Liu Xiao summed up all the methods used in yesterday's attack, and it was like looking for a needle in a haystack to find relevant clues from the vast amount of data, but it was relatively easier to find the data of his previous detection of relevant vulnerabilities according to the attack methods.

After summing it up, Liu Xiao took out the data analysis tool and began to search for the data that detected these vulnerabilities in the data records within a week. The data is very large, and it takes a while to search, Liu Xiao sat there and waited for the search results, and began to figure out the words of Treading Snow without a Trace, he said that even if he found it, it would be impossible to catch him, because it was not a person, but yesterday's attack, I didn't see that the other party was a group of people. I originally thought so, but today's analysis report proves that it was a person who attacked the server of the Soft Alliance yesterday, and it is impossible to lie without a trace, so where are the accomplices?

"Strange, what are these people going to do in China?" Liu Xiao was also suspicious of the purpose of infiltrating China at this time.

"When" prompted, Liu Xiao came back to his senses, looked at the screen, the analysis results had come out, he opened the results and looked, sure enough, as he guessed, the server had been scanned and probed many times before it was attacked, and the data that detected those attacked vulnerabilities had a total of three times before and after, all from the same IP.

Liu Xiao glanced at the IP, and was a little surprised, this IP actually came from Haicheng, and Liu Xiao had already memorized all the IP segments of Haicheng.

"Is it in Haicheng?" Liu Xiao asked himself strangely, and then shook his head, there is this possibility, but I can't be sure, this IP is just a springboard or proxy used, and no master will be stupid enough to use his real IP to scan the object to be attacked.

Liu Xiao wrote down this IP, and then returned to his office, he had to find some tools to take advantage of, the other party was not a rookie, he had to be prepared for both, in case this IP was really the real address of the other party, he recklessly ran to probe and was discovered by the other party, then it would be a surprise.

Sitting in front of the computer in the office, Liu Xiao found that his mobile phone had fallen on the table, so he picked it up and took a look, after such a while, there were more than ten missed calls, and after checking again, he found that all of them were from Huang Xing. Liu Xiao was very puzzled, didn't he just talk to him before, what was so anxious, so he dialed back, and a few seconds later, a service tone sounded: "I'm sorry, the phone you dialed has been turned off, please dial again later!"

Liu Xiao scratched his head with the phone, why did he turn off the phone?"Forget it!" Liu Xiao sighed, if there was really an emergency, then Huang Xing would call again.

Leaving the phone aside, Liu Xiao was busy in front of the computer, he had to determine a foolproof plan, and he must dig out the real address.

Put all the selected tools in the USB flash drive, Liu Xiao went to the laboratory, the company's computers are in the local area network, only the laboratory computer has an independent public network IP, which is convenient to do things!

After turning on the phone, Liu Xiao sent a detection message to the IP, and a few seconds later, the prompt message returned, indicating that the IP was not online at this time, Liu Xiao was numb at this time, he was ready, the object was not online, what should I do, you just want to fight, then you have to have an opponent!

There was really no way, Liu Xiao had to call up his IP database first, and check the specific information of this IP first, who knew that as soon as he entered it, he found something more unlucky, this IP is the same as those IPs used in the attack, they are all non-fixed IPs, that is to say, even if this IP is online, it may not be the machine used in the previous detection.

If you want to know who was using this IP at that time, you can only go to Telecom to check, but Telecom will not tell you, this is their customer secret, unless the Public Security Bureau files a case for investigation, the police have the right to ask Telecom to provide this information, Liu Xiaoyi can't prove that the IP attacked the soft alliance, and the second is not the police, why did Telecom provide him with these information?

But this is not entirely a bad thing, at least Liu Xiao can now be 100% sure that the person who used this IP to probe the server of the soft alliance is absolutely undoubted. Some hackers are accustomed to using those machines with fixed IPs as their springboard, and some like to use non-fixed IPs as their springboard, and it is undoubtedly the latter, whether it is detection or attack, he uses these non-fixed IPs to better hide himself.

"What now?" Liu Xiao ran out of ideas, among the people he knew, if there were only Huang Xing and Ge Yunsheng who could have the right to get these materials. But Ge Yunsheng only has a one-sided relationship with himself, and he probably won't help himself with this, not to mention that he is only responsible for network security in telecommunications, and he may not have the right to access these materials. As for Huang Xing, Liu Xiao is a little hesitant now, not knowing whether to contact him or not, since he can know that he revealed his whereabouts in Fengming to the network supervisor, it means that the network supervisor has no secrets to speak of, and he will notify Huang Xing now, and if he doesn't have good news, he will leak it again.

