Omfl Virus Removal Guide (+Decrypt .omfl files)

Omfl – Ransomware

Omfl is a harmful software application functioning as common ransomware. Michael Gillespie, the well-known virus researcher, first discovered this new name in the DJVU ransomware family.

Omfl was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully accomplished, the users are not able to get access to them. Omfl ransomware includes its own “.omfl” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Omfl, will be titled as “price_list.xls.omfl”. When the file encryption is achieved, Omfl puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.

The alert specified by document requesting the random os really similar to the alerts provided by other ransomware hazards coming from the DJVU family. The caution basically indicates that the information has been encrypted and the only option to get access to it is to use a special standalone key. Regretfully, this statement is definitely true.

The method to secure the files utilized by Omfl is not totally looked into. Nevertheless, there is no doubt that each computer system owner may be provided a special decryption key, which is absolutely unique. It is very tough to recover the information without the appropriate type in location.

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

One more peculiarity of the Omfl infection 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 released the Omfl ransomware into the internet. In order to get the key and bring back the essential information, the users are informed to connect with the frauds through e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals should get in touch with the Omfl authors within 72 hours upon the moment of the information file encryption. The alert indicates that by doing so individuals will acquire a 50% discount, therefore, the ransom quantity falls to $490.

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. For this reason, paying ransom typically does not result in an effective healing. So, the users might just lose their money for absolutely nothing.

Likewise, we urge you not to call the scams as they instruct. Do not transfer cash into their wallets. There are no applications that could break the Omfl ransomware or bring back the data at no charge. Therefore, the only appropriate decision is to bring back the information from possible backups (if available).
