Analysis Report on the WannaCry Sample

The sample exploits the ETERNALBLUE SMB vulnerability or DOUBLEPULSAR backdoor for propagation and infection of the ransomware. The sample first connects to the domain name http://www.iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com, to test network connectivity. If the network is reachable, the sample exits; otherwise, the sample carries out subsequent behaviors. Therefore, a reachable domain name can be registered to stop further attacks.
