As for the fact that after they found out, they found out about it, and it was still difficult for them to clean up this program, and the encryption algorithm of this program, to be honest...... It's not Jiang Yanhai bragging, just that the law of its encryption shell is made by electronic warfare programs, even if it is forcibly cracked with a supercomputer...... I don't think it will work for a few years.

And if they can't crack it, the program will delete itself.

So Jiang Yanhai didn't worry about the problem of his program, and directly released his program to track all the data flows of these hackers, and he didn't care about these servers responsible for computing.

Fighting with these hackers can be regarded as having fought each other, and Jiang Yanhai doesn't know what level his strength is because of the most powerful person who has come out so far, but it is clear that his strength is indeed quite strong.

I don't know who is better than the inventor of that virus.

It's quite simple for him to retreat, he directly set his two firewall modes to closed mode, so that this firewall will automatically lock and erase all his retreat data, and then the firewall will reside directly in the server.

When the residence time is over, it will crush itself internally, and the firewall will not interact with the outside world in such a closed mode, closing all ports, and of course, the hard disk where the firewall data is stationed cannot be accessed, leaving only an encrypted shell that can be cracked.

Of course you can crack this shell, you have no problem, but if you can't, then sorry, you can't do anything about it.

As for the problem of this cracking, don't think about it forcibly, let's not talk about whether there is enough time, the amount of computing power of the current supercomputer is not enough.

In addition, it is not only a problem that can be solved by the amount of calculation, if it only relies on the amount of calculation, it is not simply composed of how many digits, etc., it must also have a certain rule.

After getting these two, Jiang Yanhai directly eliminated some important parts of the retreat, and 10 seconds after he retreated, the two firewalls instantly changed their modes, bounced back to all access modes, and then refused any form of access.

And Jiang Yanhai had already left directly, and the suddenly disappeared data stream instantly made the opponent's attacks directly swarm, and then the other party's reaction was also very fast, and he quickly closed these attacks.

But after shutting down, they quickly took control of both servers, but they couldn't find any clues to find, the only thing they knew was an encrypted shell that denied all access.

The problem is that when they tried to crack the shell, they found that they couldn't crack it. Tom Server Rental Company is a little better, this side is an encrypted shell,

But there is also a constant web page on the outside of the public library's enclosed shell with a sentence on it.

"It was a pleasure to fight with you, and I look forward to meeting you next time."

This sentence is written on this page in twenty-two of the world's major languages, and it is estimated that anyone can read it.

But other than that, there is nothing, almost all the IDs, characteristics, etc., that hackers like to leave behind, all of them.

It's as if this person has never appeared, and they can't find any traces of the other party's existence in the entire server, as if the other party has never been here at all, except for the encryption shell left by the firewall.

"Boss, no!" The public library aside, Tom Server Rental Company, a security officer, spoke directly to his boss.

"What's wrong?" The boss Tom was already having a headache, he thought that the matter would last for a long time, but he didn't expect it to end so soon, but although it ended quickly, their losses were not small, and this time these customers would definitely lose money.

Of course, it is impossible to lose money by losing money, at most, they are provided with free server rental for a period of time, and their data is not lost or anything like that, and the other party is obviously not targeting their data.

They should be content.

"Our servers can't be unlocked." The employee said without tears.

"What does it mean that you can't solve it?" The boss Tom was a little confused, didn't he say that the other party had retreated? What's going on with this inunsolution?

"That's right, our server is directly locked, but after the lock, if we want to control some programs, we have to read the data in the relevant area, and now all the data in the relevant area cannot be read, and our system now has problems, unless we give up all the data in that area." This security officer is extremely painful.

"What's that data?" The boss was immediately stunned for a moment and asked.

"Regarding the core information of the system, if we don't want it, the whole server will have to remake the system, in that case, we must at least first determine which hard disk data is occupied by the other party, remove the hardware of these hard disks first, and replace them with new hard disks, as a whole, it will take a month to not be able to operate." The security officer's face was ugly.

"A month?!" Boss Tom's voice jerked up a pitch, how much would he lose if he stopped for a month?

The point is, no customer can afford to have their database shut down for a month, these customers will inevitably use other companies' servers, and lost customers are the most difficult to recover!

It is very difficult to rebuild the server system, especially if the entire server is rebuilt, and most of the server systems are backed up and repaired.

"What if we just keep it the way we are?" The boss immediately asked.

"This ...... It's barely possible to maintain the current situation, and our customers' data will not be affected, and that part of the data is just our company's own data, but we can't do our own data records. And there is still an impact on some of the performance of other customers. ”

"No, you can't stay for a month, just keep it as it is." Boss Tom made a decision directly, he didn't care so much, it didn't matter what security issues were now, anyway, it had been invaded, could it be worse? It's better to maintain the status quo.

"Bang bang bang......" There was a knock on his office door, and before he could speak, his secretary pushed the door directly and walked in, and said quickly: "Boss, the FBI people outside are here, saying they want to take away our server!"

"Don't think!" Old Tom jumped up from his chair like a cat whose tail had been stepped on, and rushed downstairs without thinking.
