Turing Forbidden Zone

The kiss went on and on for several minutes.

Shi Ye's hand caressed Chu Yingzong's waist, and the heat in his palm seemed to climb up.

The atmosphere gradually changed.

Chu Yingzong's Adam's apple couldn't help rolling, and her breathing became more and more hot and unbearable.

Then Shi Ye paused for a moment, as if thinking of something, he asked in thought: "Have we completed the process?"

"The process is not important!"

Chu Ying was in a hurry, and couldn't help but grabbed Shi Ye by the collar, licked her lips and said, "Hey, Shi Xiaoye, will you date me?"

Shi Ye: "Yeah."

So Chu Ying went through the process at the speed of light: "Okay, it's done!! Now you can kiss!"

Time and night: "..."

But... he wasn't actually thinking about the kiss.

Shi Ye's thoughtful eyes fell on Chu Yingzong's face, and then he thought: The preparation is not enough.

But Chu Yingzong was already enraptured by him, and couldn't help but say, "What are you looking at? Finally, you feel that the senior is so handsome that both people and gods are angry, right? Hehe, Shi Xiaoye, you made a lot of money."

"Yeah." Shi Ye replied calmly.

Chu Yingzong didn't know what he was thinking at all. Seeing that the elementary school boy still looked like an iceberg, he couldn't help but feel a little regretful: Oh, the road is long and the road is long, I have to start slowly, so I can't scare him.

Maybe it was because she took a short nap while watching a movie, but that night Chu Yingzong didn't sleep soundly, and even had a dream.

Boys in adolescence are like this... No way, sometimes they can get excited inexplicably playing basketball, let alone playing kisses under the same roof.

Chu Yingzong dreamed of the swimming pool again, and this time after he pulled the elementary school boy into the water, he couldn't help but do something...

Chu Yingzong planned to wake up halfway through the dream.

But another thought: In the dream, I should do whatever I want! !That's right, you should go uprightly!

So Chu Yingzong planned to go back and do bad things.

However, it is a pity that Meimeng cannot go back easily after waking up.

Chu Yingzong opened her eyes on the bed, and looked at her phone cautiously. It was around 2 o'clock in the middle of the night.

"Shi Xiaoye...are you awake?"

Chu Ying probed in a low voice, and found that Shi Ye should have fallen asleep.

So he sneaked out of bed and slipped into the bathroom.

There was an intermittent sound of water in the bathroom, and I didn't know what was going on inside.

Behind the black bed curtain, Shi Ye calmly opened his eyes.

In fact, he was not asleep, just browsing some gray market on his mobile phone.

——Because the work of cracking the IOS system was not very smooth at night, Shiye is going to look at the recently disclosed 0days in the online market, hoping to find some suitable collections or inspirations.

However, before he found the inspiration, he was "disturbed" by Chu Yingzong again.

This interruption lasted for half an hour, and Chu Yingzong managed to sneak out for a sneaky stroll, lay back on the bed, and sighed contentedly.

Shi Ye: "..."

Silent, silent.

Shiye decisively closed a certain gray market, and then opened another market.

He has registered an account on TB.com, but he has hardly ever shopped, and he has cleaned up the search and purchase traces very cleanly - this kind of similar cleanliness has happened to many hackers.

Shiye searched for some necessary things, and for the first time after placing the order, I didn't go to clear the history.

Because after he discovered that this item became his only search record, TB.com began to push some other items...

The door to the new world is slowly opening to him.

Shi Ye found that his understanding of certain knowledge was too in-depth and incomplete, so he had to study more.

……

The next day, both people in the same dormitory woke up early.

The strange thing is that they obviously went to bed early and on time, but at this moment, the eyes of both of them are faintly dark, and it looks more like they haven't slept well all night.

And both of them avoided talking about it, pretending that nothing happened.

After Shiye packed himself up as usual, he went out to do morning exercises.

And Chu Yingzong stayed on the bed for a while, and then received a call from Yu Jingshu.

Yu Jingshu came up and asked, "Hey, are you up at Shiye?"

Chu Yingzong said lazily, "Get up, he has to go to morning exercises at seven o'clock every morning..."

Yu Jingshu couldn't help smiling when he heard this, and said, "What about you? Little slob, why don't you exercise with Ah Ye?"

"One, exercise together..." Chu Yingzong suddenly got stuck suspiciously, "I just didn't get up!"

"Okay." Yu Jingshu said, "Ah Ye won't answer my phone, so I can only ask you to tell him: I've greeted their department, and he doesn't have to sign in for the basic courses for freshmen in the future. At the end of the month At that time, the head teacher will arrange a general exam for him, as long as he passes it, he will be exempted from the course, and his usual grades will not be counted."

"Wow..." Chu Ying was about to drool enviously, "Why did you give him such a pleasant treatment all of a sudden?"

Yu Jingshu laughed: "This is determined by his strength. If you want, you can also take the exam with him. If you can get more than 95 points in all subjects, you will be added."

