Second-hand, $10 switches left Bangladesh open to cyber heist

Wondered how come hackers managed to siphon off nearly $1 billion from Bangladesh's central bank? This is the answer, according to Reuters:

Bangladesh's central bank was vulnerable to hackers because it did not have a firewall and used second-hand, $10 switches to network computers connected to the SWIFT global payment network, an investigator into one of the world's biggest cyber heists said.

Truly an incredible central banking story!
