Linux Tsunami hits OS X

We’ve just come across an IRC controlled backdoor that enables the infected machine to become a bot for Distributed Denial of Service attacks. The interesting part about it is that it’s a Mach-O binary – targeting Mac OS X. ESET’s research team compared this to samples in our malware collection and discovered that this code

PDF Trojan Appears on Mac OS X

  A new trojan has been released targeting the Macintosh Chinese-language user community.  The trojan appears to the user to be a PDF containing a Chinese language article on the long-running dispute over whether Japan or China owns the Diaoyu Islands.   When the user opens the “PDF” file, it attempts to mask the installation

MacDefender: The sky is not falling…

In the last few days, I have been asked by a journalist (or four) what MacDefender means for the future of Apple security, and if I thought there was excess hype around it.   I'll address the second question first.   I think its safe to say the current malware would not be newsworthy if

Social engineers don’t care about your OS: and nor should you

Security companies in general and, unfortunately, anti-malware companies in particular, are often accused of ‘hyping’ threats because of a perceived self-interest.

The recent MacDefender Trojan has been receiving “rebranding” facelifts since it came out.

Mac Malware (again)

An interesting comment was made to my last blog on Snow Leopard, Mac malware and all that. I’ve approved the comment, but since people who read the blog earlier won’t necessarily go back to see what comments it’s attracted, I’ll answer it here, at more length. Mac User said that "Currently, the only way to get

Mad Macs: Beyond Blunderdome

I really ought to be working towards some really urgent deadlines, but I can’t resist a quick comment on the antimalware detection feature in Snow Leopard – darn, I’m going to have to upgrade to get a proper look at it – since several AV people, including our own Aryeh Goretsky have commented. I have
