The Myattwg.att.com website has been observed as part of annoying redirects that occur when users try to access many popular websites, including Gmail, YouTube, eBay, etc. Instead of the intended destination, users are taken to the https://myattwg.att.com/UverseAccount.html website. Trying to use a different Web browser will not stop the Myattwg.att.com redirects from happening. Being prevented from accessing many of your most visited Web destinations could be beyond frustrating, and many users could even feel that they are unable to browse the Internet at all.
It is not surprising that many would consider Myattwg.att.com to be part of a malware attack or other threatening activity, after experiencing the negative consequences of seeing the page. However, this is not the case. The Myattwg page is perfectly legitimate, and it belongs to AT&T, the American multinational telecommunications giant. The site appears to be connected to AT&T's attempts to limit the Internet bandwidth to those who have failed to pay their bills.
The problem is that the messaging displayed on the Myattwg page doesn't make that immediately obvious. Instead, the site appears to have more in common with popular phishing or technical support schemes, even though it is perfectly safe. When users see that they are urged to call several provided numbers and to inform their myAT&T user IDs and passwords to resume normal browsing, they would naturally be suspicious. In conclusion, users experiencing redirects to Myattwg.att.com are unlikely to be a victim of a malware attack and should instead check if they do not have any outstanding payments due for their AT&T bills.
