Into Unscientific

"Network security ah"

Hear Xu Yun's question.

Gu Qunqing was silent for a few seconds, then said:

"Doctor Xu, let me ask you a question first."

"Let's not discuss Internet companies of the magnitude of BAT. Let's talk about Sanofi, which I worked for before. Guess how many times it will be hacked a year?"

"Sanofi?"

Xu Yun blinked, why does it feel like he is discussing his ex with the current one?

But soon.

He dispelled this coquettish thought to the back of his mind, and began to seriously think about Gu Qunqing's question.

Sanofi is also a well-known pharmaceutical company, and its main advantage lies in the diabetes business.

At present, it can be ranked 5-8 in the global pharmaceutical field, with an annual revenue of tens of billions of dollars, basically belonging to the first-class giants under the top echelon.

But among the world's top 500 companies, Sanofi's ranking is not high.

It fluctuates between 270-300 all year round, and occasionally breaks 250.

This kind of enterprise’s game of public opinion will definitely not be less, but its main business is not online like Internet companies, so theoretically speaking, it should not encounter many hacker attacks.

Think here.

Xu Yun thought for a while, and reported a number:

"Ten thousand times a year?"

10,000 times a year, an average of 30 times a day, should not be considered a minority.

"Five thousand times?"

Hearing Xu Yun's answer, Gu Qunqing shook his head lightly:

"Dr. Xu, you should know that OSI has a 7-layer network model. Generally, the 4 layers that are commonly used are the link layer, network layer, transport layer, and application layer. The application layer is where ordinary people are active every day. "

"Aiming at the application layer, hackers commonly use DDOS traffic attacks."

"That is to use the contract sending machine to amplify the broiler traffic, occupy the bandwidth with huge traffic, and cause the server to be paralyzed."

"This type of attack on Sanofi's headquarters alone, the number of victims every year is no less than

"2 million."

When Xu Yun heard this, his pupils shrank immediately.

2 million?

7000 times per day on average?

A company headquarters with more than 200 people around the world and whose main business is not online is subject to 7,000 attacks every day?

Seeing Xu Yun with a surprised face, Gu Qunqing smiled and said:

"An accident? In fact, this is normal. After all, although pharmaceutical companies operate in an offline production mode, all kinds of data cannot be separated from the Internet."

"For example, all kinds of experimental reports and test drug data need to use cloud inventory, and there is no way to cover them all with a local area network."

"That way, there's a basis for a cyber attack."

After finishing speaking, Gu Qunqing pointed to Xu Yun's mobile phone next to the coffee cup:

"Dr. Xu, you can look up another keyword, 'Ma Yun 1.6 billion times'."

Xu Yun picked up the phone and searched for the keywords that Gu Qunqing said.

After a while.

He frowned again:

"Holy shit, Ali gets 1.6 billion attacks a day?"

Gu Qunqing changed into a more comfortable position on the seat, and explained with a smile:

"Yes, although Ali's number is related to the characteristics of its Internet, it is enough to explain certain situations."

"Generally speaking, a Fortune 500 company suffers no less than one million DDOS traffic attacks a year."

"As for the number of TCP/TST attacks, it will be less, maybe more than ten times a day, but this kind of attack is more deadly."

"If something happens to this kind of company, in terms of the size of the top 500 companies, it will lose at least several million dollars, and the upper limit is unknown."

Xu Yun put down the phone slowly, and nodded with emotion.

He always knew that network security was important, but he didn't have a detailed and intuitive concept.

This is the first time someone has given him an accurate description from the data, which is naturally full of impact.

According to his original plan.

The company's network security is not to say that you can find some people, but it is not necessary to build a stable and scary Internet defense system.

After all, that's all the money on the books, so saving a little is a little bit.

He even plans to find a few reliable seniors to take charge of this, after all, HKUST has a lot of experts in computer science.

But now it seems.

Obviously, his plan needs to be revised.

Then he took a deep breath and looked at Gu Qunqing:

"Aaron, do you have any good recommendations for experts in cybersecurity?"

Gu Qunqing raised his eyelids and glanced at him. He seemed to be thinking about something in his heart, and finally asked:

"Dr. Xu, have you heard of Xiao Rong?"

"Little Rong?"

Xu Yun was taken aback for a moment, then blurted out:

"The one who created Liu Guang and Su Xue, one of the main players in the hacker war?"

Gu Qunqing glanced at him in surprise, he was already ready to introduce Xu Yun:

"Doctor Xu, you actually know about this?"

