On Tuesday, McAfee Avert Labs discovered W32/Realor.worm in the wild that was actively modifying all Real Media (*.rmvb) files in its path. These “infected” media files launch a malicious webpage without prompting, as they are being viewed by the user in Real media player. These files can be music or videos hosted on a network drive containing corporate presentations, a personal media server, or a P2P shared folder et cetera. When was the last time you hesitated in opening a movie file ?
