Uh no they didn't, this guy has said this is what he was told on a phone call. Samsung has not released a public statement saying this is what they actually do.

Without confirmation from anyone else that has a Samsung laptop (have just checked my brother's bought 2 months ago and found nothing) this really should be taken with a grain of salt.

I stand corrected, and should have read the followup article.

I don't think the Samsung "confirmation" brings me to 50% confidence that Samsung actually was logging and capturing people's keystrokes, though.

I would still like to see what the keylogger is actually doing - storing, transmitting, what?
