Yuan Youchong said: "Don't forget, the customs is not two sides tilting against each other, but a three-legged stand.
"o" Yu Chen was stunned for a moment, then reacted, scratched his head and said: "That is, this game is likely not to be a two-way dumping, but that the three factions will be involved and splash dirty water on each other?"
"Hmm."
Yuan Youchong said: "It may be a three-way brawl, or it may be that the two sides are fighting each other at the same time, guarding against a third party, and the third party is dormant with the intention of fighting the autumn wind." ” "However, I think that they did not hesitate to assign people to steal sensitive goods from the customs, and the plan to commit this kind of crime should be not small, and the target of the layout may be the other two parties, not just one party, or the layout itself is formed by an alliance between the two parties."
"In short, the possibility of all three parties being completely involved will be greater.
In this case, if we want to solve the case, I'm afraid it will not be easy, and the interference will be great. ” Yu Chen's face sank, nodded solemnly, and said, "You're right, there is nothing wrong with the two suspected drivers, the problem lies in the determination of Neiying's identity."
Well, the hackers involved in the case may not be so easy to find out."
"Well," Yuan Youchong said: "Lao Fan said, this hacker's technology is not bad, it can be regarded as a high-level talent, for the layout, it should still be useful in the future, it should not be regarded as a disposable product, and it will be given up after using it once." ” "Even, this hacker who hacked into the customs system may be the internal response we are looking for.
With the identity of a customs officer, and the relevant tools and equipment, he also knows what data can be changed and what data cannot be touched."
Yu Chen was silent for a while, roughly sorted out the facts of the case in his mind, and then asked: "By the way, when the signal repeater II-VI turned himself in, he brought a signal repeater, that thing."
"That thing can't actually be used as evidence," Yuan Youchong shrugged, "Repeaters or something, you can buy them at any electronic equipment store, and you can also buy them online." ” "Even if the requirements are slightly different, it needs to be used as a hub to control a certain intranet equipment, or a transit hub that integrates various functions such as remote signal transmission, integration, compilation and transcoding, etc., which can actually be bought, which is nothing more than a niche, and the biggest problem is just a long-distance problem."
"These problems undoubtedly make our laymen a headache, not to mention doing it, it is such an idea, it is difficult to sort it out, to ask questions do not know where to start to ask, but for those professional technical personnel, I am afraid it is not that difficult."
"I asked Lao Fan's Xiao Tao about this, and I remember that he didn't say that he could show us what we wanted to see what the White House toilet looked like."
Yu Chen blinked: "Directly ask Baidu about the White House toilet photo" "Uh-huh."
Yuan Youchong said: "Don't look at this guy's escape, the technology is really reliable." ” "He told me that the problem of wireless signal transmission is actually very easy to solve.
The reason why ordinary wireless signals, such as wifi signals, have a very limited transmission distance is because the frequency of these signals is too high, and they all belong to ultra-high frequency electromagnetic waves."
"Hey, I don't know the specific principle, anyway, in a certain frequency range, generally speaking, electromagnetic waves containing the same energy, the higher the frequency, the shorter the wavelength, the more limited the transmission distance, the more susceptible to external environmental interference, for example, the energy transmission capacity of 5Gwifi is not as strong as 24G" Seeing that Yu Chen had been staring at him, Yuan Youchong became more and more weak-hearted, and his voice became smaller and smaller, and finally he couldn't help asking: "What, did I say something wrong?"
"I don't know, I don't know much about that."
Yu Chen shook his head: "But looking at the stumbling points of your explanation, I always feel awkward."
I'm afraid you don't know much about it, so don't force it to explain. ” "Hey" Yuan Youchong was a little unconvinced, and was about to say a few words, but his mouth opened, but he couldn't hold back any hardcore things, so he had to cough twice and said: "Anyway, Xiao Tao said, long-distance transmission is easy to do, and the role of signal compilation and decoder is also here, which is used to translate the signal into a signal suitable for long-distance transmission, just like our walkie-talkie, the signal transmission distance is very far."
"If it doesn't work, just use repeaters to add a few base stations, similar to cell phone towers, that's what it's like anyway."
"In addition, in this device, add a hard disk for temporary storage of data, add a chip as the master control or something, and finally make a small program by yourself, you can turn it into a repeater, and it is still called a repeater with multiple functions, anyway, that's the thing."
"Xiao Tao also said that simply hacking into the intranet system and implanting Trojan horses to steal information does not need to be so troublesome at all, but if the suspect still wants to tamper with internal data and manipulate the automated management system, he will have to spend a little more time."
"Probably understood."
Yu Chen said: "Although your explanation is messy, and it is estimated that it is plausible, I think I probably understand." ” "In short, the equipment used by the suspect is not unique, as long as the counterparty probably guesses the method of the layout party, or the way of committing the crime, the equipment can be restored in a very short period of time.
"That's right," Yuan Youchong said, "so the signal repeater that II-VI picked up when he turned himself in can't be taken out alone to prove anything." ” Yu Chen pondered for a moment, then suddenly chuckled and said, "It seems that these guys are pouring into each other, and it may not be all negative interference for us to solve the case." ” "Oh" Yuan Youchong asked curiously, "How can you see it?"
"Do you think, II-VI surrendered himself, he should have been instructed by Fang Yongan, and we have analyzed it before, Fang Yongan should not be the person from the layout party, he gave us a USB flash drive and asked II-VI to surrender, these two behaviors are either counterattacks from the counterparty, or possible disruption by a third party" "But no matter what, the layout party obviously won't watch him break the previous layout, they must find a way to deal with it, at least they can't let their own people become internal responses."
Yuan You rushed to the ground: "To put it simply, the layout party has to fight back, and it must throw out the so-called evidence that has been prepared for a long time or temporarily forged, and point it at your opponent, right?"
"Yes."
Yu Chen nodded: "There are many mistakes, as long as we watch them eat dogs, and keep collecting the evidence they throw, maybe, we can directly point to the truth of the case."
"Torture and murder :
