WannaCry is ransomware that infects itself by abusing a vulnerability in the Windows Server Message Block (SMB) protocol that enables the communication between Windows machines on a network, and specially crafted packets could trick Microsoft’s implementation into effecting an attacker’s code.
2. How did WannaCry Spread?
The wannacry, outspread by abusing windows security weakness over the Internet, managed to infect 230,000 people around the world with ransomware. The self-activating potentiality to spread itself to other systems via connected devices that are infected has caused the peril to soar to the degree of calamity. Even if the first attack wave is countered, if the self-renewed subsequent version attacks are not taken seriously, and the indispensable deeds are not taken, the information saved in the first wave can be permanently lost.

Wannacry, which is infected by abusing windows security vulnerability over the Internet, has started to spread via e-mail after this vulnerability is secured. Wannacry software has also infected the internal networks of corporate companies, with links to email and malicious content. Cyber Threat Intelligence firms have announced that the real big danger will begin with the infection of corporate networks.
