UPDATE: See Intego’s full security memo<\/a> with detailed information about the MAC Defender fake antivirus.<\/p>\n

Intego has discovered a rogue anti-malware program called MACDefender, which attacks Macs via SEO poisoning attacks. When a user clicks on a link after performing a search on a search engine such as Google, this takes them to a web site whose page contains JavaScript that automatically downloads a file. In this case, the file downloaded is a compressed ZIP archive, which, if a specific option in a web browser is checked (Open “safe” files after downloading in Safari, for example), will open. The file is decompressed, and the installer it contains launches presenting a user with the following screen:<\/p>\n

\"\"<\/p>\n

If the user continues through the installation process, and enters an administrator’s password, the software will be installed.<\/p>\n

\"\"<\/p>\n

It is important that users not continue with any unexpected installation of this type. Intego VirusBarrier X6’s<\/a> malware definitions will be updated today, and Intego will be publishing a security memo when we have more information about this malware. For now, the threat is low, but users should be careful not to install software when installers open unexpectedly.<\/p>\n
