Orange Belgium announced that it detected a cyberattack on one of its IT systems at the end of July, 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 their 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, Orange Belgium’s teams blocked access to the affected system and tightened its 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. The company advise them to remain vigilant for any suspicious communications.
Due the ongoing investigation, no further details will be disclosed to ensure the integrity of the investigation and protect the privacy of those involved.
