Global Users Targeted: Mix Stealer Log Exposes 27,360 Passwords

HEROIC analysts identified a stealer log collection simply titled "Mix" that was uploaded to a Telegram channel in May 2026. The dataset contains 27,360 compromised records spanning a wide variety of websites and online services worldwide. Each record exposes an email address, a plaintext password, and the URL of the service where the login was used. The generic "Mix" label indicates a broad, multi-service collection drawn from diverse infostealer infections.

Why Plaintext Passwords in a Global Mix Are Universally Dangerous

All 27,360 passwords in this collection are stored in plaintext — fully visible, unencrypted, and ready for immediate exploitation. An attacker needs no specialized tools, no computing power, and no time to crack these credentials. They work the moment they are read. The global nature of this collection means victims span multiple countries and use services across every industry sector.

Plaintext credentials from a mixed dump are especially versatile for attackers. Unlike service-specific leaks where credentials only work on one platform, a mixed collection provides working logins across banking, email, social media, cloud storage, and corporate platforms simultaneously. Every record is a potential entry point into multiple areas of a victim's digital life.

What Was Exposed in the Mix Stealer Log

• Email Addresses — Thousands of email addresses from major global providers and corporate domains, functioning as both login credentials and direct communication channels for phishing operations.
• Plaintext Passwords — Unprotected, fully readable passwords harvested from browser autofill systems and saved credentials on compromised devices across the globe.
• URLs — The specific login pages and services where each credential was captured, providing attackers with a detailed catalog of targets for each victim.

Why 27,360 Cross-Platform Credentials Fuel Widespread Attacks

A mixed-service dump of 27,360 records gives credential-stuffing botnets enormous range. Each email-password pair can be tested against hundreds of different platforms in a single automated run. The diversity of services represented in the collection means attackers can target everything from online banking to streaming subscriptions to enterprise cloud platforms without needing separate datasets.

Password reuse dramatically amplifies this already broad threat. With studies showing that over 60% of users rely on the same password across multiple accounts, each of these 27,360 credentials may unlock access to several additional services. The aggregate impact of this single dump could extend to well over 50,000 compromised account logins across the internet.

How Stealer Logs Produce Cross-Service Credential Collections

Infostealer malware is indiscriminate by design. Variants like RedLine, Lumma, and Vidar extract every credential saved in every browser on an infected device. A single victim might have credentials for their email, bank, social media, streaming services, and work applications all captured in one pass. When thousands of individual device logs are merged, the result is a rich, cross-service collection like this Mix dump.

These mixed collections are the workhorses of the credential-trading economy on Telegram. They appeal to the widest range of buyers because they contain something for everyone — email credentials for account takeover specialists, banking logins for financial fraud operators, and corporate credentials for ransomware groups seeking initial access. A single download of the Mix collection hands every one of these threat actors a ready-made attack toolkit.

Check If Your Credentials Appear in This Leak

Because mixed stealer logs capture credentials from every type of online service, virtually anyone who saves passwords in their browser is a potential victim. This collection surfaced in May 2026, making it extremely recent and increasing the likelihood that affected credentials are still active.

Use HEROIC's free breach scanner to check whether your email address or passwords appear in the Mix stealer log dump or across our database of 400B+ compromised records. Identifying and changing compromised credentials quickly is the single most effective step you can take to prevent unauthorized access to your accounts.
