Let You Go Fishing, You Caught A Nuke?

"How is it, do you have any ideas?" Officer Yang looked at him.

Su Dong nodded, then shook his head again, "I have an idea, but I need to verify it."

"Are you sure there is nothing wrong with the hotel system?"

The university professor snorted softly, "I use my credit to guarantee that there are no backdoors and viruses left by hackers in the computer."

That's it.

Su Dong nodded to understand, and then walked out the door again, "I'll go out for a while, you wait."

"By the way, give me a walkie-talkie, and it will be convenient to contact you later."

Everyone: "???"

Officer Li frowned, "Old Yang, is the foreign aid you called reliable?"

Officer Yang looked relaxed, "Try it, anyway, now you have no idea at all, and it won't take long."

After that, a group of people chatted and began to explore how the hackers did it.

But at this moment, the face of the IT manager in front of the computer desk changed, "No, the network is disconnected again!"

The professor of Li Police University immediately walked forward and looked at the computer homepage, "It broke again?! Didn't it just break half an hour ago?! Why did it break again?!"

"Impossible, there is no backdoor and no virus software, why is it broken?!"

Everyone was puzzled.

But at this moment, Su Dong's voice came from the walkie-talkie, "Hey, hey, I'm Su Dong, how is the hotel network now? Is it disconnected again?"

Officer Yang frowned, "Yes, it's broken again. I don't know what happened. It used to stop every two hours, but this time it was earlier than half an hour."

After a few seconds, Su Dong asked again, "How is it now?"

"Now?" Officer Yang was confused, "Didn't I tell you? The internet is down."

"Recovered!" The IT manager said excitedly, looking at the computer, "The Internet can be accessed again."

Officer Yang: "???"

Officer Li: "???"

University professor:"???"

what's the situation? It only took less than a minute to break, and it recovered? !

"What about now?" Su Dong's voice came from the walkie-talkie again.

The IT manager failed to refresh the network and stammered, "It's...broken again!"

"now what?"

"Huh? It can be used again!"

"now what?"

"Can't get in again!"

"now what?"

"Uh, the network is fine again."

This time, even the dullest person noticed something was wrong.

Officer Yang immediately asked excitedly, "Su Dong, how did you do it?!"

"It's very simple, I unplugged the hotel's broadband." Su Dong said lightly.

"..."

Everyone was blinded.

What do you mean by going out, is to unplug the hotel's broadband? !

"Wait a minute, I understand what you mean." Officer Yang was the first to understand and rushed out the door.

A group of people behind him also understood and immediately followed.

Next to the electric box, Su Dong was leisurely eating fruit, which he picked up from a passing restaurant.

Very interesting case, I don't know if this hacking technique is good or not, but I have learned psychology very well.

Everyone was fooled by the hackers. Under the active exposure of the hackers, everyone preconceived that the hackers had implanted a Trojan virus in the computer, and used this influence to control the hotel's network.

But in fact, the hacker did not implant any virus in the hotel computer. The network security of a hotel of Hilton's level is still very good, and most hackers cannot invade the system.

Therefore, IT managers, many computer experts, and even the deputy dean of the School of Computer Science at Shuzhong University failed to find the problem.

Because this problem does not exist at all, there is no Trojan virus.

But if there is no problem with the computer, what is the problem?

Answer: Broadband!

Everyone's attention was diverted to the computer by hackers, and no one paid attention to such a small omission of broadband.

After all, if it is a preconceived idea that this is a hacker's network attack, who would have thought that there would be problems with broadband? Hackers can only act on the network, and they can't pull broadband from the engineering department across the space.

In fact, it was an accident that Su Dong found out about this problem.

Because he found that the time when the hotel was disconnected from the Internet was too coincidental. It was all in the afternoon, and it was also between 2:00 and 12:00 in the morning, and it was still disconnected every two hours. One hour.

And it just so happened that the hotel security went to work at 12:00 noon and got off work at 12:00 in the morning.

It was just right that the security guard could enter the power system of the hotel engineering department at any time because he wanted to check the safety problem.

And just right, the security guards change every hour. If they want, the security guards can enter the power system to unplug the broadband at the beginning of the inspection, and then connect the broadband again before the inspection is over.

Therefore, there are not so many high-tech and hacking techniques at all, and many complex criminal cases, when solved, turned out to be so simple and so low?

Of course, before that, Su Dong also went back to the monitoring room on purpose, went to No. 49 to check the monitoring of the location of the engineering department during the period of more than ten power outages in the past three days, and found that it was the same security guard, and only then went to unplug the broadband. .

No one can imagine that what you think is a mysterious and omnipotent hacking technology, the reality is that the security is unplugging the network cable every two hours.

There is a saying that goes, "High-end ingredients often only require the simplest cooking methods."
