Firewall design flaw exposed, potentially dangerous to smartphones
Although the following news is by no means a cause for alarm, internet security experts are keeping a close eye on the matter. That is because a flaw in firewall design could potentially allow for smartphone data traffic to be hijacked. As a result, phishing scams, misleading messages, and other kinds of mischief may plague the targeted device exposing the unsuspecting user at risk.

The flaw was discovered by analysts at the University of Michigan, who clarify that the way firewalls work is causing all the trouble: "the more checks the firewall performs, the more information it can leak." And we are talking about firewalls used by carriers: firewalls that are meant to stop malware from getting onto users' smartphones. At least 48 carriers are known to be potentially vulnerable to the flaw. These are the carriers using firewalls from Check Point, Cisco, Juniper, and other networking experts, and AT&T is among them.

We have yet to find out whether this is a security flaw that truly exposes our smart devices to risk. Those who use an Android device are advised to run security checks with the help of an antivirus application. Windows Phone and iPhone owners should not be affected as the platforms do not allow execution of unsigned code. Plenty of further information, including technical details and examples of how the exploit works, is available at the source PDF document below.

Then explain why the military and huge companies are using Android? Oh right, because iOS is for kids and no one will want to hack a kid's OS.

Ok, I'll take that second change...like megadirk said, Android won't install anything you don't allow it to..., so basically if someone was an idiot...like you and just installed and allowed any app to be installed,... they're just asking for it...it doesn't matter if the OS is secure or not, just if the user is an idiot or not...Was that so hard to understand?... Kid OS fanboy?

so then this article has no place here in PA as most of you don't allow it? it should run in the newspaper so the Android users that don't visit tech websites can see this. Agree with you on that you should never allow downloads from xyz places , but you know what it happens and it happens as often that is an issue here.. making it unsecure, which brings me to my point. Android is unsecure... for most people..

don't waste your time talking to an android user, android its like a public WC every one can s**t in it.
IOS control each application before put it in apple store ... for that reason APPLE IS MORE SAFE THAN ANDROID

The unassigned code that will be supposedly installed, once again, will have to be allowed by the user. Nothing gets installed without the user's say so on any current mobile OS, even if you have the "allow unknown sources" box checked on the Android OS.

a jailbroken IPHONE is more safe than a brand new non rooted Android.
