SANS has a blog post relating an anecdote about malicious links on a Facebook wall. The author said “As for Bitly – I would use extreme caution with any links identified as source bitlyDOTcom.” I laughed because the SANS handlers are typically against links. They want you to browse with Firefox and NoScript. Always use a bookmark that you have verified, and you might just want to SHA1 the bookmark to make sure no one has tampered with it. I’m only exaggerating slightly. I only mention that as background information.
What was funny in this case is the ShareThis plugin at isc.sans.edu uses bit.ly when you use their button to compose a tweet. Even better than this, @sans_isc tweeted a link to this post using, guess what, bit.ly. (Twitter does provide the real URL when you mouse over the link, but I still find it funny.
Big fan of Firefox and using NoScript here. Never said I wasn’t paranoid. 😉
