Mobile Threat Report Q4 2012: 96% of all Mobile Malware written at the end of 2012 targets Android

mobile_report_q4_2012F-Secure Labs Mobile Threat Report for Q4 2013 is out and it’s clear that the most popular smartphone operating system is also the leading target for online criminals.

94% of all mobile malware the F-Secure Response Labs analyzed in Q4  targets Google’s Android platform.

You can get the whole report here.

Here’s what the growth of mobile mobile malware looks like over 2012.


As Android threats have grown, Symbian malware has nearly disappeared. Why? Symbian which used to be the world’s most popular mobile OS is disappearing. Nokia phones are increasingly moving to Windows Phone, which — as you may have noticed — is attracting no threats. The world’s second most popular mobile platform Apple’s  iOS for iPhones and iPads also had no threats found in 2012.

Why the difference? It comes down to platform openness and App store security.

How can you protect your phone from these threats?

1.  Stick to the official app stores.
Apple and Microsoft have strict guidelines for their app stores and Google’s Play store is increasingly adopting restrictions that prevent bad apps from ever showing up. If you only get apps in the official stores, your chances of getting a bad app are almost zero.

2. Check out reviews.
Malicious apps are often weeded out by active users who rate and review software. If an app doesn’t have positive feedback and a lot of it, you probably don’t want to be the one who tests it out.

3. Keep your phone’s software updated.
Your smartphone is a mini PC with the same software issues that your PC has including software that continually needs to be updated. This may require some help from your carrier depending on your phone —  but the basic rule is: The more current, the better.

4. Be very careful when giving your mobile number out.

The main thing to keep in mind is that while your family and friends may want to pry on your phone to see what you’re up to, the most likely reason a criminal will be targeting you is pretty obvious.

You guessed it: FOR THE MONEY.

Spring clean your PC and Android devices

Why Buy A New Device When You Can Spring Clean Your Old One?

The sun is out, the days are longer, and flowers are blooming. Spring has sprung - and with it, the perfect inspiration for cleaning, organizing, and getting rid of clutter. Whether or not you tackle your home this spring, at least take care of cleaning your PC and mobile devices - they need it too. Over time, computers and devices get bogged down by use and cluttered up with files you don't really need. This built-up junk makes them slow and unstable. Often people think they need to go buy a new device, when actually they just need a tune-up. With a little optimizing, you can get your old device running like new again. Here are the top three ways a good spring cleaning will help you get more out of the life of your device. 1. More space Are you running low on space on your device? No matter how much disk space a device has when it's new, over time it starts to run out. Apps, app data, large media files, downloads, and other unused user data start to litter your device. You might find your device is out of space for your photos, or you can't install any more apps. Cleaning up this excess junk will free up space for the content that you really want. 2. Faster performance Is it taking too long for your PC or phone to boot up? Too many processes running in the background that are dragging down your gaming or media experience? If your device is running slow or if apps are taking too long to start up, you could use an optimization for faster start-up times, browsing, file operations, and making your apps run smoother. 3. Better battery life Wouldn't it be nice if your batter would last a little longer? Your device's battery gets consumed by unnecessary apps and processes. By closing those out, you can extend your battery life so you don't need to plug in as often. Now, for the cleanup. There are some easy things you can do to get a cleaner, faster, more efficient device that's got space for the content you care about. Here are some easy steps: Photos and videos are some of the biggest space takers. You can free up a lot of space just by going through and individually deleting out the photos you don't want or need anymore from your gallery. Or you can back all of them up to another hard drive or cloud service, then remove them from your device altogether. Uninstall apps you don't use (Be strong! If you really need it down the road, you can always install it again). Open your Downloads folder and check what's there - chances are there's a lot of stuff you don't need anymore that you can delete. Clear your cached data from apps and browsers. This data is saved to enable quicker processing, but over time it all adds up and bogs your system down. Tip: Aside from the photos and videos, the quickest, easiest way to take care of the above items is to run a free cleaning with F-Secure Booster. It will get rid of all the old trashed files, temporary and log files and unused user data, to free up space for the stuff that really matters. The PC version of F-Secure Booster even has a software update tool to make sure all critical software and driver updates are taken care of. Ah, the beauty of spring...when everything old is new again!

WhatsApp is now secure by default – Why is it so important?

WhatsApp is not just any messaging app. It’s a quite unique combination of popularity and security. Many people know it as “the” messaging app. A natural choice that all your friends are using already, so it’s a no-brainer for you to use it too. But WhatsApp is also committed to provide a secure solution. They have been working with Whisper Systems for a long time and gradually integrated their security technology. This work reached an important milestone yesterday when WhatsApp announced that all communications now are end-to-end encrypted, if the parties use the latest version. This level of encryption has previously been available in some situations, but now they have reached full coverage. This is actually a very important milestone for all of us. Not only for the WhatsApp users who really care about security. Let’s take a look at what this means. What is end-to-end encryption? This means that the message is encrypted during the whole path from sender to receiver. The end-point devices handle encryption and decryption and the message is not readable in transit or when stored on the vendor's server. The vendor does not have a key to the encryption and can’t read the messages, nor reveal them to authorities. Is it hard to use? No. WhatsApp’s encryption is fully integrated and automatic. It’s enabled by default and you do not need to do anything. Except make sure that all communicating parties have the latest version of WhatsApp, but that will eventually happen anyway when people upgrade their apps. Why is this important? WhatsApp is a leader is what we call secure by default. This is a very important trend as it helps us all stay secure. There will always be secure ways to communicate, even if strong end-to-end encryption would be banned in some countries. But using security tools that aren’t mainstream will always make you look suspect. There’s a lot of ways to detect them using network surveillance. Outsiders will not be able to read what you write, but authorities may still conclude that you have something to hide and start keeping an eye on you. Even if your business is perfectly legit and honorable. This is why secure by default is important. If the norm is to use a secure communication channel, then nobody can claim you are suspect because you use one. The masses who don’t care about security are actually helping those who really need it. Other examples of secure by default are Apple’s iMessage and mail traffic that to an increasing degree default to protected connections using SSL or TLS. Is WhatsApp really secure enough? They are definitively serious about providing a secure solution. But we should always keep in mind that there are flaws in every existing system. Vulnerabilities will no doubt be discovered, and fixed promptly. But WhatsApp should anyway have sufficient security at least for people with low to medium needs. If you have a serious need for security, then you should investigate your needs thoroughly and carefully select what tools and methods you use. Consult professionals and keep in mind that security is a broad concept. Selecting the right tool is not enough. You also need to have good op-sec. You need to mind what you say and do, and how you handle data. Isn’t WhatsApp helping terrorists by doing this? No, not really. Properly encrypted communications is no doubt an obstacle for investigating authorities. But there are so many other tools they can use instead. Like tapping phones and locations. Searching facilities. Tracking persons and vehicles. And using spying implants on devices. As WhatsApp puts it in the announcement: “No one can see inside that message. Not cybercriminals. Not hackers. Not oppressive regimes. Not even us. End-to-end encryption helps make communication via WhatsApp private – sort of like a face-to-face conversation.” So yes. They could have included “Not investigating authorities” too, and that is a minor disadvantage in cases where we are dealing with terrorism and other kinds of sever criminality. But the overall picture is perfectly clear. The benefits of end-to-end encryption and secure by default clearly outweighs the disadvantages. Kudos to WhatsApp for showing the way.   Safe messaging, Micke     Public domain image from Pixabay
