A six-month-long North Korean infiltration campaign targeting Drift has sent shockwaves through the crypto industry, which is still reeling from massive exploits. However, this incident raises a crucial question: why does North Korea continue to target the crypto space, and what makes its approach so distinct from other state-sponsored hacking operations? According to security experts, the answer lies in the fact that crypto provides the regime with a vital revenue stream, enabling it to stay afloat.
'North Korea lacks the luxury of patience,' explained Dave Schwed, Chief Operating Officer at SVRN and founder of the cybersecurity masters program at Yeshiva University. 'Under comprehensive international sanctions, they require hard currency to fund their weapons programs.' The UN and multiple intelligence agencies have confirmed that crypto theft is a primary funding mechanism for North Korea's nuclear and ballistic missile development. This sense of urgency explains why North Korean hackers carry out large-scale, traceable heists on public blockchains, rather than quietly using crypto to evade sanctions like other state actors.
The reason, Schwed argues, is structural. Unlike Russia and Iran, which have functioning economies and use crypto as a payment rail, North Korea has almost nothing to sell, with its exports largely sanctioned. 'They need direct revenue,' Schwed said. 'Crypto theft gives them immediate access to liquid value globally, without requiring a counterparty willing to do business with them.' This distinction - crypto as infrastructure versus crypto as a target - sets North Korea apart from Russia and Iran.
While Russia and Iran use crypto to work around sanctions and fund proxy networks, North Korea is running a state-sponsored heist operation. 'Their targets are exchanges, wallet providers, DeFi protocols, and individual engineers and founders with signing authority or infrastructure access,' said Alexander Urbelis, Chief Information Security Officer at ENS Labs and a professor of cybersecurity at King's College London. 'The victim is whoever holds the keys or access to the infrastructure that holds the keys.' In contrast, Russia and Iran treat crypto as incidental, a means to broader geopolitical ends.
'Russia targets elections, energy infrastructure, and government systems, while Iran goes after dissidents and regional adversaries,' Urbelis said. 'When either of them touches crypto, it's to move money, not to steal it from the ecosystem.' North Korean operatives have adopted tactics more commonly associated with intelligence agencies than criminal hackers, 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 with the access you need to protect.' Crypto's architecture makes it an attractive hunting ground, as it lacks the safeguards present in traditional finance, such as compliance checks and 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, particularly 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.'
