By embedding malicious code into the cryptographic backbone of blockchain networks, hackers are effectively turning one of the most tamper-resistant technologies into a resilient delivery system for cyberattacks. For cybersecurity teams, the findings highlight a growing challenge: the same decentralization that secures digital currencies is now being exploited to hide and distribute malware beyond the reach of any central authority.
Hackers aligned with North Korea are using public cryptocurrency blockchains to conceal and distribute malicious code, adopting a technique researchers describe as a new form of untouchable online hosting.
The approach reuses the design of blockchain smart contracts, a system intended for transparency and trust, to store and deliver malware in ways that are nearly impossible to disrupt.
