What is MadBit ransomware? And how does it execute its attack?

MadBit ransomware is a file-encrypting malware first observed on December 29, 2017. Based on the analysis made by security researchers, this crypto-malware is actually an original program that features snippets of open-source code. MadBit ransomware is designed to generate a unique pair of encryption and decryption keys – one is used to encrypt the targeted files while the latter is used to restore the encrypted files. The decryption key is then stored in a remote server managed by the cybercriminals behind MadBit ransomware.

Before it starts encrypting the files, MadBit ransomware deletes the shadow volume copies of its targeted files, making it hard for its victims to recover them without the decryption key. During the encryption, this file-encrypting threat uses the AES encryption algorithm in encoding the files. It then adds the .enc extension after every file’s names to mark the encrypted files. After the encryption process, displays an alert which is shown in a message box labeled “madbit encryptor: Hello, you are encrypted!” containing the following text:

“***!WARNING!***

***YOUR COMPUTER ARE INFECTED***

***ALL DATABASES, SITES AND USERS HOME FILES HAVE BEEN ENCRYPTED***

================================================

>>>You have to pay for decryption in Bitcoins. The price depends on how fast you write to us.<<< ***After payment we will send you the decryption tool ,that will decrypt all your files.*** ===FREE DECRYPTION AS GUARANTEE=== ===Before paying you can send to us up to 1 files for free decryption=== Please note: that files must NOT contain valuable information and their total size must be less than 1Mb === Important information === YOUR COMPUTER UID : COPY&SEND YOUR UID TO EMAIL’S :

adaline.lowell.85@mail.ru ================================================ ***!WARNING!*** ===****rnadbit***madbit***madbit***madbit***madbit***madbit***madbit***madbit***madbit****===”

The ransom amount demanded the encrypted files’ decryption varies from the time period during which the victim manages to get in touch with the developers of MadBit ransomware who insist that victims should pay in Bitcoins to keep their anonymity. In addition, if you’re one of the unfortunate victims of MadBit, the crooks encourages you to send one file which must be less than 1MB to see if the decryptor really works. However, it’s obviously only a ploy to get you to pay the ransom. And besides security experts do not advise you to pay the ransom as you would only waste your money and time and that you might only be tricked to pay more than the original ransom amount.

For now, the best thing you could do is to eliminate MadBit ransomware before it causes further damage to your files and use any backup copies you have until security experts are able to develop free decryptor.

How does MadBit ransomware disseminate its malicious file(s)?

It seems that MadBit ransomware uses malicious spam email campaigns in disseminating its malicious files. That’s why you have to be cautious in opening emails even though it seems like they came from well-known companies as cyber crooks tend to pretend that the email is sent by some famous companies or groups to lure users in opening the email and the attachment. The attachment may be a macro-enabled document which contains scripts used to launch the attack on the infected computer.
