Liu Xiao couldn't figure out Estonia's practice of defining hacker attacks as military acts, doesn't this mean that Estonia was not attacked by a network this time, but suffered a military invasion? This is also a bit too unacceptable, Liu Xiao looked at Will with an incredulous expression.

Will smiled and said: "In fact, it is not news to define a cyber attack as a military act, NATO has discussed this topic for a long time, but there has been no specific conclusion, because it is difficult for them to develop a relevant standard." ”

After speaking, Will saw that Liu Xiao didn't seem to understand this, so he explained: "For example, in the Gulf War that year, Iraq purchased a very advanced air defense system from France, and as a result, the chip on the printer of this system was secretly replaced by American agents, and the US military later used radio waves to activate the virus on the chip before launching an air strike, causing the Iraqi air defense system to be paralyzed instantly, thus ensuring the smooth progress of the US air raid and destroying Iraq's air power in one fell swoop. Similarly, in the later Kosovo War, both Yugoslavia and NATO used the same means to launch cyber attacks, release viruses, and paralyze the other side's command system, which is also cyber warfare and military behavior. There is no problem at all with the characterization of these two cyber attacks, because the two sides of the war were in a state of war at that time, and the means used in the state of war were military acts. But the problem now is that cyber attacks come from the shadows, and it is quite difficult to obtain evidence, and besides, not all countries that have suffered cyber attacks have a war opponent, so ...... , huh!"

Liu Xiao now understood, in fact, he already knew these things, but he had always looked at it as a story before, and now let Will say this, think about it, it's really like this, not all cyber attacks are the same, but it is not so easy to characterize cyber attacks as military operations. It is estimated that this proposal of the Estonian ZF will have to be abandoned in the end.

It seems that he is a little unfounded, Liu Xiao smiled, "I understand, it seems that I need to pay more attention to this aspect in the future, Mr. Will seems to be very expert in this aspect!", in fact, Liu Xiao just doesn't want things to make a big deal again, if it really rises to military action, it will not only be Estonia that will suffer.

"It's nothing, if Mr. Liu also often deals with ZF officials, he will have to reverse his thinking!" Will smiled, looking helpless.

Liu Xiao sighed and said with a smile: "Estonia is so impatient this time, it seems that the loss is really great!"

"Yes, the more developed the informatization, the greater the loss when it suffers from a cyber attack!" Will nodded, "Estonia has always suffered dumb losses in this regard, and now it is estimated that it doesn't want to be dumb anymore, so it will take the initiative to make this proposal!" But this is also no way, the damage caused by this attack is too great, up to now, the order in Estonia is still in chaos, people are uneasy, there are complaints and rumors everywhere, if Estonia ZF does not behave stronger, on the one hand, it will not be able to account for the people in the country, and on the other hand, it will not guarantee that similar incidents will not happen in the future!"

Liu Xiao frowned and sighed: "Although my profession is to do network security, but I still do underestimate the power of network attacks, it seems that after I go back, it is necessary for me to ask the soft alliance to reopen a research project, hoping to find a better solution, instead of starting to think about whether to characterize it as a military act as soon as a cyber attack occurs, this kind of thinking continues, I'm afraid it will not be a good thing for anyone!"

Will nodded, "Of course it's for the best. Will looked at his watch after speaking, "It's time to eat, let's eat first, I think if things go well, Mr. Liu should be able to return to China soon!"

Liu Xiao smiled, "That's the best thing!"

After the Estonian ZF issued an initiative to NATO, NATO military officials rushed to Estonia as soon as possible, although the military official said that it is difficult to characterize cyber attacks, and it is basically impossible to prove that Russia has launched a cyber war against Estonia. But the move still caused a global shock, and various media rushed to Tallinn, the capital of Estonia, to learn about the progress of the incident and the ins and outs of the incident.

The Russian spokesman said that the cyber systems of countries around the world today have suffered similar cyber attacks to a greater or lesser extent, and he warned the Estonian ZF that when accusing Russia of launching an attack, it is best to have accurate information and conclusive evidence! Finally, he also said that the Russian side is also actively searching for evidence related to the Estonian ZF in the previous attacks.

