Explainer: How Tweetdeck made a balls of things in 12 easy steps

It wasn’t hacked. And you don’t need to change your password.

YESTERDAY TWEETDECK WAS shut down for a time after a major security flaw was discovered.

Users of  the Twitter client (which is owned by Twitter) began seeing random pop up windows and retweets on their accounts, and a shout went out across the internet:

hacked

Wrong!

Tweetdeck wasn’t hacked. It just made a balls of things. Here’s how…

1. A guy in Austria decided to tweet a cute little emoticon

A heart emoticon to be precise.

His name is @Firoxl and he successfully tweeted the heart using HTML code.

2. So what’s the big deal?

@Firoxl had exposed a flaw in the system. He had discovered that using code, anyone could insert computer programme demands via a Tweetdeck tweet.

The flaw is called cross -site scripting and it’s always been possible to do it in Tweetdeck, just not enough people ever noticed before.

3. @Firoxl did the responsible thing

He told Tweetdeck and Twitter, and thousands of other people. As CNN reports, he tweeted:

Vulnerability discovered in TweetDeck. \ o /

The hacker community soon caught on. Step in *Andy.

4. Who?

*Andy (@derGeruhn on Twitter) caught on to the Tweetdeck vulnerability and tweeted this out:

andy

His tweet contained code which ordered it to be retweeted by other accounts (including yours truly’s account) and so the mayhem began.

5. And why did people see odd pop ups?

These cross-site scripting flaw discovered by @Firoxl meant that any cheeky divil exploiting the flaw could cause pop-ups to appear. While *Andy’s message was the most prevalent in terms of automatic retweets, other people saw things like:

Like BBC News, with its 10.1 million followers.
