Let you go fishing, you caught the nuke?

“How’s it going, do you have any ideas?” Officer Yang looked at him.

Su Dong nodded, then shook his head again, “A little idea, but need to be verified.” ”

“Are you sure there’s nothing wrong with the hotel system?”

The university professor snorted softly, “I guarantee with my credibility that there are no backdoors and viruses left by hackers in the computer.” ”

That’s it.

Su Dong nodded his head in understanding, and then walked out the door again, “I’ll go out, you wait.” ”

“By the way, give me a walkie-talkie for a moment to get in touch.”

Crowd: “??? ”

Officer Li frowned, “Old Yang, is this foreign aid you are calling reliable?” ”

Officer Yang looked relaxed, “Try it, anyway, now you don’t have any ideas, and it won’t take long.” ”

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

But at this time, the IT manager in front of the computer desk changed his face, “No, the network is broken again!” ”

Professor Li Officer University immediately walked forward to look at the computer homepage, “Broken again?!” Didn’t it end half an hour ago?! How did it break again?! ”

“Impossible, obviously there is no backdoor, there is no virus software, how can it be broken?!”

Everyone was puzzled.

But at this time, Su Dong’s voice came from the intercom, “Hey, hey, I’m Su Dong, how is the hotel network now?” Is it broken again? ”

Officer Yang frowned, “Yes, it is broken again, I don’t know what’s going on, I used to stop every two hours, this time it was actually early, only half an hour to stop.” ”

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

“Now?” Officer Yang Yimeng, “Didn’t you tell me?” The network is down. ”

“Restored!” The IT manager looked at the computer and excitedly said, “The Internet can come in again.” ”

Officer Yang: “??? ”

Officer Lee: “??? ”

University Professor: “??? ”

What’s the situation? It only took less than a minute to break and then recover?!

“Now?” In the intercom, the sound of Su Dong came again.

The IT manager failed to refresh the network, stammering, “Again… Broken again! ”

“Now?”

“Huh? It can be used again! ”

“Now?”

“I can’t go in again!”

“Now?”

“Oh, the network is good again.”

At this point, even the most obtuse people noticed that something was wrong.

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

“Quite simply, I pulled out the hotel’s broadband.” Su Dong said lightly.

“………”

All were blindfolded.

You say go out, is to pull the hotel’s broadband?!

“Wait a minute, I see what you mean.” Officer Yang took the lead in understanding and immediately grabbed the door and came out.

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

Next to the electrical box, Su Dong was leisurely eating fruit, which was taken by hand from a passing restaurant.

Very interesting case, this hacking technology is not good or not, but psychology is very good.

Everyone was fooled by hackers, and under the active exposure of hackers, everyone preconceived that the hackers had implanted a Trojan virus in the computer to control the hotel’s network.

But in fact, hackers have not implanted any viruses in hotel computers, and the network security of hotels at the level of Hilton is still very good, and most hackers cannot break into the system.

So IT managers, many computer experts, and even the deputy dean of the School of Computer Science at Yushu Central University failed to find problems.

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?

A: Broadband!

Everyone’s attention was diverted to the computer by hackers, and no one paid attention to such a small oversight as broadband.

After all, if this is a hacker’s cyberattack, who would have thought that broadband would go wrong? Hackers can only operate on the network, and they can’t cross the space to pull out the broadband of the engineering department.

In fact, Su Kinetic Energy found this problem as an accident.

Because he found that the time of the hotel’s disconnection was also too coincidental, it was in the afternoon, or it was after two o’clock to 12:00 a.m. this time period, and it was also disconnected every two hours, and the disconnection time was one hour.

It just so happened that the hotel security guard went to work at 12 o’clock in the morning and left at 12 o’clock in the morning.

It just so happens that the security guard can enter the power system of the hotel engineering department at any time because of the security check.

It just so happens that the security guard is an hour a change, if you want, the security guard can enter the power system at the beginning of the inspection to pull the broadband, and then connect the broadband before the end of the inspection.

So, there is not so much high-tech and hacking technology at all, a lot of complex criminal cases, when unraveled, it turns out to be so simple and so low?

Of course, before that, Su Dong also deliberately returned to the monitoring room, looking for No. 49 to check the monitoring of the location of the engineering department during the three days of more than a dozen power outages, and found that it was really the same security guard, before unplugging the broadband.

No one could have imagined that what you thought was a mysterious and omnipotent hacking technique was actually a security guard pulling the network every two hours.

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