Android devices security problems: At risk of hacks through text messages

It used to be that a text message is a way to communicate with people, but now it appears that it can carry malicious files that can hack somebody's phone.
A mobile security team has uncovered a major flaw in Android phones, putting 95% of users and millions and millions of gadgets at risk of hack attacks.
The bug, called "Stagefright" from Android's media library, is dubbed as the popular mobile operating system's (OS) worst security flaw discovered ever, Fortune reported.
The bug, which affects Android phones running on version 2.2 and onwards, was announced last July 21 by Zimperium, a mobile security company, during the annual BlackHat conference.
The malicious program that would attack Android is embedded in a short video, which will be sent to a person through a text message, according to a report from NPR.
As soon as the receiver gets the infected text, Stagefright features prepare the video for viewing.
But apparently, as the program processes the video, that would be the time that hackers take the opportunity to take control over the phone, hijacking it and stealing data.
The worst part is that the user won't even know that a hack attack has already happened.
According to Zimperium Vice President of Research and Exploitation Joshua Drake, the attacker can even delete the infected message before the victim notices.
"These vulnerabilities are extremely dangerous because they do not require that the victim take any action to be exploited," Drake stated in the company's blog post.
In a blog post from Twilio, there were tips that can lessen the risk of being vulnerable and these commonly point to disabling the automatic download of files sent through Multimedia Messaging Service (MMS).
However, doing the abovementioned step will only "partially" solve the problem. Android devices remain vulnerable to attacks as long as the bug exists. The complete solution will only come from a patch intended for the device.
According to CNET, Zimperium told National Public Radio that hackers have not taken advantage of the Android flaw so far.
Nevertheless, disabling the auto-download or auto-retrieve features should help in the meantime.

Microsoft changes 'Outlook Web Access' to 'Outlook on the web'

The branding gurus are really earning their wages down Redmond way Outlook for the Web's new weather-enabled calendar app 14 5 Aug 2015 at 02:58,  Simon Sharwood Fresh from showing glimpses of the next-generation Outlook Web Access client in a preview of Exchange Server 2016 , Microsoft has now detailed just how the new version of the browser-bound Outlook will work. There's a new name for starters: “Outlook Web Access” is now “Outlook on the web”. Those marketers sure are earning their wage! Microsoft saying all the usual stuff about the revision making you more productive. The feature touted as making the greatest contribution to that cause is the new “Action toolbar” that “provides quick access to the most common commands, whether you are clearing out your inbox, replying to an email, or adding an event to your calendar.” One of the things you'll see on the toolbar, depicted below, is the “Sweep” command. That's come from Outlook.com and “provides a simple set of act...

Microsoft upgrades its Surface tablets to Windows 10

By
Consumers interested in buying one of Microsoft's Surface tablets will now find it with Windows 10 preinstalled. Microsoft's  online page  for its lower-cost Surface lineup shows that the tablet now comes with Windows 10 Home edition. The page for the pricier and beefier Surface Pro 3  indicates that they're outfitted with Windows 10 Pro edition. Microsoft has been on a tear to push out Windows 10, partly to make up for the poor response to Windows 8 and partly to get as many Windows users as possible all on the same platform. The company has been offering Windows 10 as a free upgrade to Windows 7 and 8.1 users for the first year. Last Thursday, Microsoft announced that the new OS was  running on 14 million devices  since its official launch the previous day. Now the challenge is to get PC and tablet makers to outfit their new devices with Windows 10. Microsoft certainly would want to lead the way, so it's natural for its own Surface tablets to now be sporting W...
