    Yep. I read that.
    There was a recent update from Apple for Java.
    But how would one if their machine had already been compromised?

    Good question. What can one use to scan for something like this? Is this a good reason to install AV software? I don't have any at the moment.

    Install the update.
    The article has a link to an f-secure article that tells you how to fix it.

    And yes, this isn't a self replicating virus but it is pretty hairy malware.
    Safe browsing practices help.
    Using Opendns or dyndns internet guide can help too. They will warn of potentially bad sites.

    Run through the commands from the F-secure article and you will be fine. Update the system as suggested and this will be fine. I havent checked my MBP yet, but I have my MacMini and it was a breeze. Of course, it wasnt infected (I dont browse the internet on that machine) as it is only a media server. I will be checking my MBP when I get home.

    I understand that, to be infected, you would first have to approved a phished certificate saying that it was from Apple.

    So once again the user is the final guardian.

    True?

    yep... laziness is what both the virus authors and virus-scanners rely on. If people paid attention to what they were doing, neither would have much luck in accomplishing their goals.

    'Rude awakening' for Mac users as cyber attack infects 550,000 of Apple's 'virus free' machines - with UK and U.S. worst hit
    April 5, 2012
    Print Version
    Source: Daily Mail

    A new computer trojan has infected 550,000 machines running Apple's Mac OS X - and many could still be vulnerable. The infected machines are now part of a 'botnet' of zombie machines which can be controlled by cyber criminals and 'told' to download new malicious software.

    The attack has been described as a 'rude awakening' for Mac users.





    The attack has afflicted machines in America and the UK worst, according to Russian security vendor Dr Web's statistics

    The new attack was spotted by Russian anti-virus vendor Dr Web.

    'We conducted research to determine the scale of spreading of Trojan BackDoor.Flashback that infects computers running Mac OS X,' says the Russian antivirus vendor.


    'The botnet encompasses more than 550 000 infected machines, most of which are located in the United States and Canada.



    Can we develop more info on this here?

    So.

    "Don't click on strange and questionable stuff".

    Then the OP really has nothing to worry about, which was his question.

    See other thread.

    Don't click on and authorize weird stuff and you'll be fine.

    It only gets in if the user opens the door and invites it to enter.

    You know, like a vampire cannot enter your house unless you specifically invite it in.

    As in entering your admin password or accepting a phished security certificate.

    Just say no.

    It's a zero-day attack patch that applies to Oracle Java. It only applies to Snow Leopard and some but not all Lion . Apple has recenlyt quit bundeling Oracle Java with Lion.
