Ofww – Ransomware
Ofww is a malicious software functioning as typical ransomware. Michael Gillespie, the well-known malware researcher, first found this new name in the DJVU ransomware family.
Ofww was created for the sole function to encrypt all popular file types. Logically, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Ofww ransomware adds its own “.ofww” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Ofww, will be titled as “price_list.xls.ofww”. When the file encryption is achieved, Ofww puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.
The message specified by text file asking for the random os extremely comparable to the notifications given by other ransomware threats belonging to the DJVU family. The warning basically indicates that the data has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is definitely real.
The method to secure the files utilized by Ofww is not completely researched. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is absolutely unique. It is extremely tough to recover the information without the appropriate key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Ofww virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have introduced the Ofww virus into the world wide web.
