i got this message: Dread Perp attacks You with MLK-Iz Mining Laser for 10 damage
4 times and i taked 40 damage all in all...
And i was in "Nodus Secundus" a "CONS-protected area" is proteckted != save?
That is correct. Only GPD sectors are "completely safe", CONS sectors contain unfriendly pirates that shoot at you.
As explained in the manual

GPD protects their sectors from pirates and criminals.Those sectors are mostly safe from both NPCs (PvE) and players (PvP).

CONS protects their sectors from player pirates (PvP), but they don't get involved in player-vs-npc (PvE) fights.
