Summary
The Suspicious Signal site's goal is to destroy a structure that, by default, is invulnerable. By hacking (data) 3 different locations at the same time, the structure becomes attackable for 90 seconds, while the hacked location re-arm. The cycle has to be repeated until the structure has been destroyed.
The objective has to be completed while being attacked by a set of NPCs.
Upon completion (the structure has been destroyed), with 5 participating pilots, each fleet member receives a payout of 15,486,410 isk for a total of 77,432,050 isk. On top of that, an average of 2,000,000 isk in acquired hacking loot which can be sold to NPC buy-orders.
