Why Are Your Names Like That?
As morning approached, Oh Han-sung and his group quietly entered a recently purchased two-story internet cafe in Gyeonggi Province.
As soon as the door was securely locked, the three people standing in the middle sat down and turned on the computers as if they had planned it. As soon as the screens lit up, they plugged in the USB drives they each had.
Oh Han-sung, who had been watching the situation from behind, approached one of them.
"How long will it take to breach it?"
The man was Yoo Dong-shik, a hacker recruited by Oh Han-sung through the dark web.
"No matter how great MH Group's system security is, it's bound to be breached with the DDoS attack we've prepared. After that, we'll give an attack fake with Looping, open the Routers, and extract the necessary data."
Next to him were Nam Min-joon and Kim Seok-hwan, who had also been recruited. They all looked curious, as if they couldn't wait to play with their toys.
"...I don't know about that stuff, just tell me how long it will take."
Yoo Dong-shik clicked his tongue.
"Tsk! Considering the scale of MH Group's servers, it'll take thirty minutes at the earliest. Even with a delay, about ten minutes more? That should be enough."
"You must not be traced."
"Don't worry. Didn't you see our skills not long ago?"
Not long ago, Yoo Dong-shik and other hackers had attacked the Ministry of National Defense's main server. The reason the Ministry of National Defense was the target for testing was simple.
They judged that even if the Ministry of National Defense was attacked by hacking, it would hide it internally if the damage wasn't significant. And as expected, there was no separate announcement even after the hacking attack was over.
Of course, it was also thanks to Yoo Dong-shik and the hackers' skills that they weren't traced.
"I thought it was good. However, this time, you need to be more careful since you have to extract all the confidential data from MH Group and MH Future Security. Especially the high-priority data."
Yoo Dong-shik smiled broadly.
"You don't have to worry about that."
Meanwhile, Oh Han-sung checked his watch and saw that there were about 15 seconds left until 9 a.m.
"Now, get ready. As I said before, the time limit is 30 minutes, and it must be finished within a 10-minute delay at the latest. Even if you can't finish it, you'll cut off all the power at that time and escape."
"Ehey∼ Don't worry, I told you."
Yoo Dong-shik and his colleagues loosened their fingers and got into position during the few seconds left.
Soon, the computer time reached 9 a.m.
Tatatatatatak―
The sound of keyboards and mice echoed loudly inside the internet cafe.
Oh Han-sung wiped the dust off a chair and sat down behind them to watch.
About five minutes passed. From the right of Yoo Dong-shik, Nam Min-joon, who was executing a DDoS attack with Zombie PCs, let out a questioning voice.
"...Huh?"
That voice was followed by Yoo Dong-shik and Kim Seok-hwan.
"...Why is it like this?"
"Why is it blocked?"
A DDoS attack is used to paralyze a server by increasing its traffic, and as it is a very simple method, it was difficult to fail.
Oh Han-sung also felt something was wrong with that reaction and got up to look at the screen.
"What's wrong?"
Yoo Dong-shik scratched his head vigorously.
"The MH Group security system is reversing our DDoS attack… Damn it!"
At that moment, Yoo Dong-shik's computer screen froze. He passed by Oh Han-sung and immediately moved to another seat.
"What's not working properly?"
"It's noisy, so wait a moment!"
Nam Min-joon and Kim Seok-hwan also moved their seats as if their computers were broken.
From then on, the three men lost their relaxed appearance and leaned into the monitor as if they were going to bury their faces in it. At the same time, they frantically typed on the keyboard and continued to pour out DDoS attacks to break through MH Group's security system.
【ERROR CODE 30020222】
【ERROR CODE 30020222】
【ERROR CODE 30020222】
.
.
But only their computers continued to suffer the backlash, not MH Group's security system.
"We have to keep attacking, so turn on all the other computers!"
Oh Han-sung, frowning, nodded to some of the bodyguards around him.
Accordingly, all the computers in the internet cafe were turned on one by one, and the hackers, including Yoo Dong-shik, moved even more busily.
"Min-joon, Seok-hwan. You two pour it out as much as possible. I'll try to get in through the Backdoor I prepared."
"Already? If you go in now, you'll get caught. Then you might get traced."
"The situation is already dangerous."
The opponent must have realized the situation just by reversing the DDoS attack.
In response, Yoo Dong-shik ran his own program and infiltrated MH Group's security system.
The command prompt screen appeared and was linked to the program, and numerous characters were automatically filled in a complex manner.
About ten more minutes passed. The character he wanted finally appeared at the end of the screen.
【Connection completed…….】
"Got it! These guys, they must have been too busy blocking the front door."
"Really? Then move quickly!"
"I'm already… Huh?"
Suddenly, the character pixels on the command prompt screen began to collapse.
Seeing that, Yoo Dong-shik felt a chill down his spine and couldn't move his fingers. No, he was unconsciously typing on the keyboard, but no keys worked.
"This bastard… what the hell?"
At that time, the completely collapsed pixels disappeared as if they were being sucked into the center of the screen. It wasn't just Yoo Dong-shik's monitor that was like that.
All the computer screens in the internet cafe that Oh Han-sung's men had just turned on changed like that.
"...This is a Blackhole virus. Why is it here……."
Oh Han-sung doesn't know much about computers, but he could guess the situation from the atmosphere and their actions.
"Did you fail?"
"……."
Yoo Dong-shik, Nam Min-joon, and Kim Seok-hwan, their once confident appearances gone, couldn't answer.
Frustrated, Oh Han-sung had no choice but to grab Yoo Dong-shik by the collar and lift him up.
"I'm asking if you failed!"
"...It's a failure."
"We're getting out of here now."
