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 from Grand Hyatt Hotel, and is quite familiar with Sun Ancheng. He said: "Old Sun, just a few minutes before you came, all the surveillance equipment in the hotel were infected with the virus, and the surveillance system was paralyzed and continued.
It took three or four minutes to get back to normal, and now it can work normally, but... all the video materials today are lost."
The Grand Hyatt Hotel's monitoring system will automatically download the video data of the previous day to the hard drive at 3 a.m. every day, and it was saved in the cloud before this.
Moreover, the hard disk capacity is limited, and only 30 days of recording will be retained at most. After more than 30 days, the video of the earliest one will be automatically rejected.
By analogy, the video data on the hard drive is always maintained at thirty days.
All the things that happened at the hotel gate today were recorded by the surveillance equipment.
Sun Ancheng came here to get the video information at the entrance of the hotel today, but before the video information could be downloaded to the hard drive, all of it was lost due to poisoning!
"How could it be such a coincidence?" Sun Ancheng murmured with frown.
This is indeed abnormal. The monitoring system of Grand Hyatt Hotel does not necessarily fail once in 800 years. This time, when some unexpected situations occurred, they were infected with the virus.
How could such a coincidence be?
Qin Hai said: "Our external network security officer is checking. Let's see if you find anything later."
He was also a little confused about this situation.
"Yes." Sun Ancheng nodded with a gloomy face.
The two of them waited at the door of the monitoring room.
A few minutes later, a gentle young man wearing black-framed glasses, carrying a backpack and looking gentle, lowered his head, as if he was talking to himself, walked out of the monitoring room.
"How about Xiaodong, have you noticed anything?" Qin Hai asked hurriedly.
The young man who asked Xiaodong to look up at Qin Hai, stunned, as if he was thinking about something that had been interrupted, and 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 surveillance system this time is called 'Slotch', which is not a rare virus, and I don't have it.
The traces of human operation were found, and it was because the system was not properly operated and got infected. Oh, I just filled out several loopholes in the firewall."
“…”
Sun Ancheng and Qin Hai looked at each other and were silent.
Strictly speaking, Xiaodong is not an employee of their hotel. He is just working in an Internet company next to him and is responsible for the network security work of Grand Hyatt Hotel. Although he is young, he is very capable and is very good at communication and network security.
.
Therefore, Sun Ancheng and Qin Hai could not find any reason to doubt Xiaodong's conclusion.
"Since that's the case, thank you Xiaodong. The money will be on your card afterwards." Qin Hai smiled.
"Okay, I'll go back to work first."
Xiaodong smiled shyly, pushed down the glasses on his nose, and walked away.
This is how he cooperated with Grand Hyatt Hotel. He did something and received some money. Grand Hyatt Hotel was rich and never disappointed him. Even the money for this kind of thing can often be
It's a month's salary.
"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 there. He said there is no trace of human operation, so there should be no mistakes. It seems that it is really a coincidence."
Sun Ancheng nodded slowly.
But his brows still did not relax.
I always feel something is wrong in my heart.
On 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 "Magic Shadow" in the address book, clicked on the dialog box, and sent a message.
"Have you made a move recently?"
Not long after.
The Demon Shadow has recovered a "Yeah"!
Xiaodong narrowed his eyes and realized in his heart.
...
timeet is a niche social software. Its purpose is to "provide an open social platform for high-end and sophisticated cybersecurity talents around the world." In other words, this software is used by hackers to communicate, and it must be invited by old users.
Only by downloading the software and registering an account can you greatly ensure the purity of timeet users and basically not be involved in by people outside the industry.
However, after all, hackers are not professions that can be brought to the table, and often they will touch the boundaries of the law. Therefore, on timeet, almost no one uses the real name, but will each take a unique code name, and they will share the same code with each other.
Communication is also called by code names. Few people will know the other party’s real name, and even the IP address is encrypted by themselves.
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.
Xiao Dongming is a senior programmer in an IT company of a small size. He is secretly a well-known hacker. The Magic Shadow he contacted on timeet is naturally a hacker.
Just now, Xiaodong felt a sense of familiarity when he was checking the virus in the surveillance system of Grand Hyatt Hotel.
Whether it is the virus itself, the method of breaking through the firewall, etc., it seems to have a tag, and this tag slowly coincides with the magic shadow in Xiaodong's mind.
So Xiaodong guessed whether the Magic Shadow took action.
Although the hacking community does not clearly define their respective territory, generally speaking, as long as there are no grudges, few hackers will fight each other.
Take this incident as an example. Magic Shadow did not infringe on the surveillance system of Grand Hyatt Hotel. If someone from the thief comes forward to help Grand Hyatt Hotel, it is equivalent to directly treating the Devil.
Shadow declares war and will stand opposite to the Demon Shadow, and the two of them are enemies!
In other words, if there is a firewall that Xiaodong personally set up in the monitoring system of the Grand Hyatt Hotel, then Moying will not invade the Grand Hyatt Hotel's system at will without any special reason, otherwise it will be
It is regarded as a provocation to Xiaodong.
It is precisely because of this reason that after Xiaodong realized that it might be the Magic Shadow, he did not do more. He just checked it briefly and repaired the hotel firewall with a general method.
Doing this will not match the Magic Shadow, and it will not be considered a waste of money from Grand Hyatt Hotel.
The demon shadow asked again: "How did you know, weird fox?"
The weird fox is Xiaodong's code name on timeet. In the hacking world, it is also a little famous, and it belongs to the same level as the magic shadow.
Xiaodong (通小小) replied: "I recognize your technique."
Magic Shadow: "But I didn't see your mark."
When hackers build firewalls, they usually leave their own unique marks as symbols of their identity. If a hacker sees this mark, they may give up taking action.
The Demon Shadow can't say that he is afraid of the weird fox, but if it is not necessary, he really doesn't want to have such an enemy. Moreover, the two of them are in the same circle, and they actually get along well.
So he explained.
Xiaodong (骨小): "Don't worry, that firewall was not arranged by me. I just worked part-time to deal with some simple problems."
Magic Shadow: "I just said, if it were you who defended, how could I break through so easily?"
Xiaodong (Strange Fox): "…"
Sun Ancheng did not get the surveillance video. Although he was still confused, he did not pay much attention to it.
It was 4 pm that day.
