Yuchu Department Store is the most high-end shopping mall in City A, its monitoring system is very advanced, not only can 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 reenact what she once did in an American restaurant.

If you want to hack into the monitoring system of a shopping mall, you must first be close to its local area network, so Ye Tang chose this café on the first floor of Yuchu Department Store, which has both external WiFi and internal local area network.

The first step is to connect to the local area network.

Ye Tang took a sip of coffee and pursed his lips, a little bitter. She got up and walked to the service desk, took two small packets of candy, and glanced at the store manager who was making coffee, the store manager was wearing a uniform black shirt uniform, and a name tag pinned to the upper left pocket of the shirt - store manager: Li Jun.

Then she began to try to connect to the LAN, enter Li Jun's pinyin, brute-force crack the password, and don't have to be very violent, the password used at work is usually very simple, maybe the same as the WiFi password, maybe it's 123456, maybe it's 000000, maybe it's the person's birthday.

The brute-force cracking software only ran for two minutes, and it successfully entered the 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, so it is necessary to scan all the internal IPs and check 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 ten minutes to find this key IP.

The third step is to download the video directly in the host storage.

In fact, the host of the monitoring system also has an account password, but the staff responsible for monitoring work generally do not have a high sense of security and will not change the default account name and default password. Sure enough, the account name of this host is admin, and the password is 88888, Ye Tang simply hacked into the background without much effort, and the means used were not very sophisticated hacking techniques.

The video file is very large, the network speed is limited, and it will not be able to download it for a while.

Ye Tang looked at the time, it was still early, not in a hurry, she ordered another cup of coffee, took out her mobile phone, lowered her head and put the phone card she had just done in, the morning sun sprinkled on her from the window, softening her face, and the broken hair on her forehead became more distinct.

At this time, there were very few customers in the café, and the manager and waiter cast their eyes at this girl more than once, because she was very beautiful, and her appearance was the type that would be liked at first sight, with beautiful eyebrows and eyes, clean and gentle, harmless to humans and animals. Her coffee-drinking posture was the most beautiful of the guests they had ever seen, not deliberate at all, and she could be seen inadvertently.

Is she a college student?

They wondered what she was doing with her laptop. Looking at study materials? Reading a novel? Watch the video?

The second cup of coffee bottomed out, Ye Tang cut off the network, closed the notebook, put the computer in the box, got up to leave, and 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 watched her walk away.

Ye Tang returned home unhurriedly, Zhao Zhenfang had already gotten home from work first, the old man didn't know the news of his expulsion, she had just made lunch, and when she heard the sound of the door closing, she poked her head out of the kitchen and asked Ye Tang, "Where have you been again?" ”

"I went out for a casual stroll," Ye Tang said as he changed his shoes.

"You, you're wandering around on sick leave, who said you have to study hard? Next week, the exam will be adjusted in September, you don't read, just wander outside, you brag and brag! Zhao Zhenfang was average, and felt sorry for her granddaughter, "Hungry, right?" Come and eat. ”

Zhao Zhenfang's dishes are very suitable for Ye Tang's taste, it is light, today she made fried beef with leek eggs and green peppers, Ye Tang drank too much coffee, and she couldn't eat it a little, so she only ate a small half bowl of rice.

Zhao Zhenfang was unhappy, she hoped that the child would eat more, "Look how thin you are, eat more!" As she spoke, she put a few pieces of beef into Ye Tang's bowl.

Looking at her kind and caring smile, Ye Tang couldn't say the word "expelled", and she was even more angry with Su Xiaodong's family in her heart.

In any case, she still had to tell the old man the truth. She put Zhao Zhenfang's old man's mobile phone on the coffee table at dinner, and said very seriously, "I received a call from your leader in the morning, and he said that you don't have to go to work tomorrow." ”

The smile on Zhao Zhenfang's face suddenly froze, and she put the chopsticks on the side of the bowl, very silent. Ye Tang clearly saw the bitterness and sadness in her eyes like being manipulated by fate, as well as a trace of tears in the corners of her eyes. But the old man quickly laughed, "You urged me to resign, now it's okay, I don't have to do it, lest I go to the leader to mention this stubble, and I'm embarrassed." ”

Ye Tang pursed his lips tightly and did not speak.

Since God asked her to live instead of Xiao Yetang, her only belief and mission is to make Zhao Zhenfang happy in the future.

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, so many videos, it is impossible to watch them in a short time.

Each video also has a separate text file, which indicates the specific floor and counter number of Yuchu Department Store, if it is a shopping mall elevator or a warehouse surveillance, the label is different, Ye Tang only needs to filter out the video on the 6th floor where the UYX counter is located.

However, she didn't know what the number of the monitoring probe near the counter was, so she had to watch the videos one by one, gradually narrowing down the scope, and the amount of task was not small.

Soon she found out the picture when she bought the computer, put on the headphones on the phone, turned up the volume, she could clearly hear the conversation between her and the shopping guide, in the video she pointed to the XXX0 model notebook and said that she wanted to buy this model. The shopping guide also mentioned the discount of 5000 off for 5000.

And the conversation between the supervisor and the shopping guide discussing how to pit her was completely recorded by the monitoring probe in the other direction, they thought that she couldn't hear it if she was far away, but she happened to be standing under a surveillance camera!

Finding the decisive evidence, Ye Tang didn't stop there, she continued to study the video she downloaded from the mall and found something very interesting.
