Report: 99.7 percent of Android Phones Contain Security Hole

May 18, 2011 -

A new report claims that around 99.7 percent of phones using Google's mobile operating system contain a security hole that can enable hackers to send unencrypted personal data. Mobile devices using the Android operating systems have a weakness that could allow hackers to gain "full access" to private information such as calendar, contact information, and "private web albums,” according to a research group from Germany's University of Ulm. The security hole could also give hackers the ability to view, modify or delete contacts, calendar events, and private pictures. Thankfully, the security flaw only affects individual phones.

In a new research paper, researchers at the University of Ulm detailed the flaw, testing it for vulnerabilities. They found that some Android applications could transmit unencrypted data, allowing others to "eavesdrop" any of the transmitted information. Researchers were tested to see if they could hack into Android data using a simple third-party application. Apparently they found a lot of success in completing the exercise.

“We wanted to know if it is really possible to launch an impersonation attack against Google services and started our own analysis,” researchers said. “The short answer is: Yes, it is possible, and it is quite easy to do so.”

The hack was tested on various versions of the Android operating system including 2.1, 2.2, 2.2.1, 2.3.3, 2.3.4 and 3.0. Phones used in the test included the Nexus One, HTC Desire, HTC Incredible S, and newly released tablet the Motorola XOOM.

IanCWin 8 isn't bad, it just can't decide whether to be a desktop OS or a tablet OS.09/30/2014 - 2:40pm
IanCI think its a way of getting round giving it free to Win 8 users...09/30/2014 - 2:39pm
MaskedPixelanteWindows alternates between bad and good versions. XP was good, Vista sucked, 7 was good, 8 sucked, therefore 10 will suck, QED.09/30/2014 - 2:18pm
E. Zachary KnightPerhaps they are calling it "10" because on a scale of 1-10 of how awesome it is, it is a clear 10.09/30/2014 - 2:06pm
E. Zachary KnightTo be fair. Microsoft has had a bit of a numbering issue lately. What with going from XBox 360 to XBox One.09/30/2014 - 2:06pm
NeenekoI remember the pac man show from the 80s, but I was more picturing this: https://www.youtube.com/watch?v=fWL6j0SvqV0 which is probably more source accurate then Tetris will be...09/30/2014 - 1:42pm
Andrew EisenThat is so dumb. That would be like Sony saying, "Hey guys! The next Playstation is going to be so awesome, so far beyond what the PS4 can do that we're going to call it the Playstation 6!"09/30/2014 - 1:42pm

E. Zachary KnightThere is actually a Pacman tv show and it isn't bad. My kids like it.09/30/2014 - 12:53pm
NeenekoTetris.. the movie? It is sad when a joke becomes real. Next up pacman and minesweeper!09/30/2014 - 12:42pm
Andrew EisenIt remixes existing content into different scenarios, yes.09/30/2014 - 12:34pm

MaskedPixelanteThe phasing out of the iPad 2 begins. Pokemon TCG Online REQUIRES an iPad with a retina display to run.09/30/2014 - 12:05pm
Andrew EisenIf you can't get enough of Hyrule Warriors' gameplay, yeah, it's looking like a pretty good deal.09/30/2014 - 12:03pm
E. Zachary KnightSo a Tetris movie is happening. Here is the link. Reads like a joke: http://blogs.wsj.com/speakeasy/2014/09/30/tetris-movie/09/30/2014 - 11:47am
E. Zachary KnightSo is it worth getting the Season Pass?09/30/2014 - 11:45am
Andrew EisenWow. The Hyrule Warriors DLC is more extensive than I thought. The new scenario in the first pack is a full five levels and the new Adventure Map is a whole new map, all 128 squares. Yowza!09/30/2014 - 11:08am
Andrew EisenI'm most pleased that the Quick Start Menu will now launch when the Wii U is powered on from the TV Gamepad TV Remote. I felt that was a huge oversight and I'm glad it's been corrected.09/30/2014 - 11:06am
MaskedPixelanteHey look, Nintendo figured out folders on the Wii U. I mean, yeah, they figured out folders on the 3DS several years ago, but these are BETTER! These... uhh... actually display the full folder name on the home screen instead of just the first letter...09/30/2014 - 9:19am
