It’s a fact of life: once school is out, kids spend more time online. You may try to schedule when they can and can’t use the PC and use solutions like Parental Control to prevent some trouble. But simply limiting access to Facebook and YouTube and the rest of the online world is a limited strategy. The fact is whether it’s on a desktop, a laptop or a smartphone, most kids—or at least, most teenagers—can get online whenever they want.
That’s why we suggest spending a few minutes explaining the risks of cybercrime and online predators to your family. Of course, your kids will probably brush you off by repeating “I know, Mom (or Dad)” over and over, as if you’re trying to discuss the birds and the bees. So don’t go in unprepared. Check out these five quick tips to keep your kids and your PC safe until school resumes in fall.
1. Repeat the mantra “Links are not your friends”
Cybercriminals are aware that millions of people Facebook have plenty of time to kill. That’s why they’re spreading their scams with links described as “The Sexiest Video EVER” or “You’ll never believe this LOL.” When you’re bored and a link like that appears on a Facebook wall posted by a friend, it takes incredible will power not to click it. So repeat this mantra: If a link looks too good to be true, it is. Of course, this won’t always work. That’s why you should bookmark F-Secure’s free Browsing Protection. If your son or daughter feels they must click, have them check it out first. What else do they have to do? It’s summer.
2. Keep up with the updates
If you don’t keep your system software up to date, you risk inviting predators into your PC. Monthly updates for Windows, Adobe Reader, iTunes, and other applications are essential for your online safety. F-Secure’s Health Check makes this time-consuming process easy. Run it once a month and save yourself some major headaches.
3. Tell your kids that you will handle installing software
Once you’ve run Health Check and made sure you’re protected, there’s no need for your kids to install any random software that pops up. So tell your child that it’s mom or dad’s job to install new software, no matter what pops up. Once you’re home and had a nice summer beverage, check out the software. Google it to see if it’s a legitimate and then decide if it’s worth your hard drive space. Nothing ruins a nice summer afternoon like getting tricked into installing malware on your PC.
4. Make clear what information your kids should not share
Most kids know more about Facebook than you’d ever want to. They know how to add and erase apps or how to block this user and not that one. But they may not know what they should NOT share. Tell your kids that they should never private information—email addresses, phone numbers, home addresses—on any social network. They should also avoid posting information about their schedule, especially vacations or details about when their parents will be home or not. Your kids need to know that no matter how private their settings tell them they are, anything they post on a social network should be considered as public as the front page of a newspaper—if they know what that is.
5. Let them know that you are watching
You need to know which social networks your children are on. If you have the time and patience, it’s a good idea to start a profile on the site and become their friend or follower. It doesn’t take long, maybe five minutes per site. You can’t watch your child every minute. But if they get the sense that you could be watching, it can only help them think before they click or post.

At Re:publica 2015, our Chief Research Officer Mikko Hypponen told the main stage crowd that the world's top scientists are now focused on the delivery of ads. "I think this is sad," he said. [youtube https://www.youtube.com/watch?v=pbF0sVdOjRw?rel=0&start=762&end=&autoplay=0] To give the audience a sense of how much Twitter knows about its users, he showed them the remarkable targeting the microblogging service offers its advertisers. If you use the site, you may be served promoted tweets based on the following: 1. What breakfast cereal you eat. 2. The alcohol you drink. 3. Your income. 4. If you suffer from allergies. 5. If you're expecting a child. And that's just the beginning. You can be targeted based not only on your recent device purchases but things you may be in the market for like, say, a new house or a new car. You can see all the targeting offered by logging into your Twitter, going to the top right corner of the interface, clicking on your icon and selecting "Twitter Ads". Can Twitter learn all this just based on your tweets and which accounts follow? No, Mikko said. "They buy this information from real world shops, from credit card companies, and from frequent buyer clubs." Twitter then connects this information to you based on... your phone number. And you've agreed to have this happen to you because you read and memorized the nearly 7,000 words in its Terms and Conditions. Because everyone reads the terms and conditions. Full disclosure: We do occasionally promote tweets on Twitter to promote or digital freedom message and tools like Freedome that block ad trackers. It's an effective tool and we find the irony rich. Part of our mission is to make it clear that there's no such thing as "free" on the internet. If you aren't paying a price, you are the product. Aral Balkan compares social networks to a creepy uncle" that pays the bills by listening to as many of your conversations as they can then selling what they've heard to its actual customers. And with the world's top minds dedicated to monetizing your attention, we just think you should be as aware of advertisers as they are as of you. Most of the top URLs in the world are actually trackers that you never access directly. To get a sense of what advertisers learn every time you click check out our new Privacy Checker. Cheers, Jason
F-Secure Labs reported this week on a new WhatsApp scam that’s successfully spammed over 22,000 people. Spam seems to be as old as the Internet itself, and is both a proven nuisance AND a lucrative source of revenue for spammers. Most people don’t see what goes on behind the scenes, but spammers often employ very sophisticated schemes that can expose web surfers to more than just ads for Viagara or other “magic beans”. Spam typically tries to drive Internet traffic by tricking people into clicking certain websites, where scammers can bombard unsuspecting web surfers with various types of advertising. Profit motives are what keep spammers working hard to circumvent spam blocks, white lists, and other protective measures that people use to try and fight back – and it can pay off. Numerous spammers have been indicted and suspected of generating hundreds of thousands of dollars in revenue from their spam campaigns, with one study projecting that spammers could generate in excess of 3.5 million dollars annually. While most spam circulates via e-mail, the popularity of services like WhatsApp is giving spammers new resources to exploit people, and new ways to make money. Here’s a few ways spammers and cyber criminals are using WhatsApp to make money off users: Following Malicious Links: One way that cyber criminals use WhatsApp to scam people is to trick them into following malicious links. For example, a recent scam sent SMS messages to WhatsApp users telling them to follow a link to update the app. But the message was not from WhatsApp, and the link didn’t provide them with any kind of update. It signed them up for an additional service, and added a hefty surcharge to victims' phone bills. Sending Premium Rate Messages: Premium rate SMS sending malware was recently determined by F-Secure Labs to be the fastest growing mobile malware threat, and WhatsApp gives cyber criminals a new way to engage in this malicious behavior. Basically the users receive a message that asks them to send a response – “I’m writing to you from WhatsApp, let me know here if you are getting my messages”, “Get in touch with me about the second job interview”, and various sexual themed messages have all been documented. Responding to these messages automatically redirects your message through a premium rate service. Spanish police claim that one gang they arrested made over 5 million euros using this scheme – leaving everyday mobile phone users to foot the bill. Manipulating Web Traffic: A lot of spam tries to direct web traffic to make money off advertising. As you might imagine, this means they have to get massive numbers of people to look at the ads they’re using for their scams. Scammers use WhatsApp to do this by using the app to spread malware or social engineer large numbers of people to visit a website under false pretenses. F-Secure Labs found that people were being directed to a website for information on where they could get a free tablet. In March there was a global spam campaign claiming people could test the new WhatsApp calling feature. Both cases were textbook scams, and instead of getting new tablets or services, the victims simply wasted their time spreading misleading spam messages and/or exposing themselves to ads. WhatsApp and other services are great for people, but like any new software, requires a bit of understanding to know how to use. Hopefully these points give WhatsApp users a heads up on how they can avoid spam and other digital threats, so they can enjoy using WhatsApp to chat with their friends.

Espionage – it’s not just for James Bond type spies anymore. Cyber espionage is becoming an increasingly important part of global affairs, and a threat that companies and organizations handling large amounts of sensitive data are now faced with. Institutions like these are tempting targets because of the data they work with, and so attacks designed to steal data or manipulate them can give attackers significant advantages in various social, political and industrial theaters. F-Secure Labs’ latest malware analysis focuses on CozyDuke – an Advanced Persistent Threat (APT) toolkit that uses combinations of tactics and malware to compromise and steal information from its targets. The analysis links it to other APTs responsible for a number of high-profile acts of espionage, including attacks against NATO and a number of European government agencies. CozyDuke utilizes much of the same infrastructure as the platforms used in these attacks, effectively linking these different campaigns to the same technology. “All of these threats are related to one another and share resources, but they’re built a little bit differently to make them more effective against particular targets”, says F-Secure Security Advisor Sean Sullivan. “The interesting thing about CozyDuke is that it’s being used against a more diverse range of targets. Many of its targets are still Western governments and institutions, but we’re also seeing it being used against targets based in Asia, which is a notable observation to make”. CozyDuke and its associates are believed to originate from Russia. The attackers establish a beachhead in an organization by tricking employees into doing something such as clicking a link in an e-mail that distracts users with a decoy file (like a PDF or a video), allowing CozyDuke to infect systems without being noticed. Attackers can then perform a variety of tasks by using different payloads compatible with CozyDuke, and this can let them gather passwords and other sensitive information, remotely execute commands, or intercept confidential communications. Just because threats like CozyDuke target organizations rather than individual citizens doesn’t mean that they don’t put regular people at risk. Government organizations, for example, handle large amounts of data about regular people. Attackers can use CozyDuke and other types of malware to steal data from these organizations, and then use what they learn about people for future attacks, or even sell it to cyber criminals. The white paper, penned by F-Secure Threat Intelligence Analyst Artturi Lehtiö, is free and available for download from F-Secure’s website. [ Image by Andrew Becraft | Flickr ]
