Back in the office, Qin Shouren took out a few blank work orders and handed them to Hu Yifei, "If someone comes again, you can work by yourself, just remember to let them sign after finishing your work." After explaining this, Qin Shouren left.

In the afternoon, the computer of the director of the Municipal Tobacco Bureau malfunctioned, and Hu Yifei filled out the work order by himself and went. When I took a look, it turned out that the interface of the CPU fan was loose, and the fan did not rotate, causing the CPU to overheat and restart back and forth, Hu Yifei replugged the wire, and the computer was normal, such a simple thing, it was done in three minutes, and 50 yuan was in hand. Before leaving, the people from the Tobacco Bureau forced Hu Yifei to a cigarette.

Dongyang's promotion of information security reform, although it seems a little troublesome, but the original intention is still good, that is, to prevent the loss of confidential information in all links. Although the repair is only a small matter, if you find someone to fix it, you may be manipulated in it, and even the nude photos incident will happen.

Of course, Dongyang City has a long-term plan, the next step, they are ready to implement the ISO information security system standard in the city's administrative network, all links must be built in accordance with ISO standards, after completion, the operation of all links of Dongyang City's administrative network will become a standard to follow, greatly improving the security surname and standardization.

Hu Yifei returned to the dormitory, and began to search for all the information about the shadow file on the Internet, as Cobra said, many people have heard of the shadow file, and also know the theory of the reflection on the water surface, but those who really understand the implementation principle of the shadow file can't find half of it, which makes Hu Yifei very depressed.

Just as he was getting upset, the tarantula sent a message, "Dr. T's test is back on!" ”

Hu Yifei was a little strange and asked, "Didn't it start a few days ago?" ”

"After the ZM attack, the test was closed and reopened today!" After the tarantula finished speaking, he added, "The strange thing is that instead of launching an attack this time, ZM also issued an announcement that ZM is also going to participate in Dr. T's test!" ”

"What are they doing here?"

"I don't know!" The tarantula was a little sad and said: "But if they want to participate, the 100 million US dollars will belong in advance, and ZM's strength in the industry is unmatched!" ”

"Where did you get the news?" Hu Yifei was a little unconvinced, "Aren't they afraid that Dr. T's test is just a trap?" ”

"ZM's announcement was published on their entrance server! As for the trap, I don't think it's possible, Dr. T is not a trapper, and he can't play this joke on everyone. Besides, even if it is a trap, ZM is not afraid, because there is no one to hunt them down, and they escaped five years ago under the joint pursuit of Dr. T and American agents! ”

I can't catch up with him before I die, but I can't catch it after death, Hu Yifei sighed, in the Romance of the Three Kingdoms, Zhuge Liang went out of Qishan six times before his death, and he couldn't kill Sima Yi with all his efforts. Thinking so in his heart, Hu Yifei opened ZM's entrance server and prepared to pay tribute to ZM's announcement.

Open the zm entrance server, Hu Yifei found that this place has been revised, in the past, it was a simple page, to receive test identity tokens, query identity tokens, and query the customs clearance rankings, but now it is like a studio's website, with news release content.

Hu Yifei found ZM's announcement, and ZM said that he had only one reason for taking the Dr. T test, and that was that they respected this opponent.

"!" Hu Yifei won't believe these nonsense, if he really respects it, then he won't retaliate before, it's already good to hate Dr. T!

After turning off the ZM announcement, Hu Yifei sent another message to the tarantula, "I have already consulted my teacher about the shadow of the program!" ”

The tarantula hurriedly asked, "How is it, what did your teacher say?" ”

"Instead of explaining to me the Shadow of the Program, he brought up something called the Shadow File, do you know what it is?" Hu Yifei got back to the point.

"Shadow files are a strange way to hide files, but few people use this method, because once you put what you want to hide in the shadow folder, no matter what method you use, you can't find the existence of the file."

"Is there a way to get the contents out of the Shadow folder?"

"Unless you know the name of the document in advance, you can't figure it out! If you touch the shadow folder in any other way, the data inside will disappear and can never be recovered, as if the data never existed on the hard drive, and the data in the shadow file will not leave any traces on the hard drive, which is why they are called shadows. However, if you forget the name of the contents, you won't be able to take them out either! ”

"That's right!" Hu Yifei finally got a definite answer, and like his own conjecture, knowing the name of the document can really find out the document.

