Top Ransomware events in recent history

Remember the good old days when the worst thing that could happen with your computer was a silly virus that’ll just send an annoying to a bunch of your friends? Guess what, nobody reads the annoying mails anymore and the viruses have taken a turn for the worse.

Our computers hold every piece of information we have. From important files to cat videos, every thing is on our screens and every transaction is online. This is why Ransomware started in 1996 and with the evolution of bitcoin, became an actual threat around 2013.

A Ransomware allows a hacker to get into your file system and lock your files and devices with an encryption key. The decryption is offered to the victim only on the exchange of a ransom, subsequently giving the victim the access to their own files. Protecting your PC is becoming difficult even if you have an updated anti virus – and that is why you need to invest in the right security controls more than ever today.

The Top Ransomware Concerns Today

These are the recent ransomware concerns that you need to know.

Over the years, these threats have grown bigger, affecting companies at once. Here are the top ransomware events in the recent history:

  • Petya

In the year of 2016, the month of April saw a new low in the history of Ransomwares. The malware attacked the kernels of the Windows systems itself, instead of attacking the files on it one by one. As a result, the victims weren’t able to even boot their system, let alone work on it. The virus was defeated when an algorithm to generate the decryption passwords was released.

  • CryptXXX 3.0

CryptXXX 3.0, which was being used by Neutrino Exploit kit, hit the computer systems with programs as simple as Adobe flash players. The malware used an algorithm that could easily gather the credentials of the victim, giving the hackers the full advantage of draining someone’s bank account after their refusal to pay ransom.

  • Locky

The Necurs botnet that used to send the Dridex Trojan, Locky is an aggressive malware that was used to send spam emails to everyone with auto-download attachments that had the ransomware payload. However, the effects of the same can be reduced if the victim acts fast. The malware used the C&C infrastructure of the for the encryption process, stopping which puts an end to the process.

  • WannaCry ransomware

One of the worst ransomwares of recent times, the month of May this year saw a worldwide release of Wannacry, stopping most Windows systems in its tracks by encrypting all the data on the computer after negating the existence of a domain name called “kill switch”. Exploitation of the vulnerable SMB ports were the cause of the attack, with systems which were not updated with Microsoft’s security update being affected the most.
