Industry-wise, Blacknevas shows a concentration in the Consumer Services, Manufacturing, Technology sectors. These industries are frequently targeted because they manage sensitive data, critical operations, or have lower tolerance for operational downtime โ conditions that increase ransom payment likelihood.
