It’s summer holiday season, when people pack up their smartphones and tablets, sunscreen and tank tops and set off for a change of pace. With connected devices it’s never been easier to find one’s way around, record memories, and stay in touch with friends back home.
When traveling it’s convenient to use public WiFi hotspots in places like airports and restaurants, Our Security Advisor Sean Sullivan says that public WiFi networks should be thought of as just that: public.
Because you’re sharing the network with strangers, there’s the risk that someone is using readily available software that snoops on what you’re doing.
“It may feel private because you’re using your personal device, but it’s not,” he says.
Sean advises against doing anything via public WiFi that you wouldn’t want an eavesdropper to know – including logging into accounts with passwords. “I use public WiFi happily for a topic I would discuss with a friend on the metro. Banking, I do at home,” he says.
Here’s a quick look at how people feel about traveling with their devices and how to stay safe online when you’re on the road.
Here are some more tips that will keep you secure wherever you may roam:
• Don’t let your device connect to public WiFi spots automatically.
• Delete out the WiFi access points you’ve used when you arrive home.
• Don’t be logged into apps you don’t need while traveling.
• 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.
• Be aware of your surroundings and anyone who could be trying to peek over your shoulder.
• Use a unique password for each account.
• For laptops, disable file sharing and turn on the firewall, setting it to block incoming connections.
• Use a VPN (virtual private network) if possible, which secures your connection even on public WiFi.
• Use a travel router with a prepaid SIM card for your own personal WiFi network.
• At the very least, watch for the padlock and “https” in the address bar for any site with your personal information. If they’re not there, avoid the site.
• A good general rule: Assume anything you do over public WiFi is part of a public conversation.

Many people feel that some platforms are more secure than others. And while there may be some truth in that, what’s far more common is that operating systems offer users security features that people choose to use, or ignore. As Micke has pointed out in the past, behavior is often more important for security than product features. So someone with an Android device that updates all the software, sets it up to keep the device and data in their control, and knows how to avoid risky behavior that hackers look for will keep their data safer than an iPhone user that’s never even looked at the settings for their device. And based on what we saw at AltConf2016 – a developer event that mirrored Apple’s last WWDC – it looks like many iPhone and iPad users are making some pretty basic security faux pas. So here’s a few tips iPhone and iPad users can use to protect their devices and data. Don’t forget to forget Wi-Fi networks Unlike Android and Windows Phone, iOS devices don’t let you see your Wi-Fi history. It might not seem like it, but periodically cleaning out your Wi-Fi history is important. We’ve shown in the past that many people configure their devices to automatically connect with Wi-Fi hotpots they’ve connected with before. This leaves them exposed to hackers spoofing Wi-Fi hotspots (which is surprisingly simple and inexpensive to do). So if you’re an “auto-connector”, you should always remember to “forget” public Wi-Fi networks that you use in the odd café, hotel, or restaurant you visit. Because iOS devices don’t let you see your network history, you can’t pick and choose old networks you want to forget. So iOS users have two options: either forget a Wi-Fi network before you leave and walk out of range, or do a periodic network reset to clean out your entire network history. Don’t name your device after yourself During AltConf2016, F-Secure set up a Wi-Fi hotspot to see whether or not people would connect to any available free Wi-Fi. And as we’ve seen in the past, people take their Wi-Fi wherever they can get it. While many people connected and disconnected frequently, it was clear that lots of those people seem to name their device’s after themselves – approximately 80% of the devices that connected included a first name as part of the device identifier. And out of that 80%, 70% of them were iOS devices (Android and OS X devices constituted the remaining 30%). Now, hackers won’t really need this information to “pwn” their victims. But little tidbits like these are great for scams that use social engineering. Fraudsters and tricksters can use something as simple as this to manipulate people as part of a larger scam. It’s tough to say why personalizing devices seems more popular among iOS users than their Android/Windows counterparts. And having unique device names helps keep them separate on, say, a family’s Wi-Fi network that can have multiple people using it at any one time. But using initials or some other way to differentiate them is a better way to personalize your device without necessarily giving tech-savvy fraudsters the opportunity to learn something they can use to scam you. Use app restrictions (they're not just for kids) Earlier in the year, F-Secure Security Advisor Sean Sullivan recommended people change their iOS settings to take advantage of the various restrictions you can use. You can check out his blog post about it here, but basically, using iOS’ restrictions can create safeguards against malicious apps or attacks that try to trick your device into sharing information without your knowledge. Attackers use apps and processes that can run without requiring direct action from users (such as cloud storage services) to steal data. It’s something often seen as part of corporate cyber attacks, so it’s especially important to do this if you use your iPhone or iPad for work. And as my colleague pointed out in this recent blog post, you should already be using two-factor authentication and strong, unique passwords. [Image by Kārlis Dambrāns | Flickr]
