The hacking group TeaMp0isoN claims to have compromised Web servers used by T-Mobile, and absconded with account information for company employees, including members of T-Mobile's media team.
The group used a post on its official Twitter account taking responsibility for the attack, which targeted a T-Mobile Web server that hosted part of the company's Web page, including its media relations information. User names, e-mail addresses, phone numbers and passwords for around 80 T-Mobile staff were also posted, including what appear to be a dispiriting number of default passwords.
The leaked information was posted Saturday. However, the attack appears to have occurred in October, judging from date and time stamps on the leaked data, which appeared on pastebin.com.
T-Mobile did not immediately respond to requests for comment and could not confirm the breach. A Web page hosting the company's media relations contacts was offline temporarily on Sunday and early Monday, but was back in service by Monday afternoon.
In an e-mail response, a T-Mobile spokesperson said that the company's newsroom "experienced a security issue last week." No other T-Mobile Web properties were affected by the breach, however.

Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
