2013 Press Release

South Korea cyber attack on anniversary of Korean War

Information related to military forces in Korea and ruling party member personal information at risk

26 June 2013 – Leading global security company, Trend Micro Incorporated (TYO:4704), reports on the wave of targeted cyber attacks on South Korean government and media agencies. The attack began around 9:30am on the day of the Korean War anniversary, with the defacement of the Presidential Office – Cheong Wa Dae’s web site – and extending to the office of Government Policy Coordination.

The defaced website showed a message that read “Great leader Kim Jong-un” - North Korea’s top Leader. The unidentified attacker claims to be part of the hacktivist group, Anonymous, who was involved in recent #OpPetrol and #OpUSA operations, and has posted online what may be the information of 20,000 military personnel.

Website defacement is only the tip of the iceberg; personal identifiable information of the members of the military and government, including the Presidential Office and the ruling Saenuri party, has been compromised.

According to Trend Micro, the attacker took an unprecedented approach in compromising a cloud storage provider to harvest a large number of botnet in a short period of time. By compromising the server which hosted the client installation program (SIMDisk Installer EXE), and its update server, a significant number of PCs are compromised when the cloud storage client program automatically updates. Compared to the previous cyber attack in March, the attacker has gone to a new level; compromising a cloud storage provider rather than simply an update server within the organisation.

Outside South Korea, Trend Micro predicts that cyber attacks will continue to breach critical systems such as application update servers around the world. It warns that application providers must take greater care in securing their update infrastructure and that end users should be cautious of freeware and only install programs from trusted vendors.

To prevent similar attacks, Trend Micro recommends that organisations ensure their critical systems are patched immediately and monitored for unauthorised changes.
