Hu Yifei didn't go to class for the third day in a row, and when he got up in the morning, he began to tinker with Dadao Technology's servers. This is a hard work, Hu Yifei basically did it step by step according to the steps written on the tarantula material, and he had read it several times before, but when it was really time to use it, he found that he had forgotten it all, and he still had to do it according to the "manual". It seems that hackers can't comprehend this thing in their heads, and they have to see the real chapter under their hands.

After half an hour, Hu Yifei finally got the external network into the internal network, and he was already able to see the internal machines of the Dadao Technology Enterprise, and now he just hadn't gone to work yet, and he searched out several computers on the intranet, all of which were very important machines, and these machines would generally run 24 hours a day, and they would not be shut down except for routine maintenance.

The tarantula material writes that there are many ways to hack the machine into the intranet, eavesdropping account passwords are the most reliable, stallions are the most effective, and remote login methods are not good, because the personal operation system generally does not allow multiple users to log in at the same time.

The stallion is poisoned, Hu Yifei will not do the same, remote login only uses the artifact, the restrictions mentioned by the tarantula are not applicable to the artifact, before monitoring Duan Yu Xiaoli's computer, they also installed a personal system, in front of the artifact, there is no multi-user login restriction at all.

Hu Yifei thought about it, then quit the server of Dadao Technology, and first found a file shredding tool from the Internet, which is exactly the same as the one Zhao Bing used last night, Zhao Bing is a master, he uses this tool to smash files, it should be reliable.

After pondering the process in his heart, Hu Yifei was ready to do it, first use the artifact to enter the gateway server of the avenue, then download the artifact, link their intranet computer, and finally smash the artifact and clean up the Zhi.

"That's not right!"

Hu Yifei was just about to link, and then remembered a very important thing, once the artifact enters the working mode, he will not quit, and he can't turn it off again! In case there are hundreds of computers on the intranet of Dadao Technology, if you are unlucky, you will have to turn off all the computers to find Zhao Bing's computer.

"Ahh Hu Yifei grabbed his head and planned his own action for a night, but he failed before he could act. Only then did he realize that having an artifact was not even as good as those little hackers with solid basic skills, he had an artifact and could handle everything, but he couldn't handle the intranet machine alone, unless he was in the other party's intranet! Looking back, the method provided by the tarantula at that time was the most reliable, but it was a pity that he believed in the artifact too much, so he wasted so much time in vain.

Hu Yifei doesn't want to continue to tear up with Zhao Bing now, even if he uses the method of tarantula, he may not be able to succeed for a while, and if he is not proficient in using it, if he exposes the stuffing, it will be even more troublesome.

After thinking about it for a long time, Hu Yifei started the idea of these intranet computers that he had searched out so far, and he decided to turn off the computer once to see if he could get any information from the other party's computer, and finally, he chose a computer named xx.

Using the artifact on the other party's gateway server to connect to the intranet computer is a bit of a two-layer springboard, Hu Yifei thought so, and saw the picture of the xx computer.

Without saying a word, he went directly into the work mode, Hu Yifei flipped through the computer, hoping to find some clues, all the disks were rummaged through, and finally only found a directory of employees, which was still a little useful to Hu Yifei, and the rest were all kinds of information and reports of Dadao Technology Company, for Hu Yifei's purpose, these have no value of use.

Hu Yifei flipped through and found Zhao Bing's information in the employee directory, with photos, contact information, and even Zhao Bing's home address, Hu Yifei was overjoyed, ready to write these down, and then thought about it, he didn't come to cut people, what's the use of remembering these?

Unable to think of any good way for a while, Hu Yifei packed all these employee directories and sent them back to his mailbox.

I flipped through it again, and there was no gain, Hu Yifei secretly said that he was unlucky, so he cleaned up Yue Zhi, turned off the xx computer, and then smashed the artifact on the gateway server, and after cleaning up Yue Zhi, he evacuated Dadao Technology Company.

Hu Yifei flipped through the list of employees on his computer again, but still had no clue, so he had to give up for the time being, and instead pondered how to break Zhao Bing's online album, which contained photos of his own women, all of which had to be deleted.

Brute-force cracking of passwords is too time-consuming, and even if you get one, it's not very useful, because Hu Yifei had already found out last night that Zhao Bing is very deceitful, and uses three passwords on domain name management websites, mailboxes, and network albums, and he counted them carefully, and the lengths of the three passwords are different.

"Then use the old business!"

Hu Yifei used the artifact to connect to the server of the network album, and with the experience of making carrots, he found the address of the database in the code familiarly, and he now feels that the book "Website Architecture" is too useful.

Opening the database, Hu Yifei found Zhao Bing's account, but the password was encrypted and stored in the database. According to the book on the website architecture, such a password storage method is relatively secure, and the reason why it is safe is because these encryption algorithms cannot be decrypted in reverse, that is, when you see these encrypted characters, there is no way to decipher what the original real password is, and no matter how long the password is, it is 18 bits after encryption, and you can't know how long the original password is, even if it is brute-force cracking, it is undoubtedly more difficult.

When the user logs in, as long as the normal password is entered, and after the password is submitted to the website, it will be encrypted first, and then compared with the password saved in the database.

Remembering the last COBRA report meeting, he changed the administrator's password saved in the database, but if he changed Zhao Bing's password to 12345 directly in the data now, it will definitely not work, because after 12345 is encrypted, it will not be 12345, and the comparison will definitely not be successful at that time.

Hu Yifei didn't understand password encryption at all, but he had a lively brain, and immediately found out what could be used in this process: this encryption method must be one-way fixed, a fixed password, and the 18-bit characters formed after encryption must also be fixed, otherwise there is no way to make comparisons.

That is to say, if you can know in advance what kind of character 12345 is after being encrypted, and then replace the characters that already exist in the database with this character, then you can definitely compare the success of the password 12345 by entering it, and then successfully log in.

Hu Yifei was overjoyed with his idea, he flipped through the code of the website again, and soon, he figured out what the encryption algorithm was, which is a more popular general algorithm, called MD5 encryption algorithm, which is clearly explained in the code of the website.

"MD5 encryption", Hu Yifei's keyword was put into the search engine, and there were many results, including MD5 encryption, which can enter a password and display encrypted characters. Hu Yifei downloaded one, typed in 12345, and got an 18-bit character, which is very similar to the dense characters in the database.

Hu Yifei re-entered the other party's database, and in order to be on the safe side, he first recorded Zhao Bing's current password characters, and then replaced his own characters.

After saving, Hu Yifei logged out of the database, began to log in to the network album on his computer, entered Zhao Bing's account number, and password 12345, and it was really successful!

The moment he saw the album, Hu Yifei's face was full of guilt, this should be his first real hacking behavior. Although he still used the artifact, his ideas and flaws were all found by himself. For a pseudo-expert like him, this is already quite remarkable.

After Hu Yifei's chicken moved, he quickly flipped up these photos, except for Liu Xiaofei and Liang Xiaole he saw yesterday, he found that there were many photo albums, and after opening them, they were other women, but the content of the photos was very congested, and at a glance, he knew that these photos were also taken from the camera.

"Damn, it's really super perverted!" Hu Yifei recalled Zhao Bing's image again, and felt that it was simply carved out according to the perverted mold.

Hu Yifei scolded Zhao Bing for being perverted in his heart, but his subordinates did not stop, and stuffed all these very yellow and violent photos in the album into his "Line Surname Algebra" folder.

When he flipped through a photo album, Hu Yifei suddenly felt that this woman was a little familiar, but after thinking about it carefully, it seemed that he had never seen her, it was really strange, where did this familiar feeling come from?

"No matter, save it first!" Hu Yifei continued to save, and when he saved a close-up of his face, he patted his head, damn, I remembered it, I seemed to have seen her in the employee directory of Dadao Company just now!

Hu Yifei found out the employee directory again, rummaged through more than a dozen of them, and found a similar, after a careful comparison, Hu Yifei is completely sure that the woman in this album is a copywriter of Dadao Technology.

"Damn, you kid can eat the grass next to the nest!"

Hu Yifei was very disdainful, and then compared the women in the remaining albums, and found that except for two that were not found, the others could be found in the employee directory of Dadao Company, all of them were very beautiful women, it seems that Zhao Bing has a very long history of engaging in this set.

"It seems that Lao Tzu is going to eliminate harm for the people!"

Hu Yifei smiled silverly, and quickly stuffed those photos into his hard drive, but he didn't delete the things in the album as planned, and even changed the password back to Zhao Bing.

He thought of a good way to kill Zhao Bing in one hand, but he still owed something short, so he couldn't startle the snake.
