Chapter 215 Specific Attack

As soon as Hu Yifei said this, even Cobra put down the things in his hand and walked over, "Z language code?"

"Yes!" Hu Yifei pointed to the prompt on the screen. His tool had intercepted some of the code. "The code is encrypted, but it will not be wrong. I am sure of the z language!"

"No wonder!" Captain Li slapped the table, "I said why can't we check for any abnormalities!" All the detection tools of the network monitor cannot detect malicious code written in z language. The z language statements are very concise, and the malicious code written is completely different. It is definitely not possible to rely on previous feature code detection technology.

"Someone used the z language so soon?" Cobra was also surprised, saying: "Hackers always use technology to attack technology faster. This sentence is true!"

The mayor didn't understand what Z language was. He watched the three people discuss and discuss it, but he didn't understand a single sentence, and said, "Is the problem really lies in the Organization Department's website?"

"It's basically true!" Hu Yifei nodded, "but we have to analyze the functions of these codes specifically to see if they can be linked to previous espionage. If the two match, it can prove that the source of the espionage comes from the website."

"How long will it take for the analysis result?" asked the mayor.

"It may take several hours!" Hu Yifei said, and then looked at Captain Li after he finished.

Captain Li gritted his teeth, "I will call a few data analysis experts to cooperate with you, and come up with specific results within two hours, how about it?"

"Leave the data analysis to me!" Cobra smiled, "I am an expert in this field!"

Captain Li slapped his forehead, "Look at me, I forgot you all this urgent, so I'll trouble Mr. Hui. Just say whatever cooperation you need, let's try to draw a conclusion as soon as possible!"

The mayor was not in a hurry to get off work and ordered his secretary: "You go and cancel my evening banquet. I'll wait for the result to come out!" After that, the computer of the Mipiao Astronomy Supervision Commission has deployed a virtual environment, which is specifically used to analyze the behavior of viruses and Trojans after entering the system. Unfortunately, their monitoring software is all blind and deaf this time, and they have no idea about the new invasion method. Hu Yifei had to redeploy the virtual environment and install his monitoring tools in.

After turning on the monitoring, Hu Yifei reopened the website of the Provincial Party Committee Organization Department in a virtual environment, and then stared at the monitoring records and saw that the displayed data began to refresh quickly. After a while, the data renovation speed significantly accelerated, but this rate began to stabilize.

"It's OK!" Cobra spoke out and reminded that he was very experienced in data analysis, "You can stop!"

"Okay!" Hu Yifei nodded, but did not rush to turn off the monitoring. Instead, he first turned off the organizational department website in the virtual environment. Then he saw that the surveillance data was refurbished instantly. After waiting for more than ten seconds, Hu Yifei then turned off the monitoring software and began to extract data.

"Everyone, let's take action separately!" Captain Li divided the work for everyone. "Xiao Hu was responsible for studying how these codes came in. Mr. Hui just looked at what these codes did when they came in!"

Cobra is indeed an expert in analyzing data. He is responsible for analyzing most of the data. He can draw a conclusion first compared to Hu Yifei. "There are three codes in total. The first code is very small. It sneaks into the computer through the browser and then downloads the second code back. After the second code reaches the computer, it first clears the first code, and then downloads the third code back. The third code enters the computer and immediately establishes a disguised SSL connection with an IP, and then starts uploading and transferring the things on the computer. It does not scan keywords and randomly crawls files for uploading. It looks like a completely normal connection, so it is difficult for us to find out."

"Then why didn't we find these two codes on the computer?" Captain Li asked.

"The code is written in z language, and after encryption, it is difficult for us to detect it. The attacker is very confident. He is sure that he can repeat it, so he did not open the back door on the computer, nor did he let the code reside in the computer. When we closed the website of the organization department, the ssl connection was immediately disconnected. At this time, the second code started running again. It deleted the third code, then cleaned the log, and finally deleted itself, and there was no trace left on the computer!"

"This is not an ordinary hacker!" Captain Li made a judgment immediately. "It is absolutely a very professional hacker to be able to do such a complex operation process smoothly, and to be disguised in every link, and the anti-detection ability is so strong that it is so meticulously crafted. This is definitely a very professional hacker!"

The mayor stood up and said, "Captain Li, can you confirm it?"

Captain Li nodded, "It can be confirmed that the data analysis is exactly the same as the lost files of our city government computer. It can be confirmed that the hacker launched the attack through the website of the Provincial Party Committee Organization Department!"

