VALENCIGA Stealer Logs For Sale: 9,490 Credentials Exposed

HEROIC analysts identified a stealer log file tied to a Telegram upload labeled LOGSYNC_VALENCIGA_BUY_TRAFFIC_LIVE_LOGS_269, dated June 22, 2025. The file contained 9,490 exposed records, including email addresses, plaintext passwords, and the URLs of the accounts those credentials belong to, all harvested directly from infected devices.

Why This Is Dangerous

The filename itself signals how this data is being marketed, as a live, ready-to-buy batch of credentials. That framing matters because it means the data is being actively sold to other criminals for immediate use, not sitting idle. Because the passwords are plaintext and paired with the exact login URL, buyers can start using them the moment they get access.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages and accounts

Why This Matters

Credentials sold as fresh, live logs are especially dangerous because they are more likely to still be valid. Anyone who reused a leaked password is at risk of credential stuffing attacks and account takeover, and the paired email addresses give attackers what they need for identity theft and financial fraud attempts.

How Stealer Log Breaches Happen

Stealer logs like this one come from infostealer malware that infects a device through a phishing link, cracked software, or a fake installer. Once active, it scans the browser for saved logins and autofill data, then packages everything into a log tied to that machine. Criminals then bundle and sell these logs, often marketing them as fresh or live to attract buyers looking for credentials that still work.

Check If You Are Affected

Do not wait to find out if your credentials are being sold in a batch like this one. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records in seconds, so you can change your passwords before anyone buys yours.
