Belgian tax agency takes services offline after cyberattack
First merged summary.
Belgium’s finance agency took MyMinfin and related tax services offline after a cyberattack and is extending some October 31 filings.
Belgium’s tax agency, FPS Finance (FOD Financiën), confirmed a cyberattack and took MyMinfin offline while securing systems ahead of an October 31 filing deadline. Francis Adyns said the attack was stopped within hours without reaching applications or data, and isolating suspect systems also took Tax-on-web and Biztax offline; the agency reports no sign of a data breach. The Record said exposure checks were continuing and a new deadline was not yet set, while The Register reports the October 31 filings for sole traders and foreign companies move to November 16. Other applications remained fully or partly available. The attacker and method are unknown; The Record says any link to an earlier PHP-flaw shutdown is unclear, and Belgium’s cybersecurity center reported no successful exploitation of those flaws on Belgian sites.
