Any files that are encrypted with WannaCry (WCry, WNCry, WanaCrypt0r) Ransomware will have the .wcry, .wcry + .WCRYT for temp (2nd variant) or .wncry + .WNCRYT for temp (3rd variant) extension appended to the end of the encrypted data filename. Since your encrypted files have no appended extension, you are not dealing with that particular ransomware.
The best way to identify the different ransomwares that do not append an extension is the ransom note (including it's name), samples of the encrypted files, information related to any email addresses used by the cyber-criminals to request payment and the malware file responsible for the infection. Without any of that information or a file marker/unique hex pattern identifier, it is difficult to determine what you are dealing with.
