SEOUL, March 2 (Reuters) - A cyber attack from China has
crashed the website of Lotte Duty Free, a company official said
on Thursday, at a time when South Korean firms are reporting
difficulties in China following the deployment of a U.S. missile
defence system on their home soil.
Distributed denial-of-service (DDoS) attacks - when servers
are bombarded with requests - crashed the website around 12:00
p.m. (0300 GMT), the official with direct knowledge of the
matter told Reuters, requesting anonymity as the matter was
sensitive.
"The website is down due to DDoS attacks from China," the
official said.
The Chinese website for the entire Lotte Group,
www.lotte.cn, is also down. It has been offline since Wednesday
due to a virus, spokesman Kim Min-suk told Reuters on Thursday.
"The (two) websites have been down and we are working to get
them back online," Kim said, declining to comment on the nature
or origin of the virus or the origin of the DDoS.
The crashes comes after affiliate Lotte International Co Ltd
on Monday approved a land swap to allow the U.S. Terminal High
Altitude Area Defence (THAAD) system on what was once its
property in response to the North Korean missile threat.

Neighbouring China objected to the deployment of the system,
which has a radar capable of penetrating Chinese territory,
saying it will destabilise regional security while doing little
to contain heightened security risk on the Korean peninsula.
Russia also opposed the deployment, scheduled for completion
this year.
South Korean companies have reported increasing difficulties
in China since deployment was confirmed in November, with
Chinese state media calling for a boycott of South Korean goods.
South Korean artists have also said performances had been
cancelled without clear explanation. urn:newsml:reuters.com:*:nL3N1GD37F
A spokesman at Lotte Mart told Reuters that the retailer's
website was accessible on e-commerce platform JD.com (http://lottemart.jd.com),
but that the site did not appear in search results. Lotte Mart
has asked JD.com to address the issue, the spokesman said.
Also this month, Lotte Group said Chinese authorities halted
construction at a multi-billion dollar real estate project after
a fire inspection. urn:newsml:reuters.com:*:nL4N1FT2P4
Shares in Lotte Group's flagship retailer, Lotte Shopping Co
Ltd 023530.KS , which has about 120 stores in China, fell as
much as 7.8 percent on Thursday. Lotte Confectionery Co Ltd
004990.KS shares fell 2.8 percent, while the benchmark share
price index .KS11 rose 0.5 percent.
The South Korean government expressed concern on Thursday
about the plight of South Korean firms in China since the
deployment was announced. It said it would continue to engage
Beijing in dialogue to ensure activities of South Korean
companies in China are not hindered. urn:newsml:reuters.com:*:nS6N1DM01M
"To be sure, the challenges we face are serious," Foreign
Ministry Spokesman Cho June-hyuck told a news briefing on
Thursday.
Chinese foreign ministry spokesman Geng Shuang said at a
regular news briefing the same day that China opposes all forms
of hacking and is willing to work with other nations to oppose
it.
"As for the guesswork of Lotte, I won't make a comment. But
I think there is no clear answer as to the reason (for the
attack). This is just their guess," Geng said.
