Inside Le Gouessant Aquaculture: How Plain Text Exposed 78K Users

HEROIC analysts discovered the Le Gouessant Aquaculture breach while reviewing credential datasets that had recieved fresh circulation in underground trading channels. The breach took place in November 2017 and exposed 78,725 records from a French ecommerce platform specializing in aquaculture products. The compromised data included email addresses and passwords stored in plain text, meaning any attacker with access to the database could read every password instantly without needing any technical tools to decode them.

Why Plain Text Passwords in an Ecommerce Breach Are Especially Dangerous

When an ecommerce platform stores passwords in plain text, the damage from a breach goes well beyond a single website. Customers who used the same email and password combination to shop on Le Gouessant Aquaculture and on other online stores are now at direct risk of having those other accounts accessed without their knowledge. Attackers can use the stolen credentials to log into retail accounts, access saved payment methods, redirect deliveries, and make fraudulent purchases. This type of account takeover is occured frequently in ecommerce because password reuse is very common among online shoppers.

How a French Ecommerce Breach Can Affect Shoppers Years Later

Old breach data does not become harmless with age. Credentials from the 2017 Le Gouessant Aquaculture breach are still being traded and tested against other websites today. Shoppers who have not changed the password they used on this platform remain vulnerable to credential stuffing attacks, where automated tools test their email and password against hundreds of services at once. A successful login on even one of those services can lead to identity theft, unauthorized purchases, and financial fraud as attackers move through connected accounts.

How a Database Breach Works

A database breach happens when an attacker finds a way past the security controls of a website and gains access to the backend system where user data is stored. This can involve exploiting software vulnerabilities, guessing or stealing administrator passwords, or taking advantage of misconfigured servers. After gaining access, the attacker copies the entire user database and removes it from the company's systems. The stolen data is then sold, traded, or used directly in attacks. In cases where passwords are stored in plain text, the stolen data requires no further processing before it can be used to attempt unauthorized logins on other websites.
