What is Enc_robbinhood ransomware? And how does it implement its attack?

Enc_robbinhood ransomware is one of the file-encrypting threats discovered in the last week of March 2019. It stealthily infiltrates your computer and encrypts various stored data, especially the important ones, and hold them hostage in exchange for a ransom. As of the moment, there isn’t a lot of information regarding this ransomware as it is still new so the chances of getting an insight into the origin of the threat are slim.

Enc_robbinhood Ransomware

As soon as its malicious payload is dropped in the system, Enc_robbinhood establishes a connection to a remote Command and Control or C & C server where it downloads additional components. The downloaded components are then placed on system folders in order to launch and repress system processes. It also employs a data gathering module to collect sensitive data in the system as well as the stealth protection module to use the gathered data to evade security and antivirus programs installed in the computer that could interfere with its attack. In addition, it also alters some registry keys and sub-keys like Run and RunOnce so that it can run automatically in every system boot.

After it completes modifying system settings, Enc_robbinhood ransomware will begin encrypting important files in the system using a sophisticated encryption algorithm. Following file encryption, it adds the .enc_robbinhood suffix to every affected file and opens a program window that contains the following message:
