This alarming trend underscores the evolving tactics of nation-state actors leveraging cybercrime as a strategic tool rather than purely for financial gain.

According to TRM Labs, the February Bybit hack alone, attributed to North Korea, accounted for $1.5 billion, marking the largest crypto heist in history.
North Korea-linked hackers stole $1.6B of $2.1B crypto in H1 2025, with the Bybit breach reshaping the crypto security landscape amid rising nation-state threats.
North Korea Emerges as Leading Nation-State Threat in Crypto Hacks
The first half of 2025 witnessed a record-breaking $2.1 billion in cryptocurrency thefts, with North Korean-sponsored actors responsible for approximately 70% of these losses. This surge, documented in TRM Labs’ report “H1 2025 Crypto Hacks and Exploits: A New Record Amid Evolving Threats,” highlights the increasing sophistication and scale of attacks originating from state-backed groups. The report emphasizes North Korea’s entrenched role as the most prolific nation-state threat actor within the crypto ecosystem, leveraging cybercrime not only for financial gain but as a critical instrument of statecraft.
The Bybit Hack: A Landmark Incident in Crypto Security
Central to the record thefts was the February 2025 breach of Bybit, a Dubai-based crypto exchange, where hackers stole nearly $1.5 billion in Ethereum and related assets. Investigations revealed that the breach stemmed from a compromised developer laptop interacting with a malicious docker project, exposing vulnerabilities in multi-signature wallet security. Safe, the multi-signature wallet provider, confirmed that a high-level developer’s workstation was the attack vector. TRM Labs and U.S. authorities have attributed this exploit to North Korean threat actors, underscoring the strategic targeting of infrastructure to gain control over private keys and seed phrases.
Strategic Cybercrime: Nation-State Weaponization of Crypto Theft
TRM Labs’ analysis indicates a paradigm shift in crypto-related cybercrime, where attacks are increasingly symbolic or strategic rather than purely financially motivated. The report notes that 80% of the losses in 2025 resulted from infrastructure attacks, highlighting the growing focus on compromising critical security components such as private keys. This evolution reflects how nation-states like North Korea are weaponizing crypto theft to fund geopolitical objectives, including sanctioned programs, while simultaneously destabilizing the global crypto market.
Implications for Crypto Security and Regulatory Response
The unprecedented scale of these hacks has prompted calls for enhanced security protocols within crypto exchanges and wallet providers. Industry experts advocate for robust multi-factor authentication, continuous monitoring of developer environments, and stricter access controls to mitigate risks associated with insider threats and compromised credentials. Furthermore, regulatory bodies are increasingly scrutinizing crypto platforms to enforce compliance with cybersecurity standards, aiming to curb the influence of nation-state actors in the digital asset space.
Conclusion
The first half of 2025 has set a new benchmark for crypto theft, driven predominantly by North Korean state-sponsored hackers employing sophisticated infrastructure attacks. This trend signals a critical juncture for the cryptocurrency industry, emphasizing the need for heightened security measures and international cooperation to address the strategic weaponization of crypto crime. Stakeholders must prioritize resilience and transparency to safeguard digital assets against evolving nation-state threats.
