How to Prevent WannaCry infection?
1. Make sure that all hosts have enabled endpoint anti-malware solutions. 2. Install the official Windows patch (MS17-010), which closes the SMB Server vulnerability used in this ransomware attack. 3. Scan all systems. After detecting the malware attack as MEM:Trojan.Win64.EquationDrug.gen, reboot the system. Make sure MS17-010 patches are installed. 4. Backup all important data to an external hard drive or cloud storage service.
