By now most of the Twitter users probably heard Twitter was hit with a potentially harmful virus.
For those who did not see the posts around the net here is what basically happened.
StalkDaily had said they are not the orginator of the attack.
If you are infected do the following:
1. Go to your Twitter account settings and switch your bio back to the normal setting.
2. Clear out your cache and cookies from your browser.
3. As a precaution, change your Twitter account password.
Twitter was pretty fast on knocking this down and posted this their status page:
Earlier today we were informed of a malicious site that was spreading links to StalkDaily.com on Twitter without user consent via a cross-site scripting vulnerability. We’ve taken steps to remove the offending updates, and to close the holes that allowed this “worm” to spread.
No passwords, phone numbers, or other sensitive information were compromised as part of this attack.
