Odido, the Netherlands' biggest mobile phone operator, disclosed a massive data breach affecting up to 6.2 million customers last week. Hackers accessed the company's customer contact system, stealing names, addresses, email addresses, bank account numbers, birth dates, and passport or driver's license numbers.

While Odido emphasized that passwords, call records, and billing data weren't compromised, cybersecurity experts warn the stolen information could fuel convincing phishing attacks and identity fraud. The company quickly ended unauthorized access and brought in external security experts to strengthen defenses.

Odido is warning customers to watch for suspicious calls, texts, and fake invoices appearing to come from the company. Affected users will be contacted directly by Odido.
