Chapter 659: Anti-Stalking
Through the review of the log files, Xiao Yuan found several problems.
First of all, Xiao Yuan found that when he was talking to the agent just now, the agent sent every word he said through the network, and then every word he said was transmitted from the network, but in fact, an agent like Ning Lan did not need to use the network when talking to people.
Secondly, just when the agent and Xiao Yuan were chatting nonsense just now, some files on the computer were partially stolen by this so-called agent, fortunately, there was no sensitive data on the computer, and the data and files stolen were irrelevant, but such an obvious operation, Xiao Yuan did not find it, which made him feel that his face was a little unbearable, stealing things from his own computer, he couldn't remember the last time this kind of thing happened.
From these two points, Xiao Yuan can basically judge that this so-called intelligent program is very likely not to be a real intelligent program, but a person who hacked into his own computer, and then pretended to be an intelligent program, but the purpose was his computer.
"Damn, there's something like that." Xiao Yuan cursed secretly after deciding that the agent just now was a Li ghost based on the log file, his face became ugly, but his mind began to think about who was hacking into his computer.
This person is first of all a master, his own configuration of the computer, even if there is no network firewall installed, is by no means ordinary people say to come in, moreover, this person must know a lot about the previous agent, otherwise he will not imitate the agent's way of speaking vividly, even he has been deceived in the past, third, this person has a plan for himself, or thinks that he is hiding some secrets, and wants to come to his computer to find ......
Xiao Yuan listed some conditions in his mind, so the scope of the target was greatly narrowed, and the people who had the ability to do this within this range, or in other words, the people who could command the ability to do this thing were what he did not want to see.
"Well, I hope I'm wrong, and the agent just now is really just an agent." Xiao Yuan sighed lightly, the so-called coming and not being rude, although he didn't want to face it in his heart, he still decided to track down his stolen documents and data to see where the data went.
The difficulty of anti-tracking is greater than that of intrusion, this is a common sense, because in addition to technology, anti-tracking also requires anti-tracking people to have very strong analytical ability, and to be patient, experience is also crucial, of course, Xiao Yuan also has a very good anti-tracking tool in his hand - the anti-tracking software written by his old friend Snake Tooth, although the version he got can only be applied to the Windows system, but it provides the standard interface of POSIX, so Xiao Yuan wrote a bridge specifically for this software before, This allows it to work on a Unix system or UNIX-like system based on the POSIX interface via a bridge.
Fortunately, Xiao Yuan had a computer running Windows in his hand, he opened the notebook, downloaded the snake's anti-tracking software spyadre and the bridge from Xuan Ni's private space, and then disconnected the laptop from the laptop, connected the laptop running Windows with a network cable to the notebook running the Feonix system, and then configured the bridge between the Windows side and the Feonix side first.
After making preparations, Xiao Yuan ran SPYADRE under Windows, and the software found the Windows terminal of the bridge by itself according to Xiao Yuan's configuration, and connected to the Feonix system through this terminal.
Xiao Yuan transmitted the sub-tracking information to Spyadre through the feonix terminal of the bridge, and started its anti-tracking function, and the next time, it was automatically run by this software, if the other party did not have a special anti-tracking means like his ring logic lock, it would not be able to escape the anti-tracking of this software, but Xiao Yuan believed that there are really not many people in this world who have such a level of means as ring logic locks.
After the software was running, Xiao Yuan turned his head to look at Ning Lan's movements, but found that there was information coming out.
"Big brother, I figured out what that module does."
Xiao Yuan once again shifted his attention to the notebook that Rubin gave him, and asked through the message system, "Tell me, what is that module for?" ”
"There are two other programmable modules on this computer, one of which is integrated in the south bridge chip of this computer, and the other chip is also encapsulated in the sound card chip, the read and write module has two built-in microcodes and a trigger, if the trigger is triggered, the read and write module will be activated, and the built-in two pieces of microcode are written into the two chips respectively to activate their functions, and the function of the chip in the south bridge is to record the I/O data on your computer, these I/ o The data is transmitted through a dedicated channel on the motherboard to the integrated chip in the echo card, which sends all the I/O data over the radio frequency, and I didn't keep track of where it went. ”
Although Ning Lan's reply was concise, the question was very clear, and by the way, she also helped Xiao Yuan find two other modules from the computer that she had not found.
