North Korean Hackers Launch Audacious Crypto Heist Through US Tech Firm: Cybersecurity Concerns Skyrocket

In late June, a North Korean government-backed hacking group targeted an American IT management company, JumpCloud, based in Louisville, Colorado. The hackers exploited their access to JumpCloud's systems to infiltrate fewer than five of its clients, which were later confirmed to be cryptocurrency companies. This article sheds light on the incident and its implications, highlighting the growing threat of "supply chain attacks" in the realm of cybersecurity and cryptocurrency.

The Hack and its Consequences

JumpCloud, a company specializing in IT network administration, fell victim to a cyberattack that allowed hackers access to sensitive information. While JumpCloud did not disclose the names of the affected clients, cybersecurity firms CrowdStrike Holdings and Mandiant, assisting JumpCloud and one of its clients, respectively, identified the attackers as being known for focusing on cryptocurrency theft.

The hackers involved were affiliated with "Labyrinth Chollima," a notorious group operating on behalf of North Korea. This group, which is linked to North Korea's Reconnaissance General Bureau (RGB), the primary foreign intelligence agency, is recognized for carrying out daring and disruptive cyber intrusions. They have previously executed supply chain attacks, leveraging access to one target to penetrate and exploit others further downstream.

The "Supply Chain Attack" Tactic

A supply chain attack involves targeting a company or entity with the intention of gaining access to their network and using it as a springboard to attack other organizations further along the supply chain. In this case, the hackers breached JumpCloud, not necessarily for its own data, but rather to gain a foothold within its client base, which consisted of cryptocurrency companies.

This tactic provides attackers with several advantages:

  1. Broader Access: Supply chain attacks allow hackers to reach multiple victims through a single point of entry. In the case of cryptocurrency companies, the potential rewards can be significant, as these organizations often hold substantial amounts of digital assets.
  2. Camouflage: By infiltrating a reputable company like JumpCloud, the hackers can operate unnoticed for an extended period, reducing the risk of detection and mitigation.
  3. Trust Exploitation: Cryptocurrency companies often trust their IT management service providers implicitly, making it easier for hackers to exploit this trust for nefarious purposes.

North Korea's Escalating Cyber Warfare

The recent attack on JumpCloud exemplifies North Korea's intensifying cyber warfare capabilities. Traditionally, North Korean cyber spies targeted digital currency firms directly, seeking to pilfer cryptocurrencies piecemeal. However, the shift towards supply chain attacks suggests that they now seek more significant impact and financial gain.

North Korean hackers have been involved in various high-profile attacks, including the WannaCry ransomware attack in 2017, which affected hundreds of thousands of computers worldwide. Despite ample evidence, including reports from the United Nations, North Korea continues to deny involvement in such activities.

The Threat to Cryptocurrency Companies

The targeting of cryptocurrency companies presents a severe threat to the crypto industry. Unlike traditional financial institutions, cryptocurrencies operate on decentralized networks, offering pseudonymity and potentially limited recourse for victims of cybercrime. Here's why cryptocurrency companies are particularly attractive targets for hackers:

  1. High-Value Assets: Cryptocurrency companies hold significant digital assets that, when stolen, can result in massive financial losses.
  2. Lack of Regulation: The decentralized nature of cryptocurrencies often means that there are fewer regulatory measures in place compared to traditional financial institutions, making them more vulnerable to cyberattacks.
  3. Anonymity: Cryptocurrency transactions are inherently more challenging to trace than traditional financial transactions, providing cybercriminals with an added layer of anonymity.

Preventing Future Attacks

Defending against supply chain attacks and securing the cryptocurrency industry requires a multi-faceted approach:

  1. Strengthening Cybersecurity Measures: Companies, particularly those handling cryptocurrencies, must invest in robust cybersecurity measures, including network monitoring, encryption, and multi-factor authentication to protect sensitive data.
  2. Vigilance and Detection: Regular security audits, threat hunting, and incident response planning are essential to detect and respond to potential breaches promptly.
  3. Public-Private Collaboration: Governments and private entities should collaborate to share threat intelligence, enhancing the ability to identify and prevent cyberattacks.
  4. User Education: Companies should educate their employees and clients about potential cyber threats, promoting good cybersecurity practices, such as strong password management and recognizing phishing attempts.


The cyberattack on JumpCloud and its subsequent targeting of cryptocurrency companies underscore the growing threat posed by North Korean hacking groups. Their shift towards supply chain attacks demonstrates their increasing sophistication and ambition. The incident serves as a critical reminder for both the private sector and governments to remain vigilant and proactive in defending against cyber threats, especially in the context of the cryptocurrency industry. By enhancing cybersecurity measures, fostering public-private collaboration, and raising awareness, we can better protect against these cyber threats and safeguard the future of digital assets and online financial systems.
