We have disabled the site until a worm going around Twitter is blocked.A nasty worm is sweeping through Twitter this weekend. Up till now iTweet.net has been immune to the attacks, but a newer, trickier version was causing browsers to redirect to the spammer's website.
In response I've temporarily disabled the site while I work on a fix. Thank goodness I seem to have caught it within minutes of the new version spreading through the Twitterverse.
IMPORTANT: The worm was not able to spread via iTweet, nor was any data compromised (usernames and passwords are well-encrypted). The worm was exploiting actions specific only to twitter.com and causing people to automatically tweet deceptive links which caused itself to spread as others clicked those links. This didn't work with iTweet's different structure, it simply caused the page to redirect to their script where it stopped. I do recommend clearing your browser cache and cookies as a safety measure, and avoid using web-based Twitter clients until this worm is dealt with.
Please check back here on my blog for updates about iTweet, and check the Twitter status blog as well as their main blog for up-to-date information about the worm.
