RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission
From your blog: While we know there's still a lot of cleaning up to do in their binary planting closet, our research-oriented minds remain challenged to find new ways of exploiting these critical bugs and bypassing new and old countermeasures. In the end, it was our research that got the ball rolling and it would be a missed opportunity for everyone's security if we didn't leverage the current momentum and keep researching. I would change that around a bit. I would say our self-serving and marketing-oriented minds remain challenged to understand what security really is, but regardless, continue to find ways of trying to convince people this represents an actual security threat. In the end, it was our research that falsely created security concerns and confusion where time was better spent really doing just about anything else, but it would have been a missed opportunity to get our names in the media to sell our security services. t -Original Message- From: full-disclosure-boun...@lists.grok.org.uk [mailto:full-disclosure- boun...@lists.grok.org.uk] On Behalf Of ACROS Security Lists Sent: Thursday, September 15, 2011 3:05 AM To: bugtraq@securityfocus.com; full-disclos...@lists.grok.org.uk; c...@cert.org; si-c...@arnes.si Subject: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission Our new blog post describes some recent changes Microsoft introduced to fight against binary planting exploits.

Hi Thor, Thank you very much for sharing your point of view. If Microsoft thought the same though, they probably wouldn't be fixing these bugs. I suppose they don't understand what security really is the same way we don't. ;-) Regards, Mitja -Original Message- From: Thor (Hammer of God) [mailto:t...@hammerofgod.com] Sent: Thursday, September 15, 2011 6:11 PM To: secur...@acrossecurity.com; bugtraq@securityfocus.com; full-disclos...@lists.grok.org.uk; c...@cert.org; si-c...@arnes.si Subject: RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission From your blog: While we know there's still a lot of cleaning up to do in their binary planting closet, our research-oriented minds remain challenged to find new ways of exploiting these critical bugs and bypassing new and old countermeasures.

RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission
Hey Chris, I bet Microsoft actually like stating they just fixed yet another severe bug. Zero-day fixing is big business, you knoweven if zero is past a few days. I don't think Microsoft gains much from being able to say they fixed yet another bug - maybe if it were a bug they found internally and fixed proactively, but not like this. And I'm sure they'd rather be doing something else than fixing: fixing a product costs a lot, and it generates no revenue. Cheers, Mitja
RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission
I'm curious. Who is your contact at MSFT? Who is it that has told you they have a Binary Planting Clean-up Mission and where do they mention you as having anything to do with it? If you are going to claim MSFT's actions as substantive to your agenda, how about provide some details? t -Original Message- From: ACROS Security Lists [mailto:li...@acros.si] Sent: Thursday, September 15, 2011 1:41 PM To: 'Christian Sciberras' Cc: Thor (Hammer of God); full-disclos...@lists.grok.org.uk; bugtraq@securityfocus.com Subject: RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission Hey Chris, I bet Microsoft actually like stating they just fixed yet another severe bug.

RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission
Hi Thor, Microsoft is maintaining a list of binary planting bugs they've fixed here: http://technet.microsoft.com/en-us/security/advisory/2269637 You will find our name in some of these advisories. Calling the above effort a Binary Planting Clean-up Mission was merely a benign poetic exercise, and this is *not* an official name of any internal mission at Microsoft to the best of my knowledge.

RE: [Full-disclosure] Microsoft's Binary Planting Clean-Up Mission
Hi Adam, I'm afraid you don't fully understand the issue. This is not about placing your own DLL on a local machine so that a chosen application will load it (i.e., user attacking an application on his own computer). It is about an application running on your computer silently grabbing a malicious DLL from attacker-controlled location - possibly on a remote share - and executing its code (i.e., attacker with zero privileges on user's computer executing code on that computer). I hope this helps a little.

In addition, this looks like it could be ripe for abuse (if it is true): Even more interesting is the fact that you can specify a UNC path in the import section of the PE file. If we specify \\66.93.68.6\z as the name of the imported DLL, the Windows loader will try to download the DLL file from our web server. See http://www.phreedom.org/solar/code/tinype/.

That being, whether the user knowingly or unknowingly loads the malicious DLL - the application will be effected the same either way. To that point: it's been possible for over a decade (and perhaps even longer) so pretending that it's some brand new threat that needs to be dealt with immediately is foolish. possibly on a remote share - and executing its code (i.e., attacker with zero privileges on user's computer executing code on that computer). Zero privileges? So having write access to a share that the user accesses/loads files from - what do you call that? This is a social engineering attack - absolutely nothing more. On a related note: have you also contacted Linus about LD_PRELOAD?
