But the altruistic sharing of threat intelligence has a significant impact on both the specific and systemic aspects of cyber risk.Communities respond collectively to cyber threats — the larger the scale of the incident, the larger the community response. In natural catastrophe modeling, we expect buildings to be better constructed over time as technology gradually improves, but no one expects a building to develop stronger resilience while the hurricane rages in real time.
However, in the case of a widespread cyber incident, the corporate sector, the tech titans, individuals, industry groups, and governments all join together to face the common foe. The community-driven “No More Ransom”1 project is a good example of this. It is estimated to have saved victims $1.5 billion by providing free decryption tools to those who have suffered ransomware attacks.
