Recent events have reminded us of the fact that cyber risks are an increasingly daunting challenge for Belgian entrepreneurs. In May 2017, one of the largest cyber attacks so far was launched, using the WannaCry/WannaCrypt ransomware. The impact of this attack was felt all over the world. Several Belgian companies also received a ransom demand and were given the choice to pay or lose all their data. Enterprises and institutions in more than 150 countries, including Belgium, fell victim to the attack.
