The recent six-month infiltration of Drift has sent shockwaves through the crypto industry, still reeling from massive exploits. However, a more pressing question has emerged: what drives North Korea's relentless pursuit of crypto, and why does its approach differ from other state-backed hacking operations?
According to security experts, crypto provides the regime with a vital revenue stream. 'North Korea lacks the luxury of patience,' explained Dave Schwed, Chief Operating Officer at SVRN.
'Under comprehensive international sanctions, they require hard currency to fund their weapons programs. The UN and intelligence agencies have confirmed that crypto theft is a primary funding mechanism for their nuclear and ballistic missile development.' This urgency explains why North Korean hackers carry out large-scale, traceable heists on public blockchains instead of using crypto to quietly evade sanctions. The answer lies in the structural differences between North Korea and other nations.
Russia and Iran have economies that can utilize crypto as a payment rail, but North Korea's exports are almost entirely sanctioned, leaving them with no functioning economy. 'Their exports are almost entirely sanctioned.
They don't have a functioning economy that needs a payment rail. They need direct revenue,' Schwed stated. 'Crypto theft gives them immediate access to liquid value, globally, without needing a counterparty willing to do business with them.' This distinction – crypto as infrastructure versus crypto as a target – separates North Korea from Russia and Iran.
While Russia and Iran use crypto to work around sanctions and fund proxy networks, North Korea operates a state-sponsored heist operation. 'Their targets are exchanges, wallet providers, DeFi protocols, and the individual engineers and founders who have signing authority or infrastructure access,' said Alexander Urbelis, Chief Information Security Officer at ENS Labs. 'The victim is whoever holds the keys or access to the infrastructure that holds the keys.' In contrast, Russia and Iran treat crypto as a means to broader geopolitical ends, targeting elections, energy infrastructure, and government systems.
North Korea's singular focus has led them to adopt tactics more commonly associated with intelligence agencies, including months-long relationship building, fabricated identities, and supply chain infiltration. The Drift campaign is a recent example. 'You're not defending against a phishing email from a random scammer,' Urbelis said. 'You're defending against someone who spent six months building a relationship specifically to compromise one person who has the access you need to protect.' Crypto's architecture makes it an attractive hunting ground, with no safeguards like compliance checks, correspondent bank checks, or settlement delays.
'Once a transaction is signed and confirmed, it's final,' Urbelis said. The Bybit exploit earlier last year moved $1.5 billion in roughly 30 minutes, a pace and scale that would be nearly impossible in the traditional banking system. This finality fundamentally changes the security calculus, making it essential to stop attacks before they happen. While banks operate under decades of regulatory guidance and audit requirements, many crypto projects are still improvising, often prioritizing speed and innovation over governance and controls.
This gap creates an environment where even sophisticated teams can be vulnerable to long-term infiltration tactics. 'This is the hardest operational security problem in crypto right now,' Urbelis said. 'I don't think the industry has solved it.'
