WannaCry


⇒  What is WannaCry?

First and foremost, let’s clarify exactly what WannaCry is. This malware is a scary type of trojan virus called “ransomware.” As the name suggests, the virus in effect holds the infected computer hostage and demands that the victim pay a ransom in order to regain access to the files on his or her computer.
  

How can I protect myself from WannaCry?

Regardless of which operating system you run, you should install any and all available security updates immediately. Specifically, Windows users with machines that run Windows XP, Windows 8, or Windows Server 2003 should immediately install this security update released on Friday by Microsoft.

What can I do if my computer is infected with WannaCry?

Sadly, there is no fix for WannaCry available at this time. Antivirus companies and cybersecurity experts are hard at work looking for ways to decrypt files on infected computers, but no means of third-party decryption are available right now. Hopefully affected users have backups of their data available, because the only other option right now is to follow the instructions offered in the software to pay the ransomware





targets for ransomware 


the cyber criminals behind ransomware do no particularly care their victims are,as long as they willing to pay the ransom.with this in mind, it is easy to see why the cyber criminals tend to take a scatter-gun approach to propagating the ransomware , casting a wide net across targeted regions and types of users.with the cyber criminals hitting millions of the users world, if even a small percentage if victims pay the ransom,then it could make the scheme worthwhile.this is why our default recommendation is not to pay the ransom.

Of this number, IPv4 reserves some addresses for special purposes such as   private networks   (~18 million addresses) or   multicast addresses   (~270 million addresses). IPv4 addresses are usually represented in   dot-decimal notation, consisting of four decimal numbers, each ranging from 0 to 255, separated by dots, e.g., 172.16.254.1.
