AI summary of the source article
Recent North Korean cybercrime campaigns highlight that strong blockchain security is ineffective if attackers compromise the people and systems controlling it. Microsoft documented operations, such as the Contagious Interview campaign, where attackers impersonated recruiters to persuade software developers to execute compromised packages. Additionally, TRM Labs reported that infrastructure attacks, targeting private keys, wallets, and privileged access, accounted for the majority of cryptocurrency theft losses in 2025. To mitigate these risks, crypto organizations and developers must verify professional identities, independently check external code, enforce the principle of least privilege, and strictly separate development and production environments.
