Adobe util.printd Zero Day

A critical vulnerability was discovered early this week in Adobe Reader and Acrobat versions 9.2 and earlier which could allow attackers to gain control of the affected system, not even a week after Adobe released a critical update for its Flash Player on patch Tuesday last week. The attack uses a weakness in a function called util.printd along with a heap spray implemented with Javascript to attempt to inject shell code.

Forensics: Beverages Aside, A Look at Incident Response Tools

In November, Microsoft’s forensics tool called COFEE (Computer Online Forensic Evidence Extractor) was leaked on torrents for download. The news coverage was much hype about nothing, as many free tools already out there exceed COFEE in features and functionality.

Regular or Decaf? Tool launched to combat COFEE

About a month ago, there was much news about the release of COFEE into the torrent wild. I even gave my two cents about the much hyped forensics toolkit which is provided to law enforcement for the purposes of easily capturing volatile data from personal computers during evidence collection. A tool to counter COFEE, aptly [...]

From Promiscuous to Port Scanning with Powershell

It’s been a while since my last post regarding Powershell which showed how to scan hosts for network interfaces in promiscuous mode. This time around, we’ll scan for some well known ports in our Active Directory to see who has a local IIS or SQL Express running on their machine. I know what you’re thinking. [...]

Remote SMB Exploit: Crashing Windows 7 and Server 2008

Python code was posted today by Laurent Gaffie on his blog, demonstrating a much too easy way to remotely crash a Windows 7 or Windows Server 2008 machine. The crash is caused by sending a NetBIOS header which specifies that the SMB packet is 4 bytes smaller or larger than it actually is. In this code sample below, you can see that the header has the length of the packet set to 9a rather than 9e (4 bytes smaller).

More COFEE Please, on Second Thought…

The forensics tool provided to law enforcement officials created by Microsoft called COFEE  (Computer Online Forensic Evidence Extractor) has been leaked on torrents last week, and this has caused quite a bit of excitement.  Let’s see if the big deal is warranted.

Where is your BES Policy?

Several months ago, users of a wireless carrier in the United Arab Emirates (UAE) were sent an SMS message to their Blackberry devices instructing them to install a software patch that would resolve recent network trouble they’ve been experiencing. The patch turned out to be spyware (Etisalat.A[MA]) and would intercept the user’s email, sending the [...]

Adobe to release critical update on patch Tuesday

A new zero-day vulnerability in Adobe Reader and Acrobat 9.1.3 has been identified by Chia-Ching Fang and the Taiwanese Information and Communication Security Technology Service Center that allows an attacker to remotely execute arbitrary code. The attack is seeded by providing via e-mail or download a specially crafted PDF file which in current examples will then drop a malware executable as well as an unaffected pdf file.

This article takes a look back at the different functional levels of the past and what is new in the latest release of the server operating system for Active Directory (yes, a recycle bin for AD objects!).
