Yuchu Department Store is the highest-end shopping mall in City A. Its surveillance system is very advanced. It can not only record but also record. Each camera has a small microphone next to it.
Ye Tang thinks that the camera must have captured something!
She intends to repeat what she did in American restaurants.
To hack into the surveillance system of a shopping mall, you must first be close to its local area network, so Ye Tang chose this coffee shop located on the first floor of Yuchu Department Store. It has both external WiFi and internal LAN.
The first step is to access the LAN.
Ye Tang took a sip of coffee and pursed her mouth, a bit bitter. She got up and walked to the service desk, took two small packets of sugar, and glanced at the shop manager who was making coffee. The shop manager was wearing a uniform black shirt uniform with a name tag in the upper left pocket of the shirt—the shop manager: Li Jun.
Next, she tried to connect to the LAN, typed in Li Jun’s pinyin, and cracked the password by brute force. The password used at work was usually very simple, maybe the same as the WiFi password, maybe 123456, maybe 000000, maybe This person's birthday.
The brute-force cracking software only ran for two minutes, and successfully entered the shopping mall’s LAN as Li Jun.
The second step is to find the IP address of the monitoring host.
In such a large shopping mall, the IP address of the monitoring host is usually separated from other IPs. In this way, all internal IPs must be scanned to find out the IP of the monitoring host. This step requires a little patience and time. The data traffic of the mall is too large, and it took Ye Tang 20 minutes to find this key IP.
The third step is to directly download the video in the host storage.
The monitoring system host actually has an account and password, but the staff responsible for the monitoring work generally do not have high security awareness and will not modify the default account name and default password. Sure enough, the account name of this host was admin, and the password was 88888. Ye Tang simply hacked into the background without any effort, and the methods used were not so sophisticated hacking techniques.
The video file is very large, the internet speed is limited, and the download can't be finished for a while.
Ye Tang checked the time, it was early, and she was not in a hurry. She ordered another cup of coffee, took out her mobile phone, and lowered her head to put in the calling card she had just made. The morning sun shone on her from the window, softening her face. The broken hair on her forehead also became more distinct.
At this time, there are very few customers in the cafe. The shop manager and waiter cast their eyes on the girl more than once, because she is beautiful, and her looks are the type that will be liked at first sight, beautiful and clean. Gentle, harmless to humans and animals. Her coffee-drinking gesture is the best among the guests they have ever seen. She is not deliberate at all, and she can be seen inadvertently.
Is she a college student
They are curious what she is doing with the notebook? See learning materials? Reading novels? Watch the video
The second cup of coffee bottomed out. Ye Tang cut off the internet, closed the notebook, put the computer in the box, got up and left. When she passed the service desk, she smiled and said to the store manager, "Thank you."
The store manager was stunned by her smile and stared blankly at her as she walked away.
Ye Tang returned home unhurriedly. Zhao Zhenfang had already gotten home from get off work. The old man did not know the news of her being fired. She had just made lunch and heard the closing of the door. She poked her head out of the kitchen and asked Ye Tang, " Where did you go again?"
"Go out and just stroll around," Ye Tang said while changing his shoes.
"You, take advantage of the sick leave to hang around, who said to study hard? The exam will be scheduled next week in September. You don't read books, just go shopping outside, you brag!" Zhao Zhenfang was so silly that she felt sorry for her granddaughter. "Are you hungry? Come and eat."
Zhao Zhenfang’s dishes were very light to Yetang’s taste. Today, she made stir-fried beef with chives, eggs and green peppers. Yetang drank too much coffee and couldn’t eat, so she ate only a small bowl of rice.
Zhao Zhenfang was not happy anymore. She hoped that the child would eat more, "Look how thin you are, eat more!" As she said, she put a few pieces of beef into Yetang's bowl.
Seeing her kindly and caring smile, Ye Tang couldn't say the word "expelled", and her anger towards Su Xiaodong's family became even greater in her heart.
In any case, she still has to tell the old man the facts. She put Zhao Zhenfang's old man's cell phone on the dining table and said seriously, "I received a call from your leader in the morning. He said that you don't need to go to work tomorrow."
The smile on Zhao Zhenfang's face suddenly froze, she put the chopsticks on the side of the bowl, very silent. Ye Tang clearly saw the bitterness and sorrow of being manipulated by fate in her eyes, as well as the tears in the corner of her eyes. But the old man laughed quickly, "You urge me to resign. This is all right, I don't have to do it anymore, lest I go to raise this issue with the leader, I'm not embarrassed."
Ye Tang pressed her lips tightly and didn't speak.
Since God asked her to live on behalf of Xiao Yetang, her only belief and mission is to make Zhao Zhenfang happy in the days to come.
Entering the bedroom, Ye Tang turned on the computer and found one of the files, which contained a huge compressed package. After decompression, tens of thousands of minutes of video data appeared on the computer screen. It is impossible to watch so many videos in a short time. .
There is also a separate text file for each video. The file indicates the specific floor and counter number of Yuchu Department Store. If it is a store elevator or warehouse monitoring, the label is different. Ye Tang only needs to filter out the UYX counter. Video on the 6th floor.
However, she didn't know the number of the surveillance probes near the counter, so she had to watch the video one by one, gradually narrowing the scope, and the task load was not small.
Soon she found out the screen when she bought the computer, put on the earphone of the mobile phone and turned up the volume, she could clearly hear the conversation between her and the shopping guide. In the video, she pointed to the XXX0 laptop and said that she wanted to buy this model. The shopping guide also mentioned the discount of 500 minus over 5000.
The conversation between the supervisor and the shopping guide about how to pit her was completely recorded by a surveillance probe in the other direction. They thought they were a little farther away from her and she couldn't hear it, but they happened to be standing under a surveillance camera!
After finding decisive evidence, Ye Tang did not stop there. She continued to study the video she downloaded from the mall and found some interesting things.
