Chapter Eighty-Seven: Hacker Marking

The next morning, Hu Yifei went to work, eating breakfast at the fritter shop at the school gate, and suddenly saw the word hacker appear in the "Dongyang Morning Post" on the newsstand next to him, so he went over and opened it to take a look, the title was "Well-known hacker peeps at female colleagues, experts say they may be sentenced!" 》

Hu Yifei paid a dollar and bought it to eat and watch, although a pseudonym was used in this report, and Dadao Technology was not mentioned, Hu Yifei could see at a glance that this was talking about Zhao Bing.

If the case is under investigation, the media will not dare to report it indiscriminately, it seems that the matter has reached a conclusion, Hu Yifei sighed, and said in his heart that Zhao Bing also deserved it, with a high salary and a good job, but he was not satisfied, but he thought of various ways to collect money, acting for the tiger, selling the Trojan virus to the number theft group, selling the strategy to carrots, and even his own company had to be pitted.

The most hateful thing is that he used his own technology to conduct shameless voyeurism, and after deceiving Liu Xiaofei and being rejected, he even arrogantly harassed and intimidated. Thinking of this, Hu Yifei itched his teeth, all the photos in the online album had been cleaned up by himself after he started it, but I don't know if Zhao Bing's kid still has a backup elsewhere.

Hu Yifei looked at the report and said that the police found a Trojan horse program in the private computers of Zhao Bing's female colleagues, and it had existed for a long time, plus the photos in the email, it was almost conclusive evidence. At the same time, the police also detected many viruses and Trojans in the internal network of Dadao Technology, which were all made by Zhao Bing.

The media has always only reported things that can catch the eyeballs, and only briefly mentioned Zhao Bing's kickbacks, saying that the police found that Zhao Bing purchased various network security equipment for Dadao Technology, most of which were inferior products that had not been formally tested and certified, and the police would conduct further investigations into the matter.

"Heaven is evil, but it is still alive; A man who has done iniquity shall not live. ”

Hu Yifei shook his head, rolled up the newspaper, and went to Weilan.

All the scans have been done, Hu Yifei has nothing to do today, and he has been sitting and reading the things written by Cobra since he came to the company, and a few security guards continue to do 3C on the side.

When it was almost time to eat at noon, the walkie-talkie placed on the table by the security guard suddenly shouted, "Bull head, bull head, I'm a druid, please retreat quickly, there are dangerous people moving in your direction!" Again, retreat quickly, there are dangerous people moving in your direction! over! ”

The four security guards stood up quickly, didn't even quit the game, just turned off the phone, and then grabbed the hat walkie-talkie and ran out, "Little brother, someone is coming, see you in the canteen later!" The four of them went out and lined up, looking like they were patrolling collectively, and left in disguise.

Hu Yifei muttered in his heart, damn, these guys are really unrighteous, so tell me who the dangerous person is and how dangerous it is, so let's decide if I want to hide too?

Before he could make a decision, as soon as the door of the Cyber Security Department opened, Xiaoqiang and his brother walked in, saw Hu Yifei, and said: "You kid is really good, I'm so busy here, you still find me trouble, you just tear me into two!" ”

Hu Yifei stood there and wondered, he didn't know what Xiaoqiang's brother meant, he didn't seem to have offended him!

Xiaoqiang's brother didn't explain, took out another page of A4 paper from his bag, and slapped it on the table in front of Hu Yifei, "You can also scan the IP on it." Remember, leave it to me at this time next month, and if you finish sweeping it in advance, you can sweep it again, and if it doesn't work once, twice! ”

Hu Yifei nodded and took it, and said in his heart, Lao Tzu, I will kill you, you simply said that I will be swept until this time next year.

"You're really my mother!" Xiaoqiang and his brother looked at Hu Yifei, "Can you just take it a little more leisurely, or can you divide these IPs into several batches and give them to me slowly?" More than 300 IPs, you finished sweeping in three days, and you saved yourself, so do you know how long it will take me to design security policies for these IPs one by one? Xiaoqiang's brother looked angry, "It's really going to be my life, I don't want to take a day off for two months!" ”

Hu Yifei was dumbfounded, it's also a sin to do your own work quickly, you can't do it yourself, can you blame Lao Tzu for being too efficient? Besides, when you handed it over to me, you didn't make it clear!

"What are you looking at, why don't you hurry up and scan it!" Xiao Qiang and his brother glared, walked to a desk, pulled out a document from a drawer, stuffed it into his bag, and left in a hurry.

Hu Yifei couldn't understand the network security department even more, Cobra said that he was very busy, Xiaoqiang and his brother also said that they were very busy, but no one came to work overtime, and he came over that day, and he was an idler sitting in a room, and he didn't know where they were busy.

