The Logs_5 March Leak Exposed 105,040 United States User Passwords

HEROIC analysts identified a stealer log dataset titled Logs_5 March uploaded to a public Telegram channel on March 5, 2025. The file contains 105,040 records tied to United States users, each pairing an email address with a plaintext password and the URL of the account it belongs to.

Why This Is Dangerous

Because the passwords in this dataset are plaintext, there is nothing standing between an attacker and the account once they open the file. Each record also comes attached to the specific URL it was harvested from, meaning an attacker knows exactly which site or service each stolen login opens, with no guesswork required.

What Was Exposed in the Logs_5 March Leak

• Email addresses
• Plaintext passwords
• URLs of the associated accounts or services

Why This Matters for the 105,040 People Affected

Data like this is used almost immediately for credential stuffing, where automated tools try each stolen email and password pair across dozens of other sites. Anyone who reused a password elsewhere risks account takeover, identity theft, or direct financial fraud on accounts that were never part of the original infection.

How This Stealer Log Was Collected

Stealer logs are produced by infostealer malware that infects a device, then quietly copies saved browser passwords, autofill data, and login URLs before sending everything back to whoever controls the malware. That stolen information is bundled into a file and shared or sold through channels like Telegram, which is exactly how this dataset became public.
