North Korea were caught cheating in 1991 and given a 15 year ban until 2007. They were also disqualified from the 2010 IMO because of weaker evidence of cheating. Given this, an alternative hypothesis is that they have also been cheating in other years and weren’t caught. The adult team leaders at the IMO do know the problems in advance, so cheating is not too hard.
The Danish team leader (the closest source to these events i have talked to) seems to (personally) believe the cheating allegations in 2010 or at least that the evidence was insufficient. Also note their non participation in 2017 and 2018 for reasons not known to me and in 2020 likely because the event was online
