Londec Virus Removal Guide (+Decrypt .londec files)

Londec Virus Ransomware

Londec is a malicious software application working as typical ransomware. Michael Gillespie, the well-known malware researcher, very first discovered this new name in the DJVU ransomware family.

Londec was created for the sole function to encrypt all popular file types. Realistically, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Londec virus adds its own “.londec” to all the encrypted data. For instance, the file “price_list.xls”, as soon as modified by Londec, will be entitled as “price_list.xls.londec”. When the file encryption is achieved, Londec puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.

The alert stated by text file requesting the random os extremely comparable to the notices provided by other ransomware hazards belonging to the DJVU family. The warning generally indicates that the files have been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.

The method to secure the files utilized by Londec is not entirely looked into. However, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely special. It is exceptionally hard to recuperate 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 Londec ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have introduced the Londec virus into the internet. In order to get the key and bring back the crucial information, the users are informed to get in touch with the scams by means of email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that the people must contact the Londec authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so the people will acquire a 50% discount rate, for that reason, the ransom amount 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 assurance that these online criminals will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom frequently does not lead to a successful recovery. So, the users may just lose their money for absolutely nothing.

Similarly, we urge you not to contact the scams as they advise. Do not transfer loan into their wallets. There are no applications that could crack the Londec ransomware or bring back the information at no charge. Therefore, the only proper decision is to bring back the data from possible backups (if offered).
