New mobile threat families and variants rose by 49% from last quarter, from 100 to 149. 136, or 91.3% of these were Android and 13, or 8.7% Symbian. Q1 2013 numbers are more than double that of a year ago in Q1 2012.
While the “walled-gardens” of the iOS and Windows Phone, where apps require approval before sale, have prevented malware threats to develop for the iPhone or Nokia models running those systems, Android threats are increasing and becoming more likely to affect average users.
“I’ll put it this way: Until now, I haven’t worried about my mother with her Android because she’s not into apps,” F-Secure Security Advisor Sean Sullivan said. “Now I have reason to worry because with cases like Stels, Android malware is also being distributed via spam, and my mother checks her email from her phone.”
You can get the entire report here and as you read through it, listen to our Chief Research Officer Mikko Hypponen and Sean Sullivan walk through the report in this exclusive preview. (Sorry, there is a odd echo for the first few minutes of the recording.)
Here’s a look at profit-motivated threats. Is anyone surprised that mobile malware authors are mostly motivated by money?
As far as the types of threats our Labs is seeing, Trojans continue to dominate:
In Finland, there is this thing called juhannus. A few years ago, our former colleague Hetta described it like this: Well, Midsummer – or juhannus – as it is called in Finnish, is one of the most important public holidays in our calendar. It is celebrated, as you probably guessed, close to the dates of the Summer Solstice, when day is at its longest in the northern hemisphere. Finland being so far up north, the sun doesn’t set on juhannus at all. Considering that in the winter we get the never ending night, it’s no surprise we celebrate the sun not setting. So what do Finns do to celebrate juhannus? I already told you we flock to our summer cottages, but what then? We decorate the cottage with birch branches to celebrate the summer, we stock up on new potatoes which are just now in season and strawberries as well. We fire up the barbecue and eat grilled sausages to our hearts content. We burn bonfires that rival with the unsetting sun. And we get drunk. If that isn't vivid enough, this video may help: [protected-iframe id="f18649f0b62adf8eb1ec638fa5066050-10874323-9129869" info="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2Fsuomifinland100%2Fvideos%2F1278272918868972%2F&show_text=0&width=560" width="560" height="315" frameborder="0" style="border: none; overflow: hidden;" scrolling="no"] And because the celebration is just so... celebratory, it's easy to lose your phone. So here are a few ways to prepare yourself for a party that lasts all night. 1. Don't use 5683 as your passcode. That spells love and it's also one of the first passcodes anyone trying to crack into your phone will try. So use something much more creative -- and use a 6-digit code if you can on your iPhone. You can also encrypt your Android. 2. Write down your IMEI number. If you lose your phone, you're going to need this so make sure you have it written down somewhere safe. 3. Back your content up. This makes your life a lot easier if your party goes too well and it's pretty simple on any iOS device. Just make sure you're using a strong, unique password for your iCloud account. Unfortunately on an Android phone, you'll have to use a third-party app. 4. Maybe just leave it home. Enjoy being with your friends and assume that they'll get the pictures you need to refresh your memory. And while you're out you can give your phone a quick internal "clean" with our free Boost app. [Image by Janne Hellsten | Flickr]
Collision is coming to a close today, and what a week it’s been. F-Secure’s Chief Research Officer Mikko Hyppönen was there earlier in the week, and gave a compelling talk on the evolution of cyber crime. He also gave a quick post-talk interview, so check out this Quickfire article to learn who Mikko thinks deserves a slap in the face. F-Secure also ran a basic Wi-Fi experiment at Collision*, similar to ones conducted in 2014 and 2015. While the experiment conducted at Collision had a smaller scope than our previous investigations, it does prove that people are still pretty promiscuous when it comes to connecting to public Wi-Fi hotspots without the proper protection, such as a VPN. In the first two days of Collision, we observed nearly one hundred people connecting to a phony Wi-Fi hotspot. And none of them were encrypting their traffic. Connecting to a phony Wi-Fi hotspot can open the door to all kinds of problems. Hackers have been known to use similar setups to help them “sniff” people’s Internet traffic, allowing them to do things like read personal messages, log the websites people visit, and even steal passwords and other sensitive information. So if you make a habit of using public Wi-Fi hotspots – whether you’re at a tech conference, an airport, a café, or a hotel – you should give Freedome a try to keep you and your private data safe and secure.

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!
