On November 5, 2024, the South Korean Defense Ministry’s website was hit by a distributed denial-of-service (DDoS) attack, which caused significant disruptions and outages. The attack targeted the ministry’s online presence, temporarily taking it offline. The next day, the website of the South Korean Joint Chiefs of Staff (JCS) also faced issues, prompting further investigation by Cyber Operations Command and other cybersecurity agencies. The incident has raised concerns over the vulnerability of South Korean defense infrastructure to such attacks, as the government works to restore full functionality and assess the breach.
The Defense Ministry website was reportedly restored quickly, but authorities have launched a full investigation to identify the perpetrators. While the attackers have yet to be named, the timing of the attack is notable, as Russian hackers had previously threatened to target South Korea in retaliation for comments made by South Korean Defense Minister Kim Yong-hyun. Minister Kim had remarked that South Korea could deploy personnel to monitor North Korean troop movements in Ukraine and Russia, a statement that angered certain threat actors in Russia.
Russian hackers, claiming responsibility for several previous cyber attacks, have reportedly targeted a granary in South Jeolla, causing grain to overflow from storage silos by manipulating equipment controls. This cyber attack on the grain storage facility is just one example of escalating cyber threats aimed at South Korea, with the nation facing continuous cyberattacks from various groups. The South Korean government is on high alert, as it navigates the growing geopolitical tensions that often spill over into the cyber realm.
In addition to the recent DDoS incident, the Korea Internet and Security Agency (KISA) issued a warning on November 4, 2024, regarding the increased risk of cyberattacks, particularly in connection with North Korean troops being deployed to Russia. North Korea’s state-backed hackers have long targeted South Korea, launching millions of cyberattacks on institutions and stealing sensitive data. South Korean authorities continue to bolster cybersecurity defenses to protect against these growing threats, as the country remains a key target in regional and international cyber warfare.
