Turing Forbidden Zone

That night, people were surprised to find that Signale suddenly caught up!

He broke through the fourth level at 18:31 Beijing time, and then broke through the fifth level in just 1 hour and 20 minutes!

At that time, even Kirito, who was famous for breaking the level, was blocked before the fifth level.

The leaderboard has undergone earth-shaking changes.

1. Signalle7800

2. Kirito7200

3. Blady7050

……

However, when everyone in Huaguo was rejoicing and wishing they could blow a wave of Signale on the forum, they were stunned to find——

Signale has been quiet again since this time of night.

Until 7:00 the next morning, Kirito, who had not slept all day and night, broke through the sixth level and completed the overtake of Signale.

Everyone expressed shock one after another, and many discussion posts on this phenomenon have sprung up on the forum.

【What's the situation with God S? ?In the evening, the dragon and the tiger suddenly became fierce? ? ?Changed, or drugged? 】

[Hehehe, it was a flash in the pan, probably because of luck, the fifth level happened to have a loophole that he knew about. 】

[Impossible, I don't believe that there are programmers who go to bed at nine or ten in the evening! !I don't believe that there will be people who go to bed on time and win the first place in the scoreboard in the hackathon!A bald programmer who doesn't want to be a night owl is not a good hacker! ! ! 】

……

The administrator of the flower field, xyzabc123 looked at the post and lit a cigarette in the vicissitudes of life.

"Oh, stupid mortals..."

"Intermittent blockbusters, continuous mysterious disappearance-this is the typical characteristic of God S...it is him, that's right."

From the second day of the Masters, the hackers at the top of the leaderboard seem to have coincidentally started to enter their sage time one after another.

With Signale at the head, followed by Kirito who came in second and hibernated after 6 hours, then Blady, and then more unpredictable people in the back row.

They are like bats lurking in the night, dormant and resting with the dawn, and waiting for the next night to come.

The game lasts five days, and they have plenty of time.

Continuous, high-intensity mental work can easily drain a person's entire mental strength, which is why hackathon is a combination of "hack" and "marathon".

Throughout the second day, the average score of the hackathon was still the second level, while the first echelon advanced to the sixth level;

On the third day, as a large number of people gave up and became gray names on the leaderboard, the median of the hackathon reached the third level, while the first echelon entered the seventh level—the difficulty of this level is marked as "Heroic", heroic;

On the fourth day, there were only 11 well-known famous hackers left in the first echelon team headed by Kirito, and they advanced to the eighth level - "Epic", the epic level.

The requirements of the eighth level are: break through the professional firewall specially set up by the world-renowned security team ProjectZero for enterprise-level servers, crack the core key after hashing and salting, and finally access the non-relational database with double authentication, and get the final ninth level from it. closed entrance.

At this point in the standings, after the 11th place, there is basically no chance for the final battle, but the front row points are clenched even tighter - because starting from the eighth level, every bit of progress will be scored separately.

No.1, Blady10551 points;

No.2, LC_King10241 points;

No.3, Kirito9911 points;

No.4, Signale9814 points;

……

At this time, in an officially listed team in Huaguo.

Their siege master has already given up, and with thick dark circles under his eyes, he spread his hands to Yu Jingshu: "This difficulty is beyond my control. The Google team also has a Turing Award reserve, and their technology is ahead of us At least five years in China, if I want to crack their shell, it is enough for me to publish at least three top issues..."

Yu Jingshu frowned, and asked, "Can you really pass the difficulty of the eighth level?"

"I can pass." The siege engineer replied, "One possibility is that these people have the support of galaxy-level supercomputers behind them; the other possibility is that they may have long regarded Google's technical team as their own backyard. I’ve been shopping around. Of course, maybe their technical means are beyond my scope of knowledge, but no matter what kind, I can’t give any advice at the moment.”

Graduate School of Information Engineering, Sakura Kunisaki University.

Kirito quietly faced the flashing information on the screen, took off the work card on his chest, rubbed the corners of his eyes wearily, sighed, and told the students: "Apply to the above for the permission to use the supercomputer Post-K, everyone Sir, this is the limit of what we can do."

"gentlemen……"

"Our algorithm has a limit after all, and this time it was reconfirmed. The hash and salt cracking method has a famous violent aesthetics. I hope that Post-K, coupled with the 2TB rainbow table of Dongda University, can be completed in time." It brought miracles before..."

4 hours and 8 minutes on the fourth day after the start of the Masters.

At a public intelligence center in the White Eagle Country, an illegal physical connection was pulled to a certain mobile workstation, and the flash of its screen briefly illuminated Blady's side face.

Sitting cross-legged outside the high-voltage power grid, Blady said to himself: "If someone can brute force crack this key... I really want to see what his rainbow watch looks like, it must be a soldier who has experienced many battles."

