After Lao Wang unzipped the file, he couldn't help but say excitedly: "Judging from the name of the file, it should be right, it is the battle plan document of the Blue Army!" ”

When Captain Qian heard Lao Wang's words, he was already smiling from ear to ear. Pen, fun, pavilion www. biquge。 info

The problem encountered now is that this file has been encrypted, and Captain Qian immediately asked Lao Wang to check the specific situation of the document, and fortunately found that the other party did not encrypt the file twice, but only encrypted it when the exercise headquarters prepared it before.

They didn't know that within a minute after the worm copied the document, Li Yushan started to encrypt the file, and as long as it was slowed down for such a minute, their results were likely to be greatly reduced.

"Lao Wang, are you sure to crack it? If it can be done, the exercise will be considered a successful conclusion. Haha, the Blues are lost! Captain Qian's smile never stopped.

In fact, many people think that there is no suspense in this exercise, after all, the strength of the Blue Army is there, whether it is the overall military quality or equipment, it is a few streets away from the Red Army. However, in the face of their clamour, the commander of the Red Army, Lao Yuan, did not believe in this evil, could not stand the stimulation of the other party, and directly bet with them that whoever loses, the officers above the rank of army commander will run naked!

Captain Qian resisted the urge to report the good news to the command immediately, and looked at Lao Wang expectantly.

Lao Wang didn't say much, but said: "I'll try it, it should be no problem!" ”

"Good!" Captain Qian gave a thumbs up to Lao Wang and said. "Lao Wang, thanks to this exercise, I was able to successfully obtain the opponent's combat documents, which is not easy! If we can win this exercise, Lao Wang Ling will be the great hero of our information confrontation brigade and our 38th Army! ”

Captain Qian said this, which made Lao Wang a little embarrassed. He hurriedly explained: "Captain Qian, it was not me who played a major role in the success of this operation. It's Lin Hong. I'm just cooperating with his invasion, and the real main force is him! ”

Although the worm was written by Lao Wang, the key part was completed by Lin Hong. If he hadn't done the key parts of the code, Wang wouldn't have been able to do this.

Moreover, the reason why this worm was able to successfully infect the opponent's server was also the vulnerability provided by Lin Hong, and the foreshadowing attack in the early stage was completely completed by him. Lao Wang is not a person who sells fame and reputation, so he naturally refuses to take this credit on himself.

Captain Qian nodded, Lin Hong's role, he also saw it, but he didn't expect it before. In this matter, Lin Hong actually made the main effort, after all, this worm, in his opinion, has always been in charge of Lao Wang, and even the information sent back. Also on his computer.

He looked around, but didn't see Lin Hong's figure, and didn't say more, just asked Lao Wang to quickly crack the contents of this document.

Then, Captain Qian ran to his office with brisk steps and reported the good news to the above.

Probably considering that this is the first time that an information security confrontation exercise has been conducted. When they prepared this encrypted file, they did not use the asymmetrical almost impossible way to crack it, but used conventional encryption, that is, as long as the technology reached a certain temperature, it could be cracked.

Lao Wang is from a virus research background, so he naturally no longer has a problem with this level of cracking work.

He skillfully opened the tool and began to analyze the structure of the file, break points, and track the algorithms in it.

Everyone was naturally very happy to see this result, after all, they had worked hard for so long, just for this purpose, and now they had unconsciously completed it ahead of schedule, except for some disbelief, it was a burst of ecstasy.

It was the first time for everyone to experience this type of exercise, and although there were still many deficiencies in many aspects, they had experienced a lot of things in the past week, and they had also encountered many situations that they could not normally encounter.

Especially the performances of Lao Wang and Lin Hong, they were simply amazed, although they didn't do it themselves, but they were able to feel the process in person, which also made them feel very excited, after all, being able to work with masters is a thing to be proud of.

They didn't know how Lao Wang and Lin Hong "stole" each other's documents back, Lao Wang was cracking the files, and they couldn't bother him, so they gathered around Lin Hong and asked about the details of this invasion.

After working together for so long, everyone is a comrade-in-arms with each other, and it is difficult to be warm, and in the face of their questions, Lin Hong could not ignore them, so he briefly explained this principle to them.

Don't say it, don't think it, but when Lin Hong finished explaining, everyone was completely stunned by their whimsy.

