SEOUL, South Korea (AP) - South Korean investigators said Friday they
had mistakenly identified a Chinese Internet address as the source of a
cyberattack that paralyzed tens of thousands of computers at banks and
broadcasters earlier this week. But they said they still believe the
attack originated from abroad.
The error by South Korean
regulators raises questions about their ability to track down the source
of an attack that hit 32,000 computers at six companies Wednesday and
exposed South Korea's Internet security and vulnerability to hackers.
South
Korean investigators said Thursday that a malicious code that spread
through the server of one target, Nonghyup Bank, was traced to an
Internet Protocol address in China. Even then it was clear that the
attack could have originated somewhere else, because such data can
easily be manipulated by hackers. Experts suspect North Korea was behind
the attack.
The state-run Korea Communications Commission said
Friday that the IP address actually belonged to a computer at the bank.
The IP address was used only for the company's internal network and was
identical to a public Chinese address.
"We were careless in our
efforts to double-check and triple-check," KCC official Lee Seung-won
told reporters. "We will now make announcements only if our evidence is
certain."
Commission officials said an analysis of malware and
servers indicates the attack was likely orchestrated from abroad. They
didn't elaborate.
Yonhap news agency, in an analysis Friday,
called the blunder "ridiculous" and said the announcement is certain to
undermine the government's credibility.
Experts in Seoul suspect
North Korea in the attack on broadcasters YTN, MBC and KBS, as well as
Nonghyup and two other banks. Seoul alleges six cyberattacks by North
Korea on South Korean targets since 2009. But the investigation will
take weeks, and officials say they have no proof yet of Pyongyang's
involvement.
South Korean officials say that Wednesday's attacks
appeared to come from "a single organization" but they have yet to
assign blame. North Korea hasn't yet mentioned the shutdown.
South
Korea has set up a team of computer security experts from the
government, military and private sector since to identify the hackers
and is preparing to deal with more possible attacks, presidential
spokesman Yoon Chang-jung told reporters earlier Friday. He didn't
elaborate on the possibility of more attacks.
Determining who's behind a digital attack is often difficult. But North Korea is a leading suspect for several reasons.
It
has unleashed a torrent of threats against Seoul and Washington since
punishing U.N. sanctions were imposed for Pyongyang's Feb. 12 nuclear
test. It calls ongoing routine U.S.-South Korean military drills a
threat to its existence. Pyongyang also threatened revenge after blaming
Seoul and Washington for a separate Internet shutdown that disrupted
its own network last week.
The cyberattack did not affect South
Korea's government, military or infrastructure, and there were no
initial reports that customers' bank records were compromised. But it
disabled cash machines and disrupted commerce in this tech-savvy,
Internet-dependent country.
All three of the banks that were hit
were back online and operating regularly Friday. It could be next week
before the broadcasters' systems have fully recovered, though they said
their programming was never affected.
