One Reused Password Could Betray 70,149 Leaked Accounts

HEROIC found a large mixed stealer log file labeled "Mix 30.08" that was distributed on Telegram in February 2023. The collection spans 70,149 records drawn from multiple online services, with each entry containing an email address, a plaintext password, and the URL of the site where the credential was intercepted. The breadth of services represented makes this dump a versatile weapon in the hands of cybercriminals.

Why Plaintext Passwords Are an Open Door

All 70,149 passwords appear in this file exactly as they were typed by the victims. No hashing, no salting, no encryption of any kind protects these credentials. An attacker downloading this file gains immediate, frictionless access to try every single login. When passwords are stored in plaintext, the only remaining barrier is whether the victim has since changed their password or enabled additional security measures.

What Was Exposed

• Email Addresses — from a wide variety of providers and services
• Plaintext Passwords — stored without any form of cryptographic protection
• URLs — identifying the diverse range of websites where credentials were stolen

The Domino Effect of Credential Reuse

Mixed dumps like this one are prized by attackers because they contain credentials spanning many different services. Automated credential stuffing tools can test each email-password pair against banking, email, cloud storage, social media, and enterprise platforms in rapid succession. A single match cascades quickly: once an attacker enters your email account, they can reset passwords on every connected service, locking you out of your own digital life.

From Infected Device to Telegram Channel

Stealer log files like Mix 30.08 are generated by infostealer malware that quietly runs on compromised devices. The malware captures credentials from browser password stores, form submissions, and autofill data. It also harvests session cookies and authentication tokens that can grant access even when two-factor authentication is enabled. Once collected, these credential bundles are compiled, categorized, and shared on Telegram, reaching thousands of potential attackers.

Check If Your Credentials Were Exposed

With over 70,000 credentials from varied services in this dump, the odds of being affected increase if you use multiple online platforms. HEROIC's breach scanner indexes more than 400 billion compromised records, offering comprehensive coverage across known data breaches. Search your email or password now to find out if you are exposed, and immediately update any credentials that appear in the results.
