At the beginning of the year McAfee release a document laying out there predictions for cyber security. And with it being almost half way through the year I feel it would be appropriate to write a review on how there predictions are coming on and if they are coming true.

The initial part of the document I am going to cover is the prediction that “Ransomware subsides in the second half of 2017” For those that don’t know ransomware is a type of malware essentially take control of the users data until the demands or ransom are met. and it is becoming a much greater issues, there have even been cases of not just PC’s but also mobile devices being effected by ransomware. And although the measures to stop these types of attacks are improving the methods for delivering these attacks is also becoming an issue. This could be in the form of using multiple vulnerability to achieve the final goal.  These current point of Internets to the Ransomware attacks are:

  • Adobe Flash
  • Microsoft Internet Explorer and Edge browser
  • Java, PDS and Microsoft office
  • Windows Kernel
  • Infrastructure software
  • Virtualization software
  • Security Products

But McAfee’s prediction of ransomware reducing by the second half of the year could look to be incorrect, this is because of a recent attack that has effected the NHS (British National Health Services) There where a number of services effected including a number of Hospitals, Pharmacy’s and GP Surgery’s. The attack was encrypting data and then demanding £230 to decrypt the files. This could have had a massive effect on the health and live of real people. Usually when you see a large scale cyber attack it is on large organization and companies that do not literally have peoples lives in there hands. This attack could have lead people dying.

The attack is called WannaCry worm and how was it so effective. Well it is rumored to have used some exploits that where found when a large number of NSA documents where leaked earlier this year. These leaks where called Vault 7 that detailed a number of exploits that the NSA had been finding and collecting .

How the WanaCry worm works, is when it finds a vulnerability machine on a network  it will infect that machine and sit and wait until it can find more vulnerable machines on the network and then it will keep the processes going until as many machines as it can infect are infected. From there there could be a trigger for the attack to start or it could open up the infected machines to more complicated attacks, this could be in the form of allowing malicious files to be download to the machine or it could simply be that the worm will in fact deploy the ransomware attack.

There have been reports all over the world in the past few days about large scale attack of this nature, so is this the end or is it only going to get worse?
