Prepare!

!!! PLEASE REFRAIN FROM VISITING CINGULARONE.COM !!!

Alright, I have (and many others) given fair warning to AT&T, but the issue has not been addressed. Time to shed some light on the fact that AT&T's CingularOne.com website has been hijacked, and is currently hosting a JavaScript exploit that loads content from remote malicious domains.

Here's some visual proof:

Again, please refrain from visiting AT&T's CingularOne.com website until this issue has been fixed.

However, if you just must sneak a peek, then disabling JavaScript and inline frames should mitigate any infection vectors. But to be safe, ensure your anti-virus on-access scanning is enabled, and your AV definitions are updated.
