Hackers targeted by North Korea go down all the northern sites with an angry retaliation

─ North Korean overseas sites are temporarily out of access.A year ago, if I correct the original, I shouldn't be angry, the north was igniting a hacker

Various North Korean websites have become unable to access one after another for the past month......

North Korea's public websites have been discovered one after another for the past month.Despite the suspicion of an intelligence activity by a foreign government, it was found that the reality was an angry hacker.The US WIRED magazine reported in interviews with the hacker himself.● Exactly “artificial snow” festival!North Korea, which was captured by "satellite photos" around the Beijing Olympics, operates dozens of websites overseas.The Kim Jong Un administration's official website, related sites for propaganda purposes, and reservation sites for state -owned airlines and Koryo Airlines.However, from mid -January, these sites began to be interrupted intermittently.On January 26, peak, access to all sites in North Korea from overseas was lost.British security researcher Genaid Ali, who monitor the communication situation, describes the "mysterious large -scale attack on the Internet in North Korea."Other Internet -based services, including emails, have stopped, and Ali says that it was a "de facto suspension of the Internet that affects the country."The cause is a cyber attack by someone.One or more major routers, which judge access to North Korea from overseas, have been able to handle requests because they have been attacked.The attacker was only one hacker burned by anger.■ Hacker North Korea, targeted by North Korea, has fired missiles one after another in January.From the timing, the company was initially suspected of organized intelligence by foreign governments.However, behind a series of attacks was the only hacker called P4X.WIRED magazine reveals the story."In fact, it was an American man, a T -shirt, pajamas, and slippers. I enjoyed an alien movie in the living room in one hand with a spicy conak in one hand.In order to confuse the whole country's Internet, he was checking the running program. "P4X is anonymous on security, but as a proof that he is an attacker.The screen capture of the attack was presented to the magazine.It was my grudge that I was using it by North Korea who drove him into action.In January last year, he received a software from another hacker with no acquaintance.However, soon after that, information that should be anxious will come in.North Korea is targeting Western security researchers and distributing suspicious tools to set up a backdoor.The backdoor is the back door for sneaking into a PC.If it is set up, there is a danger that a PC will be hijacked by remote control from the outside through the omission.When P4X confirmed the software in question, it turned out that this backdoor was just prepared.Fortunately, he executed the main damage because he was running tools in a form isolated from the main environment.However, he realized that North Korea was aiming for himself, and he said, "I was shocked and struggled."It was reported to the FBI, but there is no sign of any effective measures because the subject was not a government or organization but a personal security researcher.One year later, in January this year, he moved to direct retaliation to North Korea.It was said that the actual attack was easier to return if he decided to retaliate once in the guideline of a vulnerable test.P4X usually works as a security researcher.He is familiar with vulnerability and attack methods, and provides know -how to prevent attacks using them, contributing to self -defense of companies and organizations.As part of that, he was good at the penetration test.The test is intentionally attacked based on requests from companies and other companies to test the robustness of the system.The basis is to combine the known vulnerable to hit weaknesses.North Korea, on the other hand, has been using old versions that have already known a large number of vulnerability.P4X has been able to apply it to North Korea, and has completed a relatively small penetration test, completing an automatic attack tool for North Korea.When he did it, he said, "The more interesting it was, the easier it was."P4X has not disclosed the details of the attack to make the North Korean side difficult.However, it explains that it is a type of "service refusal (DOS attack)" that down the server by sending large or illegal data.The North Korean side has recovered the server several times, but it seems that the fundamental response has not been taken.If P4X runs your own program, you can down the site as many times as you want.■ The deterrent to the north claims that the attack on North Korea may be legally a problem, and that there is nothing ethically wrong.There are few general citizens in the country who can use the Internet, and communication that browsing overseas sites from North Korea has not been affected, so there is almost no impact on citizens.Only the government that operates propaganda sites is affected.In addition, he hopes that a series of attacks will be a deterrent to North Korea, which aims for European and American security researchers."If we don't realize that we have fangs, (attacks) will last forever," he told WIRED.On January 31, he launched a project called "FUNK" on the Dark Web.In the future, we intend to gather other cyber activists who are aspiring and challenge North Korea with the power of the group.
