We identify the states in string theory which are responsible for the entropy of near-extremal rotating four-dimensional black holes in N0ex{0ex}=0ex{0ex}8 supergravity. For black holes far from extremality (with no rotation), the Bekenstein-Hawking entropy is exactly matched by a mysterious duality invariant extension of the formulas derived for near-extremal black holes states.
