Wang Jialing didn't know that the change in wind direction had actually been brewing since ten o'clock in the evening, and what he saw was just the result of an outbreak after a long time of brewing.

On the evening of the 11th of January, Gu Wolf finished his day's work and stayed in the network department as always, paying attention to the operation of the Xuanne Firewall.

At ten o'clock in the evening, the firewall suddenly issued a burst of alarms, which attracted everyone's attention.

"Network traffic has been at a low level, and it is clear 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 Wolf opened the firewall log, but found that someone was scanning the open port of the server and trying to access an open port of the server, and the reason why the firewall gave an alarm was because the method used by the person who tried to attack was a little different, and the packets requesting the service were different, so that it was difficult for the firewall to judge whether the request was a normal request or a malicious attack.

Gu Wolf didn't worry too much, because during the challenge, the defense rules of the firewall were set by him to the highest level, and any suspicious attacks would be rejected, so when the firewall issued an alarm and wrote this log, the other party's special data packets had already been rejected.

Gu Wolf called up the data packet intercepted by the firewall, opened it, looked at it carefully, but found that this packet was set up very skillfully, a memory overflow code was very cleverly encapsulated into the packet, if the firewall accepted this packet as a normal service request, then this code will bypass the defense of the firewall, enter the server, and take the opportunity to make trouble.

Looking at this encapsulated code, Gu Wolf sensed a different signal from it, and the masters who had been watching finally couldn't hold it back and started to do it.

As if to confirm his thoughts, soon after this piece of encapsulation code was intercepted, the firewall began to give frequent alarms, and the other party began to make intensive intrusion attempts on the Xuanne Firewall, using the clever encapsulation code just now, using multiple network protocols to access multiple open ports of the server, and finally after all failed, he began to use a special means to scan the vulnerabilities of the server and try to attack......

Such means are endless, so that the firewall has been giving alarms, which has never happened in so many days before, and as a result, the atmosphere of the entire network department has become very tense for a while.

Because of this, Gu Wolf has been staying in the network department, not leaving, and always paying attention to the logs of the firewall, ready to deal with emergencies at any time.

Fortunately, after more than an hour of attack, it finally stopped near midnight, and the alarm of the firewall stopped ringing.

Seeing this situation, all the employees breathed a sigh of relief, the more than an hour just now was really a little difficult, and even more nervous than the large-scale denial-of-service attack of the original thunder organization, because the denial-of-service attack made the server unresponsive at most, but once the previous attack was successful, it would mean that the firewall might be compromised, and the challenge that lasted for more than ten days was likely to face an outcome that they were not willing to face.

Fortunately, the Xuanne Firewall was strong enough, and the hacker's ** blow was unsuccessful.

Gu Wolf still stayed in the network department and did not leave, and at the same time felt that things were not so simple, you must know that as a real hacker, to invade a server, in addition to having superb technology and flexible mind, more importantly, you must have enough patience, and the attack just now has only passed more than an hour, and the time is not very long, so, will the other party give up easily? Or is it because this round of invasion attempts failed, and they began to choose another method?

Sure enough, after he waited for a while, although the firewall did not send an alarm, but from the firewall logs, he found some abnormalities, this guy began to study the trap that Gu Wolf had used to mislead Gu Xiaodong before, when the conventional methods were ineffective.

The other party has entered the trap at this time, first using the method proposed by Skyblue to break through the trap to try, and then was kicked out by the firewall and his IP address was blocked.

But after about ten minutes, this guy changed to a new IP and killed it, the reason why Gu Wolf was able to determine that the new IP and the previously blocked IP came from the same person, first, because this guy's methods are very skillful, and it is not at all comparable to those guys who use ready-made tools to enter the trap and start to go on a stupid rampage, and then be kicked out, after this guy came in, he was very cautious, and did not pay attention to the so-called target file path that is specifically used for fishing, Instead, he kept trying some other methods for this trap, trying to break through the trap's limitations, and secondly, this guy's attack is very distinctive, and has obvious personal characteristics, such as the data envelope technology he is best at, which is very learned by ordinary people, and now, he is once again using that technology to seal some seemingly normal data packets, trying to break through the trap.

Gu Wolf has been observing this guy and is very curious about this guy's every move, but he is not too worried, because this guy has not yet found a way to break through the current trap setting strategy, then, after a few more attempts, he will be identified as a malicious attack by the firewall and kicked him out unceremoniously.

However, this guy seems to be very patient, and after being kicked out, he will soon come in with another IP, continue to make various attack attempts, and then be kicked out and come in again, and so on, perseverance.

"This guy obviously knew it was a trap, and this was a strategy to detect the trap."

Gu Wolf realized his purpose after the other party was kicked out a few times, and was thinking about whether he needed to continue to strengthen the trap strategy to make this guy a little more difficult, but he received an unexpected phone call.

"Sister Sa, what's the matter with you?" Gu Wolf asked unexpectedly.

"We're going to do it soon, and you can withdraw the trap after twelve o'clock." Tang Sa said.

After hanging up the phone, Gu Wolf looked at his watch, it was already half past eleven in the evening, and there was still half an hour, and that guy was still trying various strategies in the trap, so he simply ignored it, if the other party could find a trap strategy, break through, anyway, there is a more powerful defense waiting for this guy behind the trap, and then let this guy try what is called extreme loss after ecstasy.

In a relaxed mood, Gu Wolf felt that he was a little sleepy, so he found a comfortable chair in the network department and leaned on it to take a nap.

When I opened my eyes again, I was woken up by a shrill siren.

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

"The trap has been breached." An employee replied.
