How Malware Behind the “ALL VALID” Stealer Log Leaked 12 Logins

The "ALL VALID" Stealer Log Uploaded to Telegram

HEROIC analysts identified a stealer log titled "ALL VALID" that a Telegram user uploaded on 25-Jul-2026. The file is small, just 12 records, but it includes email addresses, plaintext passwords, and the URLs those logins were captured from.

Why the "ALL VALID" Label Matters

The name attached to this file is not just marketing. Sellers on Telegram and dark web forums often label a log "ALL VALID" specifically because they have already checked that every credential in it still works. That extra step of verification is what separates a pile of old, dead logins from a small but genuinely usable set of accounts an attacker can log into right now.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying which site each login belongs to

Why This Matters

Even with only 12 records, everyone in this log faces a real account takeover risk. The passwords are stored in plaintext and matched to the exact site they unlock, and the "ALL VALID" tag suggests someone has already confirmed these logins are active. If any of these passwords are reused on other sites, the exposure does not stop at one account.

How Stealer Logs Work

Stealer logs come from malware that infects a device and quietly copies whatever the browser has saved, including stored passwords, autofill details, and site URLs. Once the malware finishes collecting this data, it sends the file back to the attacker, who may test the credentials, confirm which ones still work, and then upload or sell the verified batch on Telegram, exactly as happened here.

Check If You Are Affected

Even a small leak like this one is worth checking. HEROIC's free breach scanner searches your email against a database of more than 400 billion leaked records, including stealer logs like this, and tells you immediately if you were exposed. Run a free scan and change any password it flags.
