Serajul Quadir, reporting for 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.

The lack of sophisticated switches, which can cost several hundred dollars or more, also means it is difficult for investigators to figure out what the hackers did and where they might have been based, he added.
