  We compute the albedo (or reflectivity) of electromagnetic waves off the
electron-positron Hawking plasma that surrounds the horizon of a Quantum Black
Hole. We adopt the "modified firewall conjecture" for fuzzballs
[arXiv:hep-th/0502050,arXiv:1711.01617], where we consider significant
electromagnetic interaction around the horizon. While prior work has treated
this problem as an electron-photon scattering process, we find that the
incoming quanta interact collectively with the fermionic excitations of the
Hawking plasma at low energies. We derive this via two different methods: one
using relativistic plasma dispersion relation, and another using the one-loop
correction to photon propagator. Both methods find that the reflectivity of
long wavelength photons off the Hawking plasma is significant, contrary to
previous claims. This leads to the enhancement of the electromagnetic albedo
for frequencies comparable to the Hawking temperature of black hole horizons in
vacuum. We comment on possible observable consequences of this effect.
