The number of ransomware attacks rose sharply in the first half of 2025, with 4,198 cases recorded on the dark web, a 49% increase from previous year. US companies, especially small and medium-sized businesses, faced the greatest impact, constituting 49% of total incidents. Factors contributing to this rise include Ransomware as a Service (RaaS), changes in work models, and economic factors pushing individuals towards cybercrime. The manufacturing, construction, and IT sectors experience the highest incidents, reflecting challenges in security enforcement and reliance on outdated systems.
We're only halfway into the year, but the number of ransomware attacks has already doubled, signifying that these attacks remain effective and profitable enough for cyber criminals to ramp up their efforts.
Some factors that could contribute to the growth in ransomware attacks include the rise in Ransomware as a Service (RaaS), expanded attack surfaces from remote or hybrid work models and economic uncertainty that could encourage more people to seek illegal income and turn to cybercrime.
Not only is the US home to many profitable businesses, but the companies also have a higher profile. As a result, they're more likely to give into ransomware demands to reduce the impact of the reputational damage resulting from an attack.
Strict regulations are also a significant factor to consider - laws on data protection and operational uptime can urge companies to resolve ransomware incidents quickly and not risk the fines or loss of their clients and partners' trust.
