Now a security research firm has uncovered a set of vulnerabilities within the Android operating system called Stagefright which prompted him to say: 'If Heartbleed from the PC era sends chill down your spine, this is much worse.' What is Stagefright? Link to this article from your site or blog.Last year the world went into meltdown worrying about the Heartbleed vulnerability which exposed a fundamental element of internet communications to hacking attacks, and prompted national newspapers in the UK to cry ' CHANGE ALL YOUR PASSWORDS'.

Only if enough end users make enough noise will this extremely dangerous bug be fixed. But consumer and small business users of Android have only one hope.Д¬all the maker of your Android device, and your cellular carrier, and demand to know when the Stagefright fix will be pushed to your device. Enterprise customers of ZimperiumвЂ™s Enterprise Mobile Threat Protection solution, zIPS, are also protected against Stagefright vulnerabilities. In addition, if you've rooted your phone and installed CyanogenMod (a custom version of the Android operating system), you're okay. Users of SilentCircleвЂ™s high-security Blackphone running PrivateOS v1.1.7 or higher are safe. Once the official fix is applied, you can turn auto-retrieve back on.ДЄt least two group of users are already protected against Stagefright exploits, says Zimperium. (Google for instructions specific to your handset.) Doing this will require you to explicitly click to view a multimedia message, if one arrives from a person you don't know.

In the absence of a software fix from your carrier, one thing you can do to mitigate the risk is to turn off the 'auto-retreive' option for MMS messages on your phone. Devices older than 18 months are unlikely to get updates at all, because youвЂ™re expected to buy a new device every two years. Once theyвЂ™ve sold you a phone, these middlemen have little incentive to keep your copy of Android updated and secure. Those middlemen customize Android to their liking before installing their tweaked versions on devices and selling them. New versions of вЂњpureвЂќ Android go to device manufacturers and cellular service carriers.

One More Hurdle.Д«ut Google doesnвЂ™t update Android devices directly. All copies of Android obtained directly from Google are now safe from Stagefright. To GoogleвЂ™s credit, the patches were applied to the companyвЂ™s internal вЂњworking copyвЂќ of Android within 48 hours. In an unusual move, Zimperium created patches for the Stagefright vulnerabilities and gave them to Google along with ZimperiumвЂ™s documentation of each vulnerability. Android versions earlier than Jelly Bean (roughly 11% of all devices) are especially vulnerable.

However, native code executes faster, which is important for displaying multimedia thatвЂ™s why C++ was chosen for this portion of Android.ДЄndroid versions 2.2 and later are vulnerable even the latest Lollipop 5.1.1 version contains this alarming flaw.

Stagefright is written in so-called вЂњnative code,вЂќ (specifically, C++), which is more susceptible to this sort of memory corruption than languages such as Java, which were designed with memory-security in mind. The vulnerabilities (yes, plural) were discovered in an Android module code-named вЂњStagefright,вЂќ whose job is to display common multimedia files. The implanted malware can quickly erase any notification of the treacherous MMS message, and even the message itself. But this attack can take place while youвЂ™re not even looking at your phone.

You can protect against phishing messages and rogue Web sites by not clicking on suspicious file attachments, links, and download buttons. The really scary thing is that this attack does not require any action on the victimвЂ™s part. The malware can then take over complete control of the device, and even erase all signs of its invasion. The malformed message overloads a vulnerable part of the deviceвЂ™s memory, essentially creating a вЂњholeвЂќ in AndroidвЂ™s defenses through which malware can be injected. Here is how it can happen:ДЄ bad guy need only send a specially-crafted MMS message to a target device. Researchers with Zimperium Mobile Security recently discovered a flaw in 95% of Android devices (of which there are an estimated 950 million) that allows hackers to remotely execute malware on a device if they only know its phone number.
