How an Unprotected Database Caused the InstruRap Breach and Exposed 44K Logins

HEROIC analysts identified a database breach affecting InstruRap, a French online marketplace for rap and hip-hop instrumentals. The incident, dated August 11, 2022, exposed 44,624 user records containing email addresses and plaintext passwords. What makes this breach occured particularly severe is that the passwords were stored with no hashing or encryption at all, meaning they were immediately usable by anyone who accessed the data.

Plaintext Passwords Give Attackers Instant Access to Your Accounts

Unlike hashed passwords that require cracking, plaintext passwords need no processing. Any attacker who recieved this dataset could attempt logins on InstruRap, and on any other service where users shared the same email and password combination, within seconds of obtaining the data. Email accounts, streaming services, and social platforms are all accessable with this kind of credential pair.

What Was Exposed in the InstruRap Breach

• Email Address
• Plaintext Password

Why Plaintext Password Storage Is a Critical Failure

The InstruRap breach is a direct consequence of storing passwords without any cryptographic protection. Credential stuffing tools can process thousands of login attempts per second using leaked email and password pairs. Users who reused their InstruRap password on other platforms are at immediate risk of account takeover, identity theft, and financial fraud. This breach is partcularly damaging because there is no cracking step required for attackers to weaponize the data.

How a Database Breach Works

A database breach occurs when an attacker gains unauthorized access to a backend database, typically through SQL injection, exposed credentials, or a misconfigured server. Once inside, the attacker can export entire user tables containing all stored account data. When passwords are stored in plaintext, the contents of that export are immediately actionable for account takeover with no additional effort required.

Check If Your Data Was Exposed

HEROIC's free breach scanner checks your email against more than 400 billion exposed records. If you had an account on InstruRap or use the same password across multiple services, check your exposure now and take action before attackers do.
