In the Shuangqing City power grid system, the worm virus was wiped out by Shi Lei twice, but it appeared tenaciously twice.
Shi Lei couldn't understand this situation at first because Yi Zuer had clearly completely investigated and killed the internal network of the power grid system, especially during the second investigation, relevant personnel from the General Administration of Cybersecurity and the Cybersecurity Intelligence Department conducted special investigations and killing worms.
How could a worm virus come back if it is thoroughly investigated and killed?
Ling Yuguo reminded Shi Lei that the worm virus is not hidden in the network cable, and the network cable cannot store the worm virus. The worm virus is hidden at the other end of the network cable - the switch!
That's right!
The worm virus is hidden in the switch!
The power grid system in Shuangqing City is indeed separated from the Internet environment. Shi Lei also handles all corners of the power grid system, but Shi Lei did not remember the springboard between the power grid system and the Internet and the security of the switch.
"Damn it!" Shi Lei cursed in a low voice. Hiding the worm virus in the switch is not a superb technology. It is even a common practice. Shi Lei just ignored it for a while.
"Hmm?" Ling Yuguo heard Shi Lei's low curse and asked, "Boy Shi Lei, have you discovered what happened?"
"Well! Uncle Ling, the worm virus is hidden in the switch, I'll solve it immediately!" Shi Lei told Ling Yuguo his speculation.
Then, Shi Lei entered the switch on the internal network of the power grid system and inquired about the switch's simple file storage system. Sure enough, it was not beyond Shi Lei's expectations. Shi Lei discovered a worm virus in the switch.
Shi Lei and Yi Zuer once again analyzed the general characteristic code of worm viruses, and conducted investigation and killing work on the worm viruses in the switch through the special killing tool written by Shi Lei.
The worms that killed the switch were going very quickly. This time, Shi Lei encountered no trouble, but Shi Lei didn't know that another trouble was approaching.
A few minutes later, all switches connected to the power grid system were investigated and killed. Shi Lei established a solid defense strategy for the switch to prevent the switch from being infected with worm virus again.
After dealing with the security of the switch, Shi Lei returned to the power grid system. He lost the source of worm virus infection. This time, Shi Lei only needs to detect and kill the worm virus in the power grid system again, and the power grid system can truly restore normality.
However, the estimated situation is always beautiful, and the actual situation is always ever-changing.
When Shi Lei was preparing to investigate and kill the worm virus in the power grid system, he discovered a helpless fact, that is, the general feature code of the worm virus disappeared.
Hundreds of thousands of worm viruses permeate the power grid system of Shuangqing City, constantly mutating and self-replicating. If you want to find worm viruses one by one and delete them manually, it is almost impossible to complete the work.
Unless you find the common feature code again. or mutation rules!
"Shi Lei, have you found a common feature code?" Ling Yuguo asked Shi Lei. The previous two clearances and detection of worms were so smooth that Ling Yuguo was full of hope for Shi Lei, or Ling Yuguo had too high hopes for the two major security experts of Mirui Technology Group fabricated by Shi Lei.
As the saying goes, the greater the hope, the greater the disappointment.
Shi Lei gave Ling Yuguo an answer that disappointed him, "Uncle Ling, we are in trouble, and the general signature of the worm virus disappears. We suspect that the general signature of the worm virus two times before was just a trap deliberately arranged to delay our time layout. The worm virus that broke out this time is a complete worm virus and does not have a general signature. Unless mutation rules are found, it is difficult to delete all worm viruses at once."
Ling Yuguo frowned, "How long will it take to resolve this time?"
Shi Lei sighed, "Our experts said they don't know for the time being. It is difficult to analyze and discover the worm virus mutation rules and it will take more time."
"Okay! Try to deal with it. Our side and the Cybersecurity and Information Department will do their best." Ling Yuguo also sighed secretly. He knew that he could not place all hope on Shi Lei's side, and they also needed to work hard.
Shi Lei nodded, responded, and then hung up the phone.
"Yuzhuer, analyze the source code of the worm virus!" Shi Lei instructed that Yizhuer first parsed the source code of the worm virus through huge computing resources, and Shi Lei further analyzed the mutation rules.
Nearly an hour passed in a hurry, and it was 10 o'clock in the evening on February 13th. At this moment, it had been more than two hours since the power outage in Shuangqing City.
Shi Lei analyzed the source codes of more than 100 kinds of worm viruses, but still did not find the mutated rules of worm viruses. However, Shi Lei had discovered some clues and had some guesses in his mind.
But before Shi Lei had time to analyze further, Yi Zuer suddenly issued a warning.
"Sir, the Jade Building surveillance system found unidentified personnel, and the system could not judge the identity information of the relevant personnel." Although the entire Shuangqing City had a power outage, the Jade Building and the surrounding areas had the support of Mirui Technology Group and obtained the power supply.
