Hu Yifei didn't go to class for the third day in a row. When he got up in the morning, he started to tinker with the server of Dadao Technology Company. This is a intensive job. Hu Yifei basically followed the steps written on the spider materials. He had read it several times before, but when he really used it, he found that he forgot all of it. He still had to follow the instructions that Piaotianwenwen and entered the intranet. He could see the machines inside Dadao Technology Company. He just happened to be working yet. He searched for several intranet computers, which were very important machines. These machines usually run 24 hours a day, and they will not shut down except for routine maintenance.

The material of the wolf spider is written. There are many ways to invade the intranet machines. Eavesdropping on account passwords is the most reliable, and studding is the most effective in poisoning. The method of remote login is not possible, because personal operating systems generally do not allow multiple users to log in at the same time.

Hu Yifei doesn't know how to poison the stallion. He only needs to use the artifact when logging in remotely. The restrictions mentioned by the wolf spider do not apply to the artifact. He used to monitor Duan Yu Xiaoli's computer himself, and they also installed a personal operating system. In front of the artifact, there is no restriction on multiple users login.

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

After thinking about the process in my mind, Hu Yifei was about to start. He first used the artifact to enter the gateway server of the Avenue, then downloaded the artifact, linked their intranet computers, and finally smashed the artifact and cleaned the logs.

"Not right!"

Hu Yifei was about to link up, but he remembered a very important thing. Once the artifact enters the working mode, he will not exit. He can't turn off the computer at that time! If there are hundreds of computers in the intranet of Yidao Technology and are not lucky, wouldn't he have to turn off all the computers to find Zhao Bing's computer?

"Day, silly!" Hu Yifei grabbed his head and planned the action that he had been doing all night, but he failed before he could take action. Only then did he realize that having a magic weapon was even worse than those little hackers with solid basic skills. He had a magic weapon that could handle everything, but he could not handle the intranet machine alone, unless he was in the other party's intranet! Looking back, the method provided by the wolf spider was the most reliable at that time, but unfortunately he believed in the magic weapon too much, so he wasted so much time.

Hu Yifei doesn't want to continue to tear him down with Zhao Bing now. Even if he uses the tarantula method, he may not be able to succeed in a while. If he uses it impurely and exposes the filling, it will be even more troublesome.

After thinking for a long time, Hu Yifei had the idea of ​​the intranet computers he had searched for. He decided to turn off the computer once to see if he could get any information from the other party's computer. Finally, he chose a computer named xx.

Using a magic tool to connect to the intranet computer on the other party's gateway server, there is also a little bit of a second-layer springboard. When Hu Yifei thought about this, he saw the picture of the xx computer.

Without saying a word, he went directly to the working mode. Hu Yifei flipped through the computer, hoping to find some clues. He searched through all the disks and finally found only a list of employees. This was a bit useful to Hu Yifei. The rest were all information and reports from Dadao Technology Company. For Hu Yifei's purpose, these had no value in utilization.

Hu Yifei flipped through it and found Zhao Bing's information in the employee directory, including photos, contact information, and even Zhao Bing's home address. Hu Yifei was overjoyed and was about to write down all of them. Then he thought, he was not coming to the door to cut people, so what's the use of memorizing them?

Unable to think of any good idea, Hu Yifei packed all the employees' directories and sent them back to his mailbox.

After searching again, there was no gain. Hu Yifei secretly said that he was unlucky, so he cleaned the logs, turned off the xx computer, and then smashed the artifact on the gateway server. After cleaning the logs, he evacuated the Dadao Technology Company.

Hu Yifei searched through which employee lists were read on his computer again, but he still had no idea, so he had to give up temporarily and instead think about how to break through Zhao Bing's online album, which contained photos of his woman, which must be deleted.

Brutal cracking passwords is too time-consuming, and even if you get one, it is not very useful, because Hu Yifei had already discovered that Zhao Bing is very treacherous and uses three passwords on the domain name management website, email, and online photo album. He counted carefully and the lengths of the three passwords are different.

