Madek is a new name in the kind of ransomware-type infections. The virus currently attacks computes and encrypts your files. The files modified by it can be tracked by .madek extension. Thus, you no longer can open them.
This article specifically aims to help you remove Madek virus without the need to initiate any payment for the removal infection. As additionally I will assist you in restoring your “.madek” documents.
How damaging is Madek ransomware?
Madek can be correctly summarized as a typical ransomware-type infection.
Ransomware stands for a special kind of program that introduces unwanted alterations with your documents and then forces you to pay to restore them. Madek was first revealed and discovered by Michael Gillespie1.
Madek belongs to the Djvu ransomware family. Its activity is basically similar to other representatives of the same family: Gehad, Vusad, Berosuce. It modifies all common file types though encrypting them. Hence, users cannot work with the files as soon as they are encrypted. Madek adds its particular “.madek” extension into all file modified by it. For example, the file “report.doc”, once ciphered by Madek, will be changed into “report.doc.madek”. As soon as the encryption is successfully accomplished, Madek creates a specific text document (“_readme.txt”) and adds it into all folders that contain the encrypted files.
The text file generated by Madek asking for the ransom payment is basically similar to other notifications mentioned by the ransomware belonging to the Djvu family. The summary of the alert is that all the documents are encrypted and that the only solution to restore them is to use a unique decryption key.
The cryptography mechanism applied by Madek is not completely researched. However, it is absolutely true that computer owners whose files got encrypted may be given a specific decryption key, which is totally unique and there are no other copies of it that would work solely on your device. The sad reality is that it is impossible to recover the information without the unique key available.
Once Madek is performing its malicious activity it is impossible for you to gain access to the key, which is stored on a remote server owned by the frauds who promote the Madek 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 Madek 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 Madek 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.
It is clear that 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 crooks because such transfers are very unlikely to get traced.
Considering this peculiarity of Bitcoins, they are applied by criminals that aim to scare the targeted victims through the Ransomware. The technology of such hard-to-trace virtual currency is key factor why almost all Ransomware criminals 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 strongly advise that you do not contact these crooks and do not send funds into their electronic wallets. As per now, there are no tools able to crack the Madek ransomware or restore the encrypted data. Thus, the one of the real working solution to recover the lost data – just using the available backups.
You should be aware that the web today is full of threats that look pretty similar to the Madek infection. Malicious programs known as ransomware are typically 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 computer is surely not a good idea.
How does Madek attack the PC?
Madek refers to various methods to spread its roots into the system. It is not really clear what exact method was used to infiltrate your PC.
Madek ransomware attack following a successful phishing attempt.
Nevertheless, these are the common leaks through which it may be injected into your PC:
- hidden installation along with other apps, especially the utilities that work as freeware or shareware;
- dubious link in spam emails leading to the Madek installer
- online free hosting resources;
- using illegal peer-to-peer (P2P) resources for downloading pirated software.
There were cases when the Madek 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 Madek 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 Madek ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.
Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Madek ransomware.
To sum up, what can you do to avoid the injection of the Madek ransomware into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Madek penetration. You must be cautious while installing free software today.

The message by the Madek ransomware states the following frustrating information:
