The worms that broke out in Shuangqing City's power grid system have ultra-fast mutation and self-reproduction speeds. This kind of worm is very troublesome, because it is difficult to find among so many worms that can actually damage Shuangqing City's power grid system.
If you don't know the worm's parent virus and don't know the mutation rules and signatures of the worm, it's like looking for a needle in a haystack.
However, it is still very difficult to analyze signatures and mutation rules from more than 1.2 million worm viruses.
‘Damn it, such a powerful worm cannot be written by those useless materials. Who wrote it?’ Shi Lei thought in his mind.
There are not many hackers with this ability worldwide.
Shi Lei personally participated in the work of analyzing the worm virus signatures and mutation rules. I am afraid that it is impossible to complete this difficult task just by relying on simple analysis.
Yi Zuer processed the code very quickly, and Shi Lei further analyzed Yi Zuer's analysis results. With Shi Lei's cooperation with Yi Zuer, in just ten minutes, Shi Lei had already analyzed the above results.
Thousands of worm variants.
Shi Lei gradually discovered a rule. In order to verify the idea in his mind, Shi Lei quickly tapped on the keyboard of Server No. 1 with his hands.
After a while, Shi Lei wrote an analysis tool and then ordered: "Yizur, use the analysis tool to analyze all worm viruses."
"Yes, private!" Yi Zuer immediately called the analysis tool Shi Lei had just written and began to analyze as many as 1.2 million. No, there are now more than 1.3 million worm viruses.
Following Yi Zuer's efficient analysis, five minutes later, a smile appeared on Shi Lei's face. He discovered the signature code of the worm virus.
This signature is not a worm signature, but a universal signature. Under normal circumstances, how does ordinary anti-virus software determine whether a program is a virus or a Trojan?
In fact, it is through the signature. As long as the signature of the program matches the signature in the virus database, it will be judged as a Trojan virus and will be isolated and deleted.
But this method is ineffective against worms in the power grid system!
Because worms in the power grid system are always mutating, hundreds of new types of worms will be added almost every second.
Each newly mutated worm virus has a brand new signature. If we analyze the signature according to traditional methods and then perform killing, the speed of killing may not be as fast as the speed of mutation and self-replication.
The signature code discovered by Shi Lei belongs to a general type of signature. It is equivalent to capturing the unified characteristics of the worm virus. No matter how the worm virus changes, its inner essence will not change. By locking the worm virus with the universal signature code, it can be eliminated.
them.
Once you have mastered the universal signature code, it doesn't matter even if there are no mutation rules. You can change it in seventy-two ways. But the essence is Sun Wukong. If you identify Sun Wukong, it doesn't matter what the appearance is.
"Yizur. Prepare to destroy these worm viruses!" Shi Lei wrote a special worm virus killing tool. According to Yizuer's processing speed, Shi Lei estimated that Yizuer plus the special killing tool would take up to ten minutes to kill the virus.
Then you can clean up the worm viruses in the entire Shuangqing City power grid system.
At present, there is no movement in Shuanghu District. Neither Jingyayuan, Cuihu Building, nor Jade Building has been attacked.
From this situation, Shi Lei deduced that in reality, the armed personnel targeting Mirui Technology Group should be outside Shuangqing City, at least outside the surveillance cameras.
They were waiting for the power outage in Shuangqing City before they had the opportunity to enter Shuangqing City. Now, their opportunity has come. There is a power outage in Shuangqing City. They can enter Shuangqing City without being discovered by surveillance cameras.
If Shi Lei now cleans up the worm virus in Shuangqing City's power grid system and restores power supply to Shuangqing City, then these armed intruders will be discovered by cameras.
Once they are discovered, Shi Lei wants to clean them up, which is no more difficult than eating and drinking.
In nearly ten minutes, Shi Lei compiled the worm-killing tool and worked with Yizuer to debug it. Shi Lei handed the special-purpose killing tool to Yizuer.
Yi Zuer immediately took control of the worm virus killing tool and carried out powerful killing in Shuangqing City's power grid system. It turned out that there were nearly 1.4 million types of worm viruses entrenched in Shuangqing City's power grid system. Yi Zuer
After using the worm-killing tool, the worms in the power grid system quickly disappeared.
This situation was also discovered by security experts from the Western Cyber Security Administration. Ling Yuguo immediately called Shi Lei.
"Shi Lei, have you discovered the mutation rules of the worm?" Ling Yuguo asked. Normally, to deal with this kind of mutated virus, you have to discover the mutation rules. According to the mutation rules, special killing tools are made to be effective.
