(Thanks to the book friend for illegal entry in 1987, the young empire for the reward, ZZZang.) I wish you a happy new year and good health. )

Kim Woo-sung dialed the phone of Executive Director Park Bong-sik as quickly as possible and succinctly reported to him what had happened, Park Bong-sik was furious and cursed the hackers for being unscrupulous and the IBM outsourcing team for being incompetent, and finally even Kim Woo-sung scolded him.

Kim You-sung held back the anger in his heart and shouted: "Director Park, the key is to solve the problem now, otherwise the consequences of continuing to attack our network system will be unimaginable, as the unknown hacker said." ”

"Cyber security is the responsibility of your IT department, and now that the system has been hacked, you and I have to spend money to buy safety, and the company supports you all for leisure. I don't care what you do, you must ensure the security of the network system, anyway, the company will not compromise with shameless hackers. ”

Director Park's refusal was already expected by Kim You-sung, and he had no temper when he was scolded by the head, and what he prayed now was that the unidentified hackers would not play too big.

Li Kaiwen didn't want to make a big deal out of it, but if he didn't make a big deal and couldn't collect a small amount of money, he forced him to be ruthless, and they would not give in and compromise if they didn't hurt the Agricultural Cooperative Bank.

"Hmph, the tiger is not powerful, you and I are HelloKitty. ”

Li Kaiwen snorted heavily and began to launch the second phase of the attack plan, before the guò system vulnerability deleted the credit card transaction records of the banking network was just a simple warning, now he is going to use the superRoot supreme privilege, this is a big killer weapon with supreme domination over the entire Nonghyup bank network.

Jin Youcheng hurried back to the hangar of the bank headquarters, and the first thing he said was to ask, "How is the situation?"

The deputy director in charge of the IT department on duty reported: "The damaged number of jù is being restored through the guò backup file, and IBM claims that the other party has invaded the network through the guò system vulnerability, and has now begun to repair it." Overall, the situation is manageable. ”

Is the situation under control, Jin Youcheng doesn't dare to be negligent, since the hacker who talked to him dared to blatantly sue him, he shouldn't have a hasty intrusion.

"Raise the security alert level to the highest level and cancel all employee leave......" Before Jin Youcheng could finish speaking, his mobile phone suddenly vibrated for a moment, and then he remembered a piercing ringtone.

Jin Youcheng didn't think about it, he quickly took out his mobile phone and clicked on the message, and his face suddenly changed.

The text message is very short, with only a few letters - rm.dd.

rm.dd may not have any special meaning in the eyes of ordinary people, and some people may also think of the popular Korean variety show RuningMan, but in the language of computers, rm.dd stands for delete command, deleting all the text on the server.

rm.dd means trouble and ruin.

"Report to the director, there are three servers in the process of deleting the article. ”

"There are currently fifteen servers deleting texts. ”

"Eighty-Nine ......"

"Two hundred and sixty-one..."

"Three hundred and seventy-seven ......"

A chaotic call sounded in the computer room, and Jin Youcheng held his mobile phone in a daze, and there were a total of 553 servers in Nonghyup Bank, and the servers were almost destroyed in the past four days.

It's not an invasion, it's a war, and the text message in his hand is a naked, naked, proclamation of war.

Jin Youcheng took a deep breath and shouted, "Cut off the connection between the server that restarted the system and the outside world, and confirm how many servers are still working." ”

A staff member said timidly: "Report to the director, the server that restarted the system deleted all the text in the first wave of attacks. ”

The situation is far worse than he expected, the more severe the situation, the more you have to stay calm, Jin Youcheng silently recited a few times, took a deep breath and tried to stay calm, and shouted: "Start the relay server immediately." ”

"Reported that the relay server located in Liangcai is down and unusable. ”

Jin Youcheng's heart was cold, the secret way was not good, the other party was obviously prepared, and even the relay server was invaded.

The staff in the computer room all looked at Jin Youcheng, waiting for his instructions.

The direct consequence of the almost self-destructive deletion of 386 of the 553 servers of the Nonghyup Bank was the interruption of service at the 2,754 branches of the Nonghyup Bank across the country.

As the head of the IT department, Kim You-sung is not able to disclose the hacker statistics of Nonghyup Bank's network for the time being, and has lost most of its servers.

The only way to do this is to start the last disaster recovery server and restore all the servers, otherwise the entire network of Nonghyup Bank and nearly 5,000 business outlets will be paralyzed, which will be a fatal blow to the bank.

Jin Youcheng gritted his teeth and shouted, "Start the disaster recovery server." ”

"It was reported that the disaster recovery server located in Anseong was down and could not be started. ”

Jin Youcheng's eyes were dark, and he almost fainted.

XIBAI, THIS IS TO KILL EVERYTHING AND LEAVE NO WAY BACK.

All countermeasures were completely ineffective, and Kim Yoo-sung immediately reported to Executive Director Park Bong-sik, and at the same time ordered his subordinates to urgently contact the situation of the disaster recovery server in Anseong, the relay server located in Yangjae, and contact IBM to ask about their response plan. A large area of servers has lost their texts, and the reboot server and backup server have all failed, so reconnecting to the network is not a matter of three moments, and the worst plan is to reinstall the system to solve it.

It was not the first time that Nonghyup Bank was hacked, but it was foreseeable or the last, and Executive Director Park Bong-sik rushed back to the headquarters to listen to Kim Woo-sung's report as soon as he received the notice.

Located at the top of the executive director's office, Kim You-sung reported to Park Bong-sik the loss of the hacker attack in 1510.

"I'll just ask you when you can restore the bank network?" Park Bong-sik roared almost roaring, what bullshit was hacked and he didn't understand and didn't care at all, he was concerned with the normal operation of the bank.

A large-scale service interruption by a large commercial bank is extremely damaging to its reputation, and he absolutely cannot tolerate such a thing.

"If the relay server and the disaster recovery server can be restored, the data can be restored in as fast as three hours, if not, the server can only be reinstalled to solve the problem, it will take at least three days. ”

"Bastard. Park Bong-sik banged heavily on the workbench.

After a burst of anger, Park Bong-sik opened his mouth and asked, "Are you sure that this incident was caused by hacking?"

"Yes, it's the hacker who asked for $300,000 for a system vulnerability that day, and I received a call from him this morning," After hesitating for a while, Kim You-sung took out his mobile phone and handed it to Park Bong-sik, "Just one minute before the server deleted the text, I received a text message from the hacker. ”

"rm.dd?" Park Bong-sik, as the executive director, is not proficient in computers, and looked at Kim You-sung with a puzzled look.

"This is the highest-level system command, which can only be executed by the SuperRoot administrator with the highest privileges, and it is limited to specific IP segments of the bank's intranet," Kim explained. ”

"So the hacker got the highest authority on the banking system?"

"As it stands, it is. ”

Even if he is not computer savvy, Park Bong-sik knows what it means to get the highest privilege in the system.

The two were relatively silent, and after a while, Jin Youcheng received a report from IBM that the relay server and the disaster recovery server were attacked by the mutant "worm" virus, and they were in the process of urgently cracking the virus.

And so it was. Hanging up the phone, Jin Youcheng sighed lightly.
