An incident in which sophomores in high school stole test questions from hacking has occurred and is shocking.



It turns out that the school's security has been breached in vain for high school students who do everything they can to get into the university they want.



The Gwangju West Police Station, which accelerated the investigation after the media reported on the Gwangju Daedong High School test question leak, released some of the progress of the investigation today (27th).



It was last January that second-year classmates A and B had the idea of ​​extracting test questions and answers from the teacher's laptop.



The people who talked about the existence of malicious code that can steal internal information if planted in a laptop secretly decided to extract the test questions and answers and made a detailed plan.



Group A, who is good at programming, edited the malicious code using the coding learned in school or the hacking method learned on the Internet.



Groups A and B, who succeeded in creating a program that periodically captures (captures) and saves the screen when installed on a laptop secretly, decided to install this malicious code on the laptops of teachers who take exams in advance.



There were still many obstacles to trying to commit the crime.



First of all, I had to sneak into the school office where the teachers' laptops were located to escape the school's security facilities.



However, the school's security facilities were weaker than expected.



The CCTV installed in the school did not illuminate the school office, and there was no alarm system installed by a private security company, or it did not work even if children sneak in.



The windows of the classroom were not locked properly, so students could easily enter the classrooms located on the 4th and 2nd floors, respectively, by climbing the railing on the 4th floor or holding the drain pipe from the ground.



There were guards at night on campus, but we could not find any students who sneaked into the school at night several times before the midterm and final exams.

Computational security was also easily penetrated by the hacking skills of high school students.



Each teacher's laptop had a password, but group A simply cracked the laptop password using a method that he found through an internet search.



Teachers did not notice the fact that a malicious code was planted that continuously captures and stores the laptop screen during the exam period.



After the exam was finished, the students broke into the office again, took out the screen capture file of the exam question stored deep in the USB on the laptop, and deleted the malicious file without a trace.



It was revealed that the academic calendar was also exposed to the students.



In groups A and B, teachers knew exactly the deadline for submitting exam questions in advance, planted malicious code before the deadline, and collected files after the exam was completed.



However, in the end, the meticulous crimes of groups A and B were caught while taking the test poorly.



Group B, who could not memorize all the answers to the test questions to be leaked, secretly wrote the correct answer on a note, took the test, and tore the note with the answer in the trash can, but was suspected by a classmate who saw it, and the whole story was finally revealed.



Even during the test, there was no test supervisor who discovered the misconduct of Group B, who secretly wrote down the answers on the note.



It is said that the students who committed the crime together revealed the motive for the crime, saying, "I committed the crime to improve my grades because there was a specific university and department I wanted to go to."
