Signal 43% of UK businesses hit by cyber attacks in 2024/25

Summary

According to the 2025 Cyber Security Breaches Survey, 43% of UK businesses suffered cyber attacks in the most recent twelve months of the 2024/2025 period, despite greater awareness and mitigation efforts. The report explains that breaches have wide-ranging effects including financial losses, reputational damage and theft of intellectual property. These costs are difficult to estimate accurately and often go under-reported. Ransomware in particular can prove far more costly for some firms even when no ransom is paid, because of indirect financial and operational costs. Victims who do pay a ransom are described as less likely to report the attack to Action Fraud.
