As for what they discovered after they discovered it, it was still difficult for them to clean up this program, and the encryption algorithm of this program, to be honest... It's not that Jiang Yan Hai is bragging. The rules of its encryption shell were created by Electronic Warfare Program. Even if it is forcibly cracked using a supercomputer... it probably won't be possible within a few years.
And if they can't crack it, the program will delete itself directly.
Therefore, Jiang Yan Hai did not worry about the problems of his own program, and directly released his program to track all the data flows of these hackers, and he did not care about the servers responsible for calculations.
I have already fought against these hackers, and the most powerful person so far, Jiang Yan Hai, I don't know what level of strength he has, but what is clear is that his strength is indeed quite strong.
I don't know who is better than the inventor of that virus.
It was quite easy for him to retreat. He simply set his two firewall modes and set them to closed mode. In this case, the firewall would automatically lock and erase all his retreated data, and then the firewall would reside directly in the server.
When the residence time is over, it will shatter itself internally. Such a closed-mode firewall will not have any interaction with the outside world and close all ports. Of course, the hard disk where the firewall data resides will also be inaccessible, leaving only an encrypted shell that can be cracked.
Of course, if you can crack the encryption shell, you have no problem, but if you can't, then sorry, there's nothing you can do about it.
As for the problem of cracking, don't think about forced cracking. Not to mention the issue of enough time, the computing power of current supercomputers is somewhat insufficient.
And in addition, it is not just a problem that can be solved by the amount of operations. If it only relies on the amount of operations, it is not simply composed of a few digits, it must also have certain rules.
After taking care of these two, Jiang Yan Hai directly eliminated some important parts and retreated. 10 seconds after he retreated, the two firewalls instantly changed their modes, bounced back to all access modes, and then denied any form of access.
Jiang Yan Hai had already left directly. The sudden disappearance of the data flow instantly caused the opponent's attacks to swarm directly. Then the opponent's reaction was very fast and they quickly shut down these attacks.
But after the shutdown, they quickly took control of the two servers, but they couldn't find any clues. The only thing they could know was an encryption shell that denied all access.
The problem is that when they tried to crack the encryption shell, they found that they couldn't crack it no matter what. Tom Server Rental Company is a little better, here is an encryption shell.
But there is also a web page fixed outside the encryption shell of this public library, with a sentence on it.
"It was a pleasure to play against you. I look forward to our next meeting."
This sentence is written on this page in twenty-two major languages used around the world. It is estimated that anyone can understand it.
But other than that, there is nothing. Almost all hackers like to leave IDs, characteristics, etc., none of them.
It was as if this person had never appeared before, and they could not find any trace of the other party's existence in the entire server. It was as if the other party had never been here at all, except for the encryption shell left by the firewall.
"Boss, it's bad!" Leaving aside the public library, Tom Server Rental Company, a security officer said directly to his boss.
"What's wrong?" Boss Tom already had a headache. He thought the matter would last for a long time, but he didn't expect it to end so quickly. However, although it ended quickly, their losses were not small. These customers will definitely lose money this time.
Of course, it is impossible to lose money. At most, they will be provided with free server rental for a period of time. Their data will not be lost, and the other party is obviously not targeting their data.
These people should be content.
"Our server can't be solved." The employee said with tears in his eyes.
"What does it mean that it can't be solved?" Boss Tom was a little confused. Didn't he say that the other party had retreated? Why can't this be solved?
"It's like this. Our server is directly locked. But after it is locked, if we want to control some programs, we have to read the data in the relevant area. Now all the data in the relevant area cannot be read. Our system now has problems unless we give up all the data in that area." The security officer was extremely pained.
"What kind of data is that piece of data?" The boss immediately asked, stunned.
"Regarding the core data of the system, if we don't want it, the entire server will have to be remade. In that case, we must at least determine which hard disk data the other party occupies, remove the hard disk hardware first, and replace it with new hard disks. Overall, it will take a month to be unable to operate." The security officer looked ugly.
"One month?!" Boss Tom's voice suddenly raised a pitch. If he stopped for one month, how much would he lose?
The key is that no customer can afford to have their database stopped for a month. These customers will inevitably use servers from other companies. Lost customers are the most difficult to get back!
It is very difficult to re-create the server system, especially if the entire server is to be re-systemed. Most server systems need to be backed up and repaired.
"What if we just stay the way we are now?" the boss asked immediately.
"This... it can barely operate as it is now. Our customers' data will not be affected. That part of the data happens to be our company's own data, but there is no way to record our own data. And it will still affect the performance of other customers."
"No, we can't stay for a month and just keep the status quo." The boss Tom made a decision directly. He didn't care about so much. No security issues are important now. After all, it has been invaded. How can it get worse? Might as well maintain the status quo.
"Bang bang bang..." There was a knock on his office door. Before he could speak, his secretary opened the door and walked in. He said quickly, "Boss, people from the FBI are here and want to take away our server!"
"Don't even think about it!" Old Tom was like a Tom cat whose tail had been stepped on. He jumped up from the chair and rushed downstairs without thinking.