Even if these two ZFs soared, no one wanted to suffer a loss in words, Estonia blamed Russia, and Russia immediately blamed Estonia in turn, and the two sides were very happy.

The most terrible thing is that every time the two sides soar, the attack on their network will be greater, but the subsequent attacks are obviously not as uniform as at the beginning.

After Liu Xiao finished eating, he has been surfing the Internet in his room, paying attention to the progress of things, but unfortunately the quality of the Internet in Estonia is extremely bad.

Early the next morning, Liu Xiao received a call from Hillar, saying that he asked Liu Xiao to come over and have something to discuss. Liu Xiao put down the phone, hurriedly cleaned up, and went out to the computer response center in Estonia.

It was still Hillar's office last time, Liu Xiao knocked on the door and went in, seeing that Hillar had completely lost the bearing and demeanor he had when he saw him here last time, and there were two words written on his face, tired.

"Mr. Liu, please take a seat!" Hillar saw Liu Xiao, so he put down what he was doing and came over to sit on the sofa with Liu Xiao.

"Mr. Hillar called me over, I don't know what's the matter?" Liu Xiao asked.

"We have counted the specific list of books that need to be ordered for your products, a total of more than 1,800 sets, I have reported this number to the ZF procurement department, and it is estimated that it will be approved soon. Hillar looked at Liu Xiao, "I want to know, if we place an order, how long will it take for you to hand over the product to us?"

Liu Xiao was overjoyed, this time the soft alliance can make money, his offer to Estonia is a set of 30,000 US dollars, so calculated, the soft alliance can receive more than 50 million US dollars at once, the money invested by Boss Xiong can be said to be recovered at once, "The order to the company, it should be made in one working day, and it will not take more than forty-eight hours to hand it over to you!", Liu Xiao's tone of voice could not hide the excitement in his heart.

"That's good!" Hillar nodded, "Your product has helped me a lot this time, and we can barely save some face by relying on that firewall." ”

"Mr. Hillar has won the award, mainly because your computer response center handled it properly!" Liu Xiao said politely, and then remembered something, and said: "I also want to thank Hillar for the reminder last time, if it wasn't for your reminder, I would definitely be in big trouble now, and now look at the development of things to this point, I myself feel that it was so mysterious at that time." ”

Hillar waved his hand, "You're our guest, you're here, and I'm not going to let you get involved in this." ”

Liu Xiao thanked again and again, and said: "In this way, I will give you an additional 1,800 sets of professional anti-intrusion and anti-spypping systems, which is my little gratitude to you!"

"Oh?" Hillar's tired eyes shone brightly, "Is this the system the one shown at the Black Hat Conference?"

"The Black Hat conference is showing a beginner version, and this professional version is even better than that version in terms of performance, and when used with our firewall, it can definitely greatly improve the security of your network. Liu Xiao smiled.

Hillar came to his senses and said, "Originally, I wanted to say a few words, but now it seems that I can only thank Mr. Liu, because I am very interested in your system!"

Liu Xiao said with a smile: "I came to bring a set this time, I will send it to you when I go back, if there is no problem after testing, I will let the company hand over to you along with the 1800 sets of firewall programs!"

"Thank you so much!" Hillar looked at Liu Xiao, "After this incident, the president asked us to strengthen the country's critical network, and with your products, everything is much easier!"

Liu Xiao let out an "oh" and said, "What is the point of development now?

Hillar sighed, "The attacks haven't stopped, but the intensity has slowed down, and I guess the botnet they rented is starting to partially expire." But the overall attack intensity has not been reduced, some civilian hacker organizations have begun to get involved, you know, Russian hackers are very powerful, and the number is quite amazing!"

"Then what are you going to do?" Liu Xiao looked at Hillar, Liu Xiao also had a headache for Russian hackers, "It's not a way to hold on so hard!"

