100Private M_P Leak: Exactly 275,080 Records Confirmed

In August 2023, HEROIC analysts logged a stealer log file labeled "1200000 100Private M_P," uploaded to a Telegram channel by an anonymous user. After analysis, the file was found to contain 275,080 records of email addresses, plaintext passwords, and the website URLs each login belongs to.

The Precise Scope of This Exposure

The file's name suggests a headline number in the millions, but the confirmed, usable total comes to exactly 275,080 individual records. That is still a substantial amount of exposed data, and every single entry pairs a real email address with a plaintext password and the exact site it unlocks.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated website URLs

Why This Matters

Plaintext passwords tied directly to their matching login pages remove almost every obstacle for an attacker. This kind of data is routinely used for credential stuffing, account takeover, and downstream identity theft or financial fraud, especially when people reuse the same password across multiple sites.

How Stealer Logs Work

Stealer malware infects a device, often disguised as pirated software or a fake update, then quietly copies saved browser passwords, autofill entries, and session cookies. The results are compiled into a log file and distributed, frequently through private Telegram channels like the one connected to this exposure. Because the data comes straight from the browser, it tends to be accurate and current at the time of infection.
