After Qu Sen learned a few things, he was eager to try his hand at it. After receiving the two softwares that Sun Limei gave him, he opened them to look for loopholes in them.
However, the problem was that until now, other than familiarizing himself with the operating principles of the two software components, he had not made any progress in finding vulnerabilities.
Therefore, the situation was a bit awkward.
The opportunity was already given. Whether or not Qu Sen could seize it depended on his ability. However, the reality was that Qu Sen's operating rights were deleted by Lady Zhou in the two software. There was no way to break it from the outside.
Originally, Qu Sen wanted to use the method he used to crack the command system of the armored forces and directly start from the database. However, one of the two software was independently developed on the basis of the Linux system. The other software ran on the Linux platform. The database files were also encrypted.
His knowledge on the Windows platform was basically useless.
Qu Sen, on the other hand, could slowly test out the type of data packet and then use the stupid method of brute force to crack the encryption format.
The problem was that with the computing power of the IBM computer in his hands, by the time he was done, the summer vacation would be over.
The final exams were approaching day by day. However, Qu Sen spent all day looking at his IBM computer. He searched for relevant information on the military network while scratching his head. His days were very painful.
As the public subject exams began, Qu Sen realized that he could not let himself go. He could not just focus on the computer. If he messed up the exam again, he would be done for. Therefore, he temporarily put down the computer and focused on revising and reinforcing the knowledge points of the six professional courses.
At the same time as the public exam ended, the professional exam began. As expected, Qu Sen easily completed all the papers for each exam. After each exam, he estimated his score. If he did not make any mistakes, he should be able to score more than 65 points in all six subjects.
After removing the pressure of the exam, Qu Sen turned on the computer again. He added a bunch of self-made software to monitor the backend, memory, and various ports. He was struggling to find a way to hack into the computer.
The school had a tradition. After every final exam, the students did not need to wait for the results to come out. They would check the results on the phone when they went home. This year, they could check the results online. Therefore, after the exam, the students who did not have anything else to do could go home.
Lady Zhou gave Qu Sen an ultimatum during dinner. She and Li Ying would wait for three days. If Qu Sen did not come back in three days, the two of them would buy tickets and leave.
This was not the end. After they left the cafeteria, Qu Sen's mother called again. She wanted to say, "Son, did you finish the exam? Is the ticket? If not, I'll send you the ticket. "
Qu Sen knew that it did not matter how he went home, what was important was the speed of his return home. His mother just wanted him to hurry back and meet with "170" as soon as possible. She wanted to take advantage of the summer vacation to build a good relationship foundation. This was to prevent the girl from falling in love with someone else when he went back to school first.
When Qu Sen heard his mother's "ill-intentioned" question, he decided that he could not continue like this. Otherwise, if he brought Zhou Li back, his mother would not be prepared at all. When he and Zhou Li entered the house and found "170" sitting in the living room, the scene would be extremely awkward.
After he made up his mind, he organized the medical language in his mind. He quietly cleared his throat and stabilized his voice, "Mom … Um, I have something to tell you."
"What is it?" Qu Sen's mother subconsciously thought that her son had something to do during the summer vacation and could not come home. Her voice instantly became alert.
"Um … I have a good friend in school. Her family is inland, so I want to take her back to our house to see the sea during the summer vacation. "
"Hey, then come back together. We're both classmates …" Qu Sen's mother's attention was all on whether her son would come home during the summer vacation. When she heard that Qu Sen wanted to bring a classmate home, she did not think much of it.
But halfway through her sentence, she suddenly realized a very important problem. Her tone changed, "Son! Is it a boy or a girl? "
"Cough ~, um, a girl!" Qu Sen gave a very definite answer. At the same time, his voice was slightly shy.
"A girl ~!" His mother's voice was full of surprise and joy. After digesting the latest information, she immediately asked, "How old is she? What is her major? Where is she from? What does she look like? "
"…" Qu Sen was speechless, but he had to answer. He could only reply one by one, "She's one year older than me. She's a master's student in our school. Didn't I tell you? She's inland. As for what she looks like … You'll know when you meet her."
"Master's student!" Other than the few words about education, his mother completely ignored the rest of the information. After pondering over it for a while in surprise, she added, "How old are you?"
"One year older than me ~"
"Oh, one year older is good, one year older is good!" Qu Sen's mother was very happy. After giving Qu Sen's father an excited look, she quickly said to the phone, "Son, quickly tell me your bank account number. I'll transfer the money to you tomorrow morning. Don't take the bumpy train ride. Take a plane back! "
Seeing that his mother was much more excited than he had expected, Qu Sen began to feel uncertain. He quickly added, "Mom ~ Mom, don't get too excited. It's just a thought. I'm not sure if she'll go back with me!"
"Go back! Why won't she? She's shy. Give her the phone. I'll talk to her. "Qu Sen's mother was completely unreasonable.
After hanging up the phone, Qu Sen didn't want to waste another second. He ran all the way back to the dormitory. He prepared for the next three days. Even if he didn't sleep or rest, he was going to hack the two damn systems in the computer.
Qu Sen was constantly testing the laptop, trying to find loopholes. The atmosphere in the class was very lively. The exam was over. Everyone's efforts this year were not in vain. The estimated score was very optimistic. Those who had already booked tickets were packing up, and those who hadn't booked tickets were letting the sheep loose.
Ke Lan was anxious to go home. She had booked the ticket a few days in advance. In order to rush for time, the last exam in the afternoon was handed in fifteen minutes early. When Qu Sen left the exam room, he was already on his way to the train station.
Gao Bo, who lived in the local area, had learned his lesson from the first half of the semester. He worked very hard this semester, and his estimated score was also very good. Therefore, he wasn't in a hurry to go home. Instead, he wandered around the few dormitories he was familiar with.
He was showing off until ten o 'clock. Gao Bo came back from the class next door. When he saw Qu Sen was still messing around with the computer, he went over and put his arm around Qu Sen's shoulder to watch the show.
After watching for a while, he more or less understood what Qu Sen was doing. He said, "You're too low. Nowadays, hackers attack through the internet. Unlike you, you're still working hard on the keyboard."
"Nonsense, it's an internet attack! It's easy for you to say. Can you find me another computer? "Qu Sen said unhappily.
"Hey, don't you watch movies? In Mission Impossible and James Bond, phones are used. What's the use of a computer? Isn't your phone smart? Can you play games? "Gao Bo disdainfully retorted.
"F * ck …" Qu Sen instantly stopped what he was doing. His two eyes turned to Gao Bo as he tightly grabbed his hand and said affectionately, "Comrade Little Gao Bo, you're my brother!"
"Shoo shoo shoo. What's the point of all that nonsense? Why don't we do something more practical?" Gao Bo muttered.
"From next semester onwards, my cigarettes will be your cigarettes, my bed will be your bed, and my notes will be your notes." In order to express his gratitude, Qu Sen basically had no bottom line.
"Forget it. Those were mine in the first place. Why don't you say that your subsidy is my subsidy?" Gao Bo's words were very self-righteous.
"I'm under a financial blockade. It's not like you don't know that." Qu Sen's face instantly turned bitter.
Although the other students had been fooled by rumors about his relationship with Zhou Li, it couldn't be hidden from the 510 students, let alone his best friend Gao Bo. He was well aware of Qu Sen's financial blockade.
When he saw Qu Sen's pitiful appearance, Gao Bo responded with severe disdain and sympathy.
"Sigh ~ Okay, okay. You play by yourself. I'm going out for a smoke."
