Besides being a security Geek, I’m also an Internet marketer (no, not the bad kind—the good kind—I actually try to help people with what I sell). Twitter, at first blush, appears to be a great way to get your message out; it probably is, if done right, but it’s also easily abused. Yes,...

OMG! I just opened that box that Pandora gave me. I have often said that I don’t like password managers because I don’t consider them secure. That goes double for the password managers built into the browsers. I don’t like anything to reside directly on my system, so that leaves a remote...

A little Alliteration is good for writing effect every now and then; why not apply this to passwords? I don’t mean to write out an alliterative phrase and turn it into a password or passphrase (though you could, I guess); what I mean is to use a pattern that makes it easy for you to...

A botnet that uses Twitter for command and control? You bet. Jose Nazario over at Arbor Networks apparently found one: “Basically what it does is use the status messages to send out new links to contact, then these contain new commands or executables to download and run.” The bots connect to...