Hillar shook his head, "It won't be hard, everything that should be made has already been made, and the mission of the Estonian network has been completed, and in two hours, we will cut off the network link between Estonia and the outside world again, and carry out comprehensive network repair and transformation!"

"Huh?" Liu Xiao was very surprised, Hillar's words made him a little puzzled, what is the name of the trouble, and what is the mission of the Estonian network, is there still a mystery in this, is there any other purpose for Estonia to open the network at the risk of suffering greater losses? Hillar has something to say.

"Hehe, it can be seen that Mr. Liu is a pure businessman. Hillar smiled, "Even if you are engaged in cybersecurity, you are not very clear about the direction of some things in this ***!"

"What's the matter?" Liu Xiao wondered.

"Hehe!" Hillar smiled, "Is there any website in the world that has not been attacked by the network? At the beginning, the function of the network was very limited, and if it was attacked, the loss would not be very large, but now the network has extended to every corner of the world, and the network has become a veritable central nervous system, which supports the normal operation of a country. In this world, is there a more direct and effective means of killing than paralyzing the opponent's central nervous system?"

Liu Xiao knew everything Hillar said, but he still didn't understand what Hillar meant.

"Take Estonia as an example, in the past three years, Estonia has suffered more than 60,000 hacker attacks every year, because Estonia is a small country, the loss will not be too large, but every year ZF also spends more than 8 billion US dollars to defend against hacker attacks, which is a lot of money for Estonia. The US defense system is attacked by hackers more than 20,000 times a year, and on average, it costs about $1.5 million to defend itself against it, and it has to pay more than $30 billion a year for it! The situation in other countries is basically the same. ”

"No! so much!" Liu Xiao couldn't help but regret when he heard this, he set the price of 30,000 US dollars, it seems that he really made a mistake, after finishing the Estonian order, he immediately raised the price, and it is estimated that no one will be too much if it costs 300,000 yuan.

Hillar thought that Liu Xiao was surprised by this amount, so he smiled and said: "No matter which zf it is, if you are asked to pay such a large amount of money for a long time, no one can stand it!"

Liu Xiao finally came back to his senses, "You mean to say that Estonia is deliberately making things bigger this time, in order to get NATO to classify cyber attacks as military acts?"

"Estonia is the only one who wants to classify cyber attacks as a military act?" Hillar said with an unpredictable smile on his face, "Doesn't the United States want to? Russia doesn't want to?"

Hillar stood up and said, " There are generally only three possibilities for hackers to attack ZF's network, first, the self-challenging behavior of a person or organization, which is now becoming less and less, on the one hand, ZF's security protection level has improved, on the other hand, ZF has strengthened legislation in this regard, hackers are busy making money, and no one will do this risky thing; second, targeted espionage for a certain interest group, this kind of behavior is sneaky, and everything that succeeds is not discovered by you; third, it is with the nature of retaliation or deterrence, There are politically motivated cyber attacks. If cyber attacks are included in the category of military operations, then when someone carries out the second and third attacks, they will carefully weigh the consequences. According to the most conservative estimates, this seemingly simple piece of paper can at least reduce the current attacks on the ZF network by 60%. ”

Liu Xiao suddenly realized, he finally understood what Hillar meant, maybe this cyber attack was just a coincidence at the beginning, an accidental event, and no one expected it. But from the moment Estonia closed the network and reopened it, it was not an accidental event, behind the decision to change the Estonian ZF, there were many interests behind the push, perhaps more accurately, everyone couldn't stand it, and needed such a thing to help everyone get out.

