Chapter 103 105. [Shenhai + Meimo] How to crack the Mao-style code

There is a cabin of more than [-] square meters in the most core position in the center of the hull.According to the structural diagram, it is the central computer that controls the entire ship.This has to be seen.

After swiping the captain's IC card, the display screen near the cabin door responded.

"Please enter the password."

Looking at the green characters on the screen, Nan Xiao fell into a daze.I really saw your ghost, why do you need a password after swiping the IC card?This unscientific!

The captain has a small diary with him, in which he wrote many memo-like things, but it was very scribbled, and it was in Russian.

Fortunately, the mobile phone can translate Russian, which is not smooth but understandable.After rummaging through it, Nan Xiao found that an eight-digit password is needed here.The first seven digits can be found in the diary, either numbers or letters, but the damn eighth digit is not remembered.There is no way.The captain wrote it for himself, even if he wanted to leave a hole, there was nothing he could do about it.

26 English letters plus ten numbers, a total of 36 options.

Nan Xiao dared to bet that it was absolutely impossible for him to try and make mistakes more than 30 times calmly.

What to do, I can only think of a way to brute force it.

After touching it up and down for a while, he really found a way.There is a steel plate near the display that feels obviously different from the surrounding area.He found the seam and pried it hard a few times, and it was loose.After prying for a while, the fastening screw slipped.With a strong force, the steel plate was completely removed, exposing the circuit board inside.

Seeing the familiar circuit board, Nan Xiao couldn't help thinking of the days in Vault 101.There, I was forced to learn a lot about electrical circuits.Check out these cute capacitors!This beautiful pin!This neat chip!He touched the circuit board.Wow, this feel, this sense of touch... It's been a long time since I touched a hardware circuit, and I really miss it.

The eerie refuge, the days and nights spent alone...

This is how growth comes about. I have no regrets in the three years of loneliness!
After studying the circuit board for a while, Nan Xiao reconfirmed: there should be no difference between the physical principles of this world and the radiation plane.At the very least, the design principles of digital circuits are exactly the same.For example, this jumper seems to be used for debugging by maintenance personnel, and it can definitely make some articles.

Pip-Boy comes from Shelter 101. Nan Xiao plays with it whenever he has nothing to do, and he is already very familiar with it.It happens to have a wire specifically designed to crack circuit boards, and it was born to do this job.

After plugging in the jumper, a flickering cursor appeared on the Pip-Boy's display screen.Nan Xiao was excited, the familiar command line mode came!

The next step is to master the basic operations.Log in in maintenance mode, set the password file permissions to open to yourself, and then open the password file in DEBUG mode...

After breaking countless passwords in Vault 101, Nan Xiao is very familiar with these.The password file was filled with piles of garbled characters, which he ignored.Only words that made sense were valid password combinations, and he'd known that for a long time.

On the screen, there are a total of [-] legal password combinations, all of which are short sentences of eight characters. You can select any sentence to enter by moving the cursor.

There are only three chances to break through.However, after some searching, Nan Xiao found that there were four groups matching the top seven!What to do?Means there is a possibility of failure.

With the idea of ​​trying his luck, he tried a group at random.

"Drip!"

A ruthless message appeared on the screen: two chances left.

Is it that bad?He tried another set.

"Drip!"

Oh, there is only one chance left.If I make another mistake this time, maybe the ship will explode.I'm not joking. When he deciphered the password file just now, he found some fragments of garbled characters, which seemed to mention that there was a self-destruct bomb on board.

The warning flashes repeatedly on the screen: If you make another wrong input, the system will lock up and enter an indescribable state.

Rubbing his face, Nan Xiao tried to calm himself down.Don't be afraid, think about the experience of cracking various circuit boards in Vault 101, this thing will definitely leave a back door!

After poring over the traces, he ventured to create a short between the two capacitors.This small trick does nothing to break the code, but it should break the chip's counting of input errors.

it should be OK?

A voice in my mind questioned: Are you sure it's okay?If the count isn't ruined, you'll be screwed if you make the wrong choice.How sure are you?
... Let's open fifty-five.

Only 50% sure, dare to take risks?

Otherwise, what else can I do, I can only gamble.Big or small, just turn and stare.

Nan Xiao almost closed her eyes and chose the third set of passwords.

"Drip!"

Another error message occurred and it failed again!It's over, I'm going to die, I'm going to die!
However, there was no sound of bombs exploding, and everything was as usual.He boldly looked at the screen, and found that the error count had indeed stagnated, and remained at the last time.

Yes!The broken circuit board was really deceived by the bird!

There is no suspense about what happens next.The first three sets of wrong passwords have been passed, and the remaining set is naturally the correct password.Sure enough, after selecting the fourth group and pressing OK, the small horn on the hatch circuit board rang out.Although it was just a very simple midi sound, it was no less than the sounds of nature in Nan Xiao's ears.

After the certification is passed, the next step is the green light all the way.The system has switched to the login mode, and there are rows of prompt messages.Soon, Nan Xiao logged into the ship's management system as an administrator. Root permissions!He rubbed his hands skillfully and smiled badly: Just wait for nothing, the uncle is here!

Nan Xiao wants a lot, not just to open this door.After finally breaking through the management system of this ship, of course it must be done thoroughly so as not to leave any future troubles.

The cursor blinks on the screen.The system has given up resistance and is waiting for luck.Sorry, you can do whatever you want with Root permission.He immediately opened a new account for himself, gave him the highest authority, and then changed the owner of the captain's IC card.Another account in the administrator group?Cut them all off!Factory preset backdoor connection?Delete them all!Unclear open port?Block them all!Regular data exchange with the bases of the Northern Fleet?Strictly prohibited!

In a blink of an eye, the ship became a data island, and the connection with Lucia's base was completely erased.There is no one with higher authority than Nan Xiao on this boat.

After cleaning up to the end, I found some interesting things.

There are some text files left in the system administrator directory, the last date is yesterday.Nan Xiao opened it casually and found that it was left by the captain.Unexpectedly, the captain would secretly write a diary under the system administrator directory.Presumably he thought the directory was a secret and no one could gain access except him.

08/15/3102 22:38:34 ——
The day after tomorrow is Natasha's eighth birthday.Although it’s not good to use precious bandwidth to send private files, I still recorded a video wishing her a happy birthday.As a captain, you should have this little privilege, haha.

In addition, the birthday present is also prepared. After this mission is over, I will give it to her when I return to the port.

Note: Gifts are kept in the personal locker in the captain's cabin.
