What is French101 ransomware? And how does it carry out its attack?
French101 ransomware is a data-encrypting malware discovered by “Petrovic”, a security researcher. This new crypto-malware targets important data in a computer and uses a “.french101” extension in marking its encrypted files. Once it infects a computer, it will carry out numerous changes in the system. It starts by connecting to a remote server controlled by the attackers. It is where its other components are downloaded, after which will be placed on several system folders. These components are used to launch or suppress system processes as well as modify the Windows Registry so it can automatically run on system boot. Once the system modifications are completed, it proceeds to find its targeted files.
After it finds the targeted files, it will begin the encryption procedure using a sophisticated encryption algorithm that would make the files inaccessible to users as the encryption modifies the files with a symmetric key. This entails a single key that could decrypt and encrypt the affected files. However, this key itself is usually encrypted with asymmetric encryption and only the developers of French101 ransomware have access to it. French101 ransomware appends the .french101 to the affected files to mark them. It then delivers a ransom note in a text file named “HOW TO RECOVER ENCRYPTED FILES.txt” which is placed on the desktop of the infected computer. This ransom note contains the following message:
“Your files are now encrypted!
Your personal identifier:
