Personal information of about 20 million people, which amounts to two fifth of the entire South Korean population, has been compromised in the country's worst identity theft. Customers of the affected three major credit card firms gasped at the sheer extensiveness of the breach; it is not just the user's real name, home/work address, cellphone/home/work phone number, social security number, but in many cases, even user's credit limit, credit history, credit card expiration date, and credit records have been stolen. Korean online venues flooded with angry users’ comments and one net user even set up a fake website entitled ‘Trade My Info; the No. 1 Online Personal Info Trading Venue’ [ko]. Its intro sarcastically proclaims that instead of letting the identity thief sell your personal info, users should rather trade their info by themselves and make a a modicum of money out of it. Most of the site's links lead to related news articles on the breach. An extensive post on Korean reactions to the country's worst ID breach will soon be posted on Global Voices.
