Hacker News’s article “Ransomware Is Growing Three Times Faster Than the Spending Meant to Stop It”:

Ransomware leak-site claims surged 30.7% year-over-year in 2025 to reach 7,760 incidents, significantly outpacing the 10.1% growth in worldwide security spending ($213 billion), indicating a widening gap between observable threat volume and security investment.

The article doesn’t say what is causing this surge, and if AI has anything to do with it. I would bet that AI might be helping hacker groups.
