Cyber attacks against western countries from North Korea are seemingly impossible to stop. The cyber danger is far more severe than previously thought. Through its hacking attempts on western countries important Infrastructures, it surely has created panic and chaos in the country. Along with all important security systems and financial systems, hacking attacks have increased many folds on regular networks creating huge disorder and confusion among the people.
One of the important factors for North Korean hackers is the least risk of retaliation, the country is already facing growing list of Sanctions imposed on the state making it one of the most isolated country in the world. Thus, making North Korea least vulnerable for punishment or outcast from the other states.
Tracking the hackers and strengthening cyber defence mechanism is not easy to implement as most of the attacks do not originate from the North Korean soil. Lots of attacks originate from Malaysia, Nepal, Kenya, New Zealand, China and other countries.
Severity Of the attacks can be assumed from the fact that last year North Korea was able to steal millions of dollars through ransomware.Last year a very popular attack "Wanna cry" affected almost 150 countries around the world and almost 200000 systems were infected including hospitals, financial institutions, companies, security systems, blood banks, and other infrastructures around the world.
The health sector in England and Scotland were badly affected.70,000 devices including computers, MRI scanners, blood storage refrigerators and theatre equipment were hacked in National health services hospitals. Many of the ambulances were redirected and many non-emergency patients had to turn away.
There is one more famous attack on Sony Pictures Entertainment which disrupted the release of the movie "The Interview" causing the company huge financial loss.
There have been increasing cyber attacks around the world and the large extent of accusation is directed to North Korea.
Not Only government infrastructures but also regular system users and companies are under threat of hacking. North Korean hackers have cracked several games and software and digital banks. In One of the cyber attacks on Tien Phong bank in Vietnam, hackers tried to steal $1.13 million.There was an attack on South Korean Bitcoin Exchange and hackers were successful in stealing data of 30,000 customers, and bitcoin of worth $870,000.
