On February 18th, a file titled ‘All 2nd year individual transcripts’ was uploaded to a Telegram entrance exam data sharing chat room with 18,000 participants.
The grades data containing the names, schools, and ranks of 270,000 high school sophomores across the country who took the national joint academic evaluation last November were leaked from the computer network of the Gyeonggi Provincial Office of Education.
On the 26th of last month, the police, who conducted an investigation for three months, caught the hacker who stole the data.
The main culprit, the teenage hacker, was a college student who entered a computer-related department this year.
From October of last year, when he was a senior in high school, to February of this year, just before entering college, he accessed the computer network of the Gyeonggi Provincial Office of Education more than 200 times and illegally downloaded more than 100 data.
And in February of this year, I handed over the grades to the operator of a Telegram chat room that shares information about the entrance exam.
The two were not even close to each other.
The purpose was to show off hacking skills.
The chat room operator, who was a re-study at the time, uploaded the handed over data to the Telegram room for display.
Eventually, the two were arrested.
A total of nine people were handed over to the prosecution on charges of illegally accessing the education office’s computer network or distributing data.
The school district site that was targeted was too lax.
It has been confirmed that the arrested teenage hacker also taught the method to other teenagers he knew.

″It was a relatively easy method that even high school students could download if they knew the illegal download path.″
As a result of an investigation by the Ministry of Education separately from this investigation, it was additionally confirmed that the data of 2.96 million applicants for the academic evaluation conducted in 2019, 21, and 22 were also leaked from the computer network of the Gyeonggi Office of Education.
The Gyeonggi Office of Education said, “Instead of using its own computer network, it entrusted the management of grade data to the Korea Institute of Curriculum and Evaluation like other offices of education in Seoul, Incheon, and Busan.”
