All the time we should be very cautious. Everything that comes from an unknown source should be treated dangerous no matter how inviting it may seem. Malwares and viruses are usually hidden from too-good-to-be-true offers but in the end, it will just lead you to opening your portals for harmful links.
Just recently, an organization lead by SophosLabs analyst Graham Cluley, discover a malware that has been hidden behind a new version of the famous Roovio mobile’s “Angry Birds” called “Angry Birds Space”.
The game has become the game of the tech world ever since it was introduced and some people might not be able to distinguish which one is a legit version.
Basically the game is not an official Google Play (formerly Android Market) game. It came from a third party source that Cluley refused to name.
“The Trojan horse, which Sophos detects as Andr/KongFu-L, appears to be a fully-functional version of the popular smartphone game, but uses the GingerBreak exploit to gain root access to the device, and install malicious code.” – This is what you get the time you would download the game from the unknown source.
Eventually the Trojan is connected to a remote website that would further install malwares into the infected Android smartphone.
