Belgium's federal finance and tax service, FOD Financiën, confirmed a cyberattack on Wednesday, October 28, and took several online services offline, including its main tax portal MyMinfin, Tax-on-web and Biztax, The Register reports.

The agency said there were no signs that data had been accessed or stolen, and a spokesperson told local media the attack was stopped within hours before it could take over applications. Potentially infected parts were isolated, and services are being restored in an isolated environment, which takes time.

Because MyMinfin is where some filings are made, the October 31 deadline for certain income types, such as sole traders and earnings from foreign companies, moves to November 16.
