If you have a Mac, you already know that any application installed in your Mac requires authentication as an administrator before running the operation, and the same is true for malware. This kind of applications need administrator access and for this it is necessary that users enter the Mac password when installing the infected application. Well, everything you knew until now no longer applies because a new version of a Trojan can infect a Mac without a password. OSX/Flashback.K is the name of the version that is now circulating on the Internet, and it uses a vulnerability in Java SE6 to infect the Mac and download certain files from the hackers' servers, files that help them take control of Safari and redirect your traffic to a certain website.
When infected, the Trojan asks you to enter the administrator password, but it infects the Mac even without it, although entering the password changes the method of infection. Although Microsoft released an update that protects users of the Windows operating system, Apple did not do this for OS X and those from F-Secure recommend disabling Java until the problem is solved by the Apple company. Practically anyone can be infected by this Trojan at any time regardless of whether they authenticate the installation of the infected file. Those from F-Secure details here instructions for disinfection and if Safari on Mac opens pages you don't recognize by itself, then it would be good to follow the steps.