Xu Yun nodded heavily and said:

"Of course I know. I know an older single dog named Fisherman. He participated in this event back then!"

When talking about the history of China's Internet development, one thing has to be mentioned:

Eagle Rabbit Hacking Wars.

The background of the incident is too sensitive to repeat.

all in all.

After the incident spread, the people's sentiments were heated, and the antagonism fermented again.

The Hongmeng blew the horn at the right time, expressing that it would plant a flag on the opponent's website.

For a time, young hackers flooded into the position like a tide.

Actually.

There are two organizers of the whole event.

They are Lin Yong lion of the Hongmeng, and Wan Tao, the founder of the Huaxia Hawk Faction.

The attack started at midnight on May 1, and the commander in chief of the attack that day was "Bing'er".

At that time, the Hongmeng distributed a software called flood to each participant in the war, with a size of tens of Kb. Tens of thousands of people opened the software at the same time within the agreed time, and the middle-level personnel were responsible for launching the attack. (At that time, the ADSL dial-up network speed was dozens of Kb. Benpu and his friends were novices, and they stayed up all night with delays. I really miss it.)

In the final result, Hongke briefly won, but in fact both sides ended up losing.

be honest.

Among the more than 80,000 people who participated in the battle, 90% were amateurs with no professional knowledge, and many of them had just learned to dial-up the Internet.

But among the remaining main force, many well-known hackers emerged.

For example, lion, Wan Tao, goodwell, ice river, aullik5, lonely swordsman, and .

Little banyan.

These hackers—or red hackers—disappeared mysteriously for a few years between 2006 and 2010, and many people mentioned the confidentiality agreement later.

Then from 2012, they gradually returned to the public view.

For example, Binghe and Juanzi are married, and they are currently very active on Weibo, showing off their affection at every turn.

Another example is that aullik5 went to Alibaba and is now the chief security researcher of Alibaba Cloud.

Also, Yuange went to Penguin and is now the head of Zhanlu Lab.

Another Honker founder, Lin Yonglion, has also come back recently. He still has an account on Xiaopozhan, and occasionally does live broadcasts and so on.

As for Xiao Rong.

It is relatively low-key.

Xiaorong was born in 1972, male.

The well-known Luandao, Liuguang, Suxue, and Liuying software are all produced by him. I don’t know how many hackers regard it as a myth.

In the original offensive and defensive battle.

The slogan on the white house is Xiaorong's famous work.

It's just that he doesn't like to make high-profile appearances like Wan Tao. For a while, Xiaorong's whereabouts were even a mystery in the circle:

Some people say that he was fully recruited and is currently working at the Chinese Academy of Sciences. .

Some people said that they were poached by IBM, and it cost two to three million dollars a year.

There are even rumors that he immigrated to Gaul - the last point is especially funny, how could a passionate Chinese Hongke be a surrenderer?

However, the rumors spread on the Internet are simply unreasonable, so these rumors did not come to an end until Xiaorong himself coughed and coughed in Kidu in 2016, and the City of Abundance appeared.

Since then, the public only vaguely knew that his current life has gradually returned to ordinary life, and that myth seems to have returned to the world from the sky.

And Gu Qunqing was one of the few people who kept in touch with Xiao Rong.

Then Xu Yun paused, pondered for a moment, and asked:

"Aaron, there is no doubt about Xiaorong's ability, but he doesn't have to worry about work at all, so how could he condescend to come to my company?"

What Xu Yun said was not self-effacing.

Just look at the group of Honker hackers in the early days of Huaxia—except for the lonely swordsman Wang Xianbing and the strange dog who entered the oranges, the others are worth millions again.

It is no exaggeration to say that the main force level bosses like Xiao Rong are begged by domestic BAT to go.

Not to mention that Huadun Biotechnology has just been created, even if the product becomes popular, Xiao Rong may not be interested in it.

Hearing Xu Yun's words, Gu Qunqing suddenly laughed.

He took out his mobile phone, clicked on Moments, swiped a few times, and then handed the screen to Xu Yun.

Xu Yun took the phone and looked at it.

I found out that this was a circle of friends just posted two days ago, and the note was 'Brother Rong':

"(Angry emoticon package) When will cockroaches be extinct? If someone can exterminate cockroaches, I will give him five years of free work!!!!"

Seeing this, Xu Yun was slightly taken aback.

Then he raised his head and cast a searching look at Gu Qunqing:

".This is?"

Gu Qunqing spread his hands towards him, affirming:

"As you can see, Dr. Xu, Brother Rong is also a cockroach hater."

two days later.

