Fatal Attractor

Fatal Attractor is anti-personnel program nasty version of Hellhound credited to the infamous Waycon Kidd. Legend has it, the Kidd ended up as the loser in a romantic triangle, and used this duplicate of his ex-girlfriend to eliminate his netrunning rival.

The Fatal Attractor operates much like a Hellhound; it lurks around Data Fortresses waiting to pounce on intruders. However, instead of immediately attacking, it appears as a very attractive female netrunner who offers to help the intruder break into the system. The Fatal Attractor will cheerfully accompany the 'runner for 1D6+1 turns, then attack as a Hellhound.
