CHIMERA Attack Grades, A0–A8

A bot draws mouse paths using smooth mathematical curves (Bezier interpolation) with fabricated overshoot-and-correct motion, rather than real human movement.

One previously recorded genuine session, replayed unchanged - identical timestamps, identical path, identical everything.

A real recorded mouse trajectory paired with independently generated (synthetic) keystrokes - only one channel is genuine, the other is fabricated.

A recorded genuine session with its timing uniformly sped up, slowed down, or jittered, to avoid an exact-timestamp match against A2-style detection.

3+ different real human sessions, cut at natural pause points and geometrically stitched together - mouse movement from one donor, keystrokes overlaid from another, retimed to blend seamlessly.
