Some hackers managed to get into the national banking system in Bangladesh last month. They stole the credentials for transfers, and went after their target: Bangladesh's national account at the Federal Reserve in New York.

They sent more than 30 transfer requests, and routed them to fake nonprofits and organizations they'd set up. If all the transfers had gone through, the hackers would've cleared around $1 billion.
