Korean businesses, financial institutions and government agencies have been frequently targets of hacking in the past. It is like an epidemic. The latest case involves SK Communications, which runs the Cyworld social networking website and the Nate online portal.
The hackers, whose attacks reportedly originated in China, stole personal information of 35 million clients of Cyworld and Nate last week. The victims are now exposed to the risk of online scams and voice phishing.
SK Communications claims the hackers cannot easily use much of the personal information they have obtained because the passwords and resident registration numbers of the clients encrypted. But if the culprits are capable of hacking such a security-minded Internet portal as Nate, they may easily decode the encrypted information.
Moreover, it is commonly accepted that there is no foolproof method to permanently deny a determined, competent hacker access to computer networks. He will eventually find a way to crack the software defense to get access to the targeted information no matter how technologically sophisticated it may be.
Of course, this is not to say that nothing can be done as a precaution against hacking. Damage can be controlled though it may not be prevented, as evidenced by what SK Communications is planning to do as a remedial measure.
