OS X Trojan horse redirects web browser.

Global Secure Systems (GSS) : 05 November, 2007  (Technical Article)
Global Secure Systems is warning Mac users of Trojan horse which requires software update to prevent vulnerability.
Leading IT security specialists Global Secure Systems (GSS) have warned Apple Mac users to revisit their IT security software and manually update it, following the arrival of the first serious Trojan Horse for the Apple Mac.

GSS' warning comes as Intego, an Austin, Texas-based Mac security firm, has reported the first serious Trojan to affect the Apple Mac platform.

'The Trojan is unusual in changing the computer's DNS server to new and malicious entry that actually intercepts and re-routes Web requests to malware-ridden and/or porn sites,' said David Hobson, managing director for GSS.

'The problem for Mac OS X 10.4 users is that the user interface does not allow the owner to see that the DNS server has changed. Even under OS X 10.5, the change(s) are not obvious, as the added DNS entries are dimmed and cannot therefore be directly changed,' he added.

According to Hobson, Apple Mac users should ensure they manually check and update their IT security software to the latest version from their IT security software vendor.

'They should also check with their software reseller that their products protect against this new and potentially serious malware development on the Apple Mac platform.
