Data breach lessons: how to protect yourself online
A South Korean e-commerce giant has just been hit with a record £299m fine for a massive data breach affecting 37.5 million customers. While this happened abroad, it’s a stark reminder of why you need to protect your personal information — especially when shopping online.
The company, Coupang (often called South Korea’s Amazon), exposed names, addresses, delivery details and order histories after poor security left customer data vulnerable for months. The breach began as early as June last year but wasn’t fully discovered until November. It’s a cautionary tale for all of us who shop online regularly.
Why this matters to you
If you’ve ever bought something online, your data is stored somewhere. Banks, retailers and delivery companies all hold sensitive information about you. When security fails — like in this case — that information can fall into the wrong hands. Criminals can use leaked addresses for burglary, contact details for phishing scams, or order histories to impersonate you.
What you can do to stay safer
Use strong, unique passwords for every online account you care about. A password manager like Bitwarden or 1Password can help you create and store these securely. Enable two-factor authentication (an extra login step) wherever it’s available — especially for email and banking apps.
Be cautious about what information you share online. Do retailers really need your date of birth? Think twice before providing extra personal details.
Check your bank and credit card statements regularly for suspicious transactions. If you spot anything odd, contact your bank immediately. You can also get a free credit report from Clearscore, Experian or Equifax to see if anyone’s tried to open accounts in your name.
Where to get help
If you think your data has been compromised, report it to Action Fraud (actionfraud.police.uk) or the Citizens Advice consumer service. The Information Commissioner’s Office (ICO) also handles UK data protection complaints.
Stay vigilant — it’s the best defence against becoming a victim.
