Ransomware Attacks Surge in Q1 2025 as Immutable Backup Emerges as Critical Defense

Ransomware attacks have seen a dramatic rise in the first quarter of 2025, with new research from Object First revealing an 84% increase compared to the same period in 2024.

A large majority—81% of IT decision-makers—now recognize that immutable backup storage is the most effective defense against ransomware. Immutable storage ensures that once data is written, it cannot be changed or deleted, offering a critical safety net when other security measures fail. This form of storage plays a key role in enabling organizations to recover their data without yielding to ransom demands.
