It comes three weeks after the hacker first published a series of photos of sports stars and celebrities, including Solo, Olympic gymnast McKayla Maroney, Academy Award winner Jennifer Lawrence, Kirsten Dunst, Teresa Palmer, Mary Elizabeth Winstead, Kim Kardashian and Victoria Justice.
The perpetrator cracked the stars' icloud accounts to access hundreds of images before lying low as the furore raged.
He or she has now returned with the release of a fresh batch of photos - and Solo's image is the one causing the greatest uproar.
It is too revealing and explicit for Sportal to publish, but social media has gone crazy with word of the American goal-keeper's fully naked selfie.
@nicolettteeexo you look at a woman's stolen private pictures and make nasty comments about her body.you seem like a nice person....
— Pip (@pipperlue) September 21, 2014Some of the stars have confirmed the authenticity of the hacked photos while others are denying the pictures are genuine.
The hacker faces a lengthy prison sentence if found guilty of the crime but so far authorities have been unable to track he or she down.
