EXPLAINING WANNACRY AND HOW TO PROTECT YOUR COMPUTER

EXPLAINING WANNACRY AND HOW TO PROTECT YOUR COMPUTER

WannaCry is a current global ransomware cyber-attack that is taking advantage of a Window’s vulnerability known as Elite Blue.   

What Is Malware?

Malware is short for malicious software which can be used to interfere with computer or mobile operating systems (Microsoft Windows, Mac OS X, iOS, Android, etc.) Malware can do anything from gathering sensitive (usually financial) information to holding your files ransom to just displaying annoying ads.

What is Ransomware?

Ransomware is a form of malware that encrypts your information and demands payment to decrypt it Ransomware can encrypt individual files, a computer’s Master File Table, or a hard drive. Hackers create malware to extort money often demanding the victims pay via Bitcoin, an online global money transaction system where identities are anonymous.  Ultimately the victim decides if the hostage information is worth the ransom.

About WannaCry

Typically users have to do something to become infected.  They click on a link, open a file, or connect external hardware.  The WannaCry malware attack is different because it travels through the internet searching for machines that are vulnerable (Elite Blue).  Although Microsoft pushed a fix for the vulnerability last month, not all users have installed the update.  When the malware detects that a machine does not have the update it executes a cryptoviral extortion attack.  Users then get a screen informing them of what happened demanding $300 to decrypt the files.  

So far WannaCry has attacked tens of thousands of computers in over 100 countries and caused a hospital in England to cancel medical procedures.

HOW TO PROTECT YOURSELF FROM WANNACRY
