Orange suffers major data breach
Hackers accessed SIM and contact details in a cyberattack, prompting a formal complaint to judicial authorities.
Orange Belgium has confirmed a data breach affecting 850,000 customers, after a cyberattack targeted one of its internal IT systems. The attack, discovered in late July, exposed names, phone numbers, SIM card details, tariff plans and PUK codes. No financial or password data was compromised.
The telecoms provider blocked access to the affected system and notified authorities. A formal complaint has also been filed with the judiciary. All affected users are being informed via email or SMS and are urged to stay alert for phishing and identity fraud attempts.
Orange Belgium has advised users to strengthen account security with strong, unique passwords and to be cautious of suspicious links and messages. This marks the third cyber incident involving Orange in 2025, following earlier attacks, though those breaches varied in impact.
