3. Banco Central Burglary (2005, Brazil)

In August 2005, a group of criminals in Brazil spent three months meticulously digging a tunnel from a rented house to the Banco Central’s vault in Fortaleza. The tunnel, approximately 78 meters long and 2 meters high, was reinforced with steel and timber to prevent collapse. On the night of the heist, they accessed the vault and escaped with about $70 million in cash. The audacity and ingenuity of the crime shocked Brazil, leading to widespread media coverage and discussions about security vulnerabilities in financial institutions.
