Ransomware attacks 2025-2026

Ransomware activity is expected to remain a significant cybersecurity threat in Q2 2026, with increasing sophistication and targeted attacks on critical sectors like healthcare and finance. Double extortion tactics, where attackers encrypt data and threaten to release it, will likely continue, alongside the proliferation of Ransomware-as-a-Service (RaaS) models. The use of cryptocurrencies for ransom payments is expected to persist despite regulatory scrutiny. Supply chain attacks may rise, amplifying the impact on multiple organizations. In response, organizations are anticipated to invest more in preventive measures, incident response strategies, and employee training, while governments and international bodies enhance efforts to combat ransomware through legislation and cooperation.