Thinking of this, Liu Xiao stood up and went to his office again, the other party was not online, and the tools he had prepared would not be used, so he had to go back and choose the tools again and implement the second set of plans.

Back in the office, Liu Xiao found that he had forgotten his mobile phone on the table again, picked it up and thought about it for a while, he dialed Huang Xing again, reminding him that it was still necessary, but who knew that the phone was still the service tone that the other party turned off.

"It seems that God won't let me tell you!" Liu Xiao sighed, and then he remembered to put his phone in his pocket before sitting in front of the computer.

In fact, the second plan is very simple, that is, to find out the use of that IP from telecom through illegal means, Liu Xiao has a way, but he is very hesitant and can't make up his mind whether to do it. After all, for so many years, he has never invaded illegally because of his own interests, and the last time he invaded telecommunications, although it was also an illegal entry, in Liu Xiao's view, it was purely a necessary infiltration detection done by hackers in order to pursue endless security.

After scratching his ears for a long time, Liu Xiao made up his mind, gritted his teeth, copied two more tools into the USB flash drive, and then went to the laboratory, he had to do this thing, whether he was illegal or not, it was an illegal thing in itself, and he made it illegal by illegality, and from the perspective of the ultimate goal, he was not wrong.

The database of telecommunications is impossible to view externally, even if it is inside telecommunications, it must also have permissions, Liu Xiao has carefully studied it before, although the internal protection of telecommunications is good, but there are also opportunities to take advantage of.

Liu Xiao's two tools, one is to use the error of the telecom online business hall system to directly link into the telecom, and the other tool is used to create a fake database account. This is a new hacking method, as far as Liu Xiao knows, there are very few people in the circle who can use this technology, through this tool, Liu Xiao can create a virtual account to access the database, but this account is very strange, just like the thousands of stand-ins blown out by Monkey King, no matter how many stand-ins, there is not one more Sun Dasheng in this world.

There will not be an additional permission account in the database of Telecom, and it will not be possible to find this virtual account, it is like air, any operation on the database will not be recorded, but it can cheat all the permission checks through Sun Dasheng's appearance and get the information it needs.

After Liu Xiao connected to the internal network of China Telecom, he obtained a list of authorized accounts in the database, and the permissions of these accounts are different, and different accounts can only access different materials within the specified authority. Liu Xiao didn't have the time to study these permission settings now, so he simply chose the account with the highest virtual authority, which can access all the information.

Liu Xiao ran the second tool, entered the name of the account he wanted to virtualize, and after clicking the link, he successfully entered the database of Telecom.

Seeing that there is no abnormality, Liu Xiao quickly has to find the IP record of the user's Internet access, Liu Xiao enters the IP he remembers, and he wants to query the record of the IP being assigned within a week. The results displayed greatly surprised Liu Xiao, and during the time period when the IP scan probed the server of the soft alliance, this IP was assigned to the same telecom user. Liu Xiao wondered in his heart, how could it be so coincidental, a user was assigned to the same account three times in a row, this probability is simply minimal, for insurance, Liu Xiao also specifically checked the user's Internet records, if the user is assigned to this IP, always keep the Internet online, it is also possible to occupy this IP for a long time, but the result of the query is not like this, this user is online for less than two hours a day, and as long as it is online, it must be assigned to this IP.

Liu Xiao wrote down the user's account number, and then went to check the user's registration information, the registration data showed that the user was a non-fixed IP user, and an address was randomly assigned from the IP pool of the telecom every time he went online.

Liu Xiao now has a deep suspicion of this user, in this case, someone must have tampered with the data in the background of Telecom, binding this user to this IP address, but the person who modified it will definitely not be a person from Telecom, what reason does the person of Telecom have to step on the server of SoftAlliance.

Now only from this user to check, or just wait for this IP to go online, Liu Xiao opened the detailed registration information of this user, and then found a pen and paper and recorded them one by one.

After doing this, Liu Xiao was ready to retreat, and as soon as he cleaned up the tail that he might have left behind, he heard a sudden "drip" of the tool. Liu Xiao was still a little puzzled, could it be that he failed to wipe the footprints just now? If the operation is not done properly, or the authority is not enough, it will cause the operation of erasing the footprints to fail, this is not an impossible thing, thinking of this, Liu Xiao is ready to clean up the tail again, who knows that the tool "drips" at this time.

"That's not right!" Liu Xiao scratched his head, "I haven't done anything yet!", he finally realized that this may not be a hint of a failed operation, but something else happened.

Liu Xiao quickly typed in a command to check the status, and after a while, the result was displayed, and Liu Xiao was directly frightened. On the list of permission accounts in the database, the top ones are actually three identical accounts, and this account is the virtual object of Liu Xiao.

