Live broadcast: Starting from becoming a hacker to encourage learning

Chapter 106

Yuichiro Koizumi didn’t stop him.

Third attempt.

Use IPS (IntrusionPreventionSystem) to attack.

IPS technology can detect data traffic and drop malicious packets.

This method blocks attacks and throttles abusive packets to protect network bandwidth resources.

Result –

Fail!

Fourth attempt.

Use Smurf attacks.

Smurf attacks are very simple, and sometimes the simpler the attack program, the more stealthy it is.

It has some list of IP (broadcast address) addresses, emits some bogus packets (ICMPechorequest) and causes a broadcast storm that can crash the victim virus source code (which makes it the source address of the spoofed packets).

Result –

Fail again!

Fifth attempt…

Fail!

Sixth attempt…

Fail!

……

The eighth attempt…

Fail!

……

The thirteenth attempt…

Fail!

……

The twenty-fourth attempt…

Fail!

Yuichiro Koizumi and the members of the expert group were almost in despair.

This virus detection system is too sensitive!!

They almost just probe it, and before they can attack, the virus built-in program will be triggered!

It wasn’t until the twenty-eighth attempt that Yuichiro Koizumi finally saw hope again!!

Meterpreter attack.

Meterpreter is a killer feature in the Metasploit framework, which is usually used as a post-vulnerability attack, which can be returned after the attack triggers the vulnerability, giving us a control channel.

The biggest advantage of a Meterpreter attack is that it can control a Trojan virus puppet to attack the virus defense system.

Now, the Trojan virus they control can indeed approach and even attack the defense system of the No. 1 virus.

Yuichiro Koizumi and the members of the expert group were very excited, they felt that they had discovered the loophole of the Punishment No. 1 virus!

“Attack!!”

“Destroy this virus!”

“I’ve had enough!I want to vomit now when I see the game interface of Hit Sun!!”

“……”

The experts are like crazy demons at this time, they have indeed been forced to be anxious!

It’s so uncomfortable!

……

They were thrilled and happy when they found this Meterpreter attack useful.

In their excitement, they began to attack.

This attack was not detected by the defense system of Punishment One, and then the game interface of Hit Sun was forced to pop up.

This time it’s real, hack into the interior of the Punishment One Virus Defense System!

This discovery made them even more excited.

“It worked! it worked!!This time it finally worked!!”

“It seems that this virus is not omnipotent. ”

“It’s already very good that the people of Xia Guo can do this together. ”

“We have finally found a way to crack it, and we can continue to attack the Xia Kingdom!”

“Gotta kill them. ”

The experts of the Sun Country, the previous decadent temperament has been swept away!

Instead, there is a sword-like fierce aura, exuding the domineering spirit of competing with anyone.

Yuichiro Koizumi also showed a relieved smile.

These efforts have not been in vain!!

He said, “Keep attacking!!Attack this defense system and destroy their source code!!”

“If we can really completely collapse this virus, we can make a unified cracking software!”

“Then this virus will be completely eliminated from the territory of our Sun Country!”

The experts responded.

And then—

Hands on the keyboard with a quick tap!!

Lines of code, commands are quickly output, and then executed.

Yuichiro Koizumi was also acting at this time.

He used Meterpreter to control Trojan virus software and was able to easily breach Punishment One’s defenses.

After breaking through the defense system of Punishment One, Yuichiro Koizumi found its core code in the core of Punishment One!

When he saw the core code, Yuichiro Koizumi looked at it for the first time.

He finished reading the core code of Punishment One, and then said incredulously, “It’s so simple!?”

“How could such a simple core code have such a powerful detection system. ”

“You know, so many of our previous attack methods have been successfully detected by it!!”

“There isn’t a very powerful detection system built into this defense system!?”

“It’s obviously impossible to do this!”

Yuichiro Koizumi’s eyes widened, his eyes full of incredulity.

He really couldn’t have imagined!

Why such a simple source code!

Such a rudimentary defense system.

How did such a rudimentary detection system do this?

Such a rudimentary detection program is only composed of a few dozen lines of code-

How did he do it?

How did he manage to keep all of their attack programs out of the virus defense system!?

Yuichiro Koizumi didn’t understand.

He was already confused.

He thought that he was already standing on the fifth layer, but he didn’t expect that the people of the Xia Kingdom had already stood on the eighteenth layer.

Yuichiro Koizumi can’t understand how the people of Xia Guo did this.

He looked up at the big screen.

“Master Su Susu” on the big screen, his eyes are cold through the screen, looking here.

The face is still unclear.

However, Yuichiro Koizumi could still feel that the other party was watching him.

The corners of his mouth sketched into a smile and gave him a sneer!

Yuichiro Koizumi knows-

This virus’s defense system can keep them out of the virus for so long.

It’s no longer a simple, ordinary.

It’s a miracle!!

Yuichiro Koizumi’s face was gloomy and uncertain.

He couldn’t figure out how the people of Xia Kingdom did this-

However, it doesn’t matter anymore.

Yuichiro Koizumi built the virus software into the core source code of Punishment One.

Soon, the virus crashed.

The whole software, like a piece of broken glass on the computer screen, began to shatter with a “bang”.

This virus has been successfully cracked.

Yuichiro Koizumi smiled lightly.

Even if this virus is very powerful and weird at first!

However, they still cracked it!

That’s the case.

The Punishment No. 1 virus, which has already invaded the entire official system of the Sun Country, no longer has any threatening power.

They can carry out a counteroffensive against the Xia Kingdom.

Yuichiro Koizumi thought to himself, and Xia Guo’s strength was like this.

After the victory, his mentality returned to pride.

Yuichiro Koizumi smiled.

At this time, members of other expert groups also came with good news.

“Koizumi-kun, we have also broken this virus!!”

“Koizumi-kun, we’ve also broken the virus!!”

“Koizumi-kun…”

The continuous good news makes everyone more excited.

They know that there have been so many cases, which means that this cracking method can be used on a large scale.

Xia Guo’s final attack was no longer of the slightest use.

Viewers around the world saw this scene through the live broadcast. ？

The Eagle Country, as well as some experts and professors from the Sun Country, all jumped out at this time and shouted: “The Sun Kingdom has never worried about the Xia Kingdom’s counterattack before! The Xia Kingdom’s attack is just the last struggle before death. ”

“We have long foreseen the outcome of this war, and there is not the slightest suspense, so naturally we don’t have to worry. ”

“The previous accident was just that we gave Xia Guo a little hope, gave them a little hope, and then made them completely desperate, it’s not that our Sun Country really can’t do it!”

“How can a mere Xia country be compared to our Sun Kingdom!?”

“The Sun Kingdom will win!!”

“The Sun Nation will win!!”

“……”

Before, they were really a little scared.

However, with Yuichiro Koizumi’s counterattack at this time, they successfully saved their face.

The host, who likes to watch professors being slapped in the face, is not easy to refute at this time.

After all, the facts are here.

At present, the virus has not posed much of a threat to the Sun Country.

Xia Guo could only be forced to defend.

Now Xia Guo’s last means of attack is gone!

Before, for Xia Guo, the best ending was to lose both.
