Overview of the November 2008 Microsoft patches and their status.
|#||Affected||Contra Indications||Known Exploits||Microsoft rating||ISC rating(*)|
|MS08-068||The NTLM protocol allows an attacking server to reflect credentials and use them against the client gaining the rights of the logged on user.
Replaces MS06-030 and MS05-011.
UPDATE: Vulnerability first made public in March 2001, exploits readily available.
|MS08-069||Multiple vulnerabilities allow memory corruption (code execution with the rights of the logged on user), cross domain scripting and cross domain information leaks.
|XML core services
|KB 955218||CVE-2007-0099 was made public on January 4th, 2007.||Critical||Critical||Important|
We appreciate updates

- We use 4 levels:
- PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
- Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
- Important: Things where more testing and other measures can help.
- Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
- The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
- The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
- Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
- All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them.

Holger reported a site that via obfuscation and redirection pointed back to the same site as where Bojan initially found his malicious pdfs.
Interesting the pdfs are new files.
Checking the new pdf again (both file names have the same content (MD5: e51f24ec2e3d2cf71aa1ba74a7210841) on virustotal to get an up to date idea of the coverage, we get this:
All the rest of the products tested at virustotal fail to detect these newer pdfs at all at this time.
So, what are we to do ?
- Are your acrobat installations fully up to date on patches ? How can you be sure ?
Perhaps the policy file contributed by Elazar can help you:
Disclaimer: I've not tried this policy file.
Holger seems to have taken an interest in this and reported that they seem to have updated the attack once again, no more detection in virustotal.
A big part of getting this right is to be notified timely of such updates being available. Jacob reported that he noticed he didn't get the notification from Adobe for the last few updates. (You can sign up for it, but YMMV...)
An anonymous reader reported: "I observed the following on two different computers (one at work; one at home) about a week or two ago. Both mentioned that there was an update to Adobe Reader available but that the update failed. Subsequently, that message did not reappear. Manually selecting Update from within Adobe Reader allowed for the installation of the patched version, which required a reboot." Hence, take care when relying solely on automatic updates ...

The x-ed out stuff was spot-on, the spaces are added to the URL to prevent any reader from clicking on this. It was sent to an email address I actually have used in association with Google adwords, (although it's not that well targeted, I got other copies of it on addresses I use in conjunction with managing websites but not linked to adwords.)
Notice the lack of obvious errors aside of a date that's in the future (their timezone calculation might be off) and the concealed URL that does not point to google.com, but to .com68.ru
Now, when explaining to your users how to detect phishing from real warnings, do you think your users have a reasonable chance of noticing this before the credit card gets abused?
Tracing it back:
- com68.ru has a private registration. Sure, what's new.
- The email originated in 18.104.22.168/15 (used by an ISP based in Vladivostok).
- The actual DNS name didn't resolve at the time of this writing.
