Authorities from the Asian country of South Korea revealed on Thursday that computers which were tagged with internet protocol (IP) addresses from China may have accessed data from accounts of 25 million South Koreans.
According to the Korea Communications Commission, these computers with Chinese IP addresses may have gained access and stolen private data of the 35 million South Korean accounts after they breached nate.com and cyworld.com.
IP addresses are similar to telephone numbers and give the country where the internet connection was established.
Nate and Cyworld are both run by SK Telecom, the country’s current biggest mobile telecommunications company. Nate is a web portal which offers a portfolio of web services including search and instant messaging while Cyworld is a blogging service and social networking site.
According to reports, the hacking of possibly 35 million South Korean is currently the biggest cyber attack the country has experienced yet.
South Korea says that information which may have been stolen in the cyber attack include names, phone numbers, email addresses and resident registration numbers.
