I got a case whereby all my pdf & MS files were encrypted without changing their file type extensions. Trying to open encrypted file will fail with a typical note ' Adobe Reader could not open "filenam.filetype" because it is either not a supported file type or because the file has been damaged.....'
In each folder of the computer including desk top as well as each folder of the attached mobile HD, the following 2 files were added:
1- file 'HELLOWREADME15' which is a text document confirming encrypting the files and giving contacts through: firstname.lastname@example.org * email@example.com * firstname.lastname@example.org
2- file 'HITLERSNASTYLITTLECRYPTER.KEY15' which is an unknown windows file type.
the forum SW "ID Ransomewareould' could not identify the malware yet. Would appreciate if someone could help to id the malware and advise a SW or tool to recover my files.
