Criminals aren’t just targeting your PC anymore. Whether your on your tablet, phone, Mac or laptop, you’re being targeted for scams designed to get your private information and money into their pockets.
And there’s even more you can do to make sure you’re not leaving yourself vulnerable. How many of these SAFE tips are you already following?
1. Keep your system, browsers, applications and security software patched and updated. Our free F-Secure Health Check makes this easy.
2. Lock your cell phone, tablet and PC when they’re not in use.
3. Use unique, complex passwords for all of your most important accounts. Our Key app makes that easy.
4. Keep your email inbox organized and spam free so you’ll recognize suspicious emails when you get them.
5. Use official app stores to find new software for your mobile devices.
6. Check the reviews on any app before you install.
7. Check your apps permissions to see what you’re sharing. Our free Permissions app for Android.
8. Remember there’s no such thing as “private” on a social network. Your friends can share whatever you post with the world.
9. Use a VPN when connecting through an unsecured WiFi. Freedome by F-Secure gives your phone VPN protection.
10. Are you sharing your location without even realizing it? Your photos and your social media accounts may be announcing where you are to strangers. Check your settings.
11. Set up a separate, Java-free browser dedicated just to shopping and banking.
12. Always check your URLS before filling out a form. You’re looking for a padlock and https, which means secured, and that you’re on the domain you meant to be on.
13. Don’t let your device connect to public WiFi spots automatically and delete old WiFi access points you’ve used when you arrive home.
14. Check the credit card you use for online purchases regularly for unusual activity.
15. When using a business’s WiFi network, check with the establishment you’re at to make sure the network you log onto is really theirs, and not one a snoop has set up to trick you.
16. When at an ATM or using your devices in public, be aware of your surroundings and anyone who could be trying to peek over your shoulder.
17. In many countries you can use a travel router with a prepaid SIM card for your own personal WiFi network.
18. Assume anything you do over public WiFi is part of a public conversation.
19. Put masking tape over your webcam when you’re not using it.
20. Don’t share crucial identification information – Social Security number, account information, Mother’s maiden name—with sites you don’t know.
21. If you have any questions about a strange email you’ve received from your bank or credit card company, contact the institution directly, preferably by phone.
We’re glad you’re staying protected and hope you’ll consider F-Secure SAFE for complete protection for all your devices.
Adblocking made waves last summer after Apple announced that it would bake content blocking capabilities into iOS 9. Content blocking lets users filter out content that they don’t want to load, and in this case, it worked with Apple’s Safari web browser. And there’s one kind of content that typically irritates people more than anything else – ads. So Apple’s content blocking capabilities swiftly lead to adblocking on iOS devices, with many companies developing these apps to help secure and improve people’s web browsing experience. This includes F-Secure, who released a free adblocking app last September. Now, F-Secure Labs has written up a brief whitepaper explaining, in detail, how F-Secure Adblocker works. Without getting into too much detail, F-Secure Adblocker basically checks for information about web traffic with F-Secure Security Cloud (a cloud-based service that powers many of F-Secure’s security products). If F-Secure Security Cloud is able to identify the source of web traffic as an advertising server, it lets Adblocker know, and Adblocker can filter out the advertising content, leaving you with the information about sports, news, business, or whatever else you’re browsing for. Using Adblocker also speeds up your browsing, protects you from malvertising, and saves bandwidth for those of you trying to save money on your data plans. Not bad for a free app. Plus, it all operates in accordance with F-Secure’s Privacy Principles. F-Secure can’t connect the information about your web traffic with anything else about you, so you don’t have to worry about sharing information with companies looking to exploit your personal data. The paper is a quick easy read and gives you a comprehensive breakdown about how Adblocker works, so it’s worth checking out if you’re interested in learning how products being ad free can improve your web browsing experience.

Mikko Hypponen is one of the world’s most prominent cyber security experts. Described as a “virus hunter” in a Vanity Fair profile called “The Code Warrior”, Hypponen has spent nearly 25 years with F-Secure protecting people from computer viruses, worms, trojans, and other types of malware. In 2011, Hypponen travelled to Pakistan to meet the men behind the first known PC virus – Brain.A. [youtube https://www.youtube.com/watch?v=lnedOWfPKT0&w=560&h=315] The Brain virus was released in January of 1986, making January 2016 the 30th anniversary of this milestone in malware history. I thought it would be interesting to reach out to Mikko and ask him about other families of malware that standout as being noteworthy. So here’s Mikko’s list of some of the most infamous malware families (including viruses, worms, trojans, etc) that’ve pestered, frustrated, and even extorted computer users over the past few decades. 1990 Form – Form was a common computer virus identified in 1990, and for several years, was arguably the most prominent computer virus in the world. Spread through 3.5” floppy disks, it infected millions of computers throughout the world, and is possibly one of the most widespread viruses in history. 1992 Michelangelo – Michelangelo earns a place on the list for being the first truly global virus scare. It was named after the famous artist because the virus remained dormant until March 6 (the artist’s birthday), when it would awaken and overwrite sections of infected hard disks, thereby making the information inaccessible and the computer unusable. The virus was never particularly prominent compared to some of its contemporaries, but its destructive nature and subtlety helped spread Michelangelo Madness throughout the globe. 1995 Concept – Concept was the very first macro virus – a type of virus that infects applications such as Microsoft Word. It was a very prominent security concern in the mid-nineties, and even though it was successful in propagating itself organically during this time, it hasn’t been seen in over a decade. As the first macro virus, it was notable in that it spread by hiding itself as a Word doc and then infecting computers as those documents were shared. By using Word, it could use both Windows PCs and Macs to spread infections, as the software could run on both platforms. 1999 Melissa – Melissa, supposedly named after an exotic dancer, was a computer virus that sent infected Word documents to contacts in victims’ Outlook address book. While the virus was not designed to be particularly destructive, its rapid proliferation through the Internet wreaked considerable havoc on corporate servers and infrastructure. Some accounts claim that it infected twenty percent of computers globally, and the man eventually convicted of releasing the virus into the wild admitted to causing eighty million dollars in financial losses. 2000 Loveletter – Loveletter, also widely known as ILOVEYOU, was a prominent email worm that was able to spread itself throughout the globe in a matter of hours by promising victims a little bit of love. Disguising itself as a chain, love-themed email to recipients helped it quickly spread from its Filipino origin through Asia, Europe and North America. To this date, it is one of the largest malware outbreaks of all time, and responsible for an estimated 5.5 billion dollars of damage. 2001 Code Red – Code Red was the first fully-automated network worm for Windows. As in users would not have to interact with a machine in order to spread the infection. Code Red’s most infamous day was July 19th, 2001, when it successfully infected 300,000 servers. The worm was programmed to spread itself on certain days, and then execute distributed denial-of-service (DDoS) attacks on others, and was used against several different targets (including The White House). 2003 Slammer, Lovsan, and Sobig – Ok, so there’s three here and not just one. But they all occurred very close together, and unfortunately, all three were worms responsible for massive, global malware outbreaks. Slammer targeted servers so it’s presence wasn’t readily apparent to end users (save some lagging when they were attempting to access an infected server). Lovesan, however was able to infect end users running Windows ME or Windows XP, and use the infected machines in DDoS attacks. Sobig spread itself through email and network drives, and contained a trojan in order to cause more headaches for infected users. However, it appears that the trojan feature did not function as expected. These three worms infected millions of machines, and made headlines all over the world. 2004 Sasser – A computer worm that can be considered as the last large “hobbyist” outbreak. This is significant as it signaled the end of an era when most malware was written by people who were simply curious to see what the malware could do. Nowadays, malware has a more specific, insidious purpose, such as stealing information or making money. 2006 Warezov – A two-year email worm campaign perpetuated by professional criminals, Warezov gained notoriety for downloading new versions of itself from remote servers – sometimes as frequently as every 30 minutes, according to a 2006 interview with Mikko. 2007 Storm Worm (also called Small.dam) – Storm Worm was a trojan that was spread as an attachment to spam emails. But more importantly, it was a combination of complex and advanced virus techniques that criminals were able to use to make money by using infected machines as part of a botnet. 2013 Cryptolocker – A notorious ransomware family, Cryptolocker was spread through malicious email attachments, as well as the infamous Gameover Zeus botnet. Infected victims would find their hard drives suddenly encrypted, essentially locking them out of their devices and data until they paid a ransom to the perpetrators. While the FBI, in cooperation with other law enforcement agencies and security companies (including F-Secure), were able to disrupt the operation, the perpetrators were able to use Cryptolocker to extort about 3 million dollars from victims before being stopped. Other notable mentions include the 2005 Sony rootkit (for being distributed on Sony BMG CD-ROMs on their behalf), the still prominent Downadup worm from 2008 (for infecting millions, including armed forces of several countries and police departments), and the well-known Stuxnet virus from 2010 (for both its sophistication and its apparent state-sponsorship).

Today is Data Privacy Day (or Data Protection Day as it’s known in Europe). Unfortunately, that doesn’t mean you get gifts, so it hasn’t caught on in the same way as holidays like Christmas. But what you do get is the chance to take part in the conversation about how you see the boundaries that separate your public life from your personal life. So what do you have to say about this? And why is this topic so important anyway? Well, F-Secure Security Advisor Sean Sullivan posed this question to just over 1,000 people in the US and UK in 2014. While about 83% of respondents said they don’t have anything to hide (slightly more in the UK than the US), 89% said “no” (again, slightly more in the UK than in the US) when asked “Would you want to share everything about your life with everyone everywhere, all the time, forever?” [polldaddy poll=9289730] The point being – people think about privacy in different ways, and a lot of what they think is shaped by the conversations about privacy that we have. A recent F-Secure survey posed a variety of security and privacy related questions to almost 9000 people in 11 different countries. You can see the breakdown of some of the results below. When asked about whether they were concerned about data privacy, and if they changed their Internet habits as a result, many people disagreed with the statement (more Americans seemed concerned compared to other nationalities). So people are either unconcerned about their data privacy, or at least not enough to change their behavior. However, other questions focused more on particular threats to online privacy, and these responses indicated considerably more people are concerned about these threats. The majority of respondents said they avoided using public Wi-Fi – a well-documented security and privacy risk. And an overwhelming majority of respondents said they avoid installing apps asking for unnecessary app permissions (which are critical for controlling what apps can access what data). Avoiding using certain apps or services strikes me as an indication that people are concerned about these things. And they’re right to be worried about these things, which becomes more apparent when confronted with questions that highlights how vulnerable their online privacy actually is. I asked Sean about this, who pointed out the way we talk about things like privacy on Data Privacy Day/Data Protection Day is more significant that people might think. “In North America, we say Data Privacy Day. In Europe, we say Data Protection Day. They refer to the same thing, but represent it in different ways,” says Sean. “I want to protect my data because privacy is important to me. I don’t want everyone to know my phone number or my credit cards number, so I try and use services that don’t collect this information.” “It’s not because I’m emotionally attached to my personal space, even though that’s important, but I feel like that information could be used in ways that may be harmful. And that aspect isn’t always clear when people talk about online privacy.” Just over a year ago, Sean wrote that he’d like to ask people “Are there things in your past that are best left forgotten?” Maybe today is a good day to start talking about that.
