Your MojSklepOgrodniczy Data May Be at Risk: Here’s What You Need to Know

A dataset tied to MojSklepOgrodniczy, a Polish online garden center that is no longer in operation, was leaked on a hacking forum in August 2018 and exposed 22,813 user records. The compromised data included email adresses and password hashes, with some passwords stored using the widely cracked MD5 algorithm. Even though the breach occured years ago, old credentials like these continue to show up in credential stuffing attacks because so many people still use the same passwords across multiple accounts.

Why This Is Dangerous

MD5-hashed passwords are not safe. The algorithm has been considered broken for years, and there are massive precomputed lookup tables called rainbow tables that can reverse MD5 hashes for common passwords in seconds. If your password from this site was anything less than long and truly random, there is a good chance it has already been cracked by now.

The other password hashes in this dataset use formats that have not been fully identified, but unknown hashing schemes can also be weak, especially if they were put together by a small e-commerce site without dedicated security expertise. Once cracked, those plaintext passwords go straight into combolists used in automated attacks across the internet.

Poland-based breaches like this one often fly under the radar for international users, but the data still circulates globally on dark web markets and hacker forums. Email and password combinations from this leak have had years to be used, shared, and folded into larger combolist files that remain in active circulation today.

What Was Exposed

• Email addresses used to register on the platform
• MD5 password hashes (easily cracked with modern tools)
• Password hashes in other, unidentified formats
• Account registration data from the garden center site
• Usernames or display names linked to user profiles
• Potentially shipping or contact details from order history
• Account creation timestamps tied to user records

Why This Matters

Data from breaches at defunct companies like MojSklepOgrodniczy does not disappear when the company closes. The records stay in circulation on dark web forums and get folded into combolists that are used for credential stuffing against entirely unrelated websites. The age of the breach is irrelevant if you were still using that same email and password combination anywhere else at the time or after.

For Polish internet users especially, this breach represents a real ongoing risk. Email adresses tend to stay consistent across years of online activity, and if the password from this account matches one still in use today, that account is vulnerable right now. The combination of a working email plus a crackable hash is more than enough to mount a serious account takeover attempt.

How Database Combolist Works

A database breach happens when an attacker gains unauthorized access to a website's backend and pulls the user database. This can happen through SQL injection, an unpatched software vulnerability, or a compromised admin account. Once the attacker is inside, they download the user table and walk away with every registered email and stored password hash.

That database dump then gets posted to hacker forums or sold to other criminals. Over time, these dumps get combined with records from other breaches into massive combolist files that aggregate millions of credentials from hundreds of sources. Automated tools then test each email and password pair against popular websites at scale, looking for matches.

When the passwords use weak hashing like MD5 without a salt, cracking them is straightforward. Attackers run the hashes through rainbow tables or GPU-accelerated cracking tools and recover the original passwords within hours or days. The cracked credentials then get added to fresh combolists and recirculate through the criminal ecosystem, sometimes for many years after the original breach.

Check If You Were Affected

If you ever had an account with MojSklepOgrodniczy or used the same email and password on other sites, your credentials may beleive it or not still be in active circulation. Do not wait for an account takeover to confirm it. Use HEROIC's free breach checker at heroic.com to search your email address across all known breach databases and see exactly what has been exposed.
