What Happened?
The customers say Odido didn’t protect their personal information properly. They claim the company kept their personal information for too long and failed to keep it safe.
They also say Odido did not clearly explain what happened after the breach. On top of that, they add that the company did not fully follow Europe’s data protection rules.
Now, the consumer group is asking for compensation for people affected by the breach. They also want Odido to take responsibility and explain exactly how this happened. So far, the company has not responded.
How Did the Attack Happen?
Hackers broke into Odido’s systems and stole customer data.
On February 24, 2026, a hacker group called ShinyHunters said they carried out the attack. This group is known for stealing large amounts of personal information.
After the attack, they demanded money. Odido refused to pay. Soon after, the hackers posted the stolen data online on the dark web.
There are also reports that Odido may have ignored earlier warnings from Salesforce (a company that helps businesses store and manage customer data) about possible security risks.
If that’s true, this breach might have been preventable.
Who Is Affected?
This breach affects both current and former Odido customers in the Netherlands.
It also includes people who used related brands, such as:
- Odido
- T-Mobile
- Tele2
- Ben
In total, more than 6.2 million people may be affected.
What Data Was Leaked?
The hackers got access to very personal data, including:
- Full names
- Home addresses
- Phone numbers
- Dates of birth
- Bank account numbers
- Customer ID numbers
- Government ID documents, like passports or driver’s licenses
What This Breach Means for You
This isn’t just about one company. It’s about how your data gets used after a breach.
When personal details leak, scammers don’t guess — they go after specific people.
They can use your information to act as you, like trying to open accounts in your name. Identity fraud remains one of the most common types of fraud, with more than 242,000 cases reported in 2025 alone.
Scammers can also send messages that include your real name or other details, which makes them look legitimate.
For example:
- A text that looks like it’s from your bank
- An email asking you to “confirm” information
- A security alert that includes your personal details
That’s what makes these scams harder to spot — they feel real.
This case also shows: The more data a company keeps, the bigger the damage if it leaks. If companies still keep your old data, it can affect you even years later.
Data breaches don’t end when the news fades. They can lead to ongoing scams and long-term risk.
If you’re not sure whether your data has already been leaked, it’s worth checking.
With Futureproof, you can quickly see if your data has been leaked and get clear, simple steps to protect your accounts. It’s a simple way to stay one step ahead of potential scams.
5 Simple Steps to Protect Yourself After the Breach
Even if you were not affected by this breach, it is a good time to reconsider your habits:
- Be careful with unexpected messages or calls
If you get a text about a “problem with your account” or a call asking for personal details, slow down. Real companies don’t pressure you to act right away.
- Do not click links in messages you weren’t expecting
If you receive a “delivery failed” or “verify your account” message out of the blue, ignore the link. That’s a common way scammers try to trick you.
- Use official contact details to check anything
If a message says there’s a problem, don’t answer right away. Go to the company’s official website and use the phone number or support page listed there. This helps you confirm you’re dealing with the real company and avoid fake websites.
- Check your bank and credit card activity
Open your bank’s mobile app or log in to your account on the official website. Go to your recent transactions or activity page. Look through the last few days and weeks for small charges you don’t recognize. Scammers often test with a small amount before trying something bigger.
- Add extra protection to your key accounts
Use strong, unique passwords and turn on two-step verification. Start with your email as it is connected to your bank, shopping accounts, and more. If someone gets into your email, they can reset passwords for your other accounts and take control of them.
Use a different password for each account so one breach doesn’t affect everything else.
Futureproof Email Protection walks you through setting a strong email password and turning on two-step verification with clear, step-by-step help. It makes it much harder for anyone to break into your account and steal your data.
The Real Problem Isn’t the Hack — It’s Your Data that Doesn’t Go Away
The Odido breach is a reminder that your personal data doesn’t disappear once you stop using a service. It can sit in a company’s systems for years — and when something goes wrong, you’re the one left dealing with the consequences.
You can’t control what companies do with your data. But you can control how prepared you are.
Check if your data has leaked with tools like Futureproof, secure your key accounts, and stay alert to anything that feels off.
Because in many cases, the real risk isn’t just the breach itself — it’s everything that follows.
