The recent six-month infiltration campaign targeting Drift has left the crypto industry reeling, prompting a deeper question: what drives North Korea's persistent focus on 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, enabling it to stay afloat. '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, with crypto theft serving as 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, rather than quietly using crypto to evade sanctions like other state actors. The answer lies in the structural differences between North Korea and other nations. 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.

'Their exports are almost entirely sanctioned, and they don't have a functioning economy that needs a payment rail,' Schwed noted. 'They need direct revenue, and 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 operates a state-sponsored heist operation, targeting exchanges, wallet providers, DeFi protocols, and individual engineers and founders with signing authority or infrastructure access.

'Their targets are those who hold the keys or access to the infrastructure that holds the keys,' said Alexander Urbelis, chief information security officer at ENS Labs. Russia and Iran, by contrast, 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 Korea's singular focus has driven its operatives 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 of this approach.

'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 none of the safeguards that exist in traditional finance, such as compliance checks, correspondent bank checks, settlement delays, and the possibility of reversing fraudulent transfers.

'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 an attack before it happens. 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.'
