Chapter 15 Done!
Where does one let down most of their guard?
is home.
For the city guards, it is the City Guard Bureau. They were already very tired from arresting people from the lower city. If it hadn't been for the rain, they would probably still be wandering through the streets and alleys outside.
So everyone cherishes this rare rest time, because everyone knows that when the rain stops and the sun comes tomorrow, they will start the shuttle journey again.
Every time they thought of this, they couldn't help but curse those damn people from the lower city.
The lighting in the corridor was not soft, and the doors to the rooms on both sides were either closed or ajar, and snoring could be heard vaguely coming from behind the doors.
This is a good thing for Zhang Cishun and Jing Shuo.
However, the two of them kept their footsteps as low as possible.
Jing Shuo held the knife in his hand, his body tensed, and his eyes moved away from the half-opened doors one by one.
Tensions are inevitable
but nothing unexpected happens.
Through the information mapping function of the watch, Zhang Cishun could 'see' that there was no 'person' in the computer room. The city guards in other rest rooms made no move to get up.
He moved his gaze away from the watch and placed it on the door control of the computer room.
Just as he thought, even though the city was rebuilt after the apocalypse, people's defense level for the computer room was still not low.
But probably the biggest mistake they made was using electronic access control.
Zhang Cishun reached out to touch the display, quickly read through the lighted screen, and then started writing.
Typically, the logic of an access control system is based on a series of control and verification steps to ensure that only authorized personnel have access to a specific area.
The access control system will identify by swiping a card, scanning a fingerprint, entering a password, or using biometric identification. And this is the first process when the access control starts working.
Zhang Cishun does not need to provide identification cards or fingerprints. He only needs to force access event records of the access control system and intercept data from the records to match the current identification process.
According to the mechanical program operation method of the access control system, as long as the visitor successfully compares with the access rights pre-stored by the access control system, the door lock will naturally be opened.
It seems simple, right, but it's not.
When Zhang Cishun calls up the access event record, he must be careful not to trigger the abnormality detection of the access control. After all, his operation is, in the final analysis, illegal intrusion. But the procedure is mechanical, but Zhang Cishun can flexibly change it at any time as needed.
No program system dares to claim that it is without loopholes.
A white data interface popped up with Zhang Cishun's operation. This was a past visit record. After Zhang Cishun simply scanned it, he retrieved the one he needed.
Then he hacked into the system.
"def _authenticate_user(self, username, password):
if_username in self . authorized_users and self . authorized_users[username]==pasaword:
return True
else:
return False
..."
User authentication is basically a must in all access control systems, The code is pretty much the same, except in a fully iterative language. But obviously the computer language of this world has not departed from Zhang Cishun's cognition.
After inserting the information fragments in the access record into the system, the verification is completed instantly.
The scrolling code cascades down until finally a few lines of code appear.
"def open_door(self):
print("The door is open")
..."
"You are conducting an illegal intrusion... Gain data intrusion experience: 10."
"You are conducting an illegal intrusion... Gain data intrusion experience :10."
Several messages popped up on the system panel, but there were not many experience points.
Now is not the time to pay attention to this. After obtaining the authority to open the door, Zhang Cishun pushed the door open and entered.
The lights in the computer room were not turned on, so when Jing Shuo followed in and closed the door, the light that shone through the crack in the door disappeared.
Only the indicator lights on the machines arranged in the cabinet kept flashing.
Neither man was carrying portable lighting, but that wasn't a big deal.
After bringing up a white-background application interface on his watch, Zhang Cishun turned the display brightness to full. With the dense white light on his watch, he could already see the equipment in the computer room clearly.
There are three cabinets in the computer room, and each cabinet contains several layers of machines. The buzzing and clicking sounds are constantly telling Zhang Cishun one thing - they have been working for a long time. .
At this time, Zhang Cishun was no longer as cautious as he was in the corridor. He quickly walked to the cabinet and searched among various switches and servers.
He stopped in the middle of the third cabinet.
Through the display light of the watch, he could see the appearance of the device in front of him. It was a closed square box with some kind of logo-like icon on the side facing Zhang Cishun. There is a device on the right side of the chassis that looks like a computer optical drive in memory. There is also an enable button.
Zhang Cishun did not press it directly, but reached out to touch it and looked at the information display about it in the system. After confirming that it was what he was looking for, he pressed the button.
The clicking sound of the transmission is short and weak.
Immediately afterwards, there was the sound of the fan blades rotating in the chassis.
The logo icon facing him suddenly disappeared after flashing twice, and then a string of text appeared: Welcome to the central equipment management system.
The optical drive-like device on the right side began to slide out with a click of the lock, and a fully touch display screen was popped out.
The screen lights up after a few seconds
.
It is a login interface.
...
Jing Shuo did not enter the computer room, but leaned against the wall next to the door. His eyes were looking at Zhang Cishun who was operating quickly in the light, but his ears were sensitive to all the sounds outside the computer room.
It is not difficult to log in the information of two people in the current household registration information, but Zhang Cishun must note that the household registration information of the original owner of the watch still exists in the system. He needs to follow the original records of 'Zuoling' and 'Jingshuo' Household registration information is used to decide whether to completely overwrite or rewrite.
There is no problem with Jing Shuo's information. He overwrites the photo of Diao Zai (Jing Shuo's former name) that he had prepared long ago, and then changes some unreasonable information and puts it back in place.
But I am afraid that the 'Zuoling' I am currently using cannot be directly rewritten in the original owner's information.
There is a relationship between Zuo Ling and Zuo Yan.
If he only changes Zuo Ling but not Zuo Yan, problems will inevitably arise when someone inquires about it in the future. But if they change it together, the problem will be even greater.
You must know that Zuo Yan is currently wanted online.
What, are we going to change the wanted order as well?
This is obviously impossible.
Therefore, Zhang Cishun directly created a parallel document and copied a large number of identity information from other household registrations to create a forged copy for himself.
As for the name, Zhang Cishun did not write down his real name, but still used Zuo Ling.
The reason why he did this was because he had no way to rewrite the identity information on the watch, which was locked.
As for whether there will be trouble if he continues to use Zuo Ling's identity, Zhang Cishun cannot deny that there may be, but the problem will not be big, because there are a total of eighteen people named Zuo Ling in the entire database.
"Done?"
Jing Shuo asked when he saw Zhang Cishun pushing the screen back.
"Well, it's done, get ready to evacuate."