What's easier than typing, clicking or even swiping left? For most of us, speaking. Until we can get actual USB ports in our brain, our mouths may be the quickest way to make our our desires known to our devices. And as it Internet of Things develops, we're going to be doing more and more talking to machines, including our thermostat, light bulbs and possibly even our drones. Fans of Siri and the Amazon Echo are already familiar with the benefits of a conversational interface. But, as with any new technology that gains widespread adoption, privacy and security concerns are inevitable. We spoke to F-Secure's Cyber Gandalf Andy Patel about what users of voice-activated technology should know as they make the leap into this newer realm of connectivity that has long been imagined by science fiction visionaries from Philip K. Dick to Star Trek's Gene Roddenberry. So are these voice-activated devices listening all the time? Yes. In order for a device to react to a voice command without the user pressing a button to activate the feature, the device must listen all the time. How could this be used against us? If a device streams voice data to a server for processing, a few privacy and security implications arise. If the data is being streamed in an insecure way, it can be intercepted by a third party. If the speech data is stored insecurely, it can become compromised in the case of a data breach. It can also potentially sold to a third party. Speech is processed into text. That text might be stored, it might be associated with its source, and it could also be leaked. When the speech processing service returns data to the device that requested the processing, it could also be intercepted. Are the any real privacy concerns for owners of voice-activated devices? Some companies outsource their speech recognition services and cannot properly account for the processes and collection methods used by those companies. Along those lines, just last year, Samsung TV voice recognition made the news for recording owners' chatter. Voice command systems can also be maliciously hijacked. Last year, a group of French researchers demoed a method for remotely controlling Siri from a distance, using sounds that triggered Siri’s voice control, but that couldn’t be recognized by a human. So what will voice-activated technology look like in five or ten years? Big names are interested in voice control because they attach it to AI and machine learning systems -- which are, in turn, fed by the Big Data they’ve collected -- for an interactive experience. The end goal would be a scenario where you could ask your computer to perform arbitrary tasks in the same manner as on Star Trek.
We used to search holiday magazines to find the hotel that offered the biggest pool and then triple check that the hotel has air conditioning. If we were really picky, we wouldn’t look twice at a hotel that didn’t offer cable TV. Now we see the perfect summer holiday in a different light. We can’t possibly leave our smartphones, tablets and laptops behind. A survey by Energy Company E.ON revealed that the most important feature hotels must have to even be considered is free Wi-Fi. Why do we find it so difficult to disconnect ourselves from the digital world? Even when we’re sitting in the beautiful sunshine, sipping on cocktails and splashing in the sea? Partly our digital dependence is practical, of course. The web helps us navigate around our holiday destinations finding the best attractions, the coolest bars and most remote beauty spots. But if we’re honest, many of us would admit that we’re so digitally connected because we don’t want to miss anything happening on Facebook, Instagram, Snapchat, Twitter and all the other social apps filling our electronic wonders. We continue to check in, trying to make our friends jealous by posting the latest update about our perfect holiday. Now that we’ve settled that an internet connection is a top holiday priority, why don’t we just use our phone network? Simple: we’ve all heard the horror story of someone getting crazy high bill after spending just a few days in Spain. So, we’re constantly on the search for a local bar or café that offers free Wi-Fi. It’s a fantastic feeling to be wiser than our internet provider – they can’t spring us with unheard-of charges. But connecting to public Wi-Fi comes with its own risks, and, I would argue, scarier ones than an unexpected post-holiday bill. For example, take a look at this infographic. It shows the personal data that can be intercepted and the risks you face to your privacy when you connect to public Wi-Fi without using a VPN. If the thought alone of anyone being able to snoop on what you do online isn’t enough to want to run away from ever connecting to public Wi-Fi again, then think about the bigger risks. The worst case scenario here is you could become a victim of stalking, receive threats, or have your identity stolen. This might sound farfetched, but with what information you reveal on public Wi-Fi, is it worth the risk? If you use a VPN like Freedome while on public Wi-Fi, all your internet traffic will be encrypted. This means instead of your internet traffic connecting directly to the websites from your device, revealing exactly what you’re doing online to the Wi-Fi provider, the VPN will garble your internet traffic and keep what you’re doing online anonymous. You internet privacy and safety is our biggest concern here, and Freedome will definitely provide that security. But here’s a little extra to boost your internet love and consumption when on holiday abroad: When in another country, you might not be able to stream your favorite content from back home. But with Freedome VPN, you can be “virtually” back in your home country, accessing all your favorite content as if you never left.
