The ever-changing ransomware scenery has seen newer distribution techniques, many new viruses and even evolved doxware infections for mobile phones. The ransomware infections are now using services such as Dropbox in which the criminals upload malicious files and post the download link In e-mails instead of uploading e-mail attachments in archives. Instead, different types of files, such as executable SFX archives that are modified to cause infection by auto extracting malicious files. One thing hasn’t changed much however and this is the encryption algorithm. There are still many ransomware viruses that were successfully decrypted in time and we are posting our 5th update with links to decryption instructions of those viruses.
