It is well known that humans are the weakest link in the information security chain, but specifically, who are them? Well, you may guess, “they” are everyone. I have been in both sides, as a user and as a system admin; and in both sceneries humans tend to make mistakes. It’s human nature.
WannaCry or Wanna Decrytor ransomware is an informatic virus that attacks Windows operating system based computers primarily (including servers) by taking advantage of system vulnerabilities exploited by Eternalblue, a tool believed to be developed by the USA National Security Agency. What is the unique effect once infected by the virus? Well, you will notice it fast. The system will show you a Popup window letting you know that your computer is infected, all your files are encrypted, and for you to recover it all, they require a ransom payment using bitcoins. Unless you make the payment, all your files will stay encrypted. The worst thing about this virus is that, if you do not pay in a certain period, the ransom payment will keep rising.
But, wait! The intention of this article is not to create panic. Even though you should panic if your computer got infected and you didn't backed up your files recently (last day or night before the infection).
