Chapter 566 The Strongest Virus in History

"wrong……"

Meng Fei sat in the mecha that was visualized by the anti-virus software, staring at the clean green on the screen.

Obviously the virus has been eliminated, why did his intuition tell him that he was too happy?
Probably because every time I played against the former big boss, I felt that I was too happy too early.So that the formation of psychological fear?
To be on the safe side, he pressed the button to open the hood.

The hood was opened, and the large screen in front of him was separated from the two sides, and his gaze directly saw the "real" world behind the screen.

"Old Li, open the hood and aim visually! The mech is infected, and the display on the screen is fake!"

Opening the hood, he didn't even need to scan, what he saw was a doomsday scene.

The entire turntable was already filled with an unknown number of Roan, just like the zombies of Dawn of the Living Dead, rushing towards the mecha group crazily.

"Fix! Fix! Fix!"

Within the range of Meng Fei's vision, the mecha was repaired, and the living dead Luo An disappeared in pieces.However, it was of no use.

Countless Roan still emerged from the area beyond his vision and behind the occlusion.

"Quick! Manual control, aim and shoot!"

Lao Li was also frightened crazy.

While repairing, Meng Fei used the joystick to control the machine gun, and shot randomly at the group of "Luo'an" brand zombies in all directions.Bullets rained down, and flesh and blood flew everywhere.

Twelve Gatling Bodhisattvas spun wildly, harvesting viruses one by one like a sickle.The originally black and white world suddenly flowed into rivers of blood, and corpses littered the field.

But does it work?not at all!
The main cycle of frenzied rotation seems to be fertile soil watered by flesh and blood.One "Luoan" fell, and thousands of Luoan crawled out of the ground like evil spirits, densely packed and continuous.

The virus started a berserk replication mode.

In the previous dual or triple backup, they still need to monitor each other, and only generate new instances when they detect that the other party disappears.

Now he obviously changed the algorithm to create new clones directly regardless of Sanqi 21.

But no matter how he changes, the principle is the same, even no different from viruses and cancer cells in the real world, that is, to keep replicating itself.

Unless he can be eliminated all at once, there will always be more and more of him.

But Meng Fei couldn't figure it out.Obviously, all the viruses have been cleaned up when the single step is turned on, why do these viruses still exist?
It's like you turned off the machine, formatted the hard disk, reinstalled the system, and turned it on, but the virus still greeted you cheerfully.

That kind of frustration is simply the nightmare of life.

"You have already lost, don't you understand?"

Roan climbed onto his open hatch, his eyes were serious and indifferent, as if he was scolding this former subordinate.

"Yeah, I don't understand!
"The system has stopped, and the virus cannot get a chance to execute. Why is it still not wiped out?"

Meng Fei eliminated this Luo An through "repair".But the other two Roan appeared directly next to him, one left and one right, and answered him:
"It's very simple. Antivirus software has loopholes. It's just a simple buffer overflow attack."

Roan on the right was talking, while reaching out his hand, as if to touch his head.

"repair!"

Meng Fei once again eliminated Luo An on the right with repair.Under the reminder of the boss, he finally understood what was going on.

Yes, killing soft is also loopholes!
When he stopped the system step by step, the antivirus that Lao Li later brought in was not within the range of stopping, and could still work.

Then the antivirus starts to scan for all viruses.

But killing soft also has loopholes.What if you knew about these vulnerabilities and crafted a piece of pre-embedded data into the virus?
Antivirus will scan and analyze this data.But because there is a loophole in the antivirus software, a buffer overflow occurs when some data is read into the buffer for parsing.

The overflowed data is written to the stack and overwrites the original return address.Then when the function returns, it runs to the illegal instruction area pointed to by the new address in the stack.

The result is that the virus, which was impossible to get a chance to execute, uses the antivirus itself to run.

In the end, the virus was not cleared in a single step!
Luo An on the left is sternly teaching his former disciple:

"Since we want to write this virus, we must consider the situation of being attacked by antivirus software.

"All the antiviruses in the world are buggy, and no one can stop you from analyzing them.

"Prepare attack code for all vulnerabilities. Any anti-virus software that scans this virus will be infected by the virus."

"repair!"

Luo An on Meng Fei's left was also cleared by him and disappeared.

According to Luo An, in order to prepare for this virus, he studied all the anti-virus software in the world-in fact, this is not difficult.

There are only a handful of antivirus software in the world.Vulnerability analysis is the job of this genius hacker.He started his career in the information security industry by analyzing vulnerabilities.

So he easily wrote the strongest virus in history, specially designed for antivirus.Any antivirus that scans and tries to kill it will be infected by it!
There is no way to deal with such a virus.

As long as you get an antivirus that he hasn't analyzed, even if you temporarily write a shoddy substitute, the traps he laid in advance will be useless.

But now it is obviously too late.

Roan on the left was eliminated, and Roan on the right reappeared.This time he finally managed to touch the top of Meng Fei's head.

The virus touches my head, and I will live forever!
Meng Fei felt something entered his consciousness.

"Could it be that your computer virus can even infect human brain consciousness?"

This made him even more incomprehensible.

"Psychicism" like origin scholars need their own cooperation.It is equivalent to describing your own consciousness to the other party.

A master like Suzaku can "surprise" the opponent's consciousness, but it also requires a process of induction. It is not free to come and go, and can only be used in situations where the opponent does not know how to guard against it.

But this one written by Roan is just a computer virus, but it can freely infiltrate his brain?how can that be?Isn't this too unreal?

Our novels are absolute realism, it is impossible to mess around like fantasy novels!
"There is no essential difference between human brain consciousness and programming.

"It's just that the development of originology has not yet reached the point where it can successfully interpret human consciousness."

Luo An first shook his head in disdain, and then a little disappointment appeared in the corner of his eyes, obviously dissatisfied with the origin or the speed of technological development.

"But we are all familiar with the original code of the world. Especially if you have a program written in the original code in your head.

"Although I can't directly infect your consciousness, the program that infects you is fine.

"Through it, it can also have a certain influence on your consciousness."

Meng Fei understood.

It's BUG. EXE!

This is written by Suzaku in original code.Roan just saw it once in the spiral of time, and saw through its loopholes?

It was actually infected by a virus written by this godlike human being!

***
(I actually wrote anti-virus software before. But it didn’t take long, and I switched careers and rewrote something else after only two years of writing.

These chapters feel like recalling the eventful years of the past, and the writing is very refreshing.

Recently, I remembered a sentence that a former colleague (this person developed the 360 ​​first aid kit) said to me: "You will never imagine how insignificant the means of those viruses will be."

Yes, a very interesting industry, carrying a short but interesting part of my life.

It's a pity that that industry has completely declined, and mobile phone manufacturers have confidently destroyed it.

You will no longer see antivirus software on your phone.But the virus is always there, it's just more stealthy.

Because mobile phone manufacturers deprive security software of all permissions, and then leave the loopholes to those virus authors who are getting more and more wretched in hidden corners. )
