Macintosh Security Company Intego, the developers of VirusBarrier have released a report on Mac and iPhone security for 2009.

The report focuses on various Trojan horse attacks, malware found in Torrent application downloads, attacks on jailbroken iPhones, Mac OS X vulnerabilities and third party vulnerabilities.

The following excerpt is taken from the report: -

Many of these operating system vulnerabilities pave the way for unseen malware attacks. Some of them are such that merely visiting a booby-trapped web page can compromise a Mac. This underscores the importance of security software that protects not only from malware but also from web threats and the many other kinds of menaces that target Macs. It also highlights the need to keep software up-to-date. Both for Mac OS X and for third-party software, users should make sure that they have the latest versions of their software, since some programs—such as Adobe Reader, commonly used to view PDF files—are easy to attack with known exploits circulating in the wild.
