No critical data was compromised in the end-of-July incident, the firm said, explaining that its clients’ passwords, email addresses, bank and financial details were not affected.
“However, the hacker gained access to one of our IT systems containing the following data: surname, first name, telephone number, SIM card number, PUK code, tariff plan,” Orange Belgium said in a statement.
“As soon as the incident was detected, our teams blocked access to the affected system and tightened our security measures.”
The firm, the Belgian business of French telecommunications company Orange, said it alerted the competent authorities and affected customers would be notified by email and text message.
“We advise them to remain vigilant for any suspicious communications,” Orange Belgium said.
