Lost both GPS L/R signals on about a 12 mile intercept to final 33R.  Followed the ILS to touchdown and when exiting the runway; both GPS signals came back online. Not knowing what the issue was; an ACARS maintenance record was sent. Two days later; it was made known that GPS signals are being jammed in the area of ICN (RKSI) airport; thus prompting this report.
An air carrier arriving RKSI reported the loss of GPS signals most probably due to jamming so the ILS was flown to touchdown.
