Why has the prime illuminati bank in the world N M Rothschild & Sons never been hacked?

Do they even use computers? Is it all off books? And if so who is the go-between for them?

I always found it curious there wasn't a single mention of the Rothschild banks in WikiLeaks. Those banks don't seem to leave much of a electronic trace in their dealings.

(there was always this rumour in London that the regional N M Rothschild & Sons Ltd offices in England were regional offices for MI6 in the event of London being nuked.)
