According to F-Secure, remote command-and-control (C & C) are used to connect with infected machines is the installation of Apache. Malware embedded in the PDF is new malware for the Mac.
"The appeal of the PDF is a good trick to get people to install trojans," said Sophos senior security adviser Chet Wisniewski. "The program works when you open a document, and then install malware without your knowing it."
Furthermore, Wisniewski said that, Windows is still preferred targets of cyber criminals because there are more machines to attack.
