When Zhao Yi mentioned that the hacking stuff had 'too much destructive power,' Professor Liu just smiled, his eyes looking like he was watching a child playing with a new toy.
Most 'little hackers' are like this.
When using hacking software, or by using tools to steal passwords and accounts, they get a feeling of being 'so awesome', but in fact, it's really no big deal.
Nowadays, domestic networks are just being built, and their security can't be said to be very high. To describe them as riddled with loopholes might be an exaggeration, but the lack of security knowledge among most users is also an important factor causing the security issue.
For example, a family just built a house, completely unaware of security precautions, leaving farming tools and chickens and ducks outside the house, with just a small fence serving as the boundary of their yard.
Outsiders could easily steal many things just by crossing the fence.
