From WannaCry to Petya

As with WannaCry

the Petya computer virus mainly affects the most commonly used operating system. The wave of cyber attacks on a global scale that was detected this Tuesday uses a vulnerability of Windows for which Microsoft had already published a security patch. The US company has acknowledged that the first attack was directed at Ukraine.

The virus "uses several techniques for its propagation, including one that has already been addressed in a security update available for any system, from Windows XP to Windows 10, called MS17-010"

Following the previous cyberattack produced by WannaCry in May, Microsoft advised its customers and users to install the MS17-010 patch. The failure and ways to capitalize have already been made known in a series of materials 'hacked' to the US security agency.

However, Microsoft has said it will continue to investigate the problem, while saying that it will take "the necessary measures to protect its customers". Sources from the US firm have cautioned against opening unknown files since such "ransomware" attacks or data hijacking generally use e-mail messages to propagate.

Although the authorship of cyberattack is still unknown, computer security experts believe that the origin lies in Ukraine. The firm Cisco points out that "some infections are related to the accounting software updates" used in that country called MeDoc

In 30 seconds you can infect computer systems around the world

Alejandro Suárez, an expert in the field of new technologies, has confirmed that the cyber attack that affected companies around the world was due to the existence of "a security hole in Windows systems" Which cybercriminals have exploited to "put a virus that is much more sophisticated than the previous one and much less than the next", because it is convinced that attacks of this type will repeat themselves.

Network expert and collaborator of "The Flashlight" warns that software "can be manipulated, modified and replicated in 30 seconds and people around the world take advantage of those gaps to infect systems around the world."

According to Suárez, in Spain there is an important number of critical infrastructures, such as power plants, water control, traffic lights; "We have a high technological dependence", but prepared to repel an attack of this type "we do not have personnel, resources, or budgets to guarantee the protection"

My personal opinion: Use linux, maybe you have heard that linux has been harm by this viruses but that's a mayor lie or a misunderstanding about technology. Linux can run samba servers, it can host the virus but can't be affected by it ... It's like being a carrier of the hiv virus you can infect others but it can't harm you ...

I wonder who takes the decision of running a power plant in proprietary software that's plane stupid
