Dark Web Intel: 5,604 Credentials From the VALENCIGA Stealer Log

HEROIC analysts identified a stealer log labeled "LOGSYNC_VALENCIGA_BUY_TRAFFIC_LIVE_LOGS_248" uploaded to a Telegram channel on June 2, 2025. The file contained 5,604 records, each pairing an email address with a plaintext password and a related URL, the signature of infostealer malware pulling saved credentials directly off infected devices.

Why the VALENCIGA Stealer Log Is Dangerous

Over 5,600 complete login records were exposed with the passwords stored in plaintext, so an attacker does not need to crack or guess anything to use them. Because each record also lists the URL the credentials belonged to, an attacker can move straight from the log to a working login, or try the same combination against other popular services in case the password was reused elsewhere.

What Was Exposed in the VALENCIGA Leak

• Email addresses
• Plaintext passwords
• URLs of the associated login pages or services

In total, 5,604 records were included in the file.

Why This Matters

A log of this size is exactly the kind of data used in credential stuffing campaigns, where stolen email and password pairs are tested automatically across many other sites. Because each record already ties a password to the exact service it opened, it also speeds up account takeover for anyone who reused that password elsewhere, extending the risk to financial fraud and identity theft.

How a Stealer Log Like VALENCIGA Gets Built

Infostealer malware infects a device and quietly copies saved browser passwords and the URLs tied to them before sending everything back to whoever controls the malware. The file's own label, which references buying and selling traffic and live logs, suggests it was packaged specifically for sale or trade among other criminals rather than for a single private use. Logs like this are routinely bought, sold, and redistributed across Telegram channels and dark web marketplaces.

Dark Web Intel: Check If You Are Affected

With over 5,600 accounts in this single log now circulating on the dark web, the odds that your information is included are real. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, so you can see what has been exposed and change any reused passwords before someone else does.
