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

Madek Ransomware

Madek ransomware is a new crypto-malware designed to encrypt files to extort money from victims. As per the analysis done by security experts, it seems that this new crypto-malware is a new variant of Djvu/STOP ransomware. Its corrupted files can be recognized by the .madek extension appended at the end of the affected files’ names.

Once Madek ransomware is able to infiltrate a targeted system, it will start to implement its attack by initiating a sequence of malicious actions. It will first connect to its Command and Control or C&C server in order to download additional malicious files it needs in its attack. These malicious files may be placed on essential Windows system folders like %AppData%, %Temp%, %Roaming%, %Common% and %System32%. After that, it will begin encrypting files using a sophisticated encryption algorithm. Following data encryption, it opens a text file named “_readme.txt” that states:

“ATTENTION!
Don’t worry, you can return all your files!
All your files like photos, databases, documents, and other important are encrypted with the strongest encryption and unique key.
