With the increased attacks to gain control of Twitter accounts.
There are a few things that may help while we wait for Twitter to get a handle on security.
There are a number of link scanners that can be used to fight rogue links within Twitter. These are the two that I know about.
If you do not trust or have the link scanner software, do not click on suspicious links within Twitter. If your unsure don’t click.
There is a firefox plugin called LongURL Mobile Expander. In it’s own words:
You should always know where a link takes you before clicking on it. Services like TinyURL.com make that difficult. LongURL Mobile Expander uses the LongURL.org web services to let you know where shortened links *really* go. This can be found at https://addons.mozilla.org/en-US/firefox/addon/8636
The other thing I would suggest people do is go through their account connections http://twitter.com/account/connections and remove connections that are no longer required.
Change your password regularly.
These are things that may help while we wait for Twitter to concentrate on stability and security. We all like shiny shiny like lists and update notifications, but stability and security for me first please.
