"Smartphones running Google's Android software have been hijacked by an illegal botnet, according to a Microsoft researcher. Botnets are large illegal networks of infected machines - usually desktop or laptop computers - typically used to send out masses of spam email. Researcher Terry Zink said there was evidence of spam being sent from Yahoo mail servers by Android devices. Microsoft's own platform, Windows Phone, is a key competitor to Android. The Google platform has suffered from several high-profile issues with malware affected apps in recent months. The official store - Google Play - has had issues with fake apps, often pirated free versions of popular paid products like Angry Birds or Fruit Ninja. This latest discovery has been seen as a change of direction for attackers. "We've all heard the rumours," Mr Zink wrote in a blog post. "But this is the first time I have seen it - a spammer has control of a botnet that lives on Android devices. "These devices login to the user's Yahoo Mail account and send spam."

As is typical, the spam email looks to tempt people into buying products like prescription drugs. Security expert Graham Cluley, from anti-virus firm Sophos, said it was highly likely the attacks originated from Android devices, given all available information, but this could not be proven. This was the first time smartphones had been exploited in this way, he said. "We've seen it done experimentally to prove that it's possible by researchers, but not done by the bad guys," he told the BBC. "We are seeing a lot of activity from cybercriminals on the Android platform. "The best thing you can do right now is upgrade your operating system, if that's possible. "And before you install apps onto your device, look at the... more... - Winckel from Bookmarklet