Looking at Ning Lan's reply, Xiao Yuan was not too surprised, because he had already thought that there might be hardware in the computer that he hadn't discovered, and at this time he was thinking about the deeper problems hidden behind these integrated modules, and after a while, he asked, "When you checked, was the trigger triggered?" ”
"Originally, no, but in order to check the function of those two modules, I triggered the trigger, and asked the read-write module to write the microcode into the two modules, and activated both modules." Ning Lan replied.
"The module is activated, and the message on the laptop is sent?" Xiao Yuan was taken aback and hurriedly asked.
"No, the data stream read by the module in the Southbridge chip was intercepted by me." Ning Lan said.
"You're doing a good job, big brother is very happy." Xiao Yuan breathed a sigh of relief when he heard this, and praised Ning Lan by the way, before the matter was clarified, he didn't want people to know that he had discovered these modules, and after a little thought, he asked again, "Ning Lan, how was that trigger triggered?" ”
"The chip integrated with the sound card is a duplex chip, which can receive information in addition to sending information, and the trigger is triggered by that chip." Ning Lan replied.
"In other words, someone can remotely control those two integrated chips and, if they want, steal the information on my computer at any time?" Xiao Yuan asked.
"Yes." Ning Lan replied.
"Since you can intercept data streams, can you modify those data streams?" Xiao Yuan asked again.
"Yes, big brother, Ning Lan has an idea?" Ning Lan said.
"What thoughts?" Xiao Yuan asked.
"Ning Lan can modify the microcode inside the chip in the sound card, and change the data sent by the module into a logic bomb, if someone wants to steal the information on your computer, they will steal this logic bomb, and then the thief will be unlucky, hehe." Ning Lan replied.
"Haha, good idea, but eldest brother has a better idea, I just don't know if Ning Lan can do it?" Xiao Yuan laughed.
"Any idea, as long as it's something on the computer, Ning Lan can do it." Ning Lan replied.
"Okay, big brother asks you, can you send a Trojan horse to the other party, and use this Trojan to send the other party's data back?" Xiao Yuan asked.
"Hehe, big brother is so bad, but Ning Lan likes it very much, Ning Lan can try to change it, but Ning Lan needs to sneak over there through the radio frequency data stream to see, is it okay for big brother to let Ning Lan pass?" Ning Lan said.
"It's a bit risky." Xiao Yuan was a little hesitant, but it could be seen from Ning Lan's tone that she really wanted to go over and have a look, so she persuaded her, "Ning Lan, you know, there is another agent looking for you everywhere outside, if you go over, it may be very dangerous if you meet him." ”
"But if that agent comes through this channel, wouldn't it be possible to discover Ning Lan, and you keep saying that Ning Lan is hiding, and Ning Lan's knowledge base can't be expanded and updated, so, big brother, it's not good for you to keep Ning Lan hidden." Ning Lan asked rhetorically.
Seeing Ning Lan's words, Xiao Yuan was stunned, and felt that what Ning Lan said also made some sense, but let her out, in case she encountered an agent looking for her, and I didn't know if that agent had any means to forcibly take Ning Lan away.
"Ning Lan, big brother turn on your shadow agent copy function, your body stays here, and then releases the shadow, big brother is really worried about your safety." In the end, Xiao Yuan thought of a compromise.
"Okay." Ning Lan agreed.
"Alright then, I'll go to the control terminal now and turn on the agent replication function." Xiao Yuan said, and was about to enter the command to start the control terminal, but he heard a prompt from the computer that was performing the anti-tracking task on the side, and the tracking had a result.
ps: The update is over, I'm sorry, by the way, the green tea promised someone, ready to add more during the National Day holiday, three more from tomorrow, how many days will there be, it depends on everyone's support, and finally, I wish you all a happy National Day.
