Latest News Joanna Rutkowska writes: "At the beginning of this year, at Black Hat Federal Conference, I proposed a simple taxonomy that could be used to classify stealth malware according to how it interacts with the operating system. Since that time I have often referred to this classification as I think it is very useful in designing system integrity verification tools and talking about malware in general. Now I decided to explain this classification a bit more as well as extend it of a new type of malware - the type III malware."

Latest News There you are, happily playing around with an audio file you've spent all afternoon tweaking, and you're thinking, "Wow, doesn't it sound great? Lemme just move it over here." At that point your subconscious chimes in, "Um, you meant mv, not rm, right?" Oops. I feel your pain -- this happens to everyone. But there's a straightforward method to recover your lost file, and since it works on every standard Linux system, everyone ought to know how to do it. Briefly, a file as it appears somewhere on a Linux filesystem is actually just a link to an inode, which contains all of the file's properties, such as permissions and ownership, as well as the addresses of the data blocks where the file's content is stored on disk. When you rm a file, you're removing the link that points to its inode, but not the inode itself; other processes (such as your audio player) might still have it open. It's only after they're through and all links are removed that an inode and the data blocks it pointed to are made available for writing.

Latest News Something -- maybe a lot of things -- is wrong with how America conducts its elections. As you might have heard, there were a few problems down in Florida back in 2000, and more recently in the Maryland primary. No doubt, voting and vote-counting can be messy, complicated and subject to potentially outcome-shifting flaws. With that as backdrop and five days before Election Day, HBO weighs in tonight with "Hacking Democracy," a somewhat torpid documentary that is itself complicated, flawed and messy.
