Search Your Email: The MixFiend Breach Exposed 193,904 Accounts

HEROIC analysts identified a data breach tied to MixFiend, a U.S.-based hip-hop and mixtape community platform, when a dataset appeared on a prominent hacking forum on March 18, 2019. The breach affected 193,904 users and exposed email addresses alongside plaintext passwords -- a dangerous combination that gives attackers everything they need to access accounts directly. Because the data was posted publicly on a well-known forum, it was quickly absorbed into combolists used in automated attacks across the internet.

Why This Is Dangerous

Plaintext passwords are the worst-case outcome in any breach. Unlike hashed passwords, they require zero cracking -- an attacker can recieve your exact password and immediately try it everywhere. With your MixFiend email and password in hand, a bad actor can attempt to log into your Gmail, Netflix, bank, or any other service where you used the same credentials. This type of attack, called credential stuffing, is largely automated and runs at massive scale within hours of a dataset being released.

What Was Exposed

• Email Address
• Plaintext Password

Why This Matters

Password reuse is one of the most common security habits online, which is exactly why breaches like this one have consequences far beyond the original platform. Even if you never cared much about your MixFiend account, the credentials you used there may still be protecting other accounts you do care about. Credential stuffing attacks, account takeovers, identity theft, and financial fraud all become significantly more likely when plaintext passwords from a breach enter circulation. The data from this breach has had years to propogate through dark web markets and private Telegram channels.

How a Database Breach Works

A database breach occured when an attacker gains unauthorized access to the backend systems of a website or application. In MixFiend's case, the attacker exfiltrated the platform's primary user database -- the table that stores login credentials for every registered account. Once that database is copied and posted to a hacking forum, anyone can download it. Platforms that store passwords in plaintext (instead of using a one-way hashing algorithm) make this especially dangerous, because there is no additional layer between the attacker and your actual password.

Check If You Are Affected

HEROIC's free scanner searches across more than 400 billion breached records to tell you instantly whether your email address appears in this breach or any other known data leak. If you used MixFiend at any point before 2019, your credentials may be circulating right now. Run a free seperate check for every email address you use -- it only takes seconds and could prevent a serious account compromise.
