Bad news for Android today as a new report from Microsoft researcher, Terry Zink, says that an undisclosed number of Android smartphones have been used as illegal botnets. Botnets are nothing new to PC users as they’ve had problems with machines getting infected and sending out masses of spam mail, like the message above, to others. They’ve now arrived on Android apparently as Zink noticed that some spam e-mails were coming with the signature, “Sent from Yahoo! Mail on Android.”
Most of these were probably acquired by someone downloading an app off of the internet instead of a certified app store such as the Google Play Store or Amazon Appstore. Some could also have come from a rogue Yahoo! mail app. We also have a list of the countries that they’re coming from and they are Chile, Indonesia, Lebanon, Oman, Philippines, Russia, Saudi Arabia, Thailand, Ukraine, and Venezuela.
To help prevent anything like this from happening to you, you should always read app reviews and descriptions before installing, download apps from a certified app store, and keep some sort of antivirus software on your phone such as Lookout, Norton, or AVG. Remember to always be careful with downloading things from the internet.
