The Municipality of The Hague, in cooperation with cyber security company Cybersprint, will organise the ‘Hâck The Hague’ hacking competition for the 3rd year in a row on 30 September 2019. This year the municipality will be hacked by 100 of the best national and international ethical hackers.

The Atrium of The Hague City Hall will be transformed into ‘The Hague Hackers Dome’ during Hâck The Hague 2019. One hundred professional hackers and students will be invited to detect digital vulnerabilities in the digital infrastructure of the municipality and its suppliers. Prior to the One Conference on international cyber security, the Municipality of The Hague will have its own digital security tested.

Hacking contest

Hackers will try to break into the municipality’s digital systems and the systems of a number of selected suppliers on 30 September. There are rules all parties must adhere to. For example, the hackers must first agree to report any vulnerabilities and evidence in a special portal and not to make them public, as stated in the rules of Responsible Disclosure. The Municipality of The Hague pledges that the handling of personal data and availability of its services continually meet the highest possible security requirements, even during this hacking competition.

The hackers will compete in the most advanced hack, the hack with the greatest impact, and the most creative hack. The winners will receive cash prizes.

Results of Hâck The Hague 2018 

Last year 45 professional hackers tested the Municipality of The Hague’s digital systems. This resulted in 64 found vulnerabilities, 1 of which was so severe that the system was immediately switched off. The Municipality of The Hague right away went to work to solve the found vulnerabilities.
