Iios – Ransomware
Iios is a malicious software functioning as common ransomware. Michael Gillespie, the widely known malware researcher, first found this new name in the DJVU ransomware family.
Iios was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the file encryption is successfully accomplished, the users are not able to get access to them. Iios ransomware includes its own “.iios” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Iios, will be titled as “price_list.xls.iios”. When the file encryption is achieved, Iios puts its own distinct text file (_readme.txt) into all the folders that save the encrypted files.
The alert specified by _readme.txt asking for the random os extremely comparable to the notifications given by other ransomware dangers coming from the DJVU family. The caution basically shows that the information has been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.
The technique to encrypt the files used by Iios is not totally looked into. Nevertheless, there is no doubt that each computer owner might be provided a special decryption key, which is definitely unique. It is extremely difficult to recover the information without the suitable type in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Iios virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the crooks who have introduced the Iios infection into the internet. In order to obtain the key and restore the important data, the users are told to get in touch with the frauds by means of e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise states that individuals must call the Iios authors within 72 hours upon the moment of the data encryption. The alert shows that by doing so the people will obtain a 50% discount rate, for that reason, the ransom amount drops down to $490.
