Zip, I think the situation is the other way around.
I suspect this is UT's old boss who has finally figured out that the reason the data keeps getting small random changes and sending naughty emails to the boss is to do with a few trojans and backdoors UT left in the system before he was dumped.
The obvious solution is to give UT a "consultancy" to "refresh" the system. I think $100,000 would be industry standard.