Yangcheng.

Baiyun International Airport.

Side by side, Xu Yun and Gu Qunqing walked out of the terminal slowly dragging their suitcases.

Feeling the relatively warmer temperature in Yangcheng, Gu Qunqing took out his mobile phone and looked at the itinerary.

Then he smiled and said to Xu Yun:

"Dr. Xu, you have to hire an assistant quickly, otherwise I won't have time to help you plan the schedule when the company gets on the right track in the future."

Xu Yun nodded slightly.

Like public relations, when it comes to assistants—especially the position of life assistants, many people will subconsciously rely on the word "Xiaomi".

But in fact.

In a mature company system, life assistant is actually a formal and indispensable position.

Whether it is meeting arrangements, internal reports or business trips, a qualified assistant can save a lot of things.

For example, Xu Yun and Gu Qunqing's business trip this time.

without an assistant.

Gu Qunqing handled the whole process from the taxi to the airport from HKUST, the boarding after the security check, the pick-up after landing and even the hotel accommodation.

Especially accommodation matters.

If it's a private trip, it's okay to say, Xu Yun himself is not very hypocritical, and he doesn't have to be in a high-end hotel.

You can live in four seasons for 3,000 yuan, and you can live in all seasons for 300 yuan.

But he came here for Xiaorong this time, and he needs to consider the perception problem-you came all the way to be a headhunter, and when you met, you said that I live in Hanting, so it's strange that things work out.

Therefore, out of appearance considerations, he discussed with Gu Qunqing again and again, and finally chose the executive double room at the Rosewood Hotel in Yangcheng.

During the period, the executive lounge or even the lounge meeting room may be used. In detail, there are many handover links that must be considered. It is really tiring to not have an assistant.

Not to mention that there are arrangements for meals and the like, anyway, when Xu Yun searched for reviews by himself before departure, he was almost in a daze.

Afterwards, he secretly kept the matter of the assistant in his heart, took Gu Qunqing to find a taxi, and drove to the reserved hotel.

An hour and a half later.

Taxi arrives outside the hotel door.

Another half hour passed.

Xu Yun and Xu Yun, who had completed the check-in matters, did not rest, but went out to buy some gifts first, and took a taxi again to Dongfang Wende Plaza.

After arriving at Oriental Wende Square.

Gu Qunqing took Xu Yun around and turned around until they arrived at the gate of a fairly decent neighborhood.

Only at this moment.

There is already a middle-aged man standing outside the gate of the community?

This person is about forty years old, wearing a pair of gold-rimmed glasses, giving the impression of being refined, with thick hair, he looks like a university professor.

"Brother Rong!"

After seeing this person, Gu Qunqing quickly waved to him.

Then he quickened his pace and came to the front, and gave the other party a big hug:

"Brother Rong, long time no see!"

It is clear.

This person is the famous Xiao Rong.

Xiao Rong patted Gu Qunqing's shoulder with a smile, and said with emotion:

"It's been a long time. It's been five or six years. How time flies. Everyone calls me Lao Rong now, ha!"

Then he looked at Xu Yun and stretched out his hand:

"I think this is Dr. Xu. Hello, I'm Guo Rong. I'm an idiot. You can call me Brother Rong or Uncle Rong."

Xu Yun quickly shook hands with him, and said reverently:

"Brother Rong, I'm Xu Yun, you can just call me Xiao Xu."

Although Xu Yun is a computer novice through and through, this does not prevent him from having a deep admiration for those early hackers.

In the early days when Internet-related awareness and even laws and regulations were relatively vague, they did not rely on their own abilities to act mischievously, but instead used their blood and heart to fight for the country.

In the past 20 years, only two of the more than 60 main members whose identities were exposed have immigrated, which is enough to reflect their awareness.

This is a group of truly respectable predecessors.

They may not be fighters, but they are real 'knights'.

The iteration of the Internet and the offensive of gold and yuan have not corrupted their hearts. Time flies, and they are still guarding the flame in their hearts in an unknown field.

There is a saying that is very good.

You can't see the darkness because someone is trying so hard to keep it from you.

Seeing Xu Yun's sincere gaze, Xiaorong was suddenly in a daze——Xu Yun's gaze reminded him of his former self, Binghe, and Goodwell

They were so young back then, so high-spirited.

Staying overnight in a rented house with the national flag in Jinling for several days, broke through one block after another.

In the end, as an ordinary person with countless online names, he uttered that roar on a hegemonic portal:

“China has atom bomb too!!”