With the instruction, Oh Han-sung turned off the power to the internet cafe and led the people outside. The large van that they had come to the internet cafe in left as soon as everyone got in.
Meanwhile, Oh Han-sung looked at Yoo Dong-shik, who was sitting across from him, and asked loudly.
"What the hell happened? You clearly said you could succeed earlier?!"
"It's him."
"...Who are you talking about?"
The other two's expressions weren't good either.
Then Yoo Dong-shik parted his lips with difficulty.
"Do you know the Hacker class?"
"I know you guys are Wizard class."
"To be exact, it starts with the bottom-tier Lamer, then Script kiddie, Develop kiddie, Semi elite. And finally, there's the Elite, who is called Wizard class."
Oh Han-sung's brow furrowed even more at Yoo Dong-shik's incomprehensible explanation.
"Why are you suddenly talking about that?"
"There's one more class that hackers use to refer to those above Wizard class."
"...What is it?"
"A Creator who creates something from nothing. They're called Creators. And among us, there's a hacker who was called Creator, named Blackhole. What we saw earlier was his specialty, the Blackhole virus."
Oh Han-sung frowned even more and stared intently at Yoo Dong-shik.
"So, you're saying that the hacker named Blackhole built a firewall in MH Group's security system?"
"He didn't just defend, he even launched a counterattack! A proper one at that!"
Oh Han-sung, who had become serious, leaned back in his chair and sighed. After thinking for a moment, he asked Yoo Dong-shik again.
"Who is the hacker named Blackhole?"
"Blackhole is called a legend even on the dark web. But for some reason, he suddenly disappeared about four years ago. Rumor has it that he was caught by the CIA or Interpol, or that he was dragged to North Korea. How would I know the identity of such a person?"
Anyone who heard it would have no choice but to think it was absurd.
Oh Han-sung let out a long sigh and wondered whether to believe the words or not.
"Is there no way to find out at all?"
"There are more than one or two Crackers who have been attacked by him, so if they could have found out his identity, they wouldn't have stayed still."
"Hmm… Okay, I understand for now. I'll drop you off at your accommodation, so stay quiet for a while. Of course, I'll pay the fee I mentioned before. But you must stay without any disturbances."
It was a quiet but powerful voice.
Yoo Dong-shik and the others, who understood the meaning, quietly nodded.
.
.
.
At the same time.
In the MH Future Security CEO's office, Jang Man-soo was letting out a chilling laugh.
"Kekekekeke! Do you think you can do anything to me?"
Perhaps because he laughed while doing something busily for a while, Lillian and Wei, who were working on the other side, peeked over the partition.
"Hey, Jang Man-soo! What are you doing, laughing like a pervert? Are you really a pervert?"
"Is something good happening?"
At that question, Jang Man-soo made a satisfied expression.
"There are some pathetic guys who are trying to target MH Group's servers."
"Are you saying there was a hacking attempt?"
"Really? What happened?"
Lillian and Wei immediately got up and approached Jang Man-soo.
"I caught them all and crushed them. I even found out who they were."
"Who are they?"
"Piranha, Greenwhale, Antlion pit. Wizard class Crackers who were active on the dark web. When I traced the IP, it was Gwangju, Gyeonggi Province."
At that moment, Lillian's expression distorted.
"A fish, a mammal, and a pit? What kind of names are those?"
"Everyone usually makes them like that."
"Then what are you?"
"Me? …Blackhole."
At the answer in a small voice, Lillian and Wei squinted their eyes as if they were dumbfounded.
"Bullshit―! You're just a hole."
"Hey! That's what I use!"
"Did you get a patent? Did you register a trademark? What does it matter who uses it?"
"Tch!"
Lillian pushed Jang Man-soo, who was sulking, to the side and looked at the screen.
"Forget the weird names! Did you even find out their identities?"
"Of course. I investigated all the Wizard class hackers just in case. Well, it was difficult to put LEUCO coordinate restriction on overseas hackers, but fortunately, they were Koreans."
Jang Man-soo, who answered that way, displayed the identities of the three people.
"Yoo Dong-shik, Nam Min-joon, Kim Seok-hwan? These young bastards!"
"Yoo Dong-shik here is only one year younger than you."
"There's such a thing as mental age!"
"Yes∼ Yes∼ Grandma."
Peokeok― Kung!
At Lillian's fist, which flared up, Jang Man-soo's head fell forward and hit the keyboard. The 5, 6, 7, and 8 keycaps in the middle of the keyboard, pressed so hard, came up with Jang Man-soo's forehead.
"Ouch! That hurts! Ack! My keyboard!"
"Then do you think I'm hitting you to not hurt? Is there anything else?"
"I need to check the surrounding CCTVs too."
Jang Man-soo plugged in the keycaps he had taken off his forehead and moved his fingers busily again.
Of course, the keycap-shaped marks remained on his forehead.
Meanwhile, the screen changed and several videos appeared.
"They were determined to be someone."
"Why?"
"It's been edited."
As the video played, the vehicle seemed to teleport with subtle noise.
"Did they do it?"
"That's right. Only the CCTVs around the internet cafe's location are in this state. The same goes for the convenience store CCTV next to the internet cafe. Judging by the skill, it's Piranha Yoo Dong-shik. The source used for hacking is him. They must be hiding tightly now?"
Jang Man-soo scratched his waxed hair vigorously as if he was very sorry.
"Can't you find out?"
"If I use PTA(Polygonal Tracking Algorithm), I can try to track them even if it takes time. I need to let the boss know first, right?"
"If it's the boss, he went to the Central District Prosecutor's Office. He should be arriving soon at this time. Ah, what about the work the boss asked you to do before he left?"
"It'll start later."
Everyone let out a long sigh of relief at those words.
