Based on the firm’s 2025 InsurSec Report, ransomware activity rose 20 percent from the previous year, returning to the high level of threat that had been experienced in 2021, when ransomware activity soared to 20 per cent. 

There is an overwhelmingly large number of remote access tools and virtual private networks (VPNS) that have been exploited as entry points for these attacks, according to the report. In particular, mid-market organisations, particularly those with annual revenues between $25 million and $100 million, have been severely hit by this surge, with targeted incidents on the rise by 46 per cent.

It was also found that attacks originating from third parties, such as vendors and service providers, have increased by 43 per cent, compounding the risk.
