Copying is a basic function of computers.
The underlying layer of the computer has the copy function. There is no need for code to achieve this function, just an execution instruction is required. However, if one uses their computer to copy data transmitted by another computer, data that has yet to be identified, the difficulty becomes a completely different matter.
Zhao Yi thought it out and created a ’hanging IP suffix’ data packet. When the data packet is attached to the information sent by the target host, the IP navigation function can be realized. This way, the information can be ’navigated’ over.
This isn’t copying - it’s interception.
The target information isn’t duplicated; it’s directly diverted elsewhere.
"Unless greater authority can be acquired, or if the target host is used for replication, accomplishing replication is difficult." freewёbnoνel.com
This isn’t something that can be solved quickly.
If the target host is used for the copying function, it’s easier by comparison but it equates to controlling the target host. The method is simple - deploy a Trojan horse program.
"To mount a Trojan horse, one must breach the interception program and avoid detection as a Trojan horse. Concealment is key but as soon as it operates, it could be detected."
"Creating havoc is easier; just create an infinite replication or run with any program..."
Zhao Yi shook his head.
Even if a Trojan horse program was created, the aim definitely isn’t to cause chaos. Actions that harm others and bring no benefit to oneself are pointless and can implicate one in grave legal issues.
The Trojan horse program to be created shouldn’t be destructive. It should also ideally have a self-destruction function...
A self-destruction function?
Zhao Yi suddenly remembered a game called Dota. It had a character called the Goblin Engineer whose ultimate ability was to commit suicide, causing a huge explosion at its location.
This way, the enemy could not gain any points, and in a situation where death was inevitable, it wasn’t a bad strategy.
"If the Trojan horse was a one-time execution, no after-effects would emerge. Even if it were detected, it wouldn’t matter given it’s a one-time operation."
"At the same time, could it fulfill multiple functions?"
Zhao Yi’s eyes lit up at the thought, and he immediately started writing the code.
If the program was a one-time execution and if the code was simple enough, embedding it into other software, programs, or documents would be extremely easy. However, it must be easy to deploy and execute, and hard to detect. Otherwise, it would be meaningless.
That’s the challenging part.
Zhao Yi decided to write using the base code. Base code can be embedded into many places and directly call to execute some basic functions of the computer to enhance the ability of its own program.
Soon.
With the abilities of the "Law of Cause and Effect" and "Connection Law," he completed a ’one-time Trojan horse framework’.
All that was left was to add functions.
Zhao Yi’s goal was to crack a police website, preferably to find the admin entrance to the site, plant the Trojan horse into the computers of the police department, and duplicate the web page’s logs. This choice wasn’t a bad one.
The implementation of this functionality was simple.
Because the same operating system is used, the default path for the browser’s history is often identical. All he needed was to use basic instructions to execute the copy function and construct a feature to send to a specific IP address.
Nonetheless, to be risk-averse, he decided to start from basics, looking for the file path first before proceeding with copying and transmission.
Transmission was much harder than replication.
To transmit, a connection must be established, and the default IP host of the Trojan horse must have a direct connection port.
Zhao Yi created a receiving program.
The program had to constantly run to receive information transmitted by the Trojan horse.
Now, the final step remained - deploying the Trojan horse program.
"Making a website infested with Trojan horses? And hide the IP address while at it, so that others can’t easily find it?"
"Or design another program?"
"No!"
Zhao Yi suddenly shook his head. His target was the police website; there was no need for such complexity.
He turned on the listening logs.
There were dozens of Penguin Number accounts and passwords. He logged into one to check, found groups related to policing, and then sent a group email with the Trojan horse document.
He logged into the second account.
"The logistics director, Zhou Hongwen?" Zhao Yi looked at it in surprise. He realized there was no need to log into the rest.
This single Penguin Number was equivalent to ten!
...
That night, Li Jiandong was working the night shift.
Compared to other departments of the police, the logistics department is relatively more laid-back. In the event of emergencies, logistics is rarely called upon, making the night shifts in logistics comparatively easier.
Despite this, Li Jiandong could not relax at all. He was worried about the police website getting hacked again, so he kept checking the opened website link, inspecting carefully for any modifications.
He continued doing this until after eleven.
"It seems to be good. There’s nothing that could be done from the other end since the management portal is hidden," he thought.
Li Jiandong breathed a sigh of relief and noticed a group email notification appearing at the bottom right corner of his screen. There was a new email in his Penguin mailbox. Usually, he wouldn’t pay much attention to these because most of them are advertisements or scams, but this one was different.
It was an email from Director Zhou.
Li Jiandong quickly opened it and found that the email contained just one line—
Everyone, please take a look at the document below!
"Document?"
Li Jiandong then realized that there was an attached document in the email. Without giving it any thought, he opened it right away. The document opened in a browser, filled with gibberish.
"What is this? Is there a problem?"
Li Jiandong messed around with it for a while but couldn’t make heads or tails of it. He even tried downloading and opening the document again, but it was still full of gibberish, "Maybe they sent the wrong document?"
Li Jiandong didn’t pay it any mind.
He graduated in computer science and has been involved in computer-related work since joining the police force, so he has a fair amount of confidence in his computer skills.
For instance, his computer’s firewall has always been kept at the highest level of protection, and the antivirus software would always be turned on.
Unless there’s an alert from the firewall or antivirus software, he wouldn’t pay extra attention to anything.
Zhao Yi had finished his grooming and was ready for bed when he scanned his computer screen and found that his program had received a message.
Someone had opened the email already?
He opened the document records, which showed hundreds of link records. The feature of the trojan horse program was that it would replicate the last 100 history link records each time it was executed.
There was a hint of net fishing to this.
Truth be told, that was what spreading a trojan horse is like—seeing how many "fishes" you could catch once the net is cast, it mainly involves luck. ƒrēewebnovel.com
Zhao Yi had specifically targeted the Penguin Number for delivery, and he was very lucky indeed. He found a few police-related links, and upon opening them, discovered the management access points.
Upon seeing the suffix of the access point, he had an epiphany.
No wonder I couldn’t find it!
The swine had modified the access point link so much that it had practically become gibberish.
Zhao Yi tried several recorded IDs and passwords, and promptly entered the management page. He then uploaded a Flash animation of an eagle soaring, added links, and hid a super challenging Mathematical Olympiad problem.
A special hint couldn’t be left out —
(The product of the answer and π is the password, good luck!)
And then...
"Right!"
"The guy has hidden the management access point. It’s not easy finding it. Would be easiest just to embed a program directly into the website’s source code!"
Zhao Yi, full of energy, began coding.
This was easy.
He hid the program in the invocation of the database, image loading, and file code. Its function was to show the link to the management entrance, and the account and password for management, on the tertiary interface of long news articles.
Of course.
The displayed information was scrambled, so other people definitely wouldn’t understand.
If a programmer, who was experienced and good at website design, saw the program invoking the database in the website code, they would probably find something amiss.
But they’d need to look very carefully.
Seeing the gibberish on the tertiary news interface wasn’t easy either—for one, few people visited it, and secondly, that particular news article was quite official and basically content-less. It was a bit of headache just looking at it, so it was unlikely anyone from the police department would even click on it.
"He won’t be able to change it again this time!"
Zhao Yi, satisfied, went to sleep. But his mind kept returning to the problem of the program design.
’I wasn’t able to accomplish ’copy surveilling’, which I find vexing. Using a trojan to find the management portal is a bit rudimentary.’
However...
’The Bomb Guy’s trojan framework is not bad; it’s highly covert, easy to deploy, lots of room for improvements, and very promising.’
That was also a gain.
