Different threats to different types of organizations
Attackers appear to choose targets based on multiple dimensions, such as the size and the type of the organization, its country of operation, and the organization’s sector of activity. Let’s look at an example of corporate users across businesses, nonprofits, government-related industries, and education services. If we consider business inboxes as a baseline, we find attackers are far more likely to target nonprofits with malware, while attackers are more likely to target businesses with phishing and spam.

These nuances go all the way down to the granularity of country and industry type. This shows how security and abuse professionals must tailor defenses based on their personalized threat model, where no single corporate user faces the same attacks.