Shi Lei denied: "No, Uncle Ling. The mutation rules of the worm virus have not been discovered yet, but a universal signature code with almost the same effect has been discovered."
"Oh? These worms actually have universal signature codes?" Ling Yuguo asked in confusion.
Shi Lei said with a smile: "It must exist. No matter how it mutates, it still follows a rule and has the same basic characteristics."
This principle is the same as biological variation. Take crabs as an example. Although there are many types of crabs around the world, crabs are crabs. Whether they are giant killer crabs that can kill people or hairy crabs that are eaten by humans, they are all crabs.
, cannot escape the category of crab and can be recognized at a glance.
Ling Yuguo is also a highly skilled security expert. After thinking for a moment, he laughed and said, "Shi Lei, how long do you estimate it will take to deal with the worm virus? We can inform the staff of the power grid system and let them adjust the power grid system.
thereby restoring power."
A super city with a population of more than 10 million has fallen into a total power outage. This is a huge disaster!
Some people may think that losing power will cause a catastrophe. Simply put, losing power means traffic is paralyzed. The traffic signal control system in Shuangqing City is completely interrupted, and the dispatch of the traffic signal control system is lost.
Traffic in Qing City is basically at a standstill.
Another one is the panic among the people, which is definitely a big problem!
If the power supply can be restored as soon as possible, Ling Yuguo's pressure will be reduced a lot. Otherwise, Ling Yuguo's pressure will be great, and he may still be criticized by the top management.
Shi Lei looked at the virtual transparent screen of the lip lens information processor, which showed the remaining countdown of the anti-virus time, and then responded: "It will take about fifteen minutes. If everything goes well, in fifteen minutes, Shuangqing City's power grid system will
, there will be no more worms."
Fifteen minutes was not a long time. Ling Yuguo breathed a sigh of relief and his tone became more relaxed, "Shi Lei, your kid's computer skills are actually so powerful?"
According to official information, Shi Lei's computer skills are not powerful at all!
"Uncle Ling, you are thinking too much!" Shi Lei deliberately smiled bitterly and tried to cover up, "Uncle Ling, this is a security expert from Mirui Technology Group, helping to deal with the problem."
Ling Yuguo asked curiously: "Shi Lei, a security expert from Mirui Technology Group, is in Shuangqing City?"
"Well! Uncle Ling, I can't say who they are, but I can tell you that their skills are not low." Shi Lei replied seemingly honestly.
"Them?" Ling Yuguo grasped the key point, "Did Mirui Technology Group send multiple security experts to Shuangqing City?"
"Hey, Uncle Ling, these are confidential information of Mirui Technology Group!" Shi Lei deliberately did not answer.
Ling Yuguo smiled and said: "You boy, given your relationship with Yumo, are you still on guard against me?"
"Okay, okay, Uncle Ling, I told you, please don't spread the word." Shi Lei said in a helpless tone, "Mirui Technology Group sent a total of two security experts, one of whom at least has the world's
Super-level skills, but this person is always looking up to another person. I said this, Uncle Ling, do you understand?" Shi Lei said pretending to be mysterious.
This is not Shi Lei's nonsense. Shi Lei himself is a world-class being. Tao Wenxian is a world-class being, and he can also be regarded as a world-class being. Moreover, he follows Shi Lei's lead.
So, Shi Lei didn't say anything nonsense, he just didn't disclose the specific identity of the security expert.
Ling Yuguo took a breath of cold air, "At least he is a world-class and top-level security expert, which can also be said to be a hacker. Your Mirui Technology Group is really generous!"
"Hehe!" Shi Lei smiled stupidly, looking harmless to humans and animals.
The two continued to chat, while Shi Lei checked the situation of Jing Yayuan, Cuihu Building, and Jade Building on the virtual transparent screen of the lip lens information processor.
However, what makes Shi Lei a little strange is that the multinational hacker coalition went to great lengths to kill Shuangqing City's power grid system, but why have the armed personnel they arranged not shown up yet?
Could it be that they just hacked Shuangqing City's power grid system to warn Yifan Dream Entertainment?
This inference was thrown out of Shi Lei's mind as soon as it appeared in his mind. The multinational hacker coalition spent so much energy to cause the power grid system of Shuangqing City to go on strike, causing a severe blackout in Shuangqing City.
, how could they not dispatch actual armed personnel?
"Pr, the worm virus in Shuangqing City's power grid system has been completely cleaned up by the system using a special killing tool. After a comprehensive and in-depth scan of the system, there is no worm virus left in the power grid system." Yizuer reported to Shi Lei.
However, Yizuer had just finished his report, and a sudden mutation occurred!
