The attack that caused panic worldwide was made using the ‘ransomware‘ mode, which blocks computers, telephones, and other electronic devices. In order to encrypt the information, they store. It is something very similar to a kidnapping. Because it has similar conditions: the user is unable to access the data, since they are encrypted. I.e. have an invulnerable security code, which can be considered as a kidnapping. In addition, the person appears a message on the screen that indicates payment instructions, to retrieve the files.
It is estimated that the attack affected about 200,000 computers in the world, according to data from The New York Times. In Colombia, the Government has already taken measures, such as the provision of line 018000910747, in which information on threats of cyber-attacks can be requested.
There have already been other scandalous cyber-attacks in history. Such as hacking 77 million Play Station accounts, which resulted in losses of $171 million. The attack on the dating page Ashley Madison, who stole Information about the private life of the users and then bribed them. Many marriages went ‘to the trash’ and users demanded the portal. The figures of legal actions against the company are estimated at $151 million dollars.
How Wanna Cry cyberattack spread
The way in which the ‘Wanna Cry cyberattack’ spreads is through emails, which contain attachments arranged to contaminate more computers. Once people open these documents, the virus exploits a flaw in the Windows operating system. Especially on computers that handle old versions, to access databases, work documents and all kinds of important data.
The computer is completely infected, even its extensions such as USB memories or removable disks. Microsoft Windows had already warned of the vulnerability of older versions of the operating system. That is still used in most companies, and even offered a patch to fix it.
Speech From Bill Gates
Due to the event, Bill Gate’s company in Colombia gave a statement in which he stated: “our engineers incorporated detection and protection against new malware known as Ransom: Win 32. Encrypt the computers that are running our Free antivirus software, and have Windows Update enabled, are protected. “So, if you have Windows updates up to date, you do not have to worry.
Although this has been the most controversial attack, threats of this type have remained on the radar of companies. According to Kaspersky Lab, companies dedicated to computer security with an international presence. In 2017 there were 702 million attempts to exploit exploits, a malware that makes use of software errors to propagate malicious code such as ransomware or Trojans.

* Choose a software vendor who is responsible for vulnerability issues.
* In a network of PCs, you can opt for patch management solutions, which allow software updates on all terminals.
* Verify that your security programs have to exploit prevention mechanisms.
The Center for Security and Digital Surveillance of the company of computer security A3SEC, like measures of protection the following:
* Download a trial version of Insight VM (a kind of virus scanner), to identify if there are vulnerable computers, you can find it from google.
* Stay updated through social networks on new ways to solve the problem.
* Follow the project NoMoreRansom.org, which has updated information on security and kidnapped files.
