Big News (yawn) – Twitter Hacked, Fixed?

Twitter Hack – What, how and what’s next from Symantec Hosted Services

How – The “hackers” used a new exploit of a flaw in JavaScript which took advantage of the way Twitter handled Javascript updates.  Most of the exploits seen used the “onmouseover” trigger, which meant that all a user had to do was move the mouse over a tweet and the code would run*.

Most would just repost the same thing to your own wall, some would repost and redirect the user to another site. There were some examples of users being redirected towards porn sites. The fact it only needed a cursor to move over it is why it spread so very rapidly all over the world, before people knew what was happening.

What Now?Twitter appears to have fixed the flaw, so users should be safe.  Those who are still concerned, can disable Javascript in their browser, or use a client program (such as an smartphone app) to access Twitter as these are not affected by the exploit.

* emphasis mine.

Huh. Using social networking sites can be dangerous to your computer. Who knew? (Actually folks, the Evil Doers can do this to pretty much any website. They’re just targeting Twitter and Facebook because that’s where the people are.)
