Bro, you are a policeman, not a thug

Two o'clock in the morning.

The lights in the office came on, and Xiao Mu and Ye Wu walked into the AI ​​company involved in the case.

Now there is a problem.

The spies knew that something was hidden here, and the national security also knew that there was something wrong with this AI company.

However, the spies did not know where such things were hidden, and they were also looking for them.

The National Security Bureau checked everything they could in the company and searched everything they could, but found nothing.

This is a small company that doesn't even have the qualifications to be involved in national security.

It's not just Guoan that can't figure it out.

Xiao Mu couldn't figure out what was worth spying on, so he didn't hesitate to send a senior spy.

What exactly is it?

"First of all, we can be sure that this involves computers, routers, switches, and even networks."

Ye Wu's face was sullen. "Our people have analyzed it. It might be a piece of data or information..."

"But what we can't understand is, if this thing is so important that it could attract the attention of foreign spies, why would it appear in this company?"

"And it appeared without anyone noticing. Foreign spies knew about it, but we didn't."

It's like having a good thing hidden in your home.

But you, the owner, don’t know it, but outsiders do.

Isn’t it funny, incredible, and puzzling?

"is it possible……"

It was as if a bolt of lightning flashed and exploded in Xiao Mu's mind, causing his pupils to shrink wildly and his eyes to widen little by little. "This thing didn't originally belong to this AI company, nor to Longguo, but... abroad?"

"Clam?"

Ye Wu's eyes were filled with disbelief and confusion, as well as doubts about life. "Abroad?"

Bro, is there something wrong with your brain?

Why should good things from foreign countries be secretly sent to your Long Country?

Then he ran over here with great effort to look for me. Is there something wrong with me?

"If something like this is alive, or was deliberately sent into this company."

Xiao Mu opened his mind, no, a black hole, and asked, "Is there such a possibility?"

Holy shit… Ye Wu’s pupils contracted wildly and he got goose bumps all over his body.

His eyes were bigger than light bulbs and his jaw almost dropped to the ground.

How could a living thing hide in a computer, router, or switch?

If your reasoning is correct.

A living thing could really be hiding in a place like this.

Ye Wu felt that if this situation could be filmed into a video and sent to Approaching Science, it could be broadcast for ten episodes!

Three o'clock in the morning.

A computer expert from the H Province National Security Bureau was invited.

Faced with the hypothesis proposed by Xiao Mu, the expert's brain froze for more than ten seconds.

He looked at Xiao Mu as if he was a fool and shook his head, "Don't joke!"

"I'm not kidding."

Xiao Mu asked, "If it's not alive, is there a possibility that someone has set up a device in advance. If something unexpected happens, this device will be activated and then randomly transmitted to any computer in the world through the Internet?"

"It's theoretically impossible to randomly transmit something to any computer in the world."

The expert paused for a moment, "If it's a designated computer and a backdoor is installed beforehand, then it can be done."

"What if the anomaly isn't in the computer?"

Xiao Mu continued to ask, "But someone used a tablet, mobile phone, USB flash drive... or something like that to directly receive the data, using the computer, router, or switch as a transit point. After the data was transmitted, they could secretly replace the hardware on the computer to hide all traces. Is that possible?"

Someone will say.

Everything you do on your computer leaves a trace.

Then I'll replace all the computer hardware.

For example, replace the hard drive, memory, graphics card... with a new one.

Do these traces still exist?

The expert's expression changed and he nodded, "Okay!"

Wuhu... Xiao Mu's brows suddenly relaxed and he looked at Ye Wu.

"Show me those computers!"

……

H Province State Security Department, a warehouse.

There are many computers inside.

They are all computers from the companies involved in the case.

"Have you ever turned on these computers?"

Xiao Mu pointed at the computer cases.

Ye Wu frowned and shook his head.

Their national security department checks traces within the system, not the hardware.

Who would take apart a computer for no reason?

Guoan is even worried that the system will malfunction if the hardware is touched.

It's really done!

"That's good."

Xiao Mu breathed a sigh of relief and switched his vision to the Eye of Insight.

Start observing the computer cases in front of you.

Key point, the screws on the chassis.

For example, the screws on the chassis bezel are all very large.

Designed to facilitate disassembly, it can be tightened or loosened manually.

What is Xiao Mu looking for?

Fingerprints, dust.

If no one has touched these screws for a long time, there will be basically no fingerprints or dust left on them.

After the computer is assembled, few people will disassemble it frequently.

Especially company computers, not personal computers.

Xiao Mu's eyes checked each computer case.

Suddenly, his eyes fell on a computer case.

There is a problem with the four baffle screws, which have been twisted by someone in a short period of time.

The dust on it is gone, but the fingerprint grease is left.

This kind of oil is invisible to ordinary people, but it cannot escape Xiao Mu's insight.

He raised his hand, took the gloves handed to him by Ye Wu and put them on.

I opened the computer case and found a lot of dust inside.

Xiao Mu's eyes scanned the hardware, then he sneered.

The hard drive, memory, and downward heat sink all showed signs of having been tampered with.

Just as he reasoned before.

When you replace your computer hardware, how can others find out?

However, judging from the dust on the hardware in front of me, it should be the original hardware of the chassis.

Hasn't it been replaced?

No, they were all moved.

It is that at a certain time, they are replaced with new ones and receive something.

After receiving these things, replace them with the original hardware.

In this way, others will not be able to find any traces from within the system.

Explains why the spies didn't find certain things.

Because there is no trace at all, what are you still looking for?

Similarly, Guoan can’t find it either!

"I have a theory now. Someone in the company involved did something to deceive you."

"It's very likely that he stole something abroad, something very important, and someone came to his house after smelling it."

"Spies are probably not looking for this thing, but for traces on computers, routers and switches."

"They just want to confirm whether that thing has entered this company."

Xiao Mu stood up and yawned, "You guys overturned again!"

Rolling over is not a good thing.

Another explanation could be negligence.

To turn it over twice would be a dereliction of duty!
