How long does data recovery take after a ransomware attack?
The recovery time after a ransomware attack varies greatly depending on the complexity of the case:
- Ransomware already decrypted (public key available): 24 to 72 hours to apply decryption to all files
- Recovery via intact backups: from a few hours to a few days depending on the volume of data and the state of the infrastructure
- Forensic analysis and search for cryptographic flaws: from 1 to several weeks—some analyses require significant computing resources
- Cases with no known decryption solution: retention of encrypted files pending a key being published later (Hive, Ragnar Locker, etc. cases)
