The USA 0918 Stealer Log: 457,453 Stolen Accounts Exposed

The USA 0918 Stealer Log: 457,453 Stolen Accounts Exposed

HEROIC analysts identified a large stealer log labeled USA 0918, uploaded to a Telegram channel on 11 February 2023. The file contained 457,453 records, each pairing an email address with a plaintext password and the URL of the site the credential was used on. This is one of the larger single files HEROIC has tracked, representing nearly half a million individual login credentials pulled from infected devices across the United States.

Why This Is Dangerous

Because this data comes from malware that captured credentials directly from victims' browsers, the 457,453 email and password pairs in this file reflect logins that were active and in use at the time of infection. An attacker does not need to guess or crack anything. The email, the plaintext password, and the exact site it unlocks are already paired together, and with nearly half a million entries, an attacker has an enormous list to automate against.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites where the credentials were used

Why This Matters

A file of this size gives attackers the raw material to run large-scale credential stuffing campaigns, automatically testing each email and password pair against banking sites, email providers, and social media platforms. If any of the 457,453 people in this leak reused a password across accounts, that single leaked credential can open the door to several more. From there, account takeover, identity theft, and financial fraud become widespread risks rather than isolated incidents.

How Stealer Logs Work

A stealer log is produced by information-stealing malware that infects a device, typically through a pirated download, a fake software update, or a malicious attachment. Once running, it quietly harvests saved passwords, autofill entries, and open browser sessions, then packages everything into a text file. Large logs like this one, covering hundreds of thousands of accounts, are usually compiled from many thousands of infected devices, pooled together over time and shared or sold on Telegram channels and dark web forums, where criminals sort through them looking for accounts worth targeting.
