'온라인 주민번호' CI 대규모 유출 반년... 개선 논의는 '지지부진'

South Korea's CI identity verification system faces a critical security gap that regulators have failed to address for six months despite major breaches. CI's structural flaw—operating as a permanent, master key across financial and commercial platforms—means each compromised record can trigger cascading attacks affecting shopping, loyalty programs, and entire financial portfolios. The regulatory body's inability to decide on concrete reforms like CI2 transition or validity limits leaves millions of users in a state of indefinite vulnerability.
