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

Locdoor ransomware is a crypto-malware that’s still under its development phase so it isn’t clear yet if it can actually encrypt files in a computer. Locdoor ransomware also goes by the name DryCry ransomware. Once it infects a computer, it will drop its malicious payload in the system and implement a series of commands in the system in order to connect it to a Command and Control server controlled remotely by the attackers.

After the malicious payload is dropped, it downloads more of its malicious components from the remote server and puts them into system folders. It then makes entries in the Windows Registry so that it can run automatically with each start of the infected computer. It could also launch or repress processes in the Windows environment. Following these changes in the system, Locdoor ransomware supposedly starts the encryption and then displays its ransom in an image stating:
