The first thousand four hundred and forty-six chapters ghost
"What did you say!?" Sun Ancheng stared at Qin Hai, the head of the security department, in disbelief.
Qin Hai is also an old man at the Grand Hyatt Hotel and is relatively familiar with Sun Ancheng. He said: "Old Sun, just a few minutes before you came over, all the monitoring equipment in the hotel were infected with the virus, and the monitoring system was paralyzed. This continued
It took three or four minutes to return to normal, and now it can work normally, but... all the video data today has been lost."
The surveillance system of the Grand Hyatt Hotel will automatically download the previous day's video data to the hard drive at three o'clock in the morning every day. Before that, it was saved in the cloud.
Moreover, the capacity of the hard disk is limited, and only thirty days of recordings will be retained at most. After thirty days, the earliest recordings of the day will be automatically discarded.
By analogy, the video data in the hard disk is always maintained for thirty days.
What happened at the hotel gate today was all recorded by the surveillance equipment.
Sun Ancheng came here just to get the video data at the hotel entrance today, but before the video data could be downloaded to the hard drive, it was all lost due to poisoning!
"How could it be such a coincidence?" Sun Ancheng muttered with a frown.
This thing is indeed abnormal. The surveillance system of the Grand Hyatt Hotel has rarely failed once in eight hundred years, but this time, it happened to be infected by a virus when some unexpected circumstances occurred.
How could such a coincidence happen?
Qin Hai said: "Our external network security officer is checking, let's wait and see what we find."
He was also a little confused about this situation.
"Yeah." Sun Ancheng nodded gloomily.
The two of them waited at the door of the monitoring room.
A few minutes later, a young man with black-rimmed glasses and a backpack walked out of the monitoring room with his head lowered and seemingly muttering to himself.
"How are you, Xiaodong? Did you find anything?" Qin Hai asked quickly.
The young man named Xiaodong raised his head and looked at Qin Hai. He was startled. It seemed that he was thinking about something and was interrupted. He didn't react for a while.
"Xiaodong?"
Qin Hai shouted softly again.
Xiaodong came back to his senses, blinked, looked at Qin Hai and said: "The virus in the hotel monitoring system this time is called 'Sloth'. It is a not uncommon virus, and I don't have it."
I found traces of human operation. It should be that the system was infected by the virus due to improper operation. Oh, I just filled in a few firewall loopholes."
"..."
Sun Ancheng and Qin Hai looked at each other and fell silent.
Strictly speaking, Xiaodong is not an employee of their hotel. He just works at a nearby Internet company and is responsible for the network security work of the Grand Hyatt Hotel part-time. Although he is young, he is very capable and is very good in communications and network security.
.
Therefore, neither Sun Ancheng nor Qin Hai could find any reason to doubt Xiaodong's conclusion.
"In that case, thank you very much, Xiaodong. The money will be transferred to your card later." Qin Hai smiled.
"It's easy. I'll go back to work first."
Xiaodong smiled shyly, pushed up the glasses on the bridge of his nose, and walked away.
His cooperation with the Grand Hyatt Hotel was like this. He would get a lot of money for doing something, and the Grand Hyatt Hotel had a lot of money and would never let him down. In many cases, even the money he could get from this thing would be enough.
It’s equivalent to one month’s salary of his.
"Old Qin, what do you think?" After Xiaodong left, Sun Ancheng withdrew his gaze and looked at Qin Hai and asked.
Qin Hai rubbed his hands and said: "Xiaodong's level is still good. He said there are no traces of human manipulation, so there should be no mistakes. It seems that it is just a coincidence."
Sun Ancheng nodded slowly.
But his brows still didn't relax.
I always have a vague feeling in my heart that something is wrong.
the other side.
After Xiaodong walked out of the hotel, he took out his mobile phone and logged into a software called "timeet". Then he found a person named "Moying" in the address book, clicked on the dialog box, and sent a message.
"Have you taken action recently?"
It didn't take long.
The demonic shadow recovered a "hmm"!
Xiaodong narrowed his eyes and understood.
…
Timeet is a niche social software. Its purpose is to "provide an open social platform for top network security talents around the world." In other words, this software is used by hackers to communicate, and it must be invited by old users.
Only then can you download the software and register an account, which to a large extent ensures the purity of timeet users and basically prevents outsiders from getting in.
However, after all, hacking is not a profession that can be put on the table, and it often touches the boundaries of the law. Therefore, on Timeet, almost no one uses their real name. Instead, they each use a unique code name.
Communication is also done by code names. Very few people know the other party’s real name. Even the IP address is encrypted by oneself.
Hackers on timeet often have some "discussions" and even hold some "official activities". Some people defend and some attack. Gradually, many people become familiar with each other's habits and techniques.
On the surface, Xiaodong is a senior programmer at a small IT company, but secretly he is also a well-known hacker. The Moying he contacted on Timeet is naturally a hacker as well.
Just now, when Xiaodong was checking the virus in the surveillance system of the Grand Hyatt Hotel, he felt a vague sense of familiarity.
Whether it's the virus itself, or the method of breaking through the firewall, etc., it all seems to have a label, and this label slowly overlaps with the demonic shadow in Xiaodong's mind.
So Xiaodong guessed whether it was Mo Ying who took action.
Although the hacker community does not clearly define their respective territories, generally speaking, as long as there are no grudges, few hackers will go against each other.
Take this incident as an example. Moying's attack on the surveillance system of the Grand Hyatt Hotel did not infringe on anyone in the hacker community. If someone from the hacker community came forward to help the Grand Hyatt Hotel, it would be equivalent to directly attacking the Moying community.
If Shadow declares war, he will stand on the opposite side of Demon Shadow, and the two of them will be enemies!
In another situation, if there is a firewall installed by Xiaodong himself in the monitoring system of Grand Hyatt Hotel, then the demon shadow will not invade the system of Grand Hyatt Hotel at will without any special reason, otherwise it will also be
Seen as a provocation to Xiaodong.
It is for this reason that after Xiaodong realized that it might be Mo Ying, he didn't do anything more. He simply checked and repaired the hotel firewall using common methods.
By doing this, you won't have to fight against the demonic shadow, and at the same time, you won't get the Grand Hyatt Hotel's money in vain.
Moying asked again: "Juihu, how did you know?"
Weihu is Xiaodong's codename on Timeet. He is somewhat famous in the hacker world and is on the same level as Moying.
Xiaodong (Sly Fox) replied: "I recognize your technique."
Phantom: "But I didn't see your mark."
When hackers build a firewall, they usually leave their own unique mark as a symbol of identity. If a hacker sees this mark, they may give up.
It can't be said that Moying is afraid of the fox, but he really doesn't want to have such an enemy if it's not necessary, and the two of them are in the same circle, and they actually get along pretty well.
So he explained.
Xiaodong (Guihu): "Don't worry, I didn't set up the firewall. I'm just dealing with some simple problems part-time."
Demon Shadow: "Let me tell you, if you were defending, how could I break through so easily?"
Xiaodong (Sly Fox): "..."
Sun Ancheng did not get the surveillance video. Although he still had doubts in his heart, he did not pay too much attention to it.
At 4 p.m. that day.
