A six-month infiltration campaign by North Korean hackers at Drift has sent shockwaves through the crypto industry, still reeling from massive exploits. But the bigger question on everyone's mind is: why does North Korea keep targeting crypto, and what makes its approach so different from other state-backed hacking operations? According to security experts, the answer lies in the fact that crypto provides the regime with a vital revenue stream.
'North Korea is under comprehensive international sanctions and needs hard currency to fund its weapons programs,' said Dave Schwed, chief operating officer at SVRN. 'Crypto theft is a primary funding mechanism for their nuclear and ballistic missile development.' This urgency is what drives North Korean hackers to carry out large-scale, traceable heists on public blockchains, rather than using crypto to evade sanctions like other state actors.
The reason, Schwed argues, is structural: while countries like Russia and Iran have functioning economies and use crypto as a payment rail, North Korea has almost nothing to sell and needs direct revenue. 'Crypto theft gives them immediate access to liquid value, globally, without needing a counterparty willing to do business with them,' Schwed said. This distinction - crypto as infrastructure versus crypto as a target - is what separates North Korea from other state-sponsored hacking operations. While Russia and Iran use crypto to route money and fund proxy networks, North Korea is running a state-sponsored heist operation, targeting exchanges, wallet providers, DeFi protocols, and individual engineers and founders.
'Their targets are whoever holds the keys or access to the infrastructure that holds the keys,' said Alexander Urbelis, chief information security officer at ENS Labs. The crypto industry's own architecture makes it a uniquely attractive hunting ground for North Korean operatives, who have adopted tactics more commonly associated with intelligence agencies, such as months-long relationship building and supply chain infiltration. The Drift campaign is just the latest example.
'You're not defending against a random scammer, you're defending against someone who spent six months building a relationship to compromise one person with access,' Urbelis said. The lack of safeguards in crypto, such as compliance checks and settlement delays, makes it a high-risk environment.
'Once a transaction is signed and confirmed, it's final,' Urbelis said. This finality fundamentally changes the security calculus, making it essential to stop attacks before they happen. However, the crypto industry's emphasis on speed and innovation often prioritizes governance and controls, creating 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.'