On the screen, Fennel's processed electronic voice came: "I believe Signale can always surprise us."

"I hope." Blady chewed his gum and said vaguely, "After all, we have sponsored more than 120 million US dollars in this competition, so that he can see us. However, if I can get his rainbow watch, I will Just admit it was well spent.”

Fennel said: "Don't worry, my lady, my instincts are always right: We're in the same boat as Signale. He may not want the title, but he definitely wants to get to the end, and he can't help but say, 'Truth. ’ is the best drug, the highest pursuit for people like us.”

Blady: "I really don't understand, is it important for us to join Signale?"

"Very important." Fennel said, "In order to get his assistance, my bottom line is all organizational resources, 100%. You may not know that this man's mind is worth more than the world's best supercomputer."

Just 10 minutes into the conversation.

The ranking on the official website of the Masters suddenly flashed and changed information after a long silent stalemate.

No.1, Signale, 12814 points.

……

He broke through the eighth level and got the key to the ninth level!

After that, the whole forum was boiling for Signale.

Although almost half of the people stopped at the second level, even though most of them could not understand what the difficulty of the eighth level meant, this did not prevent them from emphasizing one point——

【Signale is the world's worst hacker! ! ! 】

Although they don't know it, the subtlety of the eighth level is that once someone breaks through the firewall and finds the entrance to the ninth level in the database, it will immediately leave traces in the database index.

And even if the latecomers fail to crack the key, they can also obtain the index through operations with lower difficulty, which is equivalent to walking on the road opened by Signale and stepping into the ninth level.

No.1, Signale, 12814 points;

No.2, Kirito, 11911 points;

No.3, Blady, 11551 points;

……

However, this standings seemed to be frozen for all the subsequent time and never changed again.

Because the ninth level made everyone silent.

22 hours and 8 minutes on the fourth day.

As if knowing what hackers all over the world are paying attention to, Kirito appeared in real form on the first level forum and announced in English:

[I give up competing for the points of the ninth level, and give an approximate form of the topic to facilitate the judgment of latecomers.

The difficulty of the ninth level is "Impossible".

Its main content is: get a transaction record - the record of a cross-border transaction in the Southern Cross Bank. 】

As soon as the post came out, it caused an uproar again.

The forum is no longer full of exclamation points, but full of question marks.

[Is there something wrong with my eyes, or something wrong with the organizer, or something wrong with this world? ? ? 】

……

After Yu Jingshu finished watching, he calmly informed the team: "Let's end the show. I will finish my two-hour shift at the end. This 'impossible' difficulty is really impossible."

……

xyzabc123, who was watching the battle peacefully, sprayed coffee directly from his nostrils.

"Holy shit! How fattening this hackathon is! The eighth level is just to rob Google, and the ninth level is even to rob a bank!!! Why don't you just ask God S to ascend to the sky and stand side by side with the sun? !!"

Of course, obtaining the transaction records in the bank does not mean robbing the bank.

But its significance is: a hacker who can do this can basically transfer money from any bank account to himself.

He can even realize a famous sci-fi story that someone imagined on a social platform through batch operations: [If everyone in the world gave me one yuan...]

In fact, the reason why Southern Cross Bank’s online trading system participated in this hacker masters competition was not really wanting to be robbed—although they provided an exemption agreement, all attacks on them by hackers today are only The operation is an "exercise" and does not have to bear legal responsibility.

But in fact they are just advertising.

Well, advertise.

The truth sometimes seems ridiculous, but it is the truth.

Just like manufacturers of bulletproof glass who always like to beat up their products with various guns, the security experts of Southern Cross Bank also deeply trust their proud work and are willing to challenge top hackers all over the world .

——Whoever can break through their "bulletproof glass" and get the transaction record representing customs clearance will receive an unconditional employment notice from the world's top bank and a champion bonus of 800 million US dollars.

Such a high bonus can only show one thing:

They have absolute confidence in their security level, which is the heart of the ocean in a bulletproof glass cabinet - for all to see, but never for anyone to touch.

This is the best advertisement for bulletproof glass.

There is 1 hour and 52 minutes left before the end of the Hackathon Masters.

The key leading to the banking system of the Southern Cross country is divided into two parts, which are composed of the passwords of the two security directors, the principal and the deputy, and undergo an irreversible one-time encryption operation to form the final complete key.

In addition, four-factor authentication of iris, voice, fingerprint, and password is required.

But at this time, when the supervisor saw the remaining 2 hours, he had easily thrown his mobile phone into the water of the family pool, lay on his beach chair, held a glass of red wine, and enjoyed this rare paid vacation .

——As long as I isolate all electronic devices, no one can collect my irises, voice and fingerprints, hey!