"In an hour, ZF will hold a press conference on this matter, and NATO military commanders will also attend, and after the press conference, the Estonian network will be shut down again, and then I can breathe a sigh of relief!" Hillar smiled and paced around the office, "But, then again, these things are not for you and me to care about, you are a businessman, as long as your products are safe, there will be a market, and I, as long as I make sure that the network in Estonia is functioning properly!" ”

Liu Xiao nodded again and again, he didn't want to get involved in these things, but when Hillar said this, he reminded him, "Mr. Hillar, I think we can have another chance to work together in the future." ”

"Oh?" Hillar looked at Liu Xiao, "Tell me about it." ”

"This trip to Estonia gave me a new idea, and I plan to open a new research project in SoftAlliance, mainly to establish a security system to prevent and resist such sudden cyber attacks, and to provide our customers with multiple sets of emergency and buffer solutions to minimize customer losses. Liu Xiao smiled, "Soft Alliance is a small enterprise, just starting out, lack of information and experience in the field, I think there should be a possibility of cooperation between us!"

"That's a good idea!" Hillar pinched his chin, "If you can really get this project done and solve the problem for a lot of people, I'll consider it." Hillar laughed after speaking, "Mr. Liu is really good at business, you will do whatever others need." ”

"No way!" Liu Xiao shrugged helplessly, "Who called me a businessman!"

"Okay, I'll think about this matter first, and I'll give you an answer as soon as there is a result!" Hillar replied happily.

"Okay, then I won't bother Mr. Hillar!" Liu Xiao got up and said goodbye, "In the future, when I have the opportunity, I will ask Hillar for advice again, talk to you, and let me know a lot." ”

Hillar shook his head with a smile and sent Liu Xiao out of the office.

An hour later, Estonia's press conference took place, and the world's most influential media gathered to know the final verdict on the Estonian ZF and NATO. A number of media outlets have activated satellites to broadcast the press conference live because it is so important.

The spokesman of the Estonian ZF first reported the course of the incident, he did not qualify, but in chronological order, the story of the incident was narrated, although this is only an official statement, but it is also thrilling to hear everyone, the two countries back and forth pinch, it is enough to shock everyone, plus some twists and turns in the middle, the reporters on the scene, all have a feeling of listening to a book.

Finally, a spokesman for the Estonian ZF said: "The attack was caused by the relocation of the monument to the Soviet army, and the Estonian ZF has reason to believe that the matter is related to Russia, and there is also some evidence that the person who attacked the Estonian network was supported by unknown funds, and before the incident, some Russian-language hacker chat rooms had mentioned something like 'attacking the Estonian network'." ”

The reporters immediately asked, but the Estonian ZF did not show the relevant evidence to the media.

The reporters let go of the Estonian ZF spokesman and began to ask NATO military officials: "Does NATO believe that the attack was launched by Russia, and will it take countermeasures?"

NATO's military official is very sophisticated, saying: "It should be said that this incident is the first real cyber war so far, as for who started the war, it is still difficult to say, anyone is possible, but it is not necessarily Russia, maybe just a person, or a hacker group, which requires our further investigation and verification." ”

"In other words, has NATO already determined that this incident was a military act?" the reporter continued to ask.

"At present, there is no clear international standard for defining cyber warfare, and NATO has not classified cyber attacks as military acts before, but the incident that happened in Estonia has shown us that cyber warfare has become a new type of attack method, and this kind of means will cause real harm to our security! For the sake of the people's security interests, I would suggest that NATO start work in this regard and strive to introduce a set of standards that clearly demarcate cyber warfare!"

Hillar also attended the press conference, and when he was asked by reporters for his opinion on the matter, Hillar said a very classic sentence that later became the standard for everyone's answer, "I'm just a security person, I know a lot about computers, but I don't know a lot about bigger issues, but some people like to make a fuss about these things!"

Hillar's words seem to mean that he doesn't know anything, but in fact he is warning those media people not to talk about right and wrong.

"Then ask a question about security!" shouted someone in the crowd of reporters, "As far as we know, in this cyber attack, all the networks in Estonia, including ZF, media, banks, communications, and large companies, were all paralyzed, but only one ZF sub-public website did not have any problems, is the security standard of this sub-website higher than that of the president's website, or is the opponent deliberately showing mercy, what is your explanation for this matter?"

The reporter's words are usually not clear, but everyone understands what he means, this reporter, he suspects that this incident is a joint show of the offensive and defensive sides!