"Then use your old skills!"

Hu Yifei used a magic tool to connect to the server of the network album. With the experience of getting carrots, he found the database address in the code with familiarity. Now he thinks that the book "Website Architecture" Piaotian Silk Station Architecture said that such password storage method is relatively safe. The reason why it is safe is that these encryption algorithms cannot be decrypted in reverse. In other words, when you see these encrypted characters, you cannot decipher the original real password. And no matter how long the password is, all of them are 18 bits after encryption. You cannot know how long the original password is. Even if it is brute force cracking, it will undoubtedly increase the difficulty.

When a user logs in, he or she just needs to enter a normal password. After the password is submitted to the website, it will be encrypted first and then compared with the password saved in the database. If it matches, the login will be successful. If it doesn’t match, the login will be failed.

Thinking of the last report meeting of Cobra, he changed the password saved by the administrator in the database. But if he changed Zhao Bing's password to 12345 directly in the data, it would definitely not work, because after 12345 is encrypted, it will not be 12345, and the comparison will definitely not be successful.

Hu Yifei had no idea about password encryption at all, but he was very smart and immediately found something that could be used in this process: this encryption method must be fixed in one direction. For a fixed password, the 18-bit characters formed after encryption must also be fixed, otherwise there is no way to compare.

In other words, if you can know in advance what kind of characters 12345 is encrypted, and then use this character to replace the characters that already exist in the database, then enter the password 12345 and you will definitely be able to compare successfully and log in successfully.

Hu Yifei was happy about his ideas, and he flipped through the website code again. Soon, he figured out what the encryption algorithm was. It is a relatively popular general algorithm called md5 encryption algorithm. This is clearly explained in the website code.

"md5 encryption", the keyword Hu Yifei was put into search engines, and many results appeared, including the md5 encryptor, which can enter the password and display the encrypted characters. Hu Yifei downloaded one, entered 12345, and obtained an 18-bit character, which is very similar to the dense characters in the database.

Hu Yifei re-entered the other party's database. 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 exited the database, started logging in to the online album on his computer, entered Zhao Bing's account and password 12345, and it was really successful!

The moment he saw the album, Hu Yifei's face was full of bull's face. This should be his first real hacking. Although he still used the magical artifact, his ideas and flaws were all found by himself. For him, a pseudo-insider, this was already amazing.

After Hu Yifei moved, he quickly flipped out these photos. In addition to Liu Xiaofei and Liang Xiaole who saw yesterday, he found that there were many albums. After opening them, there were other women, but the content of the photos was very congested. You can tell at a glance that these photos were also taken off the camera.

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

Hu Yifei cursed Zhao Bing in his heart, but he kept silly and stuffed all the pornographic and violent photos in the album into his "linear algebra" folder.

When I flipped through a photo album, Hu Yifei suddenly felt that the woman looked familiar, but when I thought about it carefully, it seemed that she had never seen her before. It was really strange. Where did this familiar feeling come from?

"Don't worry, save it first!" Hu Yifei continued to save it. When he saved a close-up of his face, he slapped his forehead. Damn, I remembered that he seemed to have seen her in the employee list of Dadao Company just now!

Hu Yifei found out the employee list again, searched through more than a dozen, and found a seemingly. After careful comparison, Hu Yifei was completely sure that the woman in this album was a copywriter of Dadao Technology.

"Damn it, you guys can eat the grass by your side!"

Hu Yifei was very despised and compared the remaining women in the albums. He found that except for two who were not found, the rest can be found in the employee list of Dadao Company. They are all very beautiful women. It seems that Zhao Bing has a lot of history to do this.

"It seems that I want to eliminate the harm for the people!"

Hu Yifei smiled lewdly and quickly stuffed all the photos into his hard drive, but did not delete the items in the album as planned, and even changed the password to Zhao Bing.
Chapter completed!
