About MOUNT10 Blog Ransomware Attack

What happens during a ransomware attack?

A ransomware attack is not an IT problem – it is a business risk.

When systems come to a standstill, it affects not just the IT department, but the entire organisation: production grinds to a halt, customers cannot be served, revenue plummets and regulatory compliance comes under pressure.

In many cases, it is only when a crisis strikes that it becomes clear just how dependent the company is on functioning data and systems – and how quickly that availability can be lost.

The crucial question is therefore not whether an attack will happen, but how well your company is prepared to resume operations quickly.
