At this time, the pop-up window that has remained unchanged for thousands of years suddenly changed!

No more new topics appear, and the pop-up window completely disappears.

In its place is an all black website page.

Countless codes flashed in a hurry, and finally turned into two white Chinese characters composed of countless "1" and "0"——

Extreme night.

What the hell is this?

Seeing this, Lin Xiaotang was stunned for a moment.

She thought about it, shook the mouse, and tentatively clicked the word "polar night" in the center of the screen.

Soon the web page disappeared, replaced by a fairly neatly styled forum.

To enter the forum, you need to register a forum account first.

Seeing this, Lin Xiaotang quickly registered as a member, changed his ID to "Big Devil", and logged in.

She has done the question for so long, not just out of competition.

She also wanted to know what was behind these topics.

After successful registration, the page will jump.

After a while, Lin Xiaotang saw the full picture of this Jiye Forum.

There are many posts on the forum, but the number of registered members is only more than 200.

Lin Xiaotang hurriedly looked over and found that the posts here were either discussing some programming issues or playing dumb puzzles with each other, as if they were doing some kind of transaction.

[Help complete a set of C7 tasks, old rules. 】

[Who can do the red domain design and management of A9? 】

【Does anyone know about the S area? 】

It can be seen that these people speak very carefully.

Many professional words have been referred to by them with other words.

Perhaps out of intuition, Lin Xiaotang thought about the questions he had done before, and then looked at the titles of the posts in the forum, and gradually came up with a guess in his heart.

hacker.

Under normal circumstances, a secret forum with a small number of people is either a "dark web"-like existence or a place where a very small number of special groups gather and communicate.

For some reason, their identities may still not be visible.

Considering that the people here are all programmers, not ordinary programmers, Lin Xiaotang easily thinks of hackers.

She really didn't expect that she came in in such a place.

Still, that's not a bad thing.

...

At the same time, in a certain group in the country.

[Blue: Someone solved our problem. 】

There are only 7 people in this group, and most of them don't usually speak. Their avatars are black for a long time, and they look quite low-key.

But with the appearance of this sentence, many members of the group appeared instantly.

[PHP is the best language: wait, are you talking about those questions when you entered the forum? 】

【Blue: Hmm. 】

[PHP is the best language: ... how many unlocked? 】

[Blue: All. 】

After seeing this news from Blue, everyone was silent.

A few seconds later, the group members sent a new message.

[So bald: No way... Those questions, can someone really do it? ? ? 】

No wonder they were so excited.

Because these questions are really too perverted!

You know, those questions were basically thought of by the top domestic hackers.

And when they designed this test, they didn't even think about letting others pass the test!

Each of the questions here has a very large span and is quite difficult, requiring the answerer to have a huge knowledge reserve.

That's fine, but these questions must be given within 30 seconds.

Even a senior math expert can't solve 99 questions in one go at such a high frequency!

In order to prevent the answerers from "cheating" by searching for software and calculators, they also set up a program to cancel most of the functions of the computer when answering the question.

The person answering the question can only answer the question by entering numbers and letters, and nothing else can be done.

With these 99 top-difficulty questions, even if the website of their forum were accidentally leaked, it would be difficult for anyone to successfully break in.

But who would have thought that just today, someone actually answered all these questions in one go!

This kind of situation made them feel aggrieved and inexplicable admiration.

Such people, let alone in their hacking world, are rare geniuses even in the world.

But who is this person? !

In the exclamations of everyone, the administrator came out and gave the final order.

[Dog management: No matter what, this person must be found. 】

[Dog management: Since he can solve our problem, it means that the level should be similar to ours. We have to find a way to pull him into the group! 】

...

How shocked the people in the group were, Lin Xiaotang didn't know for the time being.

She also thought that the 99 questions to be answered when entering the forum were the tests that all members of the forum had to go through.

After confirming that this forum is a hacker forum, she did not hesitate at all, and immediately began to learn the knowledge inside.

I have to say, as the most private and top hacker forum, there are a lot of related technical posts on Jiye.

These great gods do not have much idea of hiding their secrets, and they have published a lot of programming experience and insights.

Lin Xiaotang browsed all the way, and slowly learned a lot.

Before entering here, she will only have the most basic programming.

More esoteric technical content, she is difficult to learn from books.

However, now it seems that this is not a big problem.

Hackers' techniques fall into two main categories: red domain (offensive) and blue domain (defensive).
