Key Insights
- Centralized oversight is being looked into. South Korea is thinking about a government cybersecurity group to manage tasks that are now spread out among different agencies.
- Security checks are growing. Over 2,100 public organizations will be. The science ministry is looking at about 170 private-sector infrastructure places.
- Prevention is getting attention. Officials and cybersecurity experts are focusing on spotting threats, sharing information, doing penetration testing and making sure organizations have more power to act.
South Korea’s cybersecurity changes became more important on November 3 after President Lee Jae-myung told officials to think about a government group because of the $6.3 billion hack at Binance. Lee said that advanced cyberattacks are putting financial stability, national security and important services at risk and he wants better teamwork between government agencies and private companies.
Lee calls for centralized cybersecurity leadership
During a Cabinet meeting on November 3, Lee cited major hacking incidents in South Korea and abroad as evidence of weaknesses in the existing security framework. He argued that responsibilities divided among ministries and agencies limit the country’s ability to coordinate an effective response.
The president specifically mentioned the October 29 Binance incident, where around $6.3 billion in assets was reportedly taken without permission. U.S. Investigators connected this attack to a Korean hacking group showing how serious cybercrime can be for the cryptocurrency industry.
Lee called on officials to look into creating a cybersecurity czar or another government-wide organization that has power to manage security efforts. This new framework would include both institutions and private companies instead of letting each agency deal with threats, on its own.
The government has not yet decided how this new body will be structured, what legal status it will have or what powers it will get. Officials still need to decide if South Korea should create a government agency or form a coordinating committee that works under the existing presidential system.
Emergency Checks Target More Than 2,100 Institutions
The proposal follows wider security reviews across South Korea’s public and private sectors. On October 22, the National Intelligence Service asked more than 2,100 central and local government bodies to inspect their systems using a cybersecurity checklist.

The checks cover internet-facing systems, security monitoring and software updates. The intelligence agency is also examining vulnerabilities across internet-connected systems at critical public infrastructure facilities, with those inspections expected to finish by mid-November.
Meanwhile, the Ministry of Science and ICT is reviewing approximately 170 major private-sector infrastructure facilities. These include telecommunications providers, online platforms and financial institutions, with inspections scheduled for completion by year-end.
South Korea’s current responsibilities remain divided among several authorities:
- The National Intelligence Service oversees cybersecurity at critical public infrastructure.
- The Ministry of Science and ICT manages a part of the private‑sector cybersecurity framework.
- The Financial Services Commission looks after cybersecurity in the sector.
This split makes it hard to coordinate when attacks cross boundaries or hit many industries at once. Recent incidents involving firms, such, as Bithumb, Daishin Securities and Mirae Asset Global Investments have raised the level of scrutiny on the current protections.
AI threats expose weaknesses in existing defenses
Lee said that advances in intelligence are making cyberattacks more complicated and more common. Because of this regular security checks and responses after a break-in may no longer be enough to keep things safe.
He called for a prevention-focused system that identifies warning signs early, shares threat intelligence quickly and enables agencies to act before damage spreads. He also demanded comprehensive reviews of critical infrastructure serving the public.
The priority areas include finance, energy, telecommunications and information and communications systems. Lee urged officials to identify vulnerabilities and overhaul outdated security arrangements to address emerging attack methods.
Cybersecurity specialists have also questioned whether existing oversight delivers meaningful protection. Youm Heung-youl, professor emeritus of information security at Soonchunhyang University, said the government must clarify the proposed organization’s purpose before choosing its structure.
He identified legislation and political agreement as potential requirements for a new agency. Alternatively, strengthening the presidential National Security Office’s coordinating role could offer another route.
Youm stressed that any committee must possess real authority over budgets, personnel and information sharing. Without those powers, a new organization could struggle to influence agencies with separate responsibilities.
Dongguk University’s Graduate School of Information Security professor Hwang Suk-jin said there would be shortcomings in the ministry-by-ministry supervision against attacks using AI. He called for frequent penetration testing and on-site testing rather than companies testing themselves.
National security and digital competitiveness at stake
The cybersecurity debate goes beyond cryptocurrency exchanges. Financial services, telecommunications networks and energy infrastructure are the backbone of economic activity. When these systems are attacked it becomes a national security issue.
Lee noted that it is important for South Korea to build world-class cybersecurity capabilities and the country Technical defenses and institutional reforms should therefore go hand-in-hand in order to go stronger.
The incident at Binance highlights the need for timely threat detection and cross-jurisdictional response efforts for cryptocurrency enterprises. The framework, however, is still subject to review in South Korea, and the ultimate success of this will rely on its power, resources and mode of application.
Lee’s order represents a step towards more integrated prevention, not reactive responses to attacks. The upcoming security assessments and organizational decisions will play a role in determining if the South Koreans can fill current security gaps and improve their systems against the more complex cyber threats.
