VB2014 paper: Methods of malware persistence on Mac OS X

Posted by   Virus Bulletin on   Oct 27, 2014

'KnockKnock' tool made available to the public.

Over the next few months, we will be sharing VB2014 conference papers as well as video recordings of the presentations. Today, we have added 'Methods of malware persistence on Mac OS X' by Synack researcher Patrick Wardle.

It has been a while since Apple used the scarcity of Mac viruses as part of its marketing strategy. Malware targeting OS X is fairly common these days, and it is likely to be here to stay.

In his presentation (which we previewed on our blog two months ago), Patrick Wardle showed various ways in which Mac malware manages to persist on a machine it has infected, thus making sure it runs even after a reboot. He also showed how many recent families of OS X malware maintained persistence.

Patrick also demonstrated the KnockKnock tool he has created - and made available for free. The tool, which can easily be extended using plug-ins, allows anyone to see persistent binaries that are to be executed automatically at each boot.

You can read Patrick's paper here in HTML-format, or download it here as a PDF (no registration or subscription required). You can download the presentation slides here. We have also uploaded the presentation to our YouTube channel.

Later this week, we will publish a new paper by Patrick in which he looks at a recently discovered OS X malware family.
