URLs tied to the exact login page for each credential

Why This Matters

The name references Yahoo and Taiwan, which suggests this batch was pulled together or filtered around accounts tied to that service or region. Many people never relize their old Yahoo-linked credentials were still active anywhere at all. Whatever the exact sorting method, all 11,628 people in the file face the same basic risk.

How a Stealer Log Gets This Specific

Malware operators often sort their harvested logs by keyword, service name, or region before selling them, which is likely how a batch got labeled with both a service reference and a country name. The sorting doesn't change how the data was collected, just how it gets marketed to buyers looking for a seperate niche.

Check If You Are Affected

Precise numbers are nice, but what matters is whether your own email is in there. HEROIC's free scanner checks against more than 400 billion leaked records, letting you confirm your exposure with the same precision this file was counted with.
