We Protect You: Timo Hirvonen, Anti-malware Analyst

This is a guest post from an expert from F-Secure Labs. Enjoy!

My name is Timo Hirvonen and I work in the F-Secure Labs as Anti-malware Analyst. I have two major areas of focus in my work: exploit prevention and F-Secure DeepGuard.

Exploit analysis and prevention is my passion, and I love the challenge it offers.

I find fighting against exploits important; nowadays exploit kits are the main infection vector so no matter how safely and wisely you browse you might still get infected. By stopping the exploits, we block the attacker from executing any code on the victim’s computer, which in turn protects against many kinds of threats: ransomware, banking trojans – you name it.

The second cool part of my job is working with the F-Secure DeepGuard technology. I try my best to make sure it offers our Security Response the best possible tools to fight current and also future malware. The main idea behind DeepGuard is simple but extremely powerful: it monitors the behavior of unknown applications. Modern malware evolves quickly, and often each user gets infected by a unique copy of the malware. This poses a challenge for traditional detection technologies.

For DeepGuard, however, this is not a problem since there is one trait that all malware have in common: they exhibit malicious behavior. It is really an awesome technology, and we have had great results in protecting our users from serious threats like the infamous banking trojan Zeus.

Working in the F-Secure Labs was a dream of mine even as a teenager. I have now been with F-Secure for little over two years, and I can say it feels great to first work hard with all the talented the people in the Labs to solve some challenge, and then get the reward of seeing the fruit of your labor protecting all our users out there.

I can truly say that my job is a dream come true.

You can try out Deep Guard as part of our Internet Security 2013.

Why your Apple Watch will probably never be infected by malware

On Tuesday Apple announced its latest iPhone models and a new piece of wearable technology some have been anxiously waiting for -- Apple Watch. TechRadar describes the latest innovation from Cupertino as "An iOS 8-friendly watch that plays nice with your iPhone." And if it works like your iPhone, you can expect that it will free of all mobile malware threats, unless you decide to "jailbreak" it. The latest F-Secure Labs Threat Report clears up one big misconception about iOS malware: It does exist, barely. In the first half of 2014, 295 new families and variants or mobile malware were discovered – 294 on Android and one on iOS.  iPhone users can face phishing scams and Wi-Fi hijacking, which is why we created our Freedome VPN, but the threat of getting a bad app on your iOS device is almost non-existent. "Unlike Android, malware on iOS have so far only been effective against jailbroken devices, making the jailbreak tools created by various hacker outfits (and which usually work by exploiting undocumented bugs in the platform) of interest to security researchers," the report explains. The iOS threat that was found earlier this year, Unflod Baby Panda, was designed to listen to outgoing SSL connections in order to steal the device’s Apple ID and password details. Apple ID and passwords have been in the news recently as they may have played a role in a series of hacks of celebrity iCloud accounts that led to the posting of dozens of private photos. Our Mikko Hypponen explained in our latest Threat Report Webinar that many users have been using these accounts for years, mostly to purchase items in the iTunes store, without realizing how much data they were actually protecting. But Unflod Baby Panda is very unlikely to have played any role in the celebrity hacks, as "jailbreaking" a device is still very rare. Few users know about the hack that gives up the protection of the "closed garden" approach of the iOS app store, which has been incredibly successful in keeping malware off the platform, especially compared to the more open Android landscape. The official Play store has seen some infiltration by bad apps, adware and spamware -- as has the iOS app store to a far lesser degree -- but the majority of Android threats come from third-party marketplaces, which is why F-Secure Labs recommends you avoid them. The vast majority of iPhone owners have never had to worry about malware -- and if the Apple Watch employs the some tight restrictions on apps, the device will likely be free of security concerns. However, having a watch with the power of a smartphone attached to your body nearly twenty-four hours a day promises to introduce privacy questions few have ever considered.
