Koom Virus Removal Guide (+Decrypt .koom files)

Koom Virus – Details

Koom is a harmful software application working as common ransomware. Michael Gillespie, the popular malware researcher, very first discovered this new name in the DJVU ransomware family.

Koom was created for the sole function to encrypt all popular file types. Logically, as soon as the file encryption is effectively accomplished, the users are not able to get access to them. Koom ransomware adds its own “.koom” to all the encrypted files. For example, the file “price_list.xls”, when modified by Koom, will be entitled as “price_list.xls.koom”. As soon as the file encryption is accomplished, Koom puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.

The alert stated by _readme.txt requesting for the random os really comparable to the notifications offered by other ransomware risks coming from the DJVU family. The caution basically shows that the files have been secured and the only option to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely true.

The approach to secure the files used by Koom is not totally investigated. However, there is no doubt that each computer owner may be provided an unique decryption key, which is absolutely special. It is extremely difficult to recuperate the data without the suitable type in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Koom ransomware 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 actually released the Koom infection into the internet. In order to acquire the key and restore the crucial information, the users are informed to contact the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people ought to contact the Koom authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so individuals will obtain a 50% discount rate, for that reason, the ransom quantity falls to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no assurance that these online crooks will keep their promises, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Hence, paying ransom typically does not lead to a successful recovery. So, the users might simply lose their money for absolutely nothing.

Likewise, we advise you not to get in touch with the scams as they instruct. Do not transfer money into their wallets. There are no applications that could crack the Koom virus or restore the data for free. For that reason, the only appropriate choice is to bring back the information from possible backups (if available).
