There really isn't a whole lot we can do about attacks like that,
I see the time-share salesmen are spewing their bullshit in another thread.
I'll repost here what I posted nearby:
https://bitcointalk.org/index.php?topic=1068157.0Easily preventable on two levels:
1) collocate your own equipment in a remote data center. The customer service staff will simply have no access to it besides being able to press buttons on the box.
2) use non-commodity hardware like Oracle SPARC or IBM POWER or HP Integrity/Itanium. Then even if they manage to steal it they most likely will not be able to get the data off of it without specialized assistance.
Also, don't run Linux on those machines, but their native OS: Solaris, AIX, HP/UX respectively.