At lunchtime, Hu Yifei asked the security guard again, and got more answers, in addition to waste and brother-in-law, there are all kinds of theories, but none of them are reliable, and some people even say that the network security department looks like a department, but in fact it is two departments, and there are only four people in the real network security department, just cobra and three subordinates, and the rest are people from another department, but what department it is, but it is impossible to say.

Hu Yifei had a headache, and after eating, he continued to go back to read the information.

Back to school in the evening, just on QQ, the tarantula appeared, he has been busy participating in the wolf summit recently, rarely on this QQ that he is not used to, today the wolf summit is finally over, he has the opportunity to ask Hu Yifei about his recent learning progress.

Hu Yifei reported his learning, and the tarantula asked two random questions in the previous information, and Hu Yifei's answers were very accurate.

The tarantula sent a smiling face and praised: "You are very talented, and you will be an excellent hunter in the future!" ”

Hu Yifei had a bitter face, he had studied as a hunter for a week, didn't he still find a way to track down the sugar-fried chestnuts, he had the talent to use a ball, and 10 million was the most real.

"But your teacher is the most powerful, his articles are commanding and majestic, and they have given me a lot of inspiration. He is a great character, and if you learn from him, you will become a great character too! The tarantula sent another message, denying his previous statement, and it was difficult for him to understand why Hu Yifei had such a good teacher, why he followed him to learn hunting.

"Thank you!" Hu Yifei thanked his non-existent "teacher", "I will work hard!" Thinking of the part he saw today, Hu Yifei asked: "I saw the information today, saying that every excellent programmer will leave his own mark in his own program, how do you think about this?" I looked at a code and didn't find any clues about the authorship! ”

"Most of the marks are very subtle, and only a few people will leave obvious marks!" Tarantula explained to Hu Yifei, "Some will use the remarks function of the code to leave a mark, which can be directly the author's name, or a poem, a character, or even a number, which are obvious." But some are not, and you have to identify the author based on a code that represents a surname, a module, or the overall writing style of the code, which is a customary surname marker. ”

Hu Yifei scratched his head, when he saw this mark today, he remembered the email virus code that he handed over to him before the sugar fried chestnuts, but he couldn't find anything like the name or font size in it. Now listening to the explanation of the tarantula, it must be a customary surname mark, but where do you go to learn about the habit of fried chestnuts in sugar?

The tarantula didn't know what Hu Yifei was thinking, and continued: "It's the same with hackers, some hackers are very confident, and every time they capture a target, they will leave obvious marks to claim that they did something, such as a special piece of data, a file, a picture, or some kind of fixed work. And some hackers do not stay, the identity of this hacker needs to be confirmed from some habits, the simplest, is to determine from the attack method, such as what kind of springboard to build, what tools to use to scan, and what vulnerabilities to use to invade, as well as specific intrusion steps and post-invasion behavior, and finally the performance of cleaning up the Zhi, combined with the field that hackers specialize in, you can determine which hacker did it, because no one can do all these links exactly the same as another hacker. ”

"Even then, you can't tell the identities of all the hackers, right?" Hu Yifei asked.

"Of course not, it takes a lot of collection, analysis, and accumulation. My teacher, the hacker identification database in his hand is by far the most comprehensive and highest-level one, and he can analyze the identities of more than 3,000 top hackers in the world! ”

Hu Yifei's eyes lit up, "Then can you use this library?" ”

"I can't usually reach it, but I can only reach it when I go to help the teacher do the test!"

"Then the next time you go to the test, can you help me look up some information?" Hu Yifei asked again.

"It's hard to say this ......, and you don't necessarily have access to that library if you do experiments!"

Hu Yifei gritted his teeth, picked out two hard drive notes and sent them to the tarantula, "Help, it's actually very simple, it's to help me determine the author of a piece of code!" ”

When the tarantula saw the note, he was relieved, it was really soft on people, and it was the shortest time to eat people, and said, "Okay, I will inform you before I go to the experiment next time!" ”

Hu Yifei thanked him, consulted the tarantula with some questions about his studies, and went offline to rest.

After being so busy for a week, it's the weekend again, Hu Yifei has a headache, twenty or thirty IPs let him sweep for a month, it's really embarrassing for himself, on average, three or four a day, but it's really going to be a bad day, when will he be able to get in touch with the real project.

When they entered the door, the security guards were playing 3C again, and they were being suppressed by the other party at the door of the house, and they couldn't rush out, so anxious that they yelled at each other.

Hu Yifei was so noisy by the security guards that he rummaged through the office, found a pair of headphones, turned on the music, and then rummaged through the server to see if there were any new articles coming out of COBRA this week.

As a result, I saw a title: "Thoughts on the Zhao Bing Incident", Hu Yifei was excited, and quickly clicked on it to see it.
