Scan Yourself: Mail Acces 5K Mix Valid 100 uploaded by a Telegram User

In August 2025, HEROIC analysts came across a smaller stealer log shared on Telegram under the label "Mail Acces 5K Mix Valid 100," containing 4,770 exposed records. Despite the modest size, each entry includes an email address, a plaintext password, and the login URL the credential was captured from, the same pattern seen in malware-driven credential theft.

Why a Small Log Can Still Be Dangerous

A file of 4,770 records may look minor next to headline-making mega breaches, but for the people in it, the risk is just as real. Every credential here is a working email and password pair tied to a specific login page, which means an attacker does not need to guess anything to try logging in.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs matched to each account

Why This Matters

Even a small batch of credentials is useful for credential stuffing, where automated tools test leaked email and password combinations against other websites. Anyone in this log who reused their password elsewhere faces a real risk of account takeover, and if any of the affected logins connect to email or financial accounts, identity theft or financial fraud can follow.

How This Type of Stealer Log Gets Made

Listings labeled with terms like "mix valid" are common on Telegram marketplaces, where sellers advertise smaller, curated batches of stolen credentials pulled from malware-infected devices and verified as still working before being sold or shared. The small size actually makes the data more attractive to some buyers, since a checked, working batch is more useful than a massive unverified dump.

Check If You're Affected

Whether a leak involves thousands or billions of records, the only way to know your own exposure is to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, letting you see in seconds if your email and passwords have turned up in a log like this one.