Write your own worms, system vulnerabilities, Apache overflow vulnerabilities, hide, cover, secretly transmit......

They seemed to have heard a thrilling spy war story.

They never imagined that they would be able to use this method to hack into each other's systems and steal intelligence. Until then, they didn't think about it, and many people's concept of network intrusion was only at the level of using software or exposing vulnerabilities.

The case that Lin Hong said was an eye-opener and shocking to them, and it also changed their consistent view of cyber intrusion.

This is the invasion, this is the contest between the masters!

Everyone was amazed by their ingenuity, and they were even more amazed that the invasion had been successfully completed.

When they returned to their seats, they couldn't calm down for a long time.

This experience had a great impact on their later path in computer science.

Especially Liu Hui, he now suddenly realized how naïve and ridiculous his previous behavior was. Only at this time did he fully understand that Lin Hong ignored his challenge before, not because he had a good temper, nor because he was not good at arguing, but because the other party did not treat him as a dish at all.

Lin Hong's technique has long been beyond how many levels he has, this is like, a hero with peerless martial arts in the martial arts, in the face of children's provocations, can only ignore one way.

"It turns out that hacking technology can be so thrilling and so exciting......"

Liu Hui seemed to have matured a lot in an instant.

……

……

In the next period of time, the atmosphere in the computer room was obviously much more relaxed than before, and everyone could often see a relaxed and comfortable smile on their faces.

Since they have already obtained the opponent's combat documents, as long as they ensure that their side does not have the documents taken by the other side, they can basically win this exercise.

They are now fully on the defensive.

Captain Qian also became more leisurely, and from time to time he was seen running to Lao Wang's side to see how his cracking was progressing.

Lao Wang was a little anxious at this time.

This encryption algorithm was a bit unexpected by Lao Wang, he originally thought it was similar to cracking a simple software, but he didn't think that the army would put it in the encryption area, but there were real masters.

Although the algorithm is simple, the encryption method is quite complex, so it can be said that the other party purely uses encryption techniques to increase the difficulty of decryption.

Fortunately, Lao Wang has now found some clues, and it is only a matter of time before he cracks it out.

When Lao Wang encountered a problem, Lin Hong did not take the initiative to come over to help, after all, Lao Wang did not ask him for help.

It was the same before, if Lao Wang hadn't asked him for help, he would never have taken the initiative to come forward and say that he could solve this problem.

Technicians have a certain amount of pride, and they never give up easily when faced with challenges.

In addition, it is understandable that Lao Wang wants to crack this file. After all, his previous achievements were all completed with Lin Hong's assistance, and in comparison, the role he played was not as good as Lin Hong's.

It is only a matter of time before the file is cracked, and the exercise is nearing the end by this point, after all, according to the plan, the total time is ten days, and tomorrow is the deadline.

Captain Qian stayed at Lao Wang's side for a while, and after saying a few words to him, the smile on his face became even bigger, he should have received good news from Lao Wang.

Then, he came to Lin Hong's side and said to him: "Comrade Lin Hong, the exercise is almost over, but I am wondering, is there a way to give the Blue Army another painful attack and draw a successful end to this exercise?" ”

Lin Hong thought for a moment and asked, "Denial-of-service attack?" ”

Captain Qian high-fived with a punch: "Okay!" Just use a denial-of-service attack! It's best to disconnect them all from the internet and not be able to connect to the network. Of course, let their servers deny service! ”

He secretly had fun in his heart, this exercise, even if he invited two top masters, especially this Lin Hong, he could also understand that this young man did not do his best at all, and he was very comfortable with this level of exercise.

He just came over and tried to say it, but the other party really still has the means to come out.

People are in good spirits on happy occasions, and Captain Qian hummed a song and left.

Lin Hong's work, he was quite relieved, he didn't need anything he told at all, he could finish it beautifully. He actually sighed mentally many times, why is Lin Hong not his soldier? If there is such a soldier, how much worry must be saved!

Lin Hong couldn't help but smile and shake his head when he saw Captain Qian's happy look, and then began to prepare for his attack.

The reason why he agreed to Captain Qian to carry out the last attack and draw an end was actually a certain amount of selfishness.

After all, he had been working on the "Border Gateway Protocol" for so long, and he had some experience so far, and now he took this opportunity to test the newly discovered vulnerability.
