Android's Biggest Security Threat: OS Fragmentation

Mar 08, 2013 11:11 AM EST

Android Updates Through Carrier

Unless you bought the phone or tablet recently, odds are high that your Android device is running an outdated version of the operating system, exposing you to serious security risks.

The latest data from Google shows that 44 percent of Android users are still on "Gingerbread," or versions 2.3.3 through 2.3.7, which was released two years ago. Gingerbread has a number of security vulnerabilities which have been fixed in later versions. The OS breakdown data is based on statistics collected from Android devices connecting to Google Play from Feb. 22 to March 4.

Just 16 percent of Android devices are running version 4.1 or 4.2 of the mobile operating system, according to Google. Also known as "Jelly Bean," the latest Android version was released six months ago, but a majority of Android users have not been able to upgrade to the new OS because the process is tightly controlled by the carriers.

"The problem with Android is that most people have old versions on their phone," Collin Mulliner, a postdoctoral researcher with the SECLAB at Northeastern University in Boston, said during a mobile security panel discussion at last month's RSA Conference.

At our SecurityWatch Summit last fall, Dan Guido, CEO and co-founder of Trail of Bits, noted that the majority of iOS devices are updated within weeks, it not days, of Apple releasing the new operating system.

Mobile Carriers Lag on Updates
"One of the most important things in software security today is the ability to remotely update," Mulliner said on the panel. While users can initiate the operating system update on their own for iPhones and iPads, Android, mobile carriers control the entire process for Android devices. At the moment, their collective record for pushing out updates for users is absolutely dismal.

The problem is that Android's open platform allows device manufacturers and carriers to tweak the operating system to bundle extra software and set certain configuration settings. Whenever Google releases an operating system update, both the vendor and carriers have to test the changes against their home brew systems before rolling out the latest version. The carriers claim this is a slow process, but many security experts believe carriers are prioritizing profit over security.

Some phones just don't get the latest Android update because they are being phased out or are older models, Chris Soghoian, a privacy researcher and activist, said at a different event earlier this year. Manufacturers focus their efforts on devices currently for sale and coming to the market, and wireless carriers "only care about you once every two years" when the user contract is up for renewal, Soghoian said. For example, an LG Android smartphone didn't get its first OS update for 16 months, and many phones never even get that first update, let alone a second one.

Considering that Google has pushed out a new version approximately every six months, it's easy to see how quickly users can become out-of-date.

A drive-by attack, where the user is compromised just by visiting a malicious site, is not the biggest threat facing Android users, Charlie Miller, a researcher well-known for his work on iOS and Android security, said during the same panel at the RSA Conference.

"People think that drive-by is a big threat, but in real life they just don't happen," Miller said. When it comes to Android, the biggest risk facing users is the fact that their devices are running outdated and un-patched versions of the operating system, he said. The latest versions of Android have security patches and improved exploit mitigation.

Cyber-criminals know users are running vulnerable operating systems. All criminals have to do is release a malicious app exploiting a vulnerability in an old version of Android, and hit a significant chunk of the user base.

As Soghoian pointed out earlier, "You don't need a zero-day to attack most Android devices if consumers are running 13-month-old software."

Unfortunately, this situation is not likely to change unless carriers start taking security seriously, or Google wrests control of the update process away from the carriers. The most secure Android device around is the Nexus 4 smartphone from Google, as the company has full control over the updates.

(¯`·._.·Meri Tamanna·._.·´¯) Nice Logic - It May Work!!

 

Nice Logic - It May Work!! A man eats two eggs each morning for breakfast. When he goes to the Kirana store he pays Rs. 12 a dozen. Since a dozen eggs won't last a week he normally buys two dozens at a time. One day while buying eggs he notices that the price has risen to Rs. 16. The next time he buys groceries, eggs are Rs. 22 a dozen. When asked to explain the price of eggs the store owner says, "The price has gone up and I have to raise my price accordingly". This store buys 100 dozen eggs a day. He checked around for a better price and all the distributors have raised their prices. The distributors have begun to buy from the huge egg farms. The small egg farms have been driven out of business. The huge egg farms sell 100,000 dozen eggs a day to distributors. With no competition, they can set the price as they see fit. The distributors then have to raise their prices to the grocery stores. And on and on and on. As the man kept buying eggs the price kept going up. He saw the big egg trucks delivering 100 dozen eggs each day. Nothing changed there. He checked out the huge egg farms and found they were selling 100,000 dozen eggs to the distributors daily. Nothing had changed but the price of eggs. Then week before Diwali the price of eggs shot up to Rs. 40 a dozen. Again he asked the grocery owner why and was told, "Cakes and baking for the holiday". The huge egg farmers know there will be a lot of baking going on and more eggs will be used. Hence, the price of eggs goes up. Expect the same thing at Christmas and other times when family cooking, baking, etc. happen. This pattern continues until the price of eggs is Rs. 60 a dozen. The man says, "There must be something we can do about the price of eggs". He starts talking to all the people in his town and they decide to stop buying eggs. This didn't work because everyone needed eggs. Finally, the man suggested only buying what you need. He ate 2 eggs a day. On the way home from work he would stop at the grocery and buy two eggs. Everyone in town started buying 2 or 3 eggs a day. The grocery store owner began complaining that he had too many eggs in his cooler. He told the distributor that he didn't need any eggs. Maybe wouldn't need any all week. The distributor had eggs piling up at his warehouse. He told the huge egg farms that he didn't have any room for eggs would not need any for at least two weeks. At the egg farm, the chickens just kept on laying eggs. To relieve the pressure, the huge egg farm told the distributor that they could buy the eggs at a lower price. The distributor said, " I don't have the room for the eggs even if they were free". The distributor told the grocery store owner that he would lower the price of the eggs if the store would start buying again. The grocery store owner said, "I don't have room for more eggs. The customers are only buying 2 or 3 eggs at a time. Now if you were to drop the price of eggs back down to the original price, the customers would start buying by the dozen again". The distributors sent that proposal to the huge egg farmers but the egg farmers liked the price they were getting for their eggs but, those chickens just kept on laying. Finally, the egg farmers lowered the price of their eggs. But only a few paisa. The customers still bought 2 or 3 eggs at a time. They said, "when the price of eggs gets down to where it was before, we will start buying by the dozen." Slowly the price of eggs started dropping. The distributors had to slash their prices to make room for the eggs coming from the egg farmers. The egg farmers cut their prices because the distributors wouldn't buy at a higher price than they were selling eggs for. Anyway, they had full warehouses and wouldn't need eggs for quite a while. And those chickens kept on laying. Eventually, the egg farmers cut their prices because they were throwing away eggs they couldn't sell. The distributors started buying again because the eggs were priced to where the stores could afford to sell them at the lower price. And the customers started buying by the dozen again. Now, transpose this analogy to the gasoline industry. What if everyone only bought Rs 300.00 worth of Petrol each time they pulled to the pump? The dealer's tanks would stay semi full all the time. The dealers wouldn't have room for the gas coming from the huge tanks. The tank farms wouldn't have room for the petrol coming from the refining plants. And the refining plants wouldn't have room for the oil being off loaded from the huge tankers coming from the oil fiends. Just Rs. 500.00 each time you buy gas. Don't fill up the tank of your car. You may have to stop for gas twice a week, but the price should come down. Think about it. Also, don't buy anything else at the fuel station; don't give them any more of your hard earned money than what you spend on gas, until the prices come down..." ..just think of this concept for a while. .................please pass this concept around....reaching out to the masses...the world.....
