What is SilentSpring ransomware? And how does it carry out its attack?

SilentSpring ransomware is another crypto-virus first spotted in the first week of March 2018. SilentSpring, just like most ransomware threats, aims to encrypt files of users to extort money from them. As soon as it invades a targeted system using spam emails, it will start to execute its attack by dropping additional malicious files in the affected system and connect to its Command and Control server to send information about the infected system. It also makes modifications in the Windows Registry to achieve persistence. It then scans the computer for specific file types to encrypt such as:
Once it finds the files with the aforementioned extensions, SilentSpring ransomware encrypts them using a strong and sophisticated encryption algorithm. Then it appends the extension “.Sil3nt5pring” on every encrypted file. Right after that, it opens its ransom note which contains a short message written in Russian:
“Ашыпъкьа Яvиsowшvяе!!!
Страница, которую вы искали в этом блоге, не существует.
Перейдите на “Введение” или используйте вкладку “Список”.
Do not understand Russian? Well then, click to this picture. �”
