For people in both the public and private sector, cyber-attack has become a potentially life-altering and seemingly unstoppable threat that is beginning to define our everyday lives.
In few hours, 200,000 machines were infected. Big organizations were struck and crippled by the attack.

History of ransomware
The first ransomware takes us back to 1989 (that’s 27 years ago). It was called the AIDS Trojan, whose modus operandi seems crude nowadays. It spread via floppy disks and involved sending $189 to a post office box in Panama to pay the ransom.
How times have changed!
The appearance of Bit coin, and evolution of encryption algorithms helped turn ransomware from a minor threat used in cyber vandalism, to a full-fledged money-making machine.
The WannaCry attack is a perfect example of this since it used a wide-spread Windows vulnerability to infect a computer with basically no user interaction.
That’s why each new variant is a bit different from its forerunner. Malware creators incorporate new evasion tactics and pack their “product” with piercing exploit kits, pre-coded software vulnerabilities to target and more.
Ransomware brought extortion to a global scale, and it’s up to all of us, users, business-owners and decision-makers, to disrupt it.
We also know that we’re not powerless and there are a handful of simple things we can do to avoid ransomware.
Stay safe and don’t forget the best protection is always a lot of common sense and keeping offline backups in addition to the online ones!
