Cyberattack takes Belgium’s main tax services offline
Belgium’s finance agency took its main online tax services offline after a cyberattack this week.
The affected services include MyMinfin, used to manage tax affairs, as well as Tax-on-web and Biztax.
The shutdown came just before an October 31 filing deadline for people reporting certain types of income, including income from self-employment or foreign companies.
The filing deadline has been extended, but accounts differ on whether the new date has been announced: one gives November 16, while another says it was still to come.
The agency says there is no current indication that data was stolen, and a spokesperson said the attack was stopped before it could access applications or data; the investigation is continuing.
Services are being restored in an isolated environment to reduce further risks, while other government applications remain fully or partly available.

What people are saying
At present, there are no indications that a data breach has occurred or that data has been compromised.
This measure helps limit the risks and makes it possible to carry out the necessary technical interventions to ensure the security of our systems.
The attack could not be sufficiently expanded within our environment to take over applications or gain access to data.