In fact, there is still a little difference, in order to distinguish between real and virtual accounts, Liu Xiao's tool will display a "*" sign behind the virtual account, and now the tool shows two accounts with an asterisk, that is to say, at this time, there is another person who has come in with this account virtually, this is really a fucking coincidence, and someone plucked a hair from Sun Monkey.

Liu Xiao was in a cold sweat at that time, and he even forgot what to do, if he had changed normally, he would have run away, but today he sat there stupidly, staring at the three identical accounts.

The person who came in with the same means as Liu Xiao must have also discovered this anomaly, he seemed to be stupid, he didn't operate a single operation after coming in, and he probably stared at the screen on the other end of the computer in a cold sweat.

If the two can meet, it is estimated that this meeting should be like a duel between masters in martial arts films, no one will make a move, just poke there, put a good pose, and then crush each other to death with the aura of the king exuding from the whole body, so the idea of killing, probably that's it.

It's a pity that the network is not air, and it can't convert this overlord gas into electronic data and send it to the past, let alone convert electronic data into the king's gas, and then kill the person on the other side of the computer with his mind. The network is the network, and it has its own "aura" transmission mode.

With a "tick tick", Liu Xiao found that a new user appeared on the list of permission accounts, in English, which translates to "Who are you?"

"Hacker!" Liu Xiao seemed to have suddenly lost his ability to think at this time, and such a word popped up in his head, and he changed the account to "hacker".

"What are you doing?" the other person changed the account again.

"It's the same as you!" Liu Xiao revised again.

The two were communicating in this strange way.

"You're skilled!"

"Thanks for the compliment!"

"Don't you ask who I am?"

"You're not going to tell me!"

"I haven't had this before!"

"It's the first time I've done it!"

"Make a friend?"

"Maybe in the future!" The other party took the initiative to get closer, Liu Xiao had to be more and more careful, and he didn't dare to leave the slightest trace between his words.

The other party looked at Liu Xiao a little coldly, and he couldn't find a conversation for a while, and the two fell into the silence they had at the beginning again.

After a long time, Liu Xiao couldn't sit still, the database had an extra permission account out of thin air, and the people in telecom could find this anomaly at any time, and if they continued to consume it with the other party, no one would be able to leave at that time!

"Is there anything else?" Liu Xiao changed the name of the account again.

"Probably not!"

"This place is not good for long!"

"Will we see each other again?"

"Maybe!"

The other party was silent for a while, and then modified the account again, "There will be a period later, I'll wipe the footprints!"

"Thank you, there will be a date later!" Liu Xiao finished changing this sentence, without saying a word, he quickly evacuated from the telecom network, in fact, when he revised the last sentence, he had already erased his footprints, and now he didn't know who the other party was, so he didn't dare to leave the footprints to the other party, as for him to say "thank you", it was to remind the other party to clear the username that was changed around.

Turn off all the links to telecommunications, Liu Xiao let out a long breath, he was too nervous just now, he didn't even dare to breathe, those who can use this technology to enter telecommunications are definitely not ordinary masters, today is really very lucky, the other party doesn't seem to have any malicious intentions, otherwise it is difficult to say whether he can get out of the way today.

Liu Xiao wiped the cold sweat off his face, and then picked up the information of the telecom user he had just recorded and looked at it, he was going to check the real information of this user, of course, this also requires a little illegal means, because no institution is obliged to provide these private information to himself!

"God forbid, don't have any more accidents this time!" Liu Xiao first clasped his hands together, and then drew a cross on his chest, and he didn't know which country he was praying to.

Liu Xiao shook the mouse, ready to start the war again, as soon as his hand touched the keyboard, there was a sudden very violent "bang" twice, "Liu Xiao, you come out for me!", and the door of the laboratory was also buzzed.

Liu Xiao was overly nervous and reflexively jumped up from the chair, but after jumping up, he calmed down, because he had already heard that the owner of this voice was Huang Xing!

"Liu Xiao, you come out for me!" came Huang Xing's voice outside the door again.

"It's coming, it's coming!" Liu Xiao cleaned up the computer slightly, turned around and hurriedly opened the door. He also took out his mobile phone and looked at it, there was no missed call on it, and he couldn't help but wonder, what the hell is going on with this yellow star, when he contacted him in the morning, he was still in Fengming, how could he arrive in Haicheng in a blink of an eye, even if there is a big thing, there is no need to be in such a hurry!

"Damn, it can't be a big deal!" Liu Xiao couldn't help but feel nervous in his heart, he was really lucky today, he could meet people in the same way when he invaded telecommunications, and nothing could happen!
