iOS 4.3.3 vulnerability exposed; experts advise you to stay away from suspicious PDF files
It is no secret that Android smartphones are a tempting target for malware and hackers, but iOS devices are not immune to attacks either. If you have an iPhone, iPad, or an iPod touch running iOS 4.3.3, you might want to restrain yourself from viewing any suspiciously-looking PDF documents as they might be hiding a nasty surprise in there.

According to the German government's IT security experts, a vulnerability found in iOS 4.3.3 that exploits the way the system handles PDF documents can allow for malicious software to be installed onto the device without the user's knowledge. Once successfully deployed, the malicious code can theoretically grant the attacker with root access to the system allowing them to read your messages, browse your contacts list, tinker with your camera, and pretty much do whatever they please with the device.

If this sounds like something that you have already heard before, you are not mistaken as a pretty similar flaw was found in iOS 1.1.1 about four years ago. The second major iOS release was not impenetrable either as an identical PDF vulnerability was present in it as well. Apple has yet to release a patch to fix the hole in iOS 4.3.3, but at this time, it seems like jailbreaking your device can fix the problem.

Fortunately, it has been reported that the security flaw has not caused any major damage so far, but despite that, it is advisable for you to be extra careful when browsing web sites that you do not trust. You do not want to be the first victim to make it on the list, now, do you?

My recommendation, just like any other OS never open files from not known sources, watch out for not so trusted web sites or weird or pirated apps and you will be fine. Now android friends could you keep the puns to yourselves and give the iPhone users an example that we have matters, maybe they will return the favor, thank you

Lol. What was that about IOS never having issues whatsoever, iFanboys? Come on, you're always full of glee when Android has an issue like this.

Exactly! When Android has issues iSheep are always quick to discredit Android saying that the Android OS is a poor OS. So now how are the iSheep going to make this iOS malware issue a non issue? Can't wait to see how this is all just an exaggerated non issue. lol Apple Fanboys will take this in stride because no OS is PERFECT & they know that! iSheep will take this news to another level, because “iOS NEVER gets malware". Let's see where this goes! I can't wait to hear all the reasons why iOS has "NO" issue at this time & how this is all a figment or our imaginations. lol

20+? Don't exaggerate. Besides, it's already been proven that Google has a quicker turnaround on fixing problems like this than Apple.

And this also comes in the wake of Lulzsec's remnants hacking Apple's servers.

iosmaster is a typical iSheep who lies & makes things up. A silly minded person how has nothing better to do than to fabricate things that are not true & lead the other iSheep to the same grounds he was grazing on. That fine herb makes iosmaster say silly things that are not too bright! Remember say NO to the herb Steve Jobs is feeding you! Maybe the iSheep should just stick with hay & grass not the fine herb. lol With all kidding aside in one word to describe iosmaster’s comment “DELUSIONAL”! lol
