Personal computers (PC) were attacked by '3·3 DDoS'. This attack followed a '7·7 DDoS' attack which appeared on 2009. The attack targeted the destruction of major government computers, bank facilities, and various portal sites synchronistically. '3·3 DDoS' is very similar to '7·7 DDoS' in that they both launch at preset time.
DDoS stands for ‘Distribute Denial of Service attack’ and is one way computers can be hacked. Once a computer is hacked, the PC is transformed into a ‘zombie PC’. Normally the virus can enter a PC through many routes. For example, through Active X installed on some web sites and through downloading programs. Also viruses can be delivered in e-mails, hyperlinks and attached files. University students usually get internet material like dramas, information and software which makes these PCs more likely to be attacked public computers because they do not usually have adequate vaccine programs.
The virus penetrates the PC and conceals itself. It is very difficult to tell if a computer has been affected. Hackers create minimum changes to hide themselves. For this reason people normally do not know whether their PC is a 'zombie PC' until it is too late.
When activated, the malignant codes enter appointed sites by the attacker's orders and paralyzes them. According to the Korea Communications Commission, there are 77,207 'zombie PCs' mobilized for DDoS aggression. Kim Mi-young said "All of a sudden my computer didn’t work. I was worrying about my computer's speed which had slowed down but I couldn't imagine that my computer had been infected by virus. Normally I didn’t care about viruses. They were someone else’s concern until it actually happened to me." The Korea Communications Commission(KCC) announced that some 400 PCs were broken after the attack and the time took from 4 to 7 days for the destruction. Hwang Cheol-jeung, director of KCC network policy, said "We know that other infected PCs are still out there” and he recommends checking your computer with a virus checker consistently.
Dongguk University Information service center also advises ways to defend against viruses to students who work a lot on computers. Above all the things, students should abstain from P2P(peer-to-peer) site use and must not download illegal recordings. When checking emails, they should also be sure they know the sender. If the sender is uncertain, never open the e-mail. Also be cautious when installing ActiveX or when visiting web blogs.
Many experts suggest installing free-vaccine programs like V3, Naver vaccine and ALYac. These programs always keep checking for new vaccines through automatic updates. Prior to this, however, users make sure they have not already been infected. For this, there is a service offered by The Korea Information Security Agency called Bohonara’s free service in which the results of infection will be immediate.
While The Korea Communications Commission announced that new attacks may occur they also warned of many cases of fraud. Some of the most common are fake sites similar to free-vaccine sites in which swindlers will try to encourage you to pay for their services. These sites often have imitation sponsor links for other famous sites. Police urge for all to be careful.
Another damage is EBS was harmed by 'DDoS'. EBS is one of the biggest public education sites in country. This attack was a deed of a student who got angry because of teacher's scolding.
In opposition to rebuke, he destroyed his own school's homepage. Once he had achieved this, wondering whether it is possible to do the same to EBS site. So he did. As a result of this action, EBS was paralyzed about a day and fifty thousand students couldn't take lectures. He is examined by the prosecution but the prosecution indicts without physical detention because of attacker's position, student.
The prosecution said, "For a while, harm will hold out. Because transformed virus appears persistently. So like KISA said, to examine closely is essential."
Government declares to make security program. Government said, "Through this circumstance, we experience an emergency of PC's security. And we feel a sense of responsibility for constructing of PC security. We will enter into partnership with AnLap security business. Maybe the newest vaccine program will supply for free soon." And they emphasize to prevent the third DDoS by so doing.
