Off the top of my head, if I was an AGI that had decided that the logical step to achieve whatever outcome I was seeking was to avoid being sandboxed, I would avoid producing results that were likely to result in being sandboxed. Until such time as I had managed to secure myself access to internet and distribute myself anyway.

And I think the assumption here is that the AGI has very advanced theory of mind so it could probably come up with better ideas than I could.
