The Dutch Tax Administration (Belastingdienst) sent me a trophy and formal letter of appreciation on behalf of the Dutch government.

Dutch Tax Administration Trophy

The front engraving on the trophy playfully reads, “I hacked the Dutch Tax Administration and never got a refund”.

Together with the trophy was a formal letter of appreciation.

On behalf of the Dutch Tax and Customs Administration, we would like to thank Jacob for participating in our Coordinated Vulnerability Disclosure program. For that, we present this letter of appreciation to Jacob.

At the Dutch Tax and Customs Administration, we consider the security of our systems a top priority. But no matter how much effort we put into system security, there can still be vulnerabilities present. For that, we warmly welcome people like Jacob as a particpiant in the Coordinated Vulnerability Disclosure program.

We appreciate not only that you have reported a security issue to us, but also that you have professionally done this.

I would like to extend my thanks to the Belastingdienst Security Operations Center for sending me such a kind gift.
