Not sure if Meltdown is the same, but I read that Spectre can recover memory at about 10kb/sec. So it wouldn't be very efficient to scan the entire memory for a known pattern.
I suppose if there was an exploit targeted at a specific program, it would be possible to work out what location the secrets are stored in?
