Recently, a computer virus called “WannaCry” hit about 100 countries worldwide. With computer security agencies taking responsive measures, the attack has weakened. Actually, the virus is not totally new—it used the EternalBlue exploit developed by the United States’ National Security Agency that was stolen by hackers.
The incident teaches us at least two lessons. First, there is nothing absolutely safe in the Internet age. Even if developed by law enforcers, a powerful computer attack tool is at risk of being acquired by lawbreakers.
In early 2016, there was a debate between the US Federal Bureau of Investigation and some Internet companies over the question of whether electronic device producers should leave a “backdoor” for legal enforcers to better strike at terrorists. Now we have the answer—No.
No one can ensure that such a“backdoor” will never be used by lawbreakers and the best choice is not to open such a door in the first place.