"Collection of detailed written materials immediately!" After the mayor gave the order, he came to the desk step by step, picked up the phone and dialed a number, "Is Secretary Guoqiang? I am Sancai. I have a very important thing to report to you. The matter is very serious!", "Okay, I understand, I'll come here now!"

After throwing down the phone, the mayor said to Captain Li: "Hurry up, I can't wait for you to prepare the materials. You can go with me now and give a verbal report to Secretary Guoqiang!"

Captain Li stood at attention with a "snap", "Yes!" After that, he said to Hu Yifei and Cobra again: "I'll both of you here!"

"Thank you for your hard work, now the matter is urgent. I want to report this to my superiors! When I come back, I must thank you both!" The mayor did not delay and hurried out. After that, he ordered his secretary to stay and take care of him.

"Xiao Hu, how are your analysis?" Cobra came to Hu Yifei at this time.

Hu Yifei was sweating all over his head and smiled awkwardly, "This data analysis is really not my strength, it will be fine soon. It has been confirmed that it is a vulnerability on IE. I am analyzing the specific information of the vulnerability!"

Cobra patted Hu Yifei on the shoulder and laughed, "Don't panic, calm down, the analysis will be faster. I'll extract the signature codes of those three malicious programs!" After that, he returned to his computer and started to extract the malicious code. Captain Li came back later and would definitely use this one.

Dongyang is a provincial capital city. The mayor will not waste much time when reporting. Hu Yifei analyzed the loophole information and came up with a temporary compensation plan. Even if the matter is finished, the mayor's Seppiao Astronomy Supervisor has a meal.

As soon as everyone picked up the chopsticks, Captain Li came back, and there were people from Guoan behind him.

"Thank you all for your hard work!" Captain Li walked away and sweated his forehead. He took off his hat when he entered the door. "The province attaches great importance to this incident and believes that this may be a carefully planned act of stealing secrets. He has ordered our online surveillance to cooperate with the National Security Operation. First, we will quickly launch an investigation across the province to find out how much the losses are; second, we will track the hackers who steal secrets and must seize this black hand!"

Hu Yifei swallowed the vegetables in his mouth, thinking that he should be nothing he had done about it, so he said, "I have figured out the method of entering the code and have come up with a temporary response plan and put it on your computer!"

"Thank you for your hard work!" Captain Li didn't care about being polite and directed several other network monitoring technicians in the house. "You stay and hand over the directory of the lost documents in the city government to the comrades of Guoan!" After saying that, he was about to go out. "I have to go to the bureau to arrange it. I must find out the situation of several districts and counties tonight!"

"You go!" cobra nodded, "I'm here!"

"Then can I go back?" Hu Yifei asked Cobra. He couldn't even eat when he walked around the house with so many big blocks. "The matter has been figured out, and I can't help with the next thing!"

"Okay, I'll notify you if you have anything to do!" Cobra didn't try to keep it, threw down his chopsticks, and directed the technicians in the Internet Supervision to use the feature code he just extracted to conduct a comprehensive scan of government websites across the province and the city to see what other websites were hit.

After leaving the municipal government website, the boss turned around unhappily, "We worked so hard that we made a meal, but we hadn't eaten it yet, really!"

"Well, just treat it as a helping Captain Li. We usually take jobs from the Internet prison!" Hu Yifei looked around and said, "Let's go, find a place to eat first!"

The two found a restaurant, had enough food and drinks, and then returned to the company. Hu Yifei remembered what happened tonight and couldn't sleep, so he posted another announcement on the website, titled: "The specific habits of specific professional groups may be exploited by hackers!"

In this incident, the hacker was just waiting for the situation. He just got a website and achieved the greatest results at the lowest price. Instead, the attack was targeted and covered. After all, the hacker took advantage of the specific habits of this specific group. If the information was more informed, the hacker could even determine his attack target based on different time periods. For example, at 8:30, he would definitely be the mayor, which was extremely accurate!

By analogy, there are many professions that have certain habits. Hackers can easily obtain enough targeted information when they stand at a commanding height.

After sleeping until midnight, the company's doorbell sounded loudly. Hu Yifei got up and opened the door, and Captain Li stood outside the door.

"It's serious!" Captain Li looked serious and tired, and did not come in. He just whispered: "All across the country, many websites that have been dealt with by others, involving multiple fields of government, technology, and military..."

Hu Yifei was immediately scared to death. Damn, isn’t this a replica of the secret escort incident mentioned in the United States before, and it has a larger scope.

"We really need the kind of tool you have in your hands that can detect malicious codes in unknown z language!" Captain Li swallowed, probably not drinking water all night. "You should act now and improve that tool. We will have it tomorrow. It was ordered by the department from your Figo software!"
