Eurofiber France Says Hacker Tried to Sell Customer Data in Breach Warning

[johny899]

I saw some news the other day that made me think, "Oh no, not again." Eurofiber France said that a hacker broke into one of their systems and offered to sell the stolen customer data. If you use any internet or cloud services, this kind of news is always difficult to hear, right?

What Happened​

Eurofiber France became aware of unauthorized access to its ticket system and ATE customer portal.

The hacker (ByteToBreach) boasted that he acquired:

• Screenshots
• VPN settings
• Source-code files
• Backups
• Login credentials

They even mentioned that the data was related to approximately 10,000 corporations and government institutions.

What Did Eurofiber Say?​

Eurofiber held that the good news is that bank details were not compromised. They also commented that the incident only affects France and not the Dutch, German, or Belgian clients.

Eurofiber acted quickly to resolve the matter, increased security, and notified French cyber authorities.

Why Should You Care​

This is not just one company getting hacked, it matters because:

• A breach like this can injure many businesses that use Eurofiber’s service.
• The hacker did not steal something trivial like a name, he claims he stole configured files, backups, and passwords, which are much more concerning.
• The hacker is now attempting to sell or utilize the data, creating long-term trouble further down the line.

I once worked with a small company that had a single password leak. I shrugged it off until I saw how simple a password can reach. I learned to take these seriously.

What You Should Do (If You Are A Customer or Vendor)​

Here are a few simple actions to consider:

• Inquire with Eurofiber or your provider if there is any chance your data was included,
• Change your keys and passwords--particularly if you ever uploaded files to their ticketing system.
• Also look at your own security, because if your provider has been attacked, then your business may also be compromised.
• Audit your backup and emergency plans so that you are prepared to react swiftly next time,
• And monitor the third-party tools because weak tools always create the greatest headaches.

Final Thoughts​

This Eurofiber France breach demonstrates how an impacted minor system like a ticket portal can still impact thousands of businesses across various industries.
