OSX/HellRTS – more info

I’ve been asked for more information on the recent threat that ESET calls OSX/HellRTS.AA. ESET hasn’t put up a description so far, but several other vendors have:

And while I’ve already pointed to descriptions by Intego and Sophos in a previous blog, they are, for completeness, at:

http://www.sophos.com/security/analyses/viruses-and-spyware/osxpinheadb.html 

If you were wondering, the reason that this detection has so many variant names is that nowadays, variant naming tends to reflect the type of detection used in a product rather than the identity of a single binary: otherwise, we’d be seeing malware with names like W32/YetAnotherNastyTrojan.HNEDODENOXQIDSEZZUAUOP… 😉

I’ve written a couple of papers on naming issues: see http://www.eset.com/resources/white-papers/Harley-Bureau-VB2008.pdf (written with Pierre-Marc Bureau) and http://www.eset.com/resources/white-papers/cfet2009naming.pdf.
