Desperate Hacker

Chapter 128 Weighing people’s hearts
Lin'an...a big data center!
Chen Qingfeng and Zhao Changan arrived here in a car with Ding Jiancheng!

Chen Qingfeng really didn't expect that Ding Jiancheng would actually bring him here?

There’s not even a sign here!
Only after walking in did I realize that there was a signboard for the Big Data Center.

But what big data center?
It’s not written at all outside.

As soon as they reached the door, the armed police soldiers standing guard in front of the door immediately stopped them!

Then Ding Jiancheng showed his ID, and then the other party made a phone call, and then printed a receipt from a small thermal paper printer at the guard post!
"Give me this note when you come out. It must be signed by the receptionist!"

"Good talk!"

Ding Jiancheng stuffed the note into his pocket.

Then he walked in with Chen Qingfeng and Zhao Changan.

"Where is this place?"

Zhao Changan asked curiously.

Ding Jiancheng looked at Zhao Changan, and then said lightly: "Secret unit!"

Zhao Changan stopped talking now.

Chen Qingfeng could only follow them into the elevator honestly!

After the elevator opened, Zhao Zhengan led him to an office location, where someone was already waiting.

"Captain Ding!"

"Old Xu, you asked me to help you find some knowledgeable people to come over. I have a lot of college classmates, but there are really not many knowledgeable people. No, I have brought them to you!"

"Hello, hello!"

Lao Xu brought Chen Qingfeng and the three of them to the office without introducing himself.

Then just after sitting down, Lao Xu poured them a glass of water, and then said with a sad face:

"These are all technical experts! The people introduced by Captain Ding are definitely worth mentioning! To be honest, we have encountered some trouble..."

"What's the trouble?"

"How should I put it? Recently, our security engineers have discovered that there are always some inexplicable data transmissions! However, the people from the security engineering have looked at it and can't see anything wrong at all! So we contacted the Public Security Bureau Comrade, I originally thought that the Internet Security Detachment would come over to take a look, but who knew that it was Captain Ding from the Criminal Police Brigade who came?"

Lao Xu seemed strange about this matter, but Ding Jiancheng did not explain it.

He simply said to Chen Qingfeng:

"The experts in our team said that the virus they have here is very similar to the virus code we found in an industrial computer at a crime scene! Brother, can you help them take a look?"

Chen Qingfeng's heart skipped a beat when he heard this.

It seems that this is a test for myself.

If you solve this problem by yourself, it means that the virus on the public computer is probably related to you.

If it can't be solved, then Ding Jiancheng will probably not ask for help from him in the future.

Naturally, there is no way to obtain information about the case.

"Okay!"

Although hesitant, Chen Qingfeng readily agreed.

"Okay! I'll arrange for two of them to go to the computer room, and I'm afraid I'll have to keep the other two's mobile phones!"

Chen Qingfeng and Zhao Changan nodded immediately!
Then they handed over their mobile phones!
In this way, the mobile phone was locked into the electromagnetic shielding cabinet.

Then the two left the office and were taken into a clean place.

There are many engineers here who are busy in front of computers.

Separated by a wall in the computer room, there are neat rows of cabinets.

The muteness here is very good. Although it is only separated by a layer of glass, the noisy sounds inside cannot be heard here at all.Chen Qingfeng and Zhao Changan were brought to a table, and Lao Xu helped them open the computer.

Then Chen Qingfeng and Zhao Changan began to check step by step.

Since it involved some business-level things, Chen Qingfeng inevitably searched the database here.

Then he unexpectedly discovered that this seemed to be a data center that processed biological or medical information!

But Chen Qingfeng is not interested in these data, although he knows that these data are valuable!But Chen Qingfeng didn't have these evil thoughts.

He experimented a little bit, and sure enough, he quickly discovered something he was familiar with.

This thing is a variant of another branch of flame, and it uses two zero-day vulnerabilities that Chen Qingfeng obtained before!

The specific situation is probably like this. Someone lurked a worm program in, and then split the data and slowly spread it out through two zero-day vulnerabilities!

Chen Qingfeng figured out their problem, but he hesitated to speak out.

"How about brother?"

"Ah! I'm still looking!"

Chen Qingfeng deliberately prevaricated, but Zhao Changan sat next to him at this time.

After staying with Chen Qingfeng for a long time, Zhao Changan actually learned something.

He looked at the logs printed on Chen Qingfeng's interface, and soon his eyes met.

Do you want to say it or not?
Chen Qingfeng recalled every scene from when he came in until now.

The armed police soldiers who were guarding this place when they came in.

There is also the scene where I put my mobile phone into a shielding cabinet before.

Everything shows that this is a high-level confidentiality unit.

Ding Jiancheng, on the other hand, felt that the cost was a bit high when he brought himself to a unit of this level for testing.

If he really came to fish, why not just take him somewhere that didn't look so strict?

So in a moment, Chen Qingfeng suddenly thought clearly.

This is not probing!
This is when Ding Jiancheng is really in trouble.

So Chen Qingfeng suddenly reached out and pressed a few commands on the keyboard. Then, he opened a blank folder, and suddenly many hidden files were displayed!
"What is this? How come we haven't seen it before?"

Old Xu adjusted his glasses and leaned down to look at these strange documents.

"This is a worm. It can create its own database, encapsulate your data, and forge it into normal data packets for transmission!"

"But our data is all encrypted!"

"Yes! Their data is also encrypted...but before encryption, the data is normal! There is a loophole here. If you guessed correctly, this program you are calling is open source, right?"

Lao Xu nodded, and then said nervously:

“We can’t trust foreign products, so some projects are self-developed!”

"But you use foreign open source products, and then do you really review the code carefully?"

"This one……"

"Or let me put it this way, for the update package released by that project, did you download the code and re-examine and compile it, or did you directly compile it and use it like this?"

"I……"

Old Xu hesitated and looked at Chen Qingfeng!

Chen Qingfeng sighed in his heart, Open SSL is used all over the world, how can open source code libraries still make mistakes?What's more, what about some open source projects whose usage rate is not so high?