This reminded him of a kind of witchcraft in ancient times, where the wizard put a lot of small figures cut out of paper in front of him, and then began to call names, and the little people who were called by name would immediately stand up, and then they could talk and walk, exactly like real people. But if you can't name them, they're just pieces of paper that will fly away when the wind blows.

"Interesting!" Hu Yifei smiled and sent a message to the tarantula, "I don't think my teacher will bring up this matter for no reason, you think about it and see if there is any connection between the Shadow of the Program and the Shadow File?" ”

The tarantula asked Hu Yifei to put it in, and said: "I don't know very well the implementation principle of the shadow file, my teacher has mentioned the shadow file before, so I have an impression, I'll go back and ask him again!" ”

"Okay, let me know when you have news!" Hu Yifei is now accustomed to pushing everything to the tarantula to do, and he only needs to pick up ready-made ones.

The tarantula didn't delay much and decided to consult Sparker right away to see if there was any way to find any clues to the Shadow of the Documents.

Hu Yifei wandered around the Internet for a while, and when he went to look at the ZM entrance server again, he found that ZM had released a new announcement, they had successfully broken through the outermost server of Dr. T's test system, and got a letter from Dr. T, and ZM announced the content of the letter in the announcement.

"Is this respect?" Hu Yifei sneered, "This is simply Chiguoguo's show-off and humiliation, poor that strange old man's bones are not cold, he has already been whipped twice!" ”

Hu Yifei now finally knows how strong ZM is, from the time they decided to participate in the test to now, there was only less than an hour, but they had already broken through the peripheral server personally arranged by the strongest weird old man in the industry, Dr. T, it is hard to imagine that they could not go more than a round under Dr. T, and I don't know if Dr. T has regressed, or if ZM has improved?

Looking at the letter carefully, the style of the text is indeed very similar to those notes on the hard drive, and it seems that it is really Dr. T's own letter.

In this letter, Dr. T recalls some of the things he did before he was sixteen, many of which were first revealed in this letter.

Dr. T came into contact with computers at the age of thirteen and mastered at the age of fourteen, and there was nothing else to explain except the word genius.

At the age of fifteen, Dr. T became a hacker, and like other juvenile hackers, Dr. T was also young and frivolous at that time, he hacked into the military networks of the United States, Britain, France, and Germany, and left his own exclusive logo and backdoor. Many hackers in history have done this, but Dr. T is distinguished by the fact that until the computers were phased out many years later, no one gave him a damn about what he did, and the backdoors he placed worked until the end of his life.

Dr. T even said in the letter that if those hard drives were still preserved at this time, if they were more careful, they might be able to find the back door and logo they left behind, what a kind of conceit and self-confidence!

There is an even more terrifying thing, Dr. T said that he also wrote an email to the president posing as the commander of the U.S. military, and then wrote an email to the commander of the U.S. military by impersonating the president, and finally succeeded in controlling the work computers of the two people, until half a year later, Dr. T cleaned up the back door by himself, and no one found out during the period.

At the end of the letter, Dr. T summed up his life before the age of sixteen in one word, "fearless youth."

ZM publishes the letter to show off his own, but the letter looks more like a kind of self-show-off and self-appreciation of Dr. T, and even a little narcissistic.

The things mentioned in the letter may make some of the parties involved in the year instantly soaked with cold sweat, maybe some people will not believe it, and even some people will come out to refute the rumors and deny it, but all this is no longer important, because Dr. T has passed away, and many things are irrelevant even if they learn the truth, and the secret has been buried by the loess.

"What were you doing before you turned sixteen?" Hu Yifei sat there and thought about it for a long time, and then sighed, at that time, it seemed that he had been doing the problem memorization formula all day long, and when he was busy, he might sneak to the Internet café to secretly watch a piece of hair or something, in addition, it was a blank, and compared with the strange old man, it was really very miserable.

Thinking about it like this, Hu Yifei was a little depressed, his chin was supported by his arm, his eyes were fixed on the word on the screen, and his mouth repeatedly muttered "Fearless youth!" "Fearless Youth".

After chanting more than a dozen times, Hu Yifei suddenly sat up straight, if ...... If the things in the shadow file are called by this name, is it just called by yourself, and the things that Dr. T came out before he was sixteen years old?
