I can't speak for the specificity of parent's "evil maids" phrase but the concept of an "Evil maid" is used in security scenarios.
A maid tends to be an example of a person who's mostly a stranger, but is given unmonitored access to your most private spaces for prolonged periods of time. So they theoretically become a good vector for a malicious actor to say "hey I'll give you $$ if you just plug in this USB drive in his bedroom laptop next time you're cleaning his house" - it's often used in the scenario of "ok what if someone has physical access to your resource for a prolonged period of time without you noticing? what are your protections there?"
I wonder if that's what OP meant? :-)
"Evil maids" (example): I put my laptop into a safe, seal the safe, seal the room, go to breakfast. On return, I see there was cleaning (not the usual time, I know the hotel), the cleaner looks strangely confused, the seal on the safe is detached (that is often done by applying ice; adhesive hardens, seal goes off). This level of paranoia was not my norm. Had to learn these tricks cause problems happened (repeatedly). In fact, I frequented that hotel, knew customs and the staff, so noticed irregularities.
And what does this have to do with the price of tea in China?
Ah right, thanks! But it seems he meant literal evil maids. Which I guess count as the figurative kind too.
