LinkedIn 채용 제안에 숨겨진 백도어

A sophisticated supply chain attack demonstrates how npm's prepare script mechanism can execute arbitrary code automatically upon npm install, bypassing direct code inspection. The attacker leveraged LinkedIn with spoofed identities to establish trust for a code review request containing a hidden backdoor, illustrating how routine developer workflows are weaponized. The case underscores that security consciousness and read-only code analysis tools are more effective defenses than direct code review, and that platforms enabling credential spoofing remain a critical vulnerability in developer recruitment security.
