AIG queried 70 cybersecurity, technology, and insurance professionals, in the study, and found that the industries most likely to face a systemic attack this year are:

More than half of the survey respondents believe a simultaneous attack will occur involving five- to 10 companies, while one-third of those surveyed believe there is more than an even chance that as many as 50 companies will be attacked simultaneously. As for the remaining 20% of survey respondents, they think the number of companies that could be attacked at once could reach into as many as 100 businesses.
