Inside a Stealer Log: The 1.28 Million France Base Leak

HEROIC analysts identified a dataset labeled "1.28 Million france base" after it was uploaded to a Telegram channel, with underlying data dated April 2, 2023. While the name advertises 1.28 million records, HEROIC's verification process confirmed 1,046,362 actual records in the file, each one an email address paired with a plaintext password and the URL of the login page it came from, a reminder that sellers often round up or overstate record counts to make a file sound more valuable than it is.

Why This Leak Is Dangerous

Even at the verified count of 1,046,362, this remains a large-scale exposure of plaintext credentials. Because every password is stored in readable form and linked to the exact site it unlocks, attackers can run automated login attempts against a huge number of accounts with minimal effort or technical skill.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs tied to each credential

Why This Matters

At over a million records, this leak significantly raises the odds that credential stuffing attacks will succeed against at least some of the accounts involved. Anyone who reused their password across other services faces a real risk of account takeover, financial fraud, or identity theft that extends well past the original point of compromise.

How This Stealer Log Was Built

This file is a textbook example of how large stealer logs come together. Malware infects individual devices, often through pirated software or fake downloads, and quietly copies every saved browser password along with the URL it belongs to. Rather than releasing each small infection separately, sellers combine hundreds or thousands of individual logs into one large "base," label it with an eye-catching record count to attract buyers, and release it under a single name. The gap between the advertised "1.28 million" and the verified 1,046,362 records is common in this market, since inflated numbers help sellers stand out.

Check If You Are Affected

With over a million records in this single file, checking your exposure directly is the only way to know for sure. HEROIC's free breach scanner searches more than 400 billion breached records, this leak included, so you can confirm your status in seconds and secure any accounts that need it.
