Statement from Orange Belgium S.A. on August 20 2025:
At the end of July, Orange Belgium detected a cyberattack on one of its IT systems, resulting in unauthorised access to certain data from 850,000 customer accounts.
No critical data was compromised: no passwords, email addresses, bank or financial details were hacked.
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.
As soon as the incident was detected, our teams blocked access to the affected system and tightened our security measures. Orange Belgium also alerted the competent authorities and filed an official complaint with the judicial authorities.
The affected customers have been or will be notified by email and/or text message. We advise them to remain vigilant for any suspicious communications.
For more information, customers can consult our dedicated web page.
Due the ongoing investigation, no further details will be disclosed to ensure the integrity of the investigation and protect the privacy of those involved.
