Win7/IE8 Exploit - CanSecWest - Vancouver BC, Canada

Recent trends for malware usually point to some older version of Internet Explorer running on Windows XP.  The lack of address randomization and execution protection makes it an easy target to create functioning exploits.  This years CanSecWest security conference again proves that it draws some of the brightest security researchers from around the globe.

As usual Charlie Miller is there on his "no more free bugs" tour - pointing out that Apple still hasn't taken security seriously enough, and showing through 5 lines of python code ways to reliably identify 20+ exploitable bugs in very common Internet related applications.  Seriously Apple, time to implement the basics, users of your operating system are not just educated coders and security people, they are common people that like to click through stuff.

More interesting though is the exploit of a fully patched IE8/Windows7 platform by Peter Vreugdenhil.  His two step bug and exploit avoids both the ASLR, and permanent DEP protections which have made this target so difficult to exploit, proving that if it is built by humans it can be unbuilt by humans.  Paper here.

Rounding out the conference so far is French researchers presenting on abuses of computing capability within host based network cards.  Did you realize that your network card is really an always-on always-listening mini-computer which can be used to listen into communications and access host-memory directly?

More to come from the conference over the next couple days...

Local Classified Penny Auction Scam

While there are a lot of new posts regarding the new ways to exploit people using novel techniques and 0day exploits, there continues to be a rash of tried and true methods of coercion.  I want to just walk through a simple example and reflect on how effective these methods continue to be. Many people turn toward online classified sites to buy and sell items online.  This example starts with kijiji.ca which even I've used on occasion to find used electronics and other items.  Doing a search on the site for a " Samsung Galaxy Note 2 " returns a posting from today with someone selling one for an unreasonably priced unit. $125 for a $500 phone?, but what if it's for real?  No harm in just asking some simple questions.  Email sent with some obvious questions regarding the condition and location. About an hour passes before I get a response from what appears to be a legit seller. Notice no answer to the questions I asked, but a friendly pointer at where th

OpenSolaris, ZFS, iSCSI and OSX - Creative Storage - Part II

In part I of this post, I looked at the simple steps required to setup a relatively simple storage solution using OpenSolaris, ZFS, iSCSI and OSX. This was about a month ago, and I've made some significant changes on how this is used for me. At the end of the last post I left off on the part dealing with configuration of the iSCSI initiator side of the solution. I stopped here because there were some issues related to the installation and use of the software. The iSCSI initiator that I was using was Studio Network Solutions GlobalSAN initiator (version 3.3.0.43) which is used to allow for connections to their products. This software will also allow for connections to ANY iSCSI target! After the configuration of the iSCSI target on the ZFS pool, and installation of the client it was trivial to get the connection established with the storage pool, and it showed up in OSX as a raw disk which had not been formatted. I proceeded to format the disk as HFS+ and it then mounted as a lo

Edmonton HeartBleed Information Session - April 16th, Royal Glenora Club

Since the latest major OpenSSL vulnerability was publicly disclosed, many people and organizations are scrambling to understand, respond and prepare themselves for the future.  Twitter, vendor support channels and media outlets have been quick to cover different angles of the issue but there has been overwhelming amount  of information released. With all this information, it can be difficult to understand what's relevant.  To help clarify we holding a special ISACA sponsored 2-hour session on Wednesday, April 16th, starting at 12:00pm at the Royal Glenora Club.   Benoit and I will be attempting to explain as much of the issue as we can from a technical and non-technical perspective, discussing the vulnerability, its scope with relation to our personal and professional lives and other related concerns such as our trust in the public PKI system.  The second hour we will be an interactive discussion about how others are dealing with problem, questions about related topics,
