Aza Raskin's Tabnapping is a proof-of-concept for a fiendish attack: a tab that waits until you're not watching, then turns itself into a convincing Google login screen that you assume you must have opened.
Actually, it's even sneakier: it can use CSS-based analysis to figure out which websites you login to, and then can use cross-site scripting to reload a different tab -- another one that you're not looking at -- to turn itself into a convincing login screen.
Every time you include a third-party script on your page, or a Flash widget, you leave yourself wide open for an evil doer to use your website as a staging ground for this kind of attack. If you are the evil doer, you can have this behavior only occur once in a while, and only if the user uses a targeted service. In other words, it could be hard to detect.
You can also use a cross-site scripting vulnerabilities to force the attack to be performed by other websites. And for browsers that do not support changing the favicon, you can use a location.assign call to navigate the page to a controlled domain with the correct favicon. As long as the user wasn’t looking at the tab when the refresh occurred (which they won’t be), they’ll have no idea what hit them. Combine this with look-alike Unicode domain names and even the most savvy user will have trouble detecting anything is amiss.

Investigative tech journalist Joseph Menn's (previously) next book is a history of the Cult of the Dead Cow (previously) the legendary hacker/prankster group that is considered to be "America's oldest hacking group."
Using software-defined radios, researchers from Trend Micro were able to reverse-engineer the commands used to control massive industrial machines, including cranes, excavators and scrapers; most of these commands were unencrypted, but even the encrypted systems were vulnerable to "replay attacks" that allowed the researchers to bypass the encryption.
"Letterlocking" is a term coined by MIT Libraries conservator Jana Dambrogio after she discovered a trove of letters while spelunking in the conservation lab of the Vatican Secret Archives; the letters had been ingeniously folded and sealed so that they couldn't be opened and re-closed without revealing that they had been read. Some even contained […]
