Apple's new hit feature, the Siri personal assistant on the iPhone 4S is designed to be helpful and respond to users' voice commands; this even includes unauthorised users who may get hold of your iPhone while you are not looking, a leading security firm has warned.
Graham Cluley, a senior technology consultant at Sophos, wrote yesterday on his technology blog, "I borrowed a passcode-locked iPhone 4S from a colleague here at Sophos and, with his permission, was able to write an email, and sent a text message. If I had wanted to I could have meddled with his calendar appointments too."
Apparently locking down the iPhone doesn't help fixing this security loophole. Siri can still be activated with one tap. In order to be sure that Siri only listens to you, Cluley suggests a few steps: access your iPhone 4S settings, head to "Passcode Lock," and make sure Siri is set to "Off", that way "Siri cannot be used when the smartphone is locked with a passcode".
Despite a few minor setbacks, the iPhone 4S with its improvements has sold better than any iPhone before. The unprecedented 4 million units sold in the first weekend of availability could be just the beginning, Tim Cook said recently.
