Zunker is not alone
Orlando Padilla | 16 Jul 2007 | 0 comments

Earlier this year, I saw some screenshots of the Zunker bot and itscontrolling interface. I became curious about the existence of othersimilar interfaces and began paying a bit more attention to the spamcoming into my inbox on a personal account. After a few weeks ofwandering through IP blocks referenced by the spam, I ran across anopen directory containing a few screen shots of what looked likeanother interface actively spamming multiple products.

The following screen shot shows a statistics screen for a botnetthey are currently using. Similar to the Zunker interface, thisinterface also has the ability to group by country. It looks like thefeature is broken though, as you can only see one bot, which isoriginating from Poland. Given that, it is tempting to presume theowner is Polish; however, the interface's text is entirely in Englishand the screen shot was found on a Russian server. It could, however,mean that the person leasing this interface is controlling it from...

The Impact of Malicious Code on Windows Vista
Orlando Padilla | 02 Mar 2007 | 0 comments

he media surrounding the effectiveness of Windows Vista's new security features has (in my opinion) just begun. Microsoft's reach is well beyond that of any other software vendor in the world, and with this achievement comes fame, power, and a corporate life under a microscope. To honor this tradition, I previously posted an entry about the effects of malicious code executed under a default Vista environment; if you haven't read it, you are certainly encouraged to. This research has now been completed and this new entry should serve as a compliment to my previous post. A paper detailing the full research has been made available here.

The outcome of the research:

In my previous blog, I mentioned that...

Hit or Miss? Vista and Current Threat Survivability
Orlando Padilla | 01 Dec 2006 | 0 comments

The long anticipated Windows Vista operating system is finally out the door and as anyone would agree, it’s celebration time at Microsoft. But, let’s discuss what we are in for with a peek at the default user environment on the 32-bit platform.

Symantec Advanced Threat Research decided to conduct an analysis of Windows Vista’s security enhancements provided by the user account control (UAC) and resulting new security barriers. No formal requirements were defined, although a few guidelines were set to stay organized; gather a sample set of malicious code, execute them under the default UAC environment, and carefully determine their success. The results were then broken down into three categories:
1) Successful execution of malicious code
2) System restart survivability
3) Failed execution of malicious code, and why

There are two important prerequisites in place to establish fair play practices:
1) All malicious code must be...
