Hi Kevin, Great tool! We got the I_LOVE_YOU_BRUCE ransomware last Thursday. The decrypter seems to work on most file types - doc, docx, xls and xlsx. I have not got it to work with any pdfs or csv files. There is another problem - it only seems to work in the top level folder - files in any subfolders below the top folder added to the decrypter (Add Folder button) do not seem to be properly decrypted. The files with the correct extensions are created, but they are not readable by the appropriate apps. I am using version 18.104.22.168. Many thanks for your great work.
