Chapter 7: Ransomware

After a while, Bai Siyu said with a smile: "This hacker technique is quite high......"

Jiang Huairen, who was standing on the side, was happy, "What's the matter, just say that he doesn't have that ability, it's obvious that he is here to make trouble."

Bai Siyu glanced at him, how could this person always like to interrupt others, and sneered: "The virus he made is called a ransomware virus"

"Hey, old man, have you heard of it?", Bai Siyu touched Dr. Liu next to him with his elbow.

Dr. Liu thought for a moment and said, "I remember, when I was still in college, I heard from my teacher that this virus spreads through emails, web pages or links, and once the computer is infected, all the documents and important files on the computer will be encrypted. The infected person cannot decrypt it, and can only get the private key for decryption by paying a ransom, but ......"

Bai Siyu continued: "Dr. Liu is right, this virus first appeared in the 21st century, older than everyone present, so most people don't know, at that time the computer was still XP system, but the current system has already fixed this vulnerability." ”

Everyone was at a loss, since this vulnerability had been fixed a long time ago, why would it be infected again?

Bai Siyu saw the doubts of the people around him, smiled secretly in his heart, it was time to show his talent again, and said with a smile: "Because, this is a new type of ransomware virus, and its transmission method is different from before, it comes in through the remote port of the computer, and then encrypts it through a complex algorithm." ”

The scientific researchers on the side were about to re-examine this man who seemed to be a street gangster at this time, and he actually had some ability, and instantly turned into a look of admiration.

He Ying was also very relieved at this time, and sure enough, he didn't find the wrong person. "Can that be unraveled?"

It's said that this is a new type of virus, is this woman stupid, how can it be so easy, Bai Siyu thought in his heart but didn't say it, "Well, it's theoretical, I think you have to thank this hacker." ”

Everyone suddenly didn't understand, I have to thank him for hacking our system.

Bai Siyu said: "I analyzed these encrypted files and saw that the head and tail of the files were very complete, which shows that the virus made by this hacker is very perfect, and in the process of encrypting the files, it did not damage the files themselves, so he is a hacker with good technology." If you encounter a poor technology, the virus will damage the files when encrypted, even if there is a key to unlock them, in the end these files will become a bunch of garbled garbage, do you want to thank him? ”

What kind of genius logic is this, it can only be a blessing in misfortune.

"Dizi, decompile this ciphertext, correspond to the password database, and see if you can find the same password. ”

Hearing the sound, Dizi took out a laptop from his backpack and put it next to the computer in the research room, connected it with a data cable, and began to operate.

After a while, Dizi shook his head: "Ayu, no"

Bai Siyu was a little puzzled, how could they not have all the combined passwords of 0-9 a-z in their Bai Jun's password library. Then I looked at the flute computer screen and really didn't find it.

Jiang Huairen looked at the anxious Bai Siyu with a wicked smile on his face, and said: "I have already said that he can't do it, and Mr. He quickly blew this person away, so as not to destroy the documents." ”

He Ying asked Xiang Bai Siyu: "How is it, is there no way?"

Bai Siyu said impatiently: "Eldest sister, there has always been a fly here, which affects my work very much. ”

He Ying looked at Jiang Huairen, and probably couldn't stand him chattering here and saying cool words, "You go out first, and take a half-day off today." ”

"Mr. He, I ......", Jiang Huairen looked at He Ying with a cold face, didn't dare to continue, and walked out with a belly full of fire.

Bai Siyu looked at the computer's decompiled password, and said to Dizi: "Dizi, is it possible to encrypt the encrypted text twice, and encrypt the encrypted ciphertext at one time." ”

"Oh, Ah Yu said that, it's indeed possible, I just felt that the decompiled password arrangement was a little familiar. ”

"Then you do one more decompilation. ”

"Okay", said the flute on the computer, and performed another decompilation.

"Ayu, there is, there is", the flute suddenly shouted excitedly.

Bai Siyu looked at the decompiled text: "19951205, this is like a date of birth." ”

"It must be the hacker's birthday!", Dizi said.

Bai Siyu hurriedly entered the password on the locked computer file, and then an electronic prompt sounded: "The password is wrong, there are two more chances." ”

"Wocao, there is still a limit to the number of times", Bai Siyu couldn't help but scold, it seems that he underestimated this hacker.

Dr. Liu, He Ying and others were also stunned in place, and Bai Siyu was at a loss for a while.

After a pause, Bai Siyu asked, "Dr. Liu, what is the contact information of the hacker?"

"A mailbox, that's it. ”

Bai Siyu glanced at the email account, "ANONYMOUS, anonymous, this should be the code name of hackers, generally hackers will use their code names to set passwords", now there is no other way but to try.

Then type "ANONYMOUS19951205" on your computer

"Wrong password, one more chance"

Suddenly, the scientific research room was agitated, "Is this person good or not", "If you really break the document, it's better to give the hacker money", everyone blamed this man who was still worshipping just now.

Only He Ying didn't complain, and said to Bai Siyu: "Don't be nervous, you think about it carefully, maybe there is something missing", but his face looked a little embarrassed, after all, there is still one chance left, if it is all wrong, I don't know if the document will be destroyed, I have never doubted that Bai Siyu is a little worried at this time.

Bai Siyu was extremely embarrassed, this was a little early, but he didn't worry about the bet with Jiang Huairen, but now if all the opportunities are used up, he really can't go back.

Trying to calm himself down, he silently said to himself: "ANONYMOUS is the hacker codename, 19951205 is the birthday, 1-9-9-5." ”

"By the way, it's 19951205 birthday", Bai Siyu shouted as if he suddenly realized, his eyes shining brightly.

Everyone looked at each other, didn't they lose their birthdays for the first time?, and they all prompted the wrong password.

Xiao Jundi reminded: "Ah Yu, I tried it on my birthday, no!"

Bai Siyu stood up, swallowed his saliva, paused and said, "The first time, we entered this birthday, no." It is also wrong to enter the code name and birthday for the second time. Do you know why? Because this birthday is not the hacker's birthday at all. ”

Listening to Bai Siyu say this, it is true that from 1995 to the present 2108, if it is the birthday of this hacker, he is already 113 years old, and it is undoubtedly a miracle that he can live so big, and the computer is still playing so slippery.

"Whose birthday will it be?", He Ying asked puzzled.
