Chapter 657

"Furthermore, the doors and windows are all connected to an alarm system."

"If they are forced open, the Security Department will receive an alert immediately."

"We have tested it, and the alarm system is functioning normally."

"Inside the confidential data room, no fingerprints other than those of the four people mentioned above were collected."

"In summary: we can 100% rule out the possibility of external theft!"

Pausing his words, seeing that Lin Feng had no reaction, Qin Yuhao continued.

"There are a total of five keys to the confidential data room."

"In addition to the one held by each of the four people mentioned above, the Group's General Manager, Tao Shaohua, possesses a spare key."

"We have inquired, and Tao Shaohua went to the Shanghai branch for an inspection half a month ago."

"The key is kept securely and has not been lost. Report finished."

At this moment, Lin Feng marked the key points in his notebook.

If external theft is ruled out, then the leak must come from within.

As for how many keys there are, whether they were lost or not, these are not the important parts!

Because having the key alone is far from enough.

At least three conditions must be met to successfully steal the confidential data.

First, perfect stealth to avoid being captured by surveillance cameras.

Currently, there is a type of civilian material that can reflect and shield against infrared camera recording.

Second, proficiency in advanced hacking techniques.

To invade the surveillance system without leaving a trace and perfectly modify the surveillance video.

Third, possessing the key, and having someone assist; all are indispensable.

The probability of the above three points being triggered simultaneously is slim, so it can basically be ruled out.

"Zhao Meng, what has your team discovered?"

Zhao Meng shook her head: "After inspection, the Group's internal network is a local area network."

"The confidential data room is only connected to the database."

"The network cables are buried within the walls and cannot be damaged or tapped into."

"In the network control room, we also found no external relay devices."

"Additionally, we questioned the administrator."

"Within the last week, no one has reached the network control room under any pretext or reason."

"Therefore, we can 100% rule out remote intrusion and remote copying."

Not finding anything does not mean there were no gains.

The combined results of the Qin Yuhao and Zhao Meng (cdde) teams equal one answer.

The leaker must be one, or perhaps two, of the people who appeared in the video.

An engineer plus a security officer is the most perfect combination for a leak.

In a single-person scenario, the difficulty would increase countless times over!

Lin Feng mused: "Old Qin, take some men to understand the destruction process of the confidential USB drives."

"Yes, Section Chief."

Qin Yuhao's team accepted the new order, but before they could leave—

Sun Hongwei and Xiao Bo walked into the conference room, each carrying a bag.

"It's noon, comrades, eat first."

Very well, an Emperor does not starve his soldiers; we will talk after eating.

Although Liu Nan and Zhang Jianqiu have not returned yet, we will not wait for them.

Box lunches for a simple meal; no one had any objections.

"Leader, Section Chief Xiao, have you two eaten?"

Sun Hongwei nodded: "We ate with Han Zong."

"I will speak now, you listen while you eat."

"Han Zong has used the confidential data three times within the week."

"Each time he used it, he was accompanied by one security officer and two engineer assistants."

"During the usage process, there was 100% no room for a leak."

"Because they have recently been tackling a technical problem."

"Han Zong has not been home for ten days, or rather, has not left the research institute."

"Of course, the possibility of colluding with others to leak the information cannot be ruled out."

"Additionally, to clarify: the occurrence of the leak incident has caused certain distress to the relevant researchers."

"Han Zong himself is also extremely troubled."

"He requests that we ferret out the hidden leaker as soon as possible to restore research progress."

At this moment, Xiao Bo spoke up seriously.

"Comrades, the strategic missile must be delivered to the Second Artillery Corps by the end of August."

"Therefore, every second counts; we must hurry to complete the investigation of the case."

There are no small matters in national defense; Lin Feng and the others can all understand this thoroughly.

However, handling a case requires each step to be interlinked and progress layer by layer.

When pitting one's wits against spies, being impatient won't solve the problem.

One can only try to shorten the time as much as possible while ensuring quality and quantity.

Lin Feng finished his meal in a gulp and opened his notebook.

"Leader, synthesizing the current investigation results, one answer can be reached."

"The leaker is an internal staff member."

"General Han and the other three, plus the five security officers..."

Xiao Bo interrupted in surprise: "Little Lin, why are security officers involved?"

Lin Feng said solemnly: "Anyone who has entered or exited the classified data room is a suspect."

"If we exclude General Han and the other three, then it must be a security officer who leaked the information."

"Regarding this, I hope Section Chief Xiao can have the courage to accept it."

Alright, thinking about it carefully, that is indeed the case.

As an old Party member, Xiao Bo can accept everything and also dares to take responsibility.

The next second, Lin Feng asked him: "Section Chief Xiao, I need to understand three things."

"First, when assigning security officers, was there any deliberate or intentional waiting?"

"Don't rush to answer; you need to recall carefully, and it must be the truth."

"Second, how much do you know about the five people mentioned above?"

"Third, what is your personal opinion on Mai Zirui?"

Just then, Liu Nan and Zhang Jianqiu returned.

Lin Feng signaled for them not to speak and to eat first.

After a long while, Xiao Bo shook his head: "Random assignment, I didn't feel anyone was deliberately or intentionally waiting."

"Anyone joining the group must undergo a political review by the Military Political Department."

"The Group Security Section only does a symbolic check."

"Hmm, all five people above work very seriously."

"They are earnest and sincere, never perfunctory."

"As for what the situation is after work, I am not clear."

During the conversation, Xiao Bo looked at Lin Feng.

"By specifically mentioning Mai Zirui, are you suspicious of him?"

Lin Feng shook his head: "It doesn't count as suspicion, just a focus on understanding."

"Because the number of times he appeared in the classified data room is a bit too high."

"Think about it, the Group Security Section has nearly three hundred security guards."
