Apple Macusers are no longer immune
toTrojan attacks, after a Texas-based
Mac security firm, reported the first serious Trojan to affect the
Apple Mac platform.
Users may be forced to contact their IT suppliers to protect
themselves.
The Trojan targets a computer's DNS server and adds a malicious
entry that intercepts and re-routes web requests to malware-ridden
and/or porn sites.
Preparing a defence against this malware will be difficult for
Mac users because their operating system does not allow users to
see that something is amiss. The user interface does not allow the
owner to see that the DNS server has changed, explained UK security
expert David Hobson, managing director for Global Secure Systems.
He advises users manually configure their systems against this
offensive code.
"Even with the latest versions of OS X, the changes are not
obvious, as the added DNS entries are dimmed and cannot therefore
be directly changed," he added. He also urged mac users to consult
their IT supplier to ensure their products are protected against
this potentially serious malware.
