I read an article yesterday on how RIM is in trouble because of the triple threat of IOS, Android, and Windows7 Mobile (ok, ok, so it was really only a double threat). I'll provide a source for the article later.
Well fast forward one day to the entry of 2011, and what do I see? An article talking about a "malicious trojan" that could compromise data stored on Android powered smartphones. This follows on the heels of an article I read earlier in the year about a virus that affected Jailbroken iPhones.
So I started this blog entry all set to crow about the safety of my beloved Blackberry over other smartphone OSes, but of course like a good analyst, I needed to back up my theory with research.
Unfortunately, it didn't take long for me to change my blog entry title away from something trumpeting the virtues of Blackberry OS, to something a bit more even keel.
So is the Blackberry OS susceptible to viruses? Well, apparently not so far. While there have been a demonstrated couple of exploits, one dating back to 2006, none of these exploits have been able to replicate, which is a key feature of viruses. But the Berry is definitely susceptible to malware - malicious software written to compromise a user's smartphone in some way. The difference is that users have to consciously download malware, and run the application in order for the malicious code to run and wreak havoc. This includes a trojan that can send out SMS texts to premium rate numbers. You can mitigate many of the problems that could come up by either blocking third party apps, or by restricting what third party apps can do within your security settings. Mind you this is more of a probability on BIS, since I would image that most IT departments shut down 3rd party apps on BES.
So what about Android? Is it susceptible to viruses? I'll go with a resounding "Yes" for final Jeopardy, Alex! The first Android virus was found back in August, and did the same thing as the aforementioned BB virus, namely sending out SMS texts to premium rate numbers. The most recent virus does not so nice things like Send location coordinates (fine location), Send device identifiers (IMEI and IMSI), Download and prompt the user to install an app, Prompt the user to uninstall an app, Enumerate and send a list of installed apps to the server. Fun times.
So what about IOS? I mean by now I'm sure we've all heard about Rickrolling - part of which refers to the Iphone virus that installed Rick Astley's pic as the wallpaper on jailbroken iphones, and changes the ringtone to "never gonna give you up". Not exactly a very serious virus, but a virus nonetheless. Plus as my pal Sharon just pointed out, there was another iphone virus that came out at pretty much the same time where a Dutch hacker was able to send a message to people with jailbroken iphones.
So what's the conclusion? Perhaps not surprisingly (considering its open source), Android seems the most vulnerable to exploits, followed by the iPhone and Blackberry. In fact, if the iPhone is not jailbroken, it actually seems to be the safest choice. Sort of throws a bit of a different spin on things. At the end of the day though, regardless of your smartphone of choice, clearly a few "safety first" object lessons apply;
- Only download apps from trusted sources.
- Familiarize yourself with your phone's security settings (passwords, application rights, etc) and make sure that you've made the changes that need to be made (e.g. change default passwords!).
- If your phone is capable of multi-tasking, make sure you are aware of all applications that are running, both in the background as well as the foreground, and that you know what they are doing.
Any other thoughts or comments? Happy to hear them.
Peace.
