Although there is evidence that some victims of the WannaCry ransomware attack on 12 May have paid the attackers, there is no evidence that they are getting their data back

In response to the apparent failure of those behind the WannaCry ransomware to deliver decryption keys to victims who elect to pay the ransom, McAfee researchers have tested a potential recovery method.
