"Mr. Qin, you're back!"
At Ya Qin Network, on the eighteenth floor of Jiangcheng Guojin Center.
As soon as Qin Xuan entered, he was pulled into the work area by a frantic Li Hao.
Zhu Sheng and Li Yunlong were frantically operating on their computers.
If Qin Xuan hadn't spoken first, they wouldn't have noticed his arrival!
"Lao Qin, there's a huge problem!"
"All data related to Douyin, including the program and source code, has vanished. Even the backups I saved online have been deleted."
"The major app stores are all urging us to submit the app. If we don't submit it in time, we absolutely won't be able to launch tomorrow afternoon!"
Qin Xuan patted Li Yunlong's shoulder to calm him down and then asked with a frown, "Any leads?"
"Did you find anything in the computer's edit logs or surveillance cameras?"
Zhu Sheng replied bitterly, "Nothing."
"The perpetrator seems to have used a Trojan horse to turn the company's computers into zombies, and then remotely controlled them to delete all the data."
"It's just that..."
Zhu Sheng trailed off, lowering his voice.
"It's just that all this data was encrypted, especially the backups, which were password-protected."
"So I suspect the person who did this is likely one of our own."
Hearing this, Qin Xuan fell silent.
Although Ya Qin was now a large company with over a hundred employees, no outsiders had ever joined the Douyin project team.
This meant that the person who deleted the data using a Trojan horse was likely a former colleague with whom he had a good relationship.
The feeling of being betrayed made Qin Xuan feel terrible.
However, no matter what, the top priority now was to submit the Douyin software for review as soon as possible.
This was an excellent opportunity for promotion, and Qin Xuan did not want to miss it.
"How long does the software store review process usually take?" Qin Xuan asked Zhu Sheng calmly, glancing at the time.
Zhu Sheng answered without hesitation, "We originally discussed a 24-hour review period. Later, after they knew you were the behind-the-scenes boss of Ya Qin, the major app stores uniformly shortened it to 18 hours."
Qin Xuan nodded. "It's too late to start over. Now we can only hope that the person who deleted the data left a backdoor while destroying it."
"It's 5 PM now, and there are still 7 hours left until the deadline for the review."
"How about this, Lao Li, get up and let Mengqi come."
Hearing Qin Xuan's arrangement, Li Yunlong quickly stood up.
He turned his head and realized that four top beauties were standing elegantly beside Qin Xuan.
Mengqi, whom Qin Xuan mentioned, stood at the forefront, her face like frost, sending a chill down one's spine.
"Uh, Lao Qin, are these four young generals really your subordinates?"
Recalling the identities of the four, Li Yunlong's tone softened considerably.
Qin Xuan smiled and nodded, explaining to him, "Once a military rank reaches a certain level, one will have their own subordinates."
"These four are assigned to me by the country."
"Mengqi is my secretary, responsible for my daily life and decision-making, and she is also a top hacker."
"Therefore, I hope Mengqi can find the person who destroyed the data by tracing clues left in the computer."
"Only in this way can we possibly make it in time for tomorrow's live broadcast."
Li Yunlong nodded gently upon hearing this, while Qin Xuan activated his ability towards the computer.
"Computer, what do you think of what Lao Li and the others said?"
The computer remained silent for a moment before giving its answer.
Computer: The perpetrator did indeed control it remotely. A Trojan horse virus was implanted within me, and before the network was disconnected, all your actions were under the perpetrator's control.
"Are there any clues that can help us quickly identify the perpetrator?"
Computer: Yes. The Trojan horse virus was implanted by the perpetrator through the internal network. The IP address is that of the computer at workstation number four. However, the remote operation was not performed by him; the specific IP address is specially encrypted.
Hearing the computer's reply, Qin Xuan looked up at Zhao Ming, who was full of tension.
The workstation number four mentioned by the computer belonged to him.
At first, Qin Xuan thought Zhao Ming was so nervous and sweating profusely because of the lost project.
But now it seemed he was afraid of being discovered.
"How is it, Mengqi, is it going smoothly?"
After instructing the other office staff to rest in the next room, Qin Xuan approached Yuan Mengqi again.
Yuan Mengqi was staring calmly at the computer screen, her eyes scanning rapidly, like a precision instrument.
"I need to first screen the specific location of the Trojan horse."
"Then, through decryption and reverse tracking, I can determine the implantation IP and operation IP."
"However, there are too many files in the computer, and the screening process may take several hours."
Several hours?
Qin Xuan shook his head slightly.
Just the screening would take several hours, and the computer also said the operator's IP was encrypted.
If you add up all the time, wouldn't it take several hours?
They didn't have time now; they had to speed up the overall progress.
As for the method...
Naturally, it was to ask the computer again.
"Computer, do you know where the Trojan horse was implanted?"
Computer: Yes, it's on a hidden program at the very bottom of the files on the F drive.
Upon hearing this, Qin Xuan immediately relayed the information to Yuan Mengqi.
Although Yuan Mengqi was surprised, she still proceeded to screen the location as Qin Xuan had instructed. Finally, she found a Trojan horse program named 0cxf00.
"General, I found it!"
Yuan Mengqi shouted to Qin Xuan, then immediately took out a USB drive and switched the computer to another operating system.
After a series of operations that Qin Xuan couldn't quite understand, an IP address appeared before them.
Yuan Mengqi used search and location to finally determine the detailed location of the IP address.
It was Zhao Ming's workstation number four.
Just as the computer had said.
"General, this is the implantation address of the Trojan horse. It seems that a company employee was also involved in this incident."
"As for the remote control address, the perpetrator has encrypted it specially, and I will need a few more hours to decrypt it."
"It's okay, just decrypt it."
"Don't feel pressured. At worst, Douyin can be delayed for a few more months."
Yuan Mengqi nodded and resumed her intense decryption work.
Qin Xuan also slowly walked out of the office area and went to the lounge where everyone was resting.
"Lao Qin, why are you out here?"
"Did you find the source of the Trojan horse?"
Hearing the door open, Li Yunlong was the first to get out of bed.
Although Qin Xuan felt bad about them working overtime and told them to rest first, how many people could truly sleep soundly after such an incident?
Qin Xuan did not answer Li Yunlong's question immediately.
Instead, he focused his gaze on Zhao Ming in the corner.
"No."
"The virus is too complex, and Mengqi is still cracking it."
"By the way, Lao Zhao, your wife is here. Did you tell her you were working overtime?"
"She's waiting in the office right now. You should go and see her!"
