Last week reports emerged of the UK government confirming their suspicions of WannaCry being a state sponsored attack involving North Korea.

Earlier this year, just after WannaCry came to prominence I wrote an article What is WannaCry.  In which I speculated due to the nature and style of attack, it did not appear to follow the traditional Ransomware style. What I mean by this is, from the outset WannaCry was targeting and effecting core infrastructure as well as the Public sector in the UK. Resulting in WannaCry becoming somewhat of a disruption, as a rule Ransomware attacker aim to make the process of decrypting the data as smooth and straight forward for the victims as possible. This is likely due to them being after one thing, money. Mozilla conducted an investigation as part of there Online Life is Real Life podcast series a from their investigation they rated Ransomaware customer services. This highlights how the process of ransomware cannot be to complicated as it will reduce and limited their overall ability to collect the ransom

But there are numerous article floating around the web that indicate WannaCry made between $20,000 – $100,000. For an attack of this level that impacted hundreds of thousand of people it was a very poor take.
But the level of chaos and “denial of service” that WannaCry caused indicated to myself that their was more to it than just the money. I am aware that the traditional sence a denial of service or DDoS is targeting web services and flooding them with packets. But in this case WannaCry effected ATM machine as well as computer within hospitals, effectively denying service to them.

Of course the North Koreans released a statement to the effect of them having no involvement and that these accusations are nothing but wild speculation. But it is important to consider that this “speculation” was floating around from the beginning of WannaCry and was stated by a number of security research teams that looked into WannaCry. As well as this, the UK government would not make these accusations without a substantial level of evidence.

The north Koreans have in te past been accused of other attacks, mainly the attack on Sony. This attack was alleged to have happened due to the upcoming release of movie The Interview.

Please let me know your views on the North Koreans involvment in WannaCry in the comments below.
