Reborn Ace Hack

Wang Jialing didn't know that the change in wind direction had actually been brewing since ten o'clock in the evening. What he saw was just the result of the explosion after a long period of brewing.

On the evening of January 11th, Gu Lang finished his day's work and stayed in the network department as usual, paying attention to the operation of the Xuannie firewall.

At ten o'clock in the evening, the firewall suddenly sent out an alarm, which attracted everyone's attention.

"The network traffic has been in a very low state. It is obvious that a denial of service attack can be ruled out. So what exactly caused the firewall alarm?"

In order to figure out this situation, Gu Lang opened the firewall log, only to find that someone was scanning the open ports of the server and trying to access an open port of the server. The reason why the firewall alarmed was because of this person who was trying to attack.

The method used is somewhat different, and the data packet requesting the service is so different that it is difficult for the firewall to determine whether the request is a normal request or a malicious attack.

Gu Lang was not too worried, because during the challenge, he had set the firewall's defense rules to the highest level, and any suspicious attacks would be rejected. Therefore, when the firewall issued an alarm and wrote this log,

The other party's special data packet has been rejected.

Gu Lang called up the data packet intercepted by the firewall. After opening it, he looked at it carefully and found that the data packet was set up very skillfully. A piece of memory overflow code was cleverly encapsulated into the data packet. If the firewall stored this data

If the package is accepted as a normal service request, then this code will bypass the firewall defense, enter the server, and take the opportunity to cause trouble.

Looking at this encapsulated code, Gu Lang noticed a different signal from it. Some of the experts who had been watching finally couldn't restrain themselves and started to take action.

As if to confirm his thoughts, not long after this encapsulation code was intercepted, the firewall began to issue frequent alarms, and the other party began to make intensive intrusion attempts on the Xuannie firewall. They used the clever encapsulation code just now to use multiple networks.

The protocol tried to access multiple open ports of the server. After all failed, it began to use a special method to scan the server for vulnerabilities and attempted to attack...

Methods like this are emerging in endlessly, so much so that the firewall has been sending alarms. This situation has never happened in the past many days. As a result, the atmosphere in the entire network department has become very tense for a while.

Therefore, Gu Lang has been staying in the network department without leaving. He is always paying attention to the firewall logs and is ready to deal with emergencies at any time.

Fortunately, after this attack lasted for more than an hour, it finally stopped without any danger near midnight, and the firewall alarm no longer sounded continuously.

Seeing this situation, all the employees breathed a sigh of relief. The hour or so just passed was really difficult. It was even more stressful than the large-scale denial of service attack organized by Thunder in the first place, because the denial of service

At most, the attack will make the server unresponsive, but once the previous attack is successful, it will mean that the firewall may be compromised, and the challenge that has lasted for more than ten days will most likely face an ending that none of them are willing to face.

Fortunately, the Xuannie firewall is strong enough and the hacker's attack was unsuccessful.

Gu Lang still stayed in the Network Department and did not leave. At the same time, he felt that things were not that simple. You must know that as a real hacker, in order to invade a server, in addition to having superb technology and a flexible mind, more importantly, he must have

You have enough patience, and the attack just now has only been more than an hour, which is not that long. So, will the other party give up easily? Or is it because after this round of intrusion attempts failed, they started to choose another method?

Sure enough, after he waited for a moment, although the firewall did not send an alarm, he found some abnormalities from the firewall log. When the conventional methods were ineffective, this guy began to study what Gu Lang had done in order to mislead Gu Xiaodong.

That's a trap.

The other party had already entered the trap at this time. He first tried the method originally proposed by skyblue to break through the trap, and then was kicked out by the firewall and his IP address was blocked.

But after about ten minutes, this guy changed a new IP and came in. The reason why Gu Lang was able to determine that the new IP and the previously blocked IP came from the same person was because of this guy.

His technique is very skillful. It is not comparable to those guys who use ready-made tools to enter the trap and then start to run stupidly and then get kicked out. After this guy came in, he seemed very cautious and didn't pay attention.

The so-called target file path specifically used for phishing, but constantly trying other methods for this trap, trying to break through the limitations of the trap. Secondly, this guy's attack is very distinctive and has obvious personal characteristics, such as

The data packet technology that he is best at is something that most people have learned very well, and now, he is once again using that technology to seal some seemingly normal data packets in an attempt to break through the trap.

Gu Lang has been observing this guy, and is very curious about his every move, but he is not too worried, because this guy has not found a way to break through the current trap setting strategy, so after a few more attempts, he will

The firewall deemed it a malicious attack and kicked him out without mercy.

However, this guy seems to be very patient. After being kicked out, he will soon change his IP address to come in, continue to make various attack attempts, and then be kicked out again, come back again, and so on, persevering.

"This guy obviously knew this was a trap and was exploring the trap's setting strategy."

Gu Lang noticed the opponent's purpose after he was kicked out a few times. When he was considering whether he needed to strengthen his trap strategy to make this guy more difficult, he received an unexpected phone call.

"Sister Sa, what can I do for you?" Gu Lang asked unexpectedly.

"We are going to take action soon. If you want to withdraw the trap after twelve o'clock, you can withdraw it." Tang Sa said.

After hanging up the phone, Gu Lang looked at his watch. It was already half past eleven in the evening, and there was still half an hour left. The guy was still trying various strategies in the trap, so he simply ignored it.

If the opponent can find a trap strategy, then break through. Anyway, there is a more powerful defense waiting for this guy behind the trap. When the time comes, let this guy try what it means to be extremely disappointed after ecstasy.

With his mood relaxed, Gu Lang felt a little sleepy, so he found a more comfortable chair in the Lu area and leaned on it to take a nap.

When he opened his eyes again, he was awakened by a piercing siren.

"What's going on?" Gu Lang asked.

"The trap has been breached," one employee replied.
