If you thought cutting corners might not be so bad, check out this news report from the BBC:
Hackers managed to steal $80m (£56m) from Bangladesh's central bank because it skimped on network hardware and security software, reports Reuters.
The bank had no firewall and used second-hand routers that cost $10 to connect to global financial networks.
I can understand wanting to save on some hardware costs. But no firewall? For a bank? Someone didn't do their job. It could've been much worse had it not been for human error on the part of the thieves:
A spelling mistake in one of the transfer orders alerted bank staff and meant the hackers only managed to steal $81m.
