The ransomware supports multiple encryption modes along with intermittent encryption , providing speed and defence evasion capabilities . In addition , BlackCat uses the data destruction method to destroy essential data or render it useless , maximising the impact on the victim .
An investigation by the National Audit Office ( NAO ) has uncovered that 30 % of applications used by the Department for Environment , Food and Rural Affairs ( Defra ) are unsupported , having been developed with outdated software , increasing its security risk .
