"What do you think?" Officer Yang looked at him.
Su Dong nodded, then shook his head." I have some ideas, but I need to verify them."”
"Are you sure there's nothing wrong with the hotel system?”
The university professor snorted." I guarantee with my reputation that there are no backdoors or viruses left behind by hackers in the computer.”
That was it.
Su Dong nodded in understanding. Then, he walked out of the door," I'm going out for a while. Please wait for me."”
"Oh right, give me a walkie-talkie. It'll be easier to contact me later.”
Everyone: "???"
Officer Li frowned." Old Yang, is this foreign aid reliable?”
Officer Yang looked relaxed." Just give it a try. Anyway, you guys don't have any ideas now, and it won't take long.”
After saying that, the group of people started chatting and began to discuss how hackers did it.
At this moment, the IT manager's expression changed." Oh no, the network is cut off again!”
Officer Li immediately walked forward and looked at the computer's homepage." It's broken again?! Didn't it just break half an hour ago?! Why did it break again?"
"That's impossible. There's clearly no backdoor or virus software.!”
Everyone was puzzled.
At this moment, Su Dong's voice came from the walkie-talkie," Hey, hey, hey, this is Su Dong. How's the hotel's internet?" Did it break again?"
Officer Yang frowned." Yes, it's broken again. I don't know what happened. In the past, it would stop every two hours. This time, it stopped earlier than usual. It stopped only half an hour ago.”
A few seconds later, Su Dong asked again,"How is it now?"”
"Now?" Officer Yang was stunned." Didn't I tell you? The internet is down."
"I've recovered!" The IT manager looked at the computer and said excitedly," The Internet can be accessed again.”
Officer Yang: "???"
Officer Li: "???"
University professor: "???"
What was going on? It had only been broken for less than a minute, and it had already recovered?!
"What about now?" Su Dong's voice came from the walkie-talkie again.
The IT manager failed to refresh the network and stuttered,""It…broke again!"
"What about now?"
"Eh? It can be used again!"
"What about now?"
"I can't enter again!"
"What about now?"
"Uh, the internet is back online."
This time, even the slowest person noticed that something was wrong.
"Su Dong, how did you do it?" Officer Yang asked excitedly.!”
"It's very simple. I'll unplug the hotel's internet.”Su Dong said casually.
“………”
Everyone was stunned.
When you said you were going out, you meant you were going to the hotel's internet?!
"Wait a minute, I understand what you mean.”Officer Yang was the first to understand and immediately rushed out of the door.
The group of people behind him also understood and immediately followed.
Beside the electric box, Su Dong was leisurely eating some fruits that he had picked up from a restaurant.
It was a very interesting case. He didn't know if this hacker was good at hacking, but he was pretty good at psychology.
Everyone was fooled by the hacker. With the hacker's initiative to expose it, everyone thought that the hacker had implanted a trojan virus in the computer and used it to control the hotel's network.
But in fact, the hackers did not plant any viruses in the hotel's computers. The network security of a hotel of this level was quite good, and most hackers could not hack into the system.
Therefore, the IT manager, many computer experts, and even the vice dean of the School of Computer Science at Shuzhong University failed to discover the problem.
This was because this problem did not exist at all. There was no trojan horse virus to begin with.
But if there was nothing wrong with the computer, what was the problem?
Answer:
Everyone's attention had been diverted to the computer by the hacker, so no one noticed the small mistake of the internet connection.
After all, if this was a hacker's network attack, who would have thought that there would be a problem with the internet? Hackers could only operate on the Internet, but they could not travel across space to the engineering department to pull out the network.
In fact, Su Dong discovered this problem by accident.
Because he realized that the timing of the hotel's internet blackout was too coincidental. It was all in the afternoon, and it was between two o'clock and twelve o'clock in the morning. Moreover, the internet was cut off every two hours, and the time of the blackout was one hour.
Coincidentally, the hotel security guards went to work at noon and got off work at midnight.
Coincidentally, the security guards could enter the hotel's engineering department's power system at any time because they had to check the safety issues.
Coincidentally, the security guards changed shifts every hour. If they wanted to, the security guards could enter the power system at the beginning of the inspection and unplug the internet. They could then connect the internet before the inspection ended.
Therefore, there was no such thing as high technology and hacking skills. Many complicated criminal cases were actually so simple and low-level when solved?
Of course, before that, Su Dong had specially returned to the surveillance room and asked Number 49 to check the surveillance cameras of the engineering department during the dozens of blackouts in the past three days. After confirming that it was really the same security guard, he dialed the internet.
No one would have thought that the mysterious and omnipotent hacking skills were actually the security guards pulling out the internet cable every two hours.
There was a saying that went," High-end ingredients often only require the simplest cooking method.”
