Recent Mac Malware

Paul Ducklin for Sophos/Naked Security: Digitally signed data-stealing malware targets Mac users in “undelivered courier item” attack This concerns the bot/RAT Sophos calls OSX/LaoShu-A.

Intego’s Arnaud Abbati tells us that a New OSX/Crisis Variant Invokes Pope Francis while Derek Erwin explains Why the Flashback Botnet is a Threat “with at least 22,000 infected machines.”

  1. I have contracted a virus on my MacPro that has bars on the screen during start up and then freezes the computer and scatters snow across the screen. I have tried removing it with sophos and ClamXav but it is still there. It allows me to access my desktop every 4 or 5 restarts.
    Any idea what it is and how I can get rid of it>
    Thanks

    • It doesn’t particularly sound like a virus: malware is usually designed to be inconspicuous, though it’s certainly not unknown for a malicious program to cause damage to an infected system unintentionally. I’m afraid I can’t offer any information on what the problem actually is: I can only recommend that you see whether a local repair shop can help.

      • Thanks for the comment. I guess I’ll have to take it in to be looked at.

  2. my Mac was doing the same thing when i started it up. It was running really slow and it kept freezing all the time on websites. I took it to the genius bar at the Apple store and all it was, was a matter of removing the malware. She did a check on the hard drive and it was all ok. I would suggest, Kimball that you take it toyour local Apple store. You can make a appointment online. Hope this helps
