Computer Security Laboratory, Jinghua University.

This is a national key laboratory, which is a temple in the eyes of those who study computer security.

In front of the plain white experimental table, Jin Wang blew slightly hot water, browsing the latest papers in the field of computer security at home and abroad.

The night is dark, but the laboratory is brightly lit, most of the people have not left, can be second to none in the country, in addition to advanced equipment, and the efforts of personnel are also inseparable.

"Jin Wang, how is your graduation thesis?" asked tutor Hao Aiguo.

Hao Aiguo, director of the Jinghua Computer Department, director of the laboratory, he is still busy in the laboratory until late at night every day, Jin Wang has been studying with Hao Aiguo after being admitted to graduate school.

As he is about to graduate, his graduation thesis is naturally the top priority, and Professor Hao has always been rigorous in his academic attitude and has higher requirements for his graduate students.

Jin Wang put down the water glass and quickly opened the email, which he sent to another computer today for typesetting, which will be stored in the mailbox.

In the mailbox, an email was lying there quietly, after opening it, Jin Wang was a little surprised, the attachment should have been WORD, but now it has become a clipboard, although he was a little strange, but he still subconsciously clicked on it.

I didn't see the content of the document, but a dark red dialog box popped up, and a lot of information was written on the right side.

"One, your computer has been locked for 96 hours. ”

"Second, please pay the ...... within the time limit"

Jin Wang finally understood that this was ransomware, a kind of worm that had just become popular recently, and they were discussing how to deal with it during the meeting this morning, and this would be approached!

Seeing that he didn't speak for a long time, Hao Aiguo got up and moved twice, bypassed the experimental table by the way, and walked behind Jin Wang. The screen is red, on the left is a conspicuous countdown, more than 3 days and 23 hours, and on the right is a bright red warning.

Ransomware!

"How?" Hao Aiguo asked.

"I don't know, this should have been my revised paper. Jin Wang said nervously, faintly feeling a little bad, and cold sweat broke out on his forehead.

Oh no, the paper......

He hurriedly found the paper and downloaded it, and sure enough, the paper had been encrypted, and when he opened it again, it was full of garbled characters, not only that, but even other files in the computer were also encrypted, turning into a format that he had never seen before.

"Oh no, there's a virus on my computer. "There was just a problem here, and a girl on the other side also shouted.

"Oops, my computer too!"

There were shouts in the laboratory, and in just a few minutes, several computers were hit.

"Close the ports, update the patches, and see how many computers have problems!" Hao Aiguo's majestic voice sounded, and after a brief panic in the laboratory, the sound of crackling keyboards sounded again.

The situation quickly came up with statistics, the virus is a few public computers, usually used by everyone to download and print, browse the Internet, but neglect management, recently did not update the patch, became the source of infection.

Hao Aiguo called the laboratory manager and criticized him fiercely, as a top security laboratory, what he studied was how to prevent the invasion of the virus, and now it is good that the virus came to the door first, and it was not discovered until the outbreak of infection, which is a great shame.

"Stop what you're doing and prioritize finding a solution to the virus. Hao Aiguo's majestic voice sounded, and he said murderously.

Even in a top-level laboratory, it is not easy to crack a well-crafted virus in a short period of time.

Do you have to pay for it?

As soon as this idea came out, it was suppressed by Hao Aiguo, a top security engineer and university computer professor, who compromised with hackers, which must be the biggest joke in the industry this year!

Hao Aiguo turned on the computer, now he is mainly responsible for directional and forward-looking work, how many years have he not touched a specific job, but when his fingers touch the keyboard, the passion of his youth seems to return to his body, he glanced at the time: 11:45.

……

"Why did you just come back? The boss is going crazy again?" Tong Yu dragged his tired body back to the dormitory, and his roommates had just woken up.

Hao Aiguo's strictness is famous, and when he saw Tong Yu's dark circles, his roommates were a little distressed.

"It's none of our boss's business, the lab computer is down, my paper has been circled, and I have to change it again, hey, I have to make up for sleep!" Tong Yu ignored the emotion of sleeping and threw himself on the bed.

The chatter was getting farther and farther away, but Tong Yu couldn't sleep, she flipped out her mobile phone, only to find that the laboratory group had exploded.

I don't know who told me about the lab down, the group is all in the security field, and they don't care about the dead of night, they express their opinions and discuss them all night.

"Is the lab patched?"

"Awesome, my room, use yourself as an experimental field, this is the rhythm of superpower!"

"There is pressure to be motivated, and the younger students are cheering. ”

There are a lot of people in the group, and almost all of the people who graduated from the lab are in the group.

"Okay, if you have any good ideas or hear of any solutions, you can bring them up and discuss them. ”

"Who can have my sorrow, my dormitory computer is also poisoned, and I can't find my graduation thesis, so I want GG!" In the group, Jin Wang suddenly interjected, he now wants to die, if it goes on like this, it is a small matter to lose documents, and it is impossible to graduate or not.

There was another group of people comforting him, but there was nothing good for anyone to do.

"If you really can't do it, just pay the ransom and avoid disaster. ”

As soon as these words came out, the group suddenly fell silent. They are all engaged in computer security, and they are so pressured by hackers that they have to pay money to redeem files, which is like a fish in the throat and difficult to swallow.

They weren't the only ones who stayed up all night, as did the Aegis engineers.

For several days in a row, they were busy until late at night, and it was no longer a problem to detect and kill viruses, but it was still far from recovering the locked files.

At this stage, the best way is to prevent it, close the shared ports, and update the system patches.

After a busy night, Hao Aiguo finally confirmed that this is not a problem that can be solved in a short time, but fortunately, he is not the only one in this field.

"Hey, Lao Chen, the worm that broke out recently, yes, it's the ransomware virus, do you have any new progress?"

"Not yet, I've been busy for a few days, and I don't have a clue, this time the virus is very hidden, and the method is very special. On the other end of the phone, the voice was a little helpless, "Your Jinghua technology has always been the most cutting-edge, is there any good news?"

"Like you, there's not much progress for the time being. Hao Aiguo snorted, perfunctory, and his face turned unnaturally red.

"Professor Wang, do you have any updates on the ransomware virus?" Hao Aiguo hesitated, and then dialed the phone number of his classmates who were far away in Chongyang, at this time, they should be late at night, and they also did not rest.

"Why do you have time to call me?" a mocking voice rang out on the other end of the phone, "The recent large-scale outbreak? No, there is no real progress." ”

"There's no way to recover the files, if you want to get the documents back, you can only pay as required for the time being, otherwise when the time comes, the documents will be permanently sealed, and I already have two computers turned into bricks!"

"Yes, the encryption method is very special, very tricky, if you make progress, don't be stingy!"

There are always traces of ordinary viruses, but this time ......

There is another way, which is to crack it by force!

According to the complexity of the virus, it may take tens of thousands of years to use an ordinary computer, and even if it is a supercomputer, it will take more than a year, Hao Aiguo stared at the computer and gradually fell into deep thought.