"Forget it." Chu Ying lay back on the salted fish, "I just watch him quietly and feel good."

Yu Jingshu smiled for a while, then said, "Ah Ye may be busy this week, so don't bother him too much. How is the dormitory life going?"

"It's okay." Chu Yingzong replied casually, and then asked a little suspiciously, "Why do you suddenly start to care about Ah Ye's daily life again? What does it mean that he may be busy this week... Are you two secretly in the room?" What are you discussing?"

"That's not true." Yu Jingshu said without leaking, "The teacher can be regarded as entrusting A Ye to me, of course I have to pay more attention to it. Ying Zong, I hope we will be a family in the future, you think so too, right?" ?”

Chu Yingzong got stuck again.

--"family"? !

Although he knew that Yu Jingshu meant something else, but at this moment he couldn't help thinking about it, his face turned red, and he hesitated and said, "Let's talk about it again."

Then hung up the phone.

Yu Jingshu: "!!!" This kid, Ying Zong, did he finally acquiesce? !

In the past few years, Yu Jingshu has taken care of Chu's mother, who is close to the water, and has been in love for a long time, so he can't help but want to go further.

But Chu Yingzong is still a young man, and his resistance to Yu Jingshu's stepfather is seen by Chu's mother, so of course it is impossible to disregard his wishes.

Now... Chu Yingzong seems to be letting go?

Yu Jingshu was so excited that he was so happy that he couldn't help himself. He dug out the address book and sent a message to Chu's mother: [When this matter in my hand is finished, we will go on a trip with Yingzong and Aye. A few days.Ah Ye also agreed, and Ying Zong also agreed. 】

Mother Chu quickly replied: [Okay.The end of the year is approaching, and my unit is also organizing a trip recently, why don't we take our two children to the playground? 】

Yu Jingshu suppressed his excitement, pretending to be calm and replied: [Okay, then I will start to prepare. 】

"yes!!"

Then Yu Jingshu jumped up directly from the office chair, regardless of the attention of the younger brothers behind him, he happily fisted twice on the spot, then brought back his coffee, and started a new round of overtime work with a happy face.

So, things went in circles and circles.

When Ye Chen came back from practice at that time, he found that he had received another text message from Yu Jingshu.

[Yu Jingshu: Has the matter progressed?I will work night shift this week, you can find me anytime. 】

After thinking about it for a while, I rarely replied with a text message:

[It will take a little longer than expected. 】

Because, now he can no longer work hard for three days and three nights, and there is still a stupid senior in the dormitory who is "interfering" with his work and not allowing him to overdraw his body.

What an annoying clingy senior.

With such worries in mind, Shiye didn't go to class today.Sure enough, as Yu Jingshu said, the higher ups had already greeted the school.

During the day, when Chu Yingzong was not around, he would retreat and meditate every night.

Cracking a system is an interesting game for him, just like when he was a child, he was exposed to Sudoku for the first time; like in a hacking contest, thousands of troops invaded a server, and he had to seek all kinds of possibilities for this. path of.

The mobile system cracking in the traditional sense is generally divided into the following steps:

First, enter the recovery or DFU mode of the mobile phone, and perform a REBOOT to obtain the write permission.

Second, start to guide the system to write data, and obtain the operation permission of the cracking program.

Third, under the permission to run, start to install the crack package.

Fourth, after the crack package is installed, end the recovery mode of the mobile phone, start the normal operation of the system, and run the crack package.

The fifth and final step is to let the cracking package finish running, then REBOOT again, and start to guide the cracking system, and then declare that the phone has been cracked, commonly known as "jailbreak".

At present, on Zerodium, the world's largest 0day black market, some people are already packaging and selling IOS cracking packages and related vulnerabilities of past generations.

These things are not expensive, because "expired 0days are not as good as dogs", as long as anyone is willing to spend some time, they can always collect them all on a large number of dark web and gray and black markets.

Shiye bought the source code of the previous generation Unc0ver crack package for only a few cents. Its own principle is to use a font file vulnerability in a FlateDecode data stream to perform jailbreak.

Through refactoring and partial rewriting, he got a crack package that suits his own rhythm.

But this part is not difficult, the real difficulty is how to bypass the authentication of the IOS system - because the vulnerability used by this old crack package has already been fixed by the new IOS version, so Shiye must find a new 0day.

This vulnerability must be serious enough to allow an original iPhone to install such an unknown software, that is, to obtain the write permission of the Kernel core.

For the native IOS system, every time you install software, you must verify a software certificate—the certificate is usually issued by Apple itself, or by a third-party organization they trust and designate.

Software that has not been audited by Apple, of course, does not have a certificate.

This is like a person who wants to go through customs but does not have a passport and a visa, which seems absurd.

Now, Shi Ye's eyes fell on this certificate.

——Just in January of this year, Microsoft updated the algorithm of their elliptic curve cryptography certificate, which is the 1th generation passport of the computer world.

But the author is too lazy to pretend to be so forceful, so please make up your mind.
