WannaCry Ransomware Attacks more than 45,000 Computers in 74 Countries

WannaCry ransomware is in the hype due to the severity of attacks on a wide range of private companies and public organizations located in different countries of the world. The motive behind spreading WannaCry ransomware is to demand money from the companies, as the companies will not be able to unblock systems or files once they get blocked by this massive ransomware. The attackers unblock the access after getting $300 from the victims.

The Modus Operandi of WannaCry Ransomware

WannaCryptor ransomware targets those systems that are vulnerable to NSA’s exploit EternalBlue. Some of the Windows users didn’t update the security patched released by Microsoft in March. The attackers are using this exploit to infect and block access to computers or to its files. Attackers demand $300 to remove the infection from the PCs and to unblock the access. But it is not guaranteed that the access will be unblocked after getting dedicated payment.

If ransomware could infect a single computer in the organization, the entire network gets vulnerable. Therefore, it is not safe to keep even a single computer with outdated security updates. It can stake the entire network security.
