“Virus disasters” are commonly referred to incidents where more than 25 computers are infected on the same network with a virus. This label applies to recent WannaCry attacks that close all files on infected computers until the user pays a ransom to reopen them.

The health sector in the UK was one of the first to be hit by these attacks, but later spread to many institutions around the world.

Ray Pompon, security researcher at F5 Networks, said: “The risk of new attacks according to F5 Networks is that they are largely focused on the health sector, so the complications of these attacks may cause some patients to die (due to inability) Of access to their files), which also classifies these attacks as electronic killings, a dangerous precedent in this area.

These attacks have focused on the SMB protocol for data sharing, which is often wide open within enterprise networks, contributing to the spread of new attacks on a large scale and rapidly.

Installing the operating system updates is the most important step in protecting against these attacks. However, a second layer of protection can be used to stop data traffic from both the Internet and data transmitted over the network, 22, 23, 3389, 139 and 145, as well as UDP ports 137 and 138, in addition to the need for data backup.
