Mexican pension institute suffers massive 5.6GB data breach exposing employee records

ISSSTE's pension system breach demonstrates the catastrophic impact when sensitive government data lacks proper protection controls. The 5.6GB leak potentially exposed personal and financial records of countless Mexican public employees and retirees, highlighting vulnerabilities in critical infrastructure systems.
