Ogdo Virus Removal Guide (+Decrypt .ogdo files)

Ogdo Virus – Details

Ogdo is a malicious software functioning as common ransomware. Michael Gillespie, the well-known virus researcher, very first found this new name in the DJVU ransomware family.

Ogdo was developed for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Ogdo ransomware includes its own “.ogdo” to all the encrypted files. For example, the file “price_list.xls”, once modified by Ogdo, will be entitled as “price_list.xls.ogdo”. Once the file encryption is achieved, Ogdo puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.

The alert stated by document requesting the random os very comparable to the alerts given by other ransomware risks 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 a special standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files used by Ogdo is not completely looked into. However, there is no doubt that each computer owner may be released an unique decryption key, which is absolutely special. It is incredibly tough to recuperate the information without the suitable type in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Ogdo ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have actually launched the Ogdo virus into the web. In order to get the key and bring back the essential information, the users are told to connect with the scams through email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people must contact the Ogdo authors within 72 hours upon the minute of the information file encryption. The alert suggests that by doing so individuals will obtain a 50% discount rate, therefore, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online criminals will keep their promises, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom often does not lead to a successful healing. So, the users may just lose their money for nothing.

Similarly, we urge you not to call the scams as they advise. Do not transfer loan into their wallets. There are no applications that could split the Ogdo ransomware or bring back the information at no cost. Therefore, the only right choice is to restore the data from possible backups (if offered).
