Japan ties exported PCs to Internet attacks
Japanese police suspect a consignment of 1,843 used computers and monitors allegedly exported to North Korea could have been used in a 2009 week-long attack on a handful of South Korean and U.S. websites.
The computers, allegedly exported in violation of Japanese sanctions, were shipped to the Pyongyang Informatics Center (PIC), a unit of the state-run Korea Computer Center (KCC), on June 18, 2009, the Yomiuri Shimbun reported quoting “investigation sources.”
Less than a month later on the July 4 weekend, a distributed denial of service (DDOS) attack targeted 27 South Korean and U.S. websites.
DDOS attacks work by harnessing the power and bandwidth of multiple PCs to flood a website with traffic so it becomes overloaded. At least 20,000 PCs were used in the attacks, the majority of which were infected with malicious software (malware) that lay dormant before being issued a command to attack.
Because of the scale of the attack and the bandwidth required, it’s unlikely the PCs exported from Japan — if indeed they were used in the attacks — were on the front line of the attack.
In fact, it’s difficult to see how investigators have managed to pin those attacks on these computers. Japanese media reports don’t provide any detailed information.
The reports do say that Lee Soon Gi, the president of Tokyo-based used PC dealer Popura-tec (website, left), exchanged e-mail messages with Korea Computer Center officials which “suggest the existence of a hacker unit in Pyongyang.”
KCC is one of North Korea’s top computer knowledge centers and has long been suspected of involvement in a number of illicit online activities. It also runs the Naenara website.
Lee is believed to have met senior PIC officials before exporting the 1,843 units as he traveled to North Korea from March to April 2009 with a visiting group of members of the Zainichi Korean Science and Technology Association, an affiliate of the pro-Pyongyang General Association of Korean Residents in Japan. – Yomiuri Shimbun, March 13, 2012.
The Korean Association of Science and Technology in Japan was raided by police earlier this month as part of their investigation.
On Monday Japanese prosecutors filed charges against Lee on suspicion of violation of the country’s Foreign Exchange and Foreign Trade Law. Lee was previously arrested on suspicion of shipping 100 laptop PCs to North Korea in February 2009. In total, he allegedly exported more than 7,200 PCs to North Korea in previous years, reported the Yomiuri Shimbun.

Kwangmyong, North Korea’s online information service, has been upgraded. The network serves scientific and technological information and has been expanded with a new search function that includes a translation function, according to a recent article on Naenara, the website of Pyongyang’s Korea Computer Center. The article doesn’t go into great date on what exactly is new,…

When he wasn’t taking stunning panorama photographs around Pyongyang, Singapore-based photographer Aram Pan had time to visit this year’s Pyongyang Spring International Trade Fair (평양봄철국제상품전람회). The fair was twice as big this year as it had been in 2013 according to state media, and it’s easy to see why when you watch a 3-minute video shot by Pan. The…

The U.S. Air Force didn’t waste much time in putting into use two high-tech drones that it moved from Guam to Japan earlier this month. The drones arrived at Misawa Air Base in northern Japan on May 24 and the first operational mission was flown on June 6, according to information released Friday by the U.S. Air…

The U.S. Air Force’s Global Hawk drone landed in Japan for the first time on Saturday. The aircraft is one of the most advanced unmanned craft in the world and is typically used for surveillance and eavesdropping missions from its perch at around 60,000 feet — well above the level of commercial aircraft but lower than the…

Poor Microsoft. It seems North Korea doesn’t like the traditional Windows-look anymore. The latest version of the country’s home-grown operating system, Red Star Linux, has been restyled and ships with a desktop that closely resembles Apple’s Mac OSX. The previous version was based on the popular KDE desktop that mimicked that of Windows 7. Red…

One of the surprises in North Korea’s recently-launched Samjiyon (삼지연) tablet was the inclusion of Angry Birds, the globally-popular game that involves shooting animated birds to destroy structures and animated pigs. In July, when I was reviewing the Samjiyon, I contacted game-maker Rovio to ask about its inclusion in the device. Despite several attempts to get comment,…

One of the most interesting questions surrounding North Korea’s Samjiyon tablet is its source. State media reports not withstanding, the tablet is almost certainly not made in North Korea — the country just doesn’t have the electronics manufacturing capability to design products like tablet computers from the components up. And anyway, why bother? Companies in Taiwan…

In the last year, state media has highlighted three different tablet computers that are now, according to the reports, available in the country. The latest of these, the Samjiyon (삼지연), is also on sale to foreigners and one of the tablets…
