Unisys in the US could become the subject of an investigation following attacks on Homeland Security Department computer systems, which the computer company built. 

Because Unisys has been contracted, for $1,7-billion, to build the systems, there are calls that it be held responsible for the attacks.
Apparently there have been hundreds of hacks, many of them not noticed for some months and then mis-reported.
Now, there are calls for the contractor – Unisys – to be held accountable since it was responsible for maintaining network security.
It hasn't yet been decided whether an investigation will be launched.
