The countdown to this level is two minutes, the timer has already begun, and the numbers keep decreasing, 119, 118, 117、......

Chen Nan was still expressionless and ordered the dog cub to make a move. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoThis time the puppy still uses the same intrusion method as the first level, but this time it takes advantage of another vulnerability in the other party's TCP/IP protocol to easily deceive the trust of the system and bypass the other party's firewall.

Due to the numerous vulnerabilities in the TCP/IP protocol, the puppy successfully completed the intrusion, and it made two attacks before and after the firewall became an ornament. A true hacker will choose to bypass the firewall and achieve a silent intrusion, rather than piercing the firewall head-on, which is easy to be detected by the other party and thus lose the best opportunity to invade!

"Drop! Congratulations on becoming the 96,304th two-star account! ”

Two-star members are basically half less than one-star members, and since most entry-level hackers choose to break through head-on, it is inevitable to encounter the firewall head-on, which is the most conventional method, but it is also the place where system designers have the most defenses.

If the firewall cannot be pierced within the specified time, the level will be declared a failure. Therefore, most entry-level hackers fail to advance because of the wrong intrusion method! Occasionally, there are successful hackers with large servers in their hands.

In the face of the third level, Chen Nan still let the dog cub shoot, he had clearance experience in his previous life, and he knew the mystery, the first six levels were very simple for him, and he basically didn't need to make a move.

The puppies' skills are all from him, and at this moment, it's like a hanging, all the way through! ……

……

The bulletin board of the forum is broadcast every 10 seconds.

"Congratulations to DK on being promoted to a one-star member! ……”

"Congratulations to DK on being promoted to 2-star membership! ……”

"Congratulations to DK on becoming a 3-star member! ……”

……

This attracted the attention of many hackers who had just entered the stream on the forum, and they left posts to marvel.

"Damn, break through a level in ten seconds, who is so fierce?"

"Dude, I had to go through more than 50 times to pass the first level! …… Kneel and beg for cheats! ”

"Worship the eldest brother upstairs, little brother, I have passed the first level one hundred and six times! ……”

"Visually see that this person has passed six levels at most, and he will not explain!"

“……”

"Congratulations to DK on being promoted to a six-star member! ……”

As this announcement appeared, the font of the forum suddenly turned green.

"Damn, the server is hacked? Asking for an explanation? ”

"Despise the rookie upstairs, this is the forum's way of congratulating DK on his promotion to a six-star membership, and it seems to last for a minute,......"

"The second floor is explaining, is this DK the vest of a certain hacker god? Why is it so short? ”

“……”

Of course, this achievement will not attract the attention of the masters, most of the members who participate in the discussion are members below five stars, but there are a large number of people in this part, so the forum homepage began to swipe the screen wildly! Everyone is also secretly curious about how many levels such a high-profile DK can break through!

Chen Nan didn't know this, and at this moment he chose to continue and enter the seventh level.

From this level, there is an administrator on duty, and the administrator on duty at this moment has already noticed Chen Nan's breakthrough, and has mobilized resources to prepare for defense.

……

At this moment, in a luxurious villa in the far north of Europe, a man sits in a comfortable computer chair with five high-definition monitors in front of him, one of which is showing the Black Abyss Forum. His ID is Hellboy, and it's the name of a movie, Hellboy.

Arrange these two rows of dazzling little stars under this ID, and count them carefully, there are a total of nine of them, which shows that Hellboy is actually a nine-star member!

Hellboy is the server guard today, his real name is Anderson, and he belongs to a Norse aristocratic family. Dressed in comfortable pajamas and a cigar between his fingers, he was staring intently at the home screen, his piercing gaze sweeping over the other four screens.

"You must teach this kid a lesson, it's so arrogant!" There were words in his mouth.

Today he decided to teach this arrogant DK a lesson, he wanted this guy who didn't know what a real hacker was. So this time he was extremely serious, which he had never done before.

That is, the forum has a rule, and this level is not allowed to counterattack, otherwise he will definitely blow up the IP of this DK.

……

When you reach the seventh level, you will encounter a hacker master, it will be an offensive and defensive battle, Chen Nan didn't use the dog cub this time, he has to take action personally, after all, the dog cub is just pseudo-intelligence, and he can't compete with the other party!

The time limit for this level is 10 minutes, and when you tap the keyboard with both hands, a piece of code is quickly formed, and this time Chen Nan wrote a Trojan horse program with only one function - to query the IP addresses of other data streams.

He used a scanning tool to scan the front, and soon encountered a powerful data stream, at this time, Chen Nan couldn't fight head-on, the other party's server was a supercomputer, and if he fought hard, he would be turned into slag in seconds!

Stop scanning, and at the same time he added a shell to the Trojan and hid it in his data stream, and when he touched the other party, the Trojan was activated instantly, and the other party's proxy IP address was transmitted back.

Chen Nan knew that this was just the other party's broiler proxy IP address, but it was enough.

His hand speed increased again, and a disguise program was soon born, pretending to be the IP address of the other party's proxy to try to connect to the server. Due to the trust relationship between the host, the connection was successful without accident, and at this time, it can be said that Chen Nan is like the server administrator Hellboy, although the management authority is very small, but he can also mobilize a small amount of computing resources.

Chen Nan began to look for the management authority of the simulation server, and finally found the other party's ID at the bottom of the management group - Hellboy, but he did not have the right to change the permission at this time, of course, he only needed to leave a mark under this management group, and the system judged that the level was successful!

In fact, he didn't do it for the next step, what he needed was to make a splash, not just to move up the membership level.

At the critical moment, he exploited a vulnerability that has not yet been discovered, easily obtained core administrative privileges, and then kicked out all members of the administrative privilege group, leaving only his ID.

He did the perfect invasion!

"Di, congratulations on becoming the 5337th Seven Star Member!"

At the same time, in distant northern Europe, the four screens in front of Hellboy suddenly dimmed, leaving only the most marginal screen, which was showing the front page of the forum.

Hellboy was at a loss, he didn't even know what was going on before he was kicked out of the server. The dignified nine-star members were killed in seconds like this, which was unimaginable before!
