Rising to the international level of hacking, we find that the state player are doing the dirty job. Their malware is so sophisticated that countering it is almot imposible. It is believed by experts in this field that the People' Republic of China is the real deadly culprit. Hackers are state players and their targets are the high profile government ministries of countries that may one day go to war with China.
India is very vulnerable. Although our specialists in the Corps of Signals are confident that the commander's orders to soldiers will be transmitted unhindered, other experts demur. USA is not safe either.
What will happen on the international scene if a full fledged war breaks out? Well, the US and China will be the main adversaries with their minor allies in toe. The danger lies in cyber war escalating and besides military etablishments, civilian outfits like hospitals and school could be dragged in. If the malware that cripples the system of Internet communication is too strong, there is no device, as of now, to top it short of a hospital or a school. The damage to non-military establihment will be colossal.
Undoubtedly the cyber war was fought on a big scale in the past too. The US had disrupted the nuclear programmes of Iran in 2010. STUXNET virus was deployed by both the US and Israel and their operation was quite successful. Syria and Serbia were also subjected to successful attacks by the US. China has been hacking computers for government secrets and also for economically paralying its adversaries. No antidote is in evidence to fight against the international hackers.
