Tracy Kitten at BankInfo has an interesting article about the Ramnit worm which is worthy of a read (even I would say by the general public). Ramnit is particularly pernicious because: Ramnit’s man-in-the-middle looks like an actual social-media or bank-account sign-in page that captures a user’s ID and password, and sometimes other personal information en . . . → Read More: BankInfo Ramnit Article In theory if the world were filled we universally good people, “bitly” and “TinyURL.com“, which given long URLs provide short ones, are a great idea. However whenever I get one I find that I’m frankly terrified to click on them. Why?

That a deadly virus would escape from the military possibly causing zombies: http://www.cnn.com/2010/TECH/web/11/17/stuxnet.virus He was just wrong that humans would be the target. Well, researchers have devised a way around most modern anti-virus software. Yet another example of, “With friends like these, who needs enemies.” Again, I know “security by obscurity” is false security, but it’s not like the bad guys need as much help as they’re getting! Completely different from Cisco IOS, so hard to remember: Log into the PIX/FWSM and go to “enable” mode. Do a “who”:
Choose the IP of the session you want to kill and grab the number. In this case I want to kill the “192.168.100.5” session, so I want “2”. Then kill it:
