U.S. Warns of Threat to Financial Industry Posed by North Korean Cyberattacks

The Advisory notes that to avoid falling victim to North Korean cyberattacks, people can take the following steps, among others:

• Raise awareness of the North Korean cyber threat. OFAC recommends that organizations highlight the gravity, scope and variety of malicious cyber activities carried out by North Korea to raise awareness of the threat in the public and private sectors. Further, awareness raising will promote adoption and implementation of preventive and risk mitigation measures. For private-sector companies, this means incorporating a more sophisticated understanding of the North Korean cyber threat into risk assessments and planning as well as management discussions about evolving risks for governance purposes.
• Share technical information of the North Korean cyber threat. Information sharing — across the private and public sectors — can assist in the detection and defense against North Korean cyber threats. Technical information sharing enables organizations to enhance their cybersecurity networks and systems. The Cybersecurity Information Sharing Act of 2015 permits nonfederal entities to share cyber threat indicators and defensive measures with federal and nonfederal entities and provides some limited liability shields from privacy claims where entities share information pursuant to certain protocols.²
• Implement and promote cybersecurity best practices. Adopting cybersecurity best practices helps to create a secure and resilient international cybersecurity infrastructure. The Advisory recommends that financial institutions take independent steps to protect against the North Korean cyber threat. For example, organizations can segment networks to minimize risk, maintain regular backup copies of data, undertake awareness training on common social engineering tactics and develop more comprehensive incident response plans. Cybersecurity best practices are discussed further below.
• Notify law enforcement. Organizations should notify law enforcement when malicious cyber activity is suspected. Timely notification to law enforcement can expedite investigations and increase the chances that stolen assets can be recovered.
• Strengthen anti-money-laundering (AML), countering the financing of terrorism (CFT) and counter proliferation financing (CPF) compliance. Countries should implement risk mitigation measures in line with the Financial Action Task Force (FATF) standards on AML, CFT and CPF. FAFT has called for all countries to apply countermeasures to protect against North Korean cyberattacks, with special attention to financial institutions with business relationships with North Korea or North Korean companies. The U.S. government expects financial institutions and other payment processors to engage in transaction monitoring, customer due diligence and suspicious activity reporting and notes that platforms operating with potential anonymous payment activity and outside of compliance with AML expectations are of particular concern.

The Advisory’s recommendations are in accord with general cybersecurity regulations that govern financial institutions. The Gramm-Leach-Bliley Act requires financial institutions to develop written information security plans. Security plans must include a comprehensive safeguards program that is regularly monitored and tested and a risk assessment plan that can be used to appropriately modify cybersecurity practices.³ Financial regulators have in recent years have also stressed the important of business continuity and disaster recovery planning, critical to mitigating ransomware risks, in examinations. Companies can also look to the National Institute of Standards and Technology framework for guidance on how to best monitor, detect and prevent cyber threats.⁴

This Advisory forms part of OFAC’s current focus on North Korea and follows OFAC’s publication of amended North Korea Sanctions Regulations (31 C.F.R. Part 510) on April 10, 2020, incorporating into the regulations the blocking and correspondent banking sanctions present in the North Korea Sanctions and Policy Enhancement Act of 2016, as amended by the Countering America’s Adversaries Through Sanctions Act and the National Defense Authorization Act for Fiscal Year 2020.

Individuals and entities must take steps to ensure that they do not engage in any activities that support North Korea’s cyberattacks, including processing related financial transactions, or risk violating both U.S. and United Nations sanctions. If OFAC determines that a foreign financial institution has facilitating any significant transaction in connection with the government of North Korea, that institution may face secondary sanctions, including losing the ability to maintain a correspondent account in the United States or designation as a Specially Designated National. Maximum civil penalties for sanctions violations are the greater of $307,922 or twice the value of the transaction, per violation.⁵
