   Cross-platform malware is still a rare occurrence, so when it's detected, it   
   usually attracts more attention than the malware engineered to affect only one   
   particular platform.   
      
   A recent one, detected by McAfee and "named" IncognitoRAT attacks   
   both Windows and Mac OS users. So, how does it manage to do it?   
      
   "IncognitoRAT is one example of a Java-based Trojan discovered in   
   the wild that is being downloaded and installed by another component. This   
   malware behaves like other Windows botnets but uses source code and libraries   
   that can operate on other platforms," explains McAfee's Carlos Castillo.