Yi Zuer discovered unknown people through the security monitoring system of the Jade Building and entered the small square where the Jade Building was located. So he immediately reported to Shi Lei.
Shi Lei's face changed slightly, "It's finally here!"
Regarding these unknown people, they have only appeared now, and Shi Lei has almost guessed the reason for their late arrival, which is also a power outage in Shuangqing City.
The power outage is a double-edged sword. When there is no power outage, these unknown people cannot find relevant information in the Xia State Population Information Statistics Bureau. Once they enter Shuangqing City, they will definitely be targeted by Yi Shuer.
Therefore, when there is no power outage, they must stay outside the surveillance camera and wait for the power outage to enter Shuangqing City. Unfortunately, after the power outage in Shuangqing City, traffic was paralyzed. These guys who were ambushing outside the surveillance cameras covered in Shuangqing City may have to walk or use bicycles to enter Shuangqing City.
It is precisely because of the power outage that these unknown people appeared in the Jade Building after more than two hours of power outage.
"Yi Zuer, start killing!" After Shi Lei issued an order to Yi Zuer, he continued to devote his energy to analyzing the worm virus mutation rules.
In the small square where the Emerald Building is located, more than a dozen unknown persons wearing black combat uniforms rushed to the Emerald Building. If they had night vision, they could find that they were holding pistols equipped with mufflers in their hands. And, around their necks, there were assault rifles equipped with mufflers.
Yi Zuer had already arranged automated war weapons in the Jade Building. Five improved second-generation steel numbers and five improved first-generation shadow dragons were ambushed on the roof of the Jade Building.
When the surveillance system of the Jade Building discovered an unknown person and stepped into the small square of the Jade Building, Yi Zuer reported to Shi Lei and activated the automated war weapons.
Whether it is the second generation of Steel or the first generation of Shadow Dragon, their flying noise is very small due to the use of electrical and silent design.
The ten fierce unmanned aircraft were equipped with the fourth-generation electromagnetic guns, which aimed at unknown identities on the ground in the air.
‘The second time the target identity is confirmed failed, it will be automatically determined as an unknown person…’
‘Image recognition engine information confirms that unknown personnel are equipped with thermal weapons and are classified into dangerous range…’
‘Confirm the killing permissions, confirm that they are completed, and have obtained the authorization of the system administrator…’
‘Countdown to three seconds, start killing mode, and the battle is expected to end in seventeen seconds…’
Inside the advanced pseudo-artificial intelligence system, the system makes logical judgments and then turns on the killing mode. The cross of automated war weapons suspended in control opened fire almost at the same time.
The fourth generation electromagnetic gun is comparable to the power of a medium-sized sniper rifle, and it also has an advantage in the initial speed of the projectile.
A series of air compression sounded, not attracting anyone's attention at all. But on the ground, ten unknown people wearing black combat uniforms suddenly fell to the ground.
‘The killing target data is confirmed, and a total of ten targets are killed, with a killing rate of 100%…’
‘Lock the target and prepare to start the second round of killing the target…’
There is a reasonable logical judgment within Yi Zuer's system. Although it seems like it takes a long time to describe it, in fact, this time is at the millisecond level. When the fourth-generation electromagnetic gun fires in the first round, the second round of fire comes immediately.
Only one person escaped when the remaining nine targets on the ground suffered the second round of attacks.
‘The killing target data is confirmed, killing eight targets in total, escaping one target, sending ebi-03 and ebi-04 to chase…’
ebi is the first generation of improved shadow dragons. The code name in Yizhuer's internal system is only used by Yizhuer. With Yizhuer's logical judgment, it was completed in less than 10 milliseconds, that is, within one percent of a second, two shadow dragons followed the escaped unknown person.
When the two shadow dragons and the escaped unknown personnel had appropriate shooting angles, Yi Zuer used the fourth generation electromagnetic gun without hesitation.
When the last unknown person fell to the ground, logical judgment information appeared again in Yi Zuer's internal system.
‘The battle ends, destroying nineteen unknown people, spending seventeen seconds, making the prediction correct, and reporting to the system administrator…’
"Sir, the crisis of the invasion of the Jade Building was lifted. The system killed a total of 19 unknown personnel. The following is the location of 19 unknown personnel who were shot dead. Please provide a solution." Yi Zuer showed the location of the bodies of 19 unknown personnel in the lip lens-type information processor.
Shi Lei shook his head and said carelessly: "I won't deal with it for the time being."
The invasion of the Jade Building was easily solved by Yi Zuer, but Shi Lei encountered great trouble when he analyzed the mutation rules of the worm virus!
