Reuters: At the Black Hat security conference, researcher Charlie Miller from Accuvant demonstrated an attack that exploits Android smartphones' near-field communications (NFC) capabilities. Miller made a device the size of a postage stamp that could be placed anywhere people are likely to walk by. When they do, any Android phones they are carrying would be infected by malware.
Several other researchers demonstrated other methods for successfully hacking Android phones. "Hopefully Google can solve the problem[s] quickly," said Nicholas Percoco from Trustwave's SpiderLabs. "For now, Android is the Wild West."
