More bad news this week coming out of the SWIFT messaging system hacks. New banks are being targeted and an unspecified number have experienced incidents. In the case of the $81 million dollar Bangladesh Bank breach, the intrusion started with a vulnerable network switch.
The bank used “second-hand networking gear” which led to the compromise. Second-hand anything in your security and networking infrastructure is probably not a great idea and not keeping infrastructure patched is a recipe for trouble.
