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

FilesLocker ransomware is a data-encrypting threat that is being distributed as a Ransomware as a Service or RaaS. It mostly targets Chinese and English-speaking users based on its ransom note that is both written in Chinese and English languages. At the time of writing, it may look like a standard small little C# ransomware with little or no distribution. It also turns out that this ransomware is being offered as RaaS where anyone can sign up and earn commissions. According to researchers, this crypto-malware is offering those who sign up as an affiliate a 60% revenue share of all the ransom payments so if the affiliate can drive enough traffic, the commission can go high as 75%.

Moreover, the RaaS also claims to have numerous features you would expect like customization, tracking, strong encryption as well as clearing of the shadow volume copies of targeted files. Aside from these aforementioned capabilities, here are other characteristics of this RaaS.

  • This crypto-malware can operate on Windows XP~Windows 10 with NET 4.0, 32-bit and 64-bit Windows Server.
  • There is no server required.
  • Chinese and English blackmail and dual language interface are used.
  • It creates a bilingual blackmail letter on the desktop and on each disk.
  • It has intuitive background statistics, you can view countries, systems, browsers, etc.
  • It encrypt files with RSA 2048+AES algorithm, no one can crack around the world
  • It also executes vssadmin.exe to delete all shadow copies
  • It can be properly encrypted in a broken network environment, but can not send statistics to the panel
  • Ransomous windows cannot be closed unless third-party tools are used

Based on the analysis done by security experts, FilesLocker ransomware is a fully functional crypto-malware which includes an embedded public encryption key used to encrypt the generated key to encrypt victims’ files. Once it encrypts files, it targets files from specific folders like Documents, Desktop, Pictures, Music, and so on. It uses both AES and RSA ciphers in encrypting files and appends the .locked extension to each one of them. After the encryption, it opens a program window which contains the ransom note that states:
