Why your PC needs a great goal keeper

What is the value of superior detection rate? Does it really matter if your security software, your goal keeper, blocks close to 100% or close to 90% of malware attacks?

A simple answer – yes!

On average, one out of ten new zero-day malware attacks succeed as the detection software cannot anticipate the upcoming hits to the goal. The accrued costs to the company of all the related work and possible data loss are huge.

Let’s play with the numbers a bit:

  • With 500 employees, assuming they each face two malware per year, the company would face up to 1000 malware per year. If you have an industry average goal keeper who only blocks 92% of the attacks, this means about 80 successful hits into the goal.

80 malware that hit the goal will mean a lot of money. Both the external and internal costs can be significant. Internally, the detection, recovery, investigation etc will take a lot of time from your security officers and affected employees. However, the external repercussions can be even more staggering. Or how would you value information loss, business disruption, or revenue loss?

Neither can you sit back and relax thinking that you or your company are too small and insignificant for the attackers to target you. The game is on every day and regardless of the opponent. 79% of malware attacks are opportunity based. This means that anyone can be a target, it is just a question of who is the easiest one. The team with a weak or average goal keeper is a much easier to win over than the one with a superior goal keeper.

Malware is constantly evolving, with new tricks and features, just like the players on the field come up with new tactics to win the game. It is the popular software that is most often targeted, both based on known vulnerabilities and with new threats. So today, it is just as critical to be able to identify the clean, non-malicious software to be able to focus attention on the harmful attacks as it is for the goal keeper in the game to see the whole field to anticipate the next attack.

Think then: what if you had a super goal keeper that blocks even new or emerging malware attacks by anticipating the moves of the opponent and by having eyes even in the back?

DeepGuard detection technology is just like such a goal keeper. Continuously, DeepGuard technology is at the top of detection rate studies. The multi-layered protection is your winning team with a super goalie and the best defense team. This means that you and your business can be safe and secure in the knowledge that your goalie foresees and prevents the attacks, keeping your goal clean.

F-Secure Client Security uses DeepGuard, and can also be enhanced with Software Updater. It offers uncompromised security with minimal impact on performance.

Don’t ruin our trust in the update process!

We can see signs of a disturbing trend. Nowadays there is a built-in update process in almost every software product, and the automatic updates are essential for our devices’ security. The main driver to implement them was to be able to reach out quickly when vulnerabilities are discovered. And most users got the message. We understand the need for updates and let them be installed promptly. This is great from security point of view. So I’m very sad to see increasing misuse of users’ trust in the updates. Apple is making headlines right now with the “Error 53 scandal”. In short, upgrading to iOS 9 may brick your device, that is render it totally useless, if the new system detects that an unauthorized repair has been performed. The official reason is that Apple wants to protect the user’s data against attacks involving tampering with the device. The new functionality does however smell to high heaven. Apple has already a bad reputation for keeping its ecosystem closed and tightly managed, and this incident just feeds that reputation. It doesn’t take a genius to figure out that a move like this also benefits authorized Apple service companies over unauthorized. Bashing Windows 10 is also popular right now. I’m not going into all the security and privacy issues here. But I think the way Microsoft is pushing out Windows 10 to users of previous versions is disturbing. Yes, the automatically distributed upgrade is convenient, if you want to upgrade. And as said, upgrading is usually good from security point of view. But people may have tons of valid reasons to postpone the upgrade, and this is where things get nasty. Several gigabytes are downloaded anyway and use up disk space in vain. Language in the upgrade dialog suggests you have to upgrade. And it starts all over even if you decline, clean up and disable the updates. Even worse, now the upgrade may even start automatically without your consent! People are raging over these incidents because they cause major inconvenience and interferes with your ability to use a product you have purchased. But another at least equally severe side effect is that every case like this undermines peoples’ trust in update services. I bet people with a bricked iPhone will be hesitant to install new versions of iOS in the future. And my opinion about Microsoft’s update service has definitively changed while defending a touch-screen computer with Windows 8.1 from the upgrade. Yes, I have tried Windows 10 on it. No, it didn’t work properly so I had to roll back to 8.1. So to conclude. Rapid updates are more important than ever. Therefore it is very sad to see companies misuse the update channels to roll out features and versions that are designed mainly to boost their own business. It has caused permanent damage if people to a larger extent decline updates or try to block update systems that can’t be disabled.   Micke   PS. There’s some good news for people who want to stay on their previous Windows versions. There is a registry setting that can be used to prevent the upgrade.

Safer Internet Day

What are your kids doing for Safer Internet Day?

Today is Safer Internet Day – a day to talk about what kind of place the Internet is becoming for kids, and what people can do to make it a safe place for kids and teens to enjoy. We talk a lot about various online threats on this blog. After all, we’re a cyber security company, and it’s our job to secure devices and networks to keep people protected from more than just malware. But protecting kids and protecting adults are different ballparks. Kids have different needs, and as F-Secure Researcher Mikael Albrecht has pointed out, this isn’t always recognized by software developers or device manufacturers. So how does this actually impact kids? Well, it means parents can’t count on the devices and services kids use to be completely age appropriate. Or completely safe. Social media is a perfect example. Micke has written in the past that social media is basically designed for adults, making any sort of child protection features more of an afterthought than a focus. Things like age restrictions are easy for kids to work around. So it’s not difficult for kids to hop on Facebook or Twitter and start social networking, just like their parents or older siblings. But these services aren't designed for kids to connect with adults. So where does that leave parents? Parental controls are great tools that parents can use to monitor, and to a certain extent, limit what kids can do online. But they’re not perfect. Particularly considering the popularity of mobile devices amongst kids. Regulating content on desktop browsers and mobile apps are two different things, and while there are a lot of benefits to using mobile apps instead of web browsers, it does make using special software to regulate content much more difficult. The answer to challenges like these is the less technical approach – talking to kids. There’s some great tips for parents on F-Secure’s Digital Parenting web page, with talking points, guidelines, and potential risks that parents should learn more about. That might seem like a bit of a challenge to parents. F-Secure’s Chief Research Officer Mikko Hypponen has pointed out that today’s kids have never experienced a world without the Internet. It’s as common as electricity for them. But the nice thing about this approach is that parents can do this just by spending time with kids and learning about the things they like to do online. So if you don’t know what your kids are up to this Safer Internet Day, why not enjoy the day with your kids (or niece/nephew, or even a kid you might be babysitting) by talking over what they like to do online, and how they can enjoy doing it safely.

Virdem malware, old viruses, Malware Museum

Step back in time to when hackers were just having fun

What's so fun about old malware? In just four days more than a hundred thousand people have visited The Malware Museum -- an online repository of classic malware, mostly viruses, that infected home computers in the 1980s and 90s. Working with archivist Jason Scott, Mikko Hyppönen -- our Chief Research Officer -- put together 78 examples finest/worst examples of old-school malware that includes emulations of the infections with the destructive elements removed so you can enjoy them safely. "I only chose interesting viruses," Mikko told BBC News. The result is "nerdy nostalgia," says PC Magazine's Stephanie Mlot. The exhibits feature clunky ASCII graphics, pot references and obscure allusions to Lord of the Rings. While an early ancestor of ransomware like Casino was willing to ruin your files and call you an "a**hole," it wasn't trying to extort any cash out of you. That's because the creators of these early forms of digital vandalism were amateurs in the truest sense of the world. They did it for the love of mayhem. We long for the days of "happy hackers," as Mikko calls them, because the malware landscape today is so ominous. "Most of the malware we analyze today is coming from organized criminal groups... and intelligence agencies," Mikko explained. To keep the memories of the good old days alive, we're going to make t-shirts celebrating some classic malware. And we'd like you to choose which viruses we should commemorate. CRASH V SIGN FLAME CASINO PHANTOM (Image via @danooct1) [polldaddy poll=9302985] If you appreciate the Museum, Mikko asks that you contribute to the Internet Archive. You can learn more about Malware from Mikko's Malware Hall of Fame. Cheers, Sandra
