About 57% of infected machines were in the US, 20% in Canada, 13% in UK and 6% in Australia. Apple has already issued patches that curb the vulnerability, but it does not necessarily mean that all users have applied the security patch on their Macs. Even Mozilla has block listed all the older and vulnerable Java plug-in from Firefox. Users are recommended to install the recent Apple Java update to close the hole which allows malicious web pages to drop the trojan onto a system and to always check which application is actually asking for your password when requested.
Update: To detect if a system is infected with Flashback, run each of the following commands in the Mac OS X Terminal:-
defaults read ~/.MacOSX/environment DYLD_INSERT_LIBRARIES
defaults read /Applications/Safari.app/Contents/Info LSEnvironment
defaults read /Applications/Firefox.app/Contents/Info LSEnvironment
If all these commands respond with "The domain/default pair of ... does not exist", then there is no Flashback infection. Otherwise consult the F-Secure advisory for manual removal instructions.
