can joe barr's opinion of the malware industry be trusted?

well, joe barr is at it again... i've blogged about joe once before and where the previous article i wrote about seemed to just be a case of false authority syndrome, this new one about whether the anti-malware industry can be trusted seems to be a more deliberate smear campaign...

when he's not throwing out non-sequiturs like what happened to dan greer formerly of @stake (which isn't really part of the anti-malware industry), he's redressing other non-sequiturs to look like they're actually relevant... for example:
US-Cert knows about the problem of the super-inflated malware numbers in their summary,
except that cert doesn't count malware, they count vulnerabilities - ergo what cert is or isn't doing, what they do or don't know has no bearing on whether the anti-malware industry can be trusted...

then there's innuendo about timing things specifically to make OSX look bad:
The SANS Institute, -- a name which sounds all officious and possibly not profit oriented, but which is owned by the mysterious but definitely for-profit Escal Institute of Technology -- recently did an unusual update to its Top 20 list of vulnerabilities.

They issued their "update" in order to trumpet the assertion that Apple OS X is now just as exposed and vulnerable to malware as Windows. The timing of the release of this unusual "update" is suspicious, coming as it did on the eve of the new advertising campaign by Apple which plays up the fact that Apple is pretty much immune to the types of malware infestations that plague Windows. Previous updates to this list have usually come in the fall: November, 2005; October, 2004; October, 2003; and October, 2002.
what mr.barr fails to acknowledge, however, is that there's a 3rd event in this coincidence - that being the dramatic change in the security landscape of OSX around the same time... 2 viruses and a spate serious vulnerabilities - issuing a report to inform people of the new state of things was a responsible thing for SANS to do...

there's some crazy re-interpreting of that same report, too:
The SANS Institute announcement seemed to be designed to destroy -- or at least bring into question -- the idea that Apple OS X is more secure than Windows. In a document sent to members of the press prior to the teleconference, the SANS Institute wrote:

During the past few months, Apple Safari browser users faced their first zero-day attack. A zero-day attack is one that causes damage to users even before the vendor makes a patch available. In this case, Safari users who just browsed a malicious web site found their computers automatically downloading and executing a malicious file. The user made no error other than to visit the web site. Apple patched Safari to fix this flaw, but almost immediately had to issue a second patch to stop another attack involving email attachments. The experts involved in the 2006 Top 20 Spring update agree that OS/X still remains safer than Windows; but its reputation for offering a bullet-proof alternative to Windows is in tatters. As attackers are increasingly turning their attention to the platform, OS/X vulnerabilities are being discovered at a rapid pace, which could erode this safety in the future.
now, how exactly can the report destroy or bring into question the idea that OSX is more secure than windows when his own quote of the report explicitly says that OSX is still safer than windows? and his later jab (by way of quoting a 3rd party) at the supposed claim that OSX's security reputation is in tatters? the quote clearly shows that the report said OSX's reputation for being bullet-proof was in tatters - which it is... it can't be considered bullet-proof anymore, it's been proven that it's not totally immune to threats...

the real meat of the article doesn't come until the section entitled "From Russia with malice", however... joe barr clearly has a venomous contempt for kaspersky labs, he goes on and on about supposed wrong-doings, such as:
Kaspersky Lab, a Russian Internet security company which operates around the globe, including here in the USA, has been spreading FUD about malware targeting Linux for years. I've cited this example from 2001 before, but here it is again, and it still appears on their Web site. Hey, maybe the SANS Institute used it as a template for their anti-Apple effort. I quote:

Predictions regarding a world epidemic of Linux-viruses have come true in the first quarter of 2001. The latest incidents caused by the Ramen Internet-worm and its numerous modifications, as well as the multi-platform virus Pelf (Lindose) and other Linux-targeted malicious code, have proved that this operating system, (previously considered as the most protected software), has fallen victim to computer viruses.
while one would probably not consider ramen going into the wild to be comparable with the windows worm epidemics like blaster or sasser, compared with other linux malware it was a very big deal... as for pelf, cross-platform infectors have long been considered the means by which self-replicating linux malware would become really widespread and pelf was an indication that such infectors were coming...

of course, since he was chronicling all the perceived misdeeds of kaspersky he had to include 'the case of the non-viral virus' that i de-debunked previously, but then he goes on to describe his disbelief over their linux malware report that showed there were 91 viruses for the linux platform:
I asked Kaspersky Lab if they had any documentation to back up that claim. Jennifer Jewett, a public relations person representing Kaspersky, told me "the documentation sighting the viruses is included in the Encyclopedia on Kaspersky's Viruslist site: http://www.viruslist.com/en/viruses/encyclopedia."

