Blues Information Confrontation Brigade. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Li Yushan was frowning and looking at the picture displayed on the monitor.

What is shown here is the greatest achievement they have achieved on this occasion, and 85 percent of the Red Army's operational plan documents have been transmitted.

Ever since Li Yushan found out that the other party was using a bit messenger, he had been thinking about how to successfully obtain the opponent's battle plan document.

Conventional means will definitely not work, the other party does not open the web service at all, nor does it open the ftp service, and directly uses the application of bit messenger for file transfer, even if they want to intercept the intermediate data flow, it is impossible, because these data, will not all be transmitted from a node, but in the p2p protocol, received from multiple clients, monitoring a client is of no help at all, just a small part of it.

After thinking about it, he finally decided that he could only use social engineering to "trick" the documents.

To this end, he used several underlying vulnerabilities he had previously studied, analyzed the characteristics of the other party's data, and found a suitable target.

Things are moving forward step by step towards the script he had prescribed.

Unfortunately, just when he thought that the plan was not to be completed perfectly, an accident occurred, and the other party cut off the transfer of files.

He knew that it must be the master of the other party who discovered his plan, the loophole of his plan was too big, and he could only rely on luck in many aspects, although his luck had been good in the previous steps, but it had reached the most critical step. His good fortune seems to have run out.

Eighty-five percent ......

Li Yushan showed a wry smile on his face, he was only a little bit successful, but in the end, he fell short.

These 85 percent of the documents are simply indistinguishable from 0.

The final data received is a completely meaningless pile of code.

Not to mention that the characteristics of the transmission of the bit messenger file are that the fragments will be assembled only after the final transmission is completed, but Li Yushan analyzed the information in the head of the file and found it. The other party also appears to have encrypted the files and is asymmetrical.

"It's really watertight!" Li Yushan shook his head helplessly.

This exercise is carried out here. It's almost the end.

It can be said that both sides have their own merits and have achieved certain results. At present, Li Yushan is not sure which side has scored the most points.

Although from a technical point of view, the Reds seem to be a little more powerful, but they are not bad at all, and they do not give each other any chance at all.

After the server was attacked and restarted, Li Yushan asked Ding Huahui to decisively give up the apache that might have vulnerabilities, and instead used a set of FTP software written by himself for communication, and even the ports were modified, and if you didn't dig deeper, you couldn't sweep it out at all.

Moreover. In order to be on the safe side, after the system was attacked, he immediately processed the combat file on the disk, and the hero saw the same thing, and he also encrypted the file twice. The asymmetric encryption algorithm is also used, and the previous encryption algorithm is somewhat simple, and it may be easy for the other party to crack it by debugging the tracking software.

"The next thing we have to do is try to hold our own line and hold on until the end of the exercise. Then look at the end result. I think that even if we don't win this exercise, the score will be about the same, and it can be said that it is evenly matched. Li Yushan said to the captain of the Blues' information confrontation brigade.

……

Since the worm was transferring files, the exercise entered the most critical stage, and Lao Wang did not have the heart to sleep at all, he kept in front of the computer, carefully maintaining the connection.

In order to prevent these transmissions from being discovered, every once in a while, Wang would stop the connection for a while to allow it to be nearly disconnected, and then re-release the speed limit to make it reach the same rate as normal packets.

After Captain Qian learned the news, he also stayed here and stayed inch, sitting directly next to him and looking at the progress bar above, scrolling forward step by step.

At his behest, the others continued to attack all the Blues' machines, and the flood attack was certainly indispensable, and the senseless scanning did not let go, anyway, as long as the other party could generate a response packet.

It can be said that this worm, which currently pins all the hopes of the Red Army, depends on this worm whether it can win this exercise.

Lin Hong did not stay by the side all the time, but continued to study his newly discovered border gateway protocol vulnerability in this Cisco router.

Since the worm program still works, he doesn't plan to think about new loopholes, let's study this vulnerability first, after all, this vulnerability is new, and it seems to be very interesting, so it will be regarded as a "fake public benefit", anyway, he has also made a lot of contributions to the Red Army.

The progress bar in Wang's computer monitor scrolled forward unhurriedly.

1%、1.5%、3%、9%……

The expressions on the faces of Lao Wang and Captain Qian also changed with the growth of the progress bar, their mouths grew faster and faster, and their eyes narrowed more and more......

The computer room at midnight is quite quiet, and the sound of the fans inside the server and computer case is exceptionally clear.

Not far away, from time to time, the rhythmic snoring of a member of the information team was heard, accompanied by the sound of other members tapping on the keyboard.

The progress bar in the monitor finally came to an end under the eager eyes of Lao Wang and Captain Qian - one hundred percent!

"It's downloaded!" Lao Wang couldn't help but cheer.

"Haha!" Captain Qian finally burst out laughing, and the sudden increase in decibel immediately woke up the other team members who had fallen asleep, and some other people who were working were also attracted by his laughter and looked over to this side.

"Captain, what is it that makes you so happy?" Someone asked confusedly.

"Did you get any more results?"

"It should be more than that, I didn't see the captain so happy when I got those results before?"

"Is it ......?"

Everyone looked at each other, as if they had thought of something, and immediately rushed over.

Captain Qian hugged Lao Wang's shoulders fiercely, and said eagerly, "Let's see if it's the other party's battle plan document!" ”

Lao Wang immediately opened the download directory and found the latest downloaded file.

This is a compressed file, and I saw that Lao Wang quickly unzipped it, revealing the final file name.

He said with some excitement: "Judging from the name of the file, it should be right!" ”
