It would be interesting to hear from the HN community, people with Samsung laptops, if they've had this happen, or if they check now, if this keylogger is discovered.
Currently on an R720 and I've no SL folder, either.
I've poked around various locations on the machine and run some scans with a number of different tools, but I've discovered nothing untoward, as yet.
My attestation is somewhat of an irrelevance, however, as I've no way of accurately replicating the environment in which Mr Hassan carried out his research. It looks as though I shall simply have to wait and see how this all plays out over the coming days.
Given US law enforcement's use of surveillance on individuals with certain foreign ties, in order to faithfully replicate this it might require someone named "Mohamed" unfortunately.