I searched the encyclopedia for Linux viruses and came up with an astounding 972 hits. But just the barest hint of an analysis of those hits reveal that the number would break an industrial-strength bogusity-meter.
strangely, when i did a search for linux viruses on that site, i got 92 hits not 972... just one more than was indicated in the report - most without actual descriptions but at least they include the aliases that other products use so that one can corroborate their existence... is he incapable of using a search engine or just so biased against kaspersky that he can't manage due dilligence? he knew the result set shouldn't have been anywhere near that big, he should have refined his search to narrow it down to just viruses (972 would have been the list of all linux malware, not just viruses, though the number now stands at 976 and will probably change again as time wears on)...

his final bit of evidence against kaspersky came from the recently noted intended macro virus which caused the confusion i wrote about earlier:
After this story was submitted, and the week following another black-eye for Microsoft security in the form of malevolent macros in MS Word, Kaspersky Lab issued another headline-grabbing but bogus alert for a proof-of-concept of the same type of attack on MS Word's largest competitor, OpenOffice.org. Was the timing once more just a coincidence? I don't think so.
since the existence of the malware was independently confirmed and since kaspersky labs didn't create it themselves, the timing was entirely out of their hands... it gets discovered when it gets discovered... should they have kept the first openoffice malware a secret? would it have really served the public to sit on the fact that openoffice is now being targeted by at least one malware writer? somehow that doesn't seem likely...

joe barr concludes that the anti-malware industry cannot be trusted and he attributes all these misdeeds to a desire for more money - so what should we attribute joe barr's misdeeds (ie. his FUD) to?

the case of the non-expert expert: a rebuttal to "the case of the non-viral virus"

how many people read the newsforge article titled "the case of the non-viral virus" by joe barr? if you did then you've just witnessed false authority syndrome in action...

let's deconstruct it, shall we?

Thus, once and for all, there is an end to the notion that Linux is somehow immune to the viral infections that plague the Windows world.
it is not the first linux virus, not by a long shot... linux viruses have been around for years now and it's really quite absurd that anyone would still be holding on to the notion that linux is immune...

One minor thing is that the alleged virus -- called Virus.Linux.Bi.a -- being trumpeted far and wide by Kaspersky Lab is not really a virus, but rather "proof of concept" code, designed to show that such a virus could be written.
there is nothing that says something cannot be both a virus and a proof of concept... the fact is that the first virus for any platform is a proof of concept by default... the first virus that performs function X is a proof of concept... it's amazing that someone could pass themselves off as an authority on a subject and be so clueless about the terminology...

for the record - Virus.Linux.Bi.a IS a real virus...

A second caveat is that for it to work on Linux, a user has to download the program and then execute it, and even then, it can only "infect" files in the same directory the program is in.
the same limitations are true for quite a few DOS and windows viruses... these limitations do not stop it from being a virus...

Exactly how the program gets write permissions even in that directory is not explained.
unless linux has changed considerably since i last used it, individual programs do not require their own permissions... some special cases have special user accounts created just for running them, but by far most programs do not... even so, it is never the program that has permissions, but rather it is the user (whether the user is a real person or not), and in this case the viral program runs in the context of (and has the permissions of) the user who executes it...

And finally, it's not a virus at all. It can't replicate itself, which is one thing that makes a piece of malware a virus.
the author seems to be talking out of his ass here... while it's true that self-replication is a requirement, the program in question DOES self-replicate... it creates copies of itself that it inserts into other programs - i'm not sure what the author of that article thinks self-replication is but making copies of itself is the very definition of self-replication...

for completeness sake, here is the original weblog entry from the kaspersky folks about this cross-platform virus: http://www.viruslist.com/en/weblog?weblogid=183651915
you can plainly see from the description that the program in question both self-replicates and infects other programs - a virus by any reasonable definition and even by the wikipedia one the author chose to cite...
