Sony suffered its third cyber attack in two months as the Sony Music Brazil website was shut down due to a series of security breaches. The company's Brazilian online music service was the target of an attack on Saturday which left the website down and defaced with a page titled "Hacked The UnderTaker" (seen above) signaling that it had been compromised. This doesn't seem to be the work of LulzSec, the hacker group responsible for last week's Sony server break-in. The site has since been taken offline. Sony Music Brazil is investigating the attack and is not sure if any private data was exposed.
