On one of the screens, Jonathan's own vulnerability scanning software was also hung. Pen "Fun" Pavilion www.biquge.info

In fact, most powerful hackers are accustomed to using tools written by themselves, because everyone has different characteristics, and only they know best what features they need.

The same unique software, the ability to analyze vulnerabilities and the speed of computing are far beyond Zheng Guangyu.

And the firewall that was decent for Zheng Guangyu was simply useless in the eyes of Zhang Yang at this moment.

……

Zheng Guangyu's first thought was that Lin Yujia directly left the back door for the other party, but out of affirmation of Lin Yujia's character, he immediately ruled out this idea.

Immediately afterward, he immediately suspected that the other party had hacked into Jiang Da's server before, and contacted Lin Yujia's acquaintance with him, and he confirmed this idea almost immediately.

Although he was a little angry, the content of the competition was originally specified by himself, so naturally he couldn't blame others. However, it was just an inconsequential competition, but it rarely aroused his competitive spirit, even if the opponent was one step ahead, but there was still a chance to teach the other party a lesson in the subsequent server attack and defense.

He straightened his back, and his nonchalant fingers quickened......

……

After Zhang Yang broke into the core, while beginning to quickly elevate his authority, he cautiously probed the existence of the other party, because he had delayed a lot of time to disguise himself before, he was afraid of being thrown away by the other party, and he almost broke through the perimeter protection as quickly as possible, so that he didn't notice Zheng Guangyu who was in the periphery at that time.

Zhang Yang frowned, he had already obtained the superuser permission, but he still did not find any trace of the other party. Just as he was in doubt, a strange movement from the periphery instantly alarmed him, who was now the controller of the server.

"No......" he thought, seeing that the disguised data stream was preparing to invade the kernel with a weak password, he gave a command to block the route.

……

In front of the computer, the corners of Zheng Guangyu's mouth twitched, and his fingertips accelerated again.

SQL injection vulnerability, ASP upload vulnerability, SA injection point exploit...... In addition to DDoS attacks. One method after another is used, but it is discovered by the other party again and again, and then cracked.

He was so engrossed that he didn't notice it at all, and his expression was getting more and more solemn......

He was like a great enemy.

……

And early in the morning into the server. Lin Yujia, who was in the third-party viewing position, opened his mouth wider and wider.

If she hadn't identified herself in time just now, I'm afraid she would have been kicked out by Zhang Yang a long time ago......

……

Zhang Yang methodically defused the other party's invasion, but his brows gradually furrowed.

The vast majority of hackers don't like to defend, let alone Jonathan, who is known for his invasions. Coupled with the fact that most of the simulation time had passed, and the other party's invasion was still endless, Zhang Yang finally decided to take the initiative.

On the mechanical keyboard, the fingertips suddenly fly.

The windows are constantly flashing, and the instructions one by one are like swiping the screen.

On the one hand, Zhang Yang filled in the loopholes and dealt with the other party, but on the other hand, he was like a night owl hidden in the quiet night, quickly and covertly tracking the other party's address.

The other party is obviously a little sophisticated, and he used a proxy at the beginning, but his flamboyant expression did not fluctuate at all.

The eyes kept scanning back and forth between the two screens, tracking. Cracking, Calculating, Analyzing......

Then confirm.

When Zheng Guangyu, who was attacking frantically, realized that he had been invaded, it was completely too late.

Forty-three seconds, his computer was completely controlled by Zhang Yang.

……

All the data flow is frozen in an instant.

Lin Yujia was stunned, she never imagined that the person who would lose in the end would be her teacher, and it was like this...... There is no way to fight back.

Zhang Yang was stunned. After asking Xiao Zhu to stop the simulation, he suddenly remembered that the person opposite was Lin Yujia's teacher, and he was in high spirits...... Paralyzed his computer.

Zheng Guangyu was stunned...... Well, he didn't stay...... It's just that the computer doesn't react at all. It doesn't make a difference whether you're stuck or not.

With a wry smile, his old face turned slightly red.

Where is this a powerful hacker in Lin Yujia's mouth, this is a top hacker at all......

How could such a hacker not know about Polar Night, and how could he take care of Lin Yujia, a little rookie......

He really couldn't figure it out.

……

Zhang Yang is so embarrassed, according to his previous style. At this time, he should lightly type the three big words "You lost" on the other party's computer, but thinking about the consequence, it may be that Lin Yujia is looking for himself to work hard, so he shook his head and forgot it.

Or say "hello"? Or "you're strong"? Zhang Yang thought about it and felt that it was very bad to say anything at this time, so he silently released control of his computer, and then went offline and left......

The kaleidoscope went offline, Zheng Guangyu's computer resumed control, and Lin Yujia finally came back to his senses.

"Uh, teacher, look at him...... Okay......"

Zheng Guangyu shook his left hand, which was so sore that he almost cramped, and smiled bitterly and typed with one hand: "You say it's okay." ”

"Uh...... Hehe...... Hehe......"

Lin Yujia covered his face, and he really couldn't think of what to say.

Publicity...... You asshole...... You can't save face for my teacher......

Zheng Guangyu drank the cold strong tea on the table in one gulp, and asked seriously: "Yujia, you tell the truth, how did you know this person?" ”

Lin Yujia's face froze, and he almost didn't think about it, so he said according to the statement agreed with Zhang Yang before: "He invaded our Jiangda server that day, and it happened that I was maintaining it remotely, but it was still occupied by him, so I met ...... like this."

"Huh......" Zheng Guangyu exhaled deeply and nodded, he really couldn't think of any other motives the other party. If other organizations send people to spy on them, it is absolutely impossible to find such a top hacker. And the polar night is just a forum for mutual communication, although the member review is a little stricter, but it is not difficult to enter.

After figuring this out, although I was still a little depressed, I was also happy to have found such a powerful hacker: "I sent you the invitation code, if you meet him, forward it to him." This time...... You've really dug up a great god......"

The two chatted a few more words, and the apologetic Lin Yujia hurriedly went offline, grabbed his mobile phone and was about to call Zhang Yang, but what rang was a prompt sound that the phone had been turned off.

"Bastard ......"

……

Zhang Yang threw the turned off mobile phone to the bedside, and thought of Lin Yujia's embarrassing scene after he left, he laughed wickedly.

Lin Yujia's teacher is indeed worthy of what she calls a "master", even if his energy and hand speed have declined because of his age, he can barely hang at the end of the first-class.

It's a pity that between the first-class and the top, there may be a gap that countless people can't cross in a lifetime.

Of course, it's not that her teacher is not good, it's just that his field is not a hacker, but an orthodox academic computer expert, and he can definitely be called a master in advanced computer theory. At the level of hackers, there is naturally no need to be demanding.

Stretching in satisfaction, he asked Xiao Zhu about helping Su Yiqing prepare the tutorial, Zhang Yang climbed into bed and began today's training. (To be continued.) )
