Sony only released PlayStation Home a few days ago but the online virtual world has already been hacked multiple times over the weekend. Particularly, one user managed to circumvent some of the advertising systems built into Home by using Apache and DNS redirection to display his own images and videos - though only locally.
Granted, this can hardly be considered a major security threat but another, more worrisome vulnerability will supposedly enable gamers to upload, download or delete any file from the Home server. While the claims have yet to be verified, if true it would be a potentially disastrous oversight on Sony's part, even if PlayStation Home is still in beta.
