Banking Sector Hit by 'External Risks' as Financial Fraud and Data Leaks Spread

Financial fraud incidents in the banking sector are spreading beyond internal employees to external partners, including overseas subsidiaries, third-party contractors, and outsourcing firms. As banks expand digital transformation and international operations, internal controls face new challenges. Prior management systems focused on preventing employee misconduct struggle to detect risks in multi-layered outsourced processes. A major fraud case involved an overseas subsidiary's platform where customer repayment funds were improperly settled, with suspicions of funds being siphoned to separate accounts. Investigations are ongoing. Another incident saw a bank's internal audit missing a 47.85 billion won real estate fraud for months until external inquiries prompted action, highlighting flaws in loan review and collateral verification. Privacy breaches also spread, as seen in a 40.8 billion won fraud case at a major bank where false documents enabled excessive lending.
