A regional bank operating in several cities recently found account-balance discrepancies during routine audits. The issues appeared across multiple branches, leading to an internal investigation. Further analysis revealed that an individual with prior authorization had changed financial records. The investigation determined that a former employee, whose credentials were not deactivated after departing the company, retained full control of critical systems. This lapse enabled the person to alter transactional data, resulting in inaccurate financial reports and possible damage to the bank’s reputation. The former employee’s changes were deliberate and affected customer accounts. Although the individual was no longer employed, the failure to revoke their permissions allowed these changes to happen without barriers. Which cybercrime classification best fits this incident?
