Londec is a ransomware virus, that encrypts your files (videos, photos, documents). The crypted files can be tracked by “.londec” extension. So, you no longer can obtain access to them.
Here I help you to remove Londec virus without any payment for the removal infection. As additionally I will assist you in restoring your “.londec” files.
What is Londec virus?
“Londec” can be correctly summarized as a common ransomware.
May[/dropcup] be you known, ransomware is a special kind of virus that crypt your files and then forces you to pay the some amount of money to restore them.
Londec belongs to the Djvu (STOP) ransomware family. Its activity is similar to other of the same family: Brusaf, Masok. It modifies all your personal files though encrypting them. As result, you cannot work with your documents. This virus adds “.londec” extension for all crypted files. For example, the file “report.doc” will be renamed to “report.doc.londec”. After encryption Londec drops a specific text file “_readme.txt” and adds it into all folders that contain the encrypted files.
That text file asking for the ransom payment as mentioned here :Djvu family. The summary of the message is that all the files are encrypted and that the only solution to restore them is to use a unique key.
The cryptography mechanism applied by Londec is not completely researched. However, it is definitely true that computer owners whose documents got encrypted may be given a specific decryption key, which is totally and there are no other copies of it that would work solely on your device.
The sad reality is that it is impossible to restore the information without the unique key available.
As long as Londec is performing its malicious activity it is impossible for users to gain access to the key, which is stored on a distant server owned by the criminals who distibute the Londec virus.
The crooks mention that for receiving the key and restoring the amended data, the payment should be implemented in their favor that amounts to $980. To obtain the payment details the victims are encouraged by the message to contact the frauds by writing an email, or via Telegram.
The alert also indicates that the computer owners must get in touch with the Londec representatives during 72 hours starting from the moment of data modification. The notice mentions that on the condition of getting in touch within 72 hours users will be granted a 50% rebate, thus the ransom amount will be minimized down to $490). However, no matter what the demanded amount is, stay away from paying the ransom!
Is it a good idea to pay the Londec ransom?
If you think that paying the requested ransom is the only way-out, I should mention a few thoughts regarding this decision. The criminals who stands behind the Ransomware surely wants you to think that there is definitely no other option to recover the information.
Definitely, the crooks want the ransom to be transferred via some specific pre-defined channels and sequence of steps. As a matter of fact, this is typically done via Bitcoins as the main transfer currency. The application of Bitcoins is generally the preferred option by cyber frauds because such transfers are very unlikely to get traced.
Considering this peculiarity of Bitcoins, they are often applied by hackers that aim to scare the targeted victims through the Ransomware. The technology of such hard-to-trace virtual currency is the main ground why almost all Ransomware frauds manage to remain anonymous after successfully fulfilling their covetous money-stealing missions.
Yet, in many instances, even transferring the requested ransom might not help the virus victims as it is quite possible that they may not be given any file-decryption key. If so, it is a good solution to try some other possible alternatives that might be available – paying the ransom is most certainly not the good way-out and should be the very last item in the list.
You cannot trust online frauds since they aren’t concerned what you feel about the trouble with your files, even when you do initiate the transfer of the ransom. This is why paying the money demanded by these frauds does not really fix your problem. So, often people simply lose their money for nothing.
I certainly recommend that you do not contact these crooks and do not send funds into their wallets. As per now, there are no tools able to crack the Londec ransomware or restore the encrypted data. Thus, the one of the real working solution to recover the lost data – just using the available backups, as long as it is in place.
You should be aware that the Internet today is full of viruses that look pretty similar to the Londec infection. Malicious programs known as ransomware are generally elaborated to encrypt important files and to mention about the ransom on the targeted screen to eventually force people to transfer the ransom figure into the accounts of the crooks that develop such a kind of malware.
The peculiarity of all such ransomware threats is that they apply a similar set of actions for generating the unique decryption key to recover the ciphered data.
Thus, unless the ransomware is still under the stage of development or possesses with some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t really perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.
Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.
For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.
Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.
For this reason, locating the backup on your main device is surely not a wise idea.
How does Londec attack the PC?
Londec refers to various methods to spread its roots into the computer. It is not really clear what exact method was used to infiltrate your PC.
Londec ransomware attack following a successful phishing attempt.
Nevertheless, these are the common leaks through which it may be injected into your PC:

- online free hosting resources;
- using illegal peer-to-peer (P2P) resources for downloading pirated software.
There were cases when the Londec virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing the Londec ransomware manually, by actually making you directly participate in this process.
Surely, the bogus update alert will not indicate that you are going to actually inject the Londec ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.
