However, what makes Li Jun very sad is that even though he now knows a lot about the program, he is still very weak in terms of hardware.

In the end, I couldn't help but look at how to extract code from this vulnerability given by Eagle Eye, and I figured it out.

After understanding, Li Jun was also full of praise.

Microsoft's genius, or rather Sam's intelligence agency pervert, actually uses the fixed memory buffer in the hardware.

The monitoring device uses a fixed memory buffer to receive user input when processing RTSP requests.

When a user sends a request for data that exceeds its storage length, the requested data covers the memory space outside of the fixed data set. This eventually results in a server-side buffer overflow.

Because the overflowed memory space is overwritten, when the overwritten part is malicious code written by the attacker, the malicious code can change the program execution process on the server side by overflowing, so as to execute the malicious code to manipulate the device.

This would have been a very simple cache overflow vulnerability that almost anyone who has studied hacking techniques understands.

However, when combined with the computer's surveillance device and RTSP requests, and with a specially designed mask in the hardware, it simply cannot be detected.

Even if someone inadvertently discovers a memory overflow, it will be treated as a normal cache shortage of the system.

But Li Jun had some doubts.

According to the revelations of later generations, the Prism Gate incident only started this plan in 07.

But now the vulnerability exists, and it's cross-OS at all.

It's incredible.

Could it be that Uncle Sam had already started to lay out so early?

If that's the case, then Sam's scheming is too deep.

Li Jun felt very powerless, this vulnerability is not so easy to block, if you directly close the RTSP request port, then the computer is almost useless.

I can't even receive the user's own request, how can I use it?

This is already the underlying vulnerability.

Although Li Jun understands that the data leaked by this vulnerability is not so exaggerated. But know that there is a group of people in the world called intelligence analysts.

They can deduce the truth from the slightest clue.

Li Jun couldn't solve this problem by himself, and even Hawkeye was also troubled by this problem at the moment. For him, this is even more important.

You can't assemble the memory module and change the mechanism of the system reading the memory yourself, right?

After all kinds of hearts and helplessness, Li Jun had no choice but to hand over this task to Meng Meng.

After Mengmeng glanced at it, she asked Li Jun very curiously.

"Brother, is there anything wrong with this?"

Li Jun couldn't react a little.

"Isn't there a problem?"

"No! Cache overflows are normal! ”

Li Jun looked at Meng Meng speechlessly.

Does Meng Meng really not understand the attack methods of hackers?

Then Li Jun told Mengmeng about the dangers of this loophole and some things that could be done.

Meng Meng said innocently: "I know! I know I can do this, but so what? Just add the entire operating system to a shell. ”

"Huh!?"

Packing!? You think it's shelling a program! It's a matter of the entire operating system.

"Also, your operating system sucks. It's ......."

Well, what an idiot to discuss the issue of the operating system with a program that can already be called intelligent life.

But...... Maybe it's an incredible thing for people to pack an operating system, but maybe it's quite simple for Meng Meng.

Then I saw Meng Meng with a face full of contempt for a while on the floating panel in front of him.

"WELL, WE'VE PACKED THIS SYSTEM CALLED WINXP, WELL, AND BY THE WAY, IT'S BEEN OPTIMIZED. It's been transferred to your computer. ”

The corners of Li Jun's mouth twitched as he looked at a compressed bag on the computer desktop.

Meng Meng has been optimized......

Li Jun was a little overwhelmed, and unzipped the installation package tremblingly, and then saw a disc-shaped icon.

Right-click, Properties.

Size 20480M.

"Just two Gs?!"

"Hey," Moe smirked. "Actually, there is no 2G after optimization, but I recently found that I seem to have a bit of obsessive-compulsive disorder."

What do you mean by finding out a little obsessive-compulsive lately!?

Isn't OCD innate? Also, I'm talking about 2G and I'm already surprised by the size of the installation package!

"Then, I added some code that didn't work hard to make the visuals better." {

Okay, Mengmeng, I know you're powerful, but you don't have to be like this, right?

I thought it was just a package for the operating system, but I accidentally optimized it.

Li Jun was also curious about what the optimized WIN system would look like, and double-clicked the installation package tremblingly.

The installation screen is very concise.,There's no variety of terms.,There's no other installation location and what's next.,There's just one installation.,Cancel the pop-up window.,It's extremely concise.。

Li Jun clicked the install button.

The computer screen went black in an instant, and the full screen began to swipe down the binary code.

Well, sure enough, I guessed correctly, Meng Meng directly converted the system into machine language, and it is also the most basic kind of representation of high and low voltage signals.

It is not a binary that has already been encoded.

As the code was refreshed, in less than two minutes, a familiar boot WIN screen appeared in front of Li Jun's eyes.

Li Jun looked almost unrecognizable, these various shades and frosted glass effects were simply intoxicating!

THIS SEEMS TO BE ONLY AVAILABLE IN THE LATER WIN7 AND WIN8 HIGH-ENERGY MODES.

And because this kind of drawing puts too much pressure on the CPU, many people directly disable this visual function in order not to make the system lag.

When the desktop was presented in front of Li Jun's eyes, Li Jun was a little stunned.

This is because it doesn't feel any different from the original system. Aside from the fact that the icons are more comfortable to look at, there doesn't seem to be much different.

After using various versions of the operating system in the future, Li Jun did not feel any discomfort, and he still had a good sense of intimacy.

However, when Li Jun installed all kinds of software, he began to be shocked. It's too fast.

When Li Jun installed all the software, he was completely stunned in front of the computer.

Whether it is the speed of opening the software, or the operation, it seems that there is no pressure, even if it is a variety of drawing software, this is also true!

It can be said that this system has been handed down by cute hands, and the hardware performance has been brought into full play!

Li Jun's eyes glowed green.

Money! A business empire! That's a lot of money!

Involuntarily drooled saliva, pulled out a long silk thread, and dripped onto the desk.

Meng Meng looked at Li Jun curiously.

What the hell is this shiny thing?
