Could be any number of things, many of them totally unrelated to LFS, could be a total coincedence too.
For some reason cybercon are connecting to your machine, but it doesnt actually mean anything, heck I probably get 10,000 portscans from different ip's everyday.
If the IP (cybercons) wasnt on PG's blacklist you wouldnt have seen it, there must be some reason there range is on PG's blacklist, but I dont know why.
To be perfectly honest I wouldnt worry about it that much, LFS doesnt contain spyware, heck you could have even been running something in the background that has connected to that ip, or you could even have a virus/spyware infection.
