Intego, a Mac security software company, has reported a new Mac Trojan, known as OSX/Leverage.A., that creates a backdoor on an affected user’s machine.
 
The Trojan is an application that is disguised as a picture; the .app file-extension is not visible by default. The Trojan application installs a permanent backdoor that allows the attacker to send a variety of commands. You can read more about the OSX/Leverage.A. Trojan at .http://tinyurl.com/k87rw6k .
