Impact of the attack – ($$$) and Consequences



The impact is huge as it is one of the leading automobile manufacturer. The amount asked is around $500 to restore the access. The company fixed the vulnerabilities and the tools that are related by the shadow brokers



The amount that was asked from the companies are from $300 to $600 for 3 days and 7 days basis respectively. The companies then uses the required patches that are released by Microsoft to prevent the further attacks and vulnerabilities.

As a process
The process of wannacry ransomware is very simple in general. The attacker’s first search for the victims those are using old and out dated operating system. The old operating systems are often the infected system which is easy to exploit and the wannacry attacker’s main target are those device which are infected and where the security is less. After exploiting the device the attackers first encrypt the data that are in the device (Kao and Hsiao, 2018). After encrypting the data they ask ransom amount of money from the victim. The amount is basically of $300 and $600. After the victim pay the money using bitcoin which is also a crypto currency. When the ransome amount is given then the user get back his access to his/ her data. The operating systems that passed the validity of its own are mainly in the target because an operation system that is past its end of life has no security and many security loop wholes which is prone to be vulnerable (Mohurle & Patil, 2017). The wannacry attackers installed backdoors on the device that are infected and then do the next steps for the ransomware attacks. 
The hackers and the creators of the WannaCry Ransomware Attack attacks the the windows devices that are vulnerable, it already discussed earlier. The NSA developed a malware to exploit the world by using the DoublePulsar backdoor malware and by EternalBlue SMB exploit for the installation of wannacry on the windows systems. EternalBlue is a piggybank system which is the main thing behind this attack. EternalBlue and SMB protocols are exploit the windows systems (Chen and Bridges, 2017). EternalBlue.exe runs a script which targets the Windows computers to executing by using following commands:

SMB echo request is sent to the targeted machine
Environment is set up to exploit the system which is vulnerable
Fingerprinting of SMB protocol is completed
An attempt is made to exploit
If the attack is successful, then DoublePulsar malware s being checked
DoublePulsar pinged for a reply from SMB

The doublePulsar is a tool which bypass the measurement of authentication of a system and then creates a backdoor which allows the remote access. The DoublePulsar fully transfers the system of victims control to the hacker without even
